In an ideal world, there would be no need for battery packs. Yet, the reality is that battery life is still a pain point for many users, even those with flagship devices.

Getting through the day with some power remaining requires some serious discipline, which is tough if you’re used to spending all your time in group chats, mindlessly scrolling through. playing games or on yet another video call.

That’s where our list of the best battery packs and portable chargers comes in. They’ve been around for years, which thankfully means there are thousands of great options to pick from, and some are now starting to include seriously high capacities along with support for high-wattage USB-C Power Delivery. These two things together, mean that you can even charge your laptop.

Let’s not forget other gadgets, too. Bluetooth headphones, action cameras and drones can all benefit from a top-up, especially when you’re travelling.

So, without further ado, here’s our selection of the best power bank options around to deliver juice back to your gadgets.

Anker 737

Shargeek Storm2 Slim

Excitrus 105W Power Bank Ultimate

Anker 325

Tecknet 10k

Our Top Pick: Best Portable Charger

Anker 737

With a luxurious feel, insane charging speeds and a useful display, the Anker 737 is about as good as it gets.

If you’re looking for the best of the best, the Anker 737 might be exactly that. Not only can it deliver a staggering 140W fast charge over USB-C, but it can also be recharged at the same rate. This means that you can refill its ample 24,000 mAh capacity in less than an hour, with a compatible charger.

It’s also built exceptionally well and feels like a luxury item, with a lovely texture on the sides and a full-colour display.

Now, you might not think that you need a display on a power bank, but in practice, it comes in very handy. It’ll tell you the output on each port, the remaining charge, and how long it’ll last at the current charge rate.

Sure, it’s expensive, but considering the specifications, it’s a fairly reasonable asking price. If you’re looking to juice up one of the latest super-fast charging smartphones at full speed, this is the tool for the job.

Shargeek Storm2 Slim

If you want a power bank that makes a statement, this is the one for you.

  • The coolest-looking power bank ever
  • Incredibly detailed display and menus
  • 100W output and 20,000 mAh capacity

Quite simply, this is the most impressive-looking power bank we’ve ever come across. It has a semi-transparent chassis that allows you to look at the components inside, along with a colour display that’ll reveal all the technical details.

It’s a wonderfully geeky design, that lands somewhere between a cyberpunk aesthetic and early 2000’s nostalgia. We absolutely love it.

If you thought having a display on your power bank was overkill, strap in, because the Shargeek takes things to the next level. There’s a full menu system on this thing, allowing you to check out individual cell voltages, temperatures and more. You can even set timers to avoid wasting your charge.

Of course, none of this matters if it’s not a solid power bank, and thankfully it very much is. With a 20,000 mAh capacity and the ability to deliver 100W fast charging over USB-C, it’s ready for anything. You’ll have to be prepared to fork out some cash, though.

Excitrus 105W Power Bank Ultimate

Serious power and portability, combined with unassuming looks. This could be the sweet spot for a lot of people.

This option from Excitrus has a much more subtle design, and if you didn’t know better, you could easily mistake it for any other run-of-the-mill power bank.

On the inside, though, it’s extremely capable. It can deliver 87W from its USB-C port, while simultaneously outputting 18W over USB-A.

That’s enough power to charge a Surface Laptop 4 and a Google Pixel 6 at full speed simultaneously.

What’s more, it’s very compact and lightweight for its specification, along with being reasonably priced.

Anker 325

If you’re not overly concerned with fast charging, this option offers loads of capacity and excellent build quality at a bargain price.

If you’re not so bothered about fast charging and just want an affordable power bank that will keep you charged up for days on end, the Anker 325 is likely the one to pick.

It comes at a very affordable price but still benefits from Anker’s excellent build quality and renowned reliability.

The massive 20,000 mAh capacity is enough to charge an iPhone over four times, so it’ll keep you going for a really long time.

It’s also very slim and lightweight, for its capacity, so it won’t weigh you down too much when you’re out and about.

Tecknet 10k

Amazingly cheap and reasonably quick, this one gets things done without breaking the bank.

If you’re after something cheap and cheerful, we’ve had great results with this option from Tecknet.

It’s not the largest capacity, nor does it have the most impressive speeds, but it comes at a bargain price. and it’s still a touch speedier than the Anker 325.

The 20W output is fast enough to charge phones like the iPhone 12 and Google Pixel 6 at full speed. So if you’re using a basic power bank, you’ll see a definite jump in charging times with this product.

It’s super thin and lightweight and can be charged via USB-C or Micro USB, so it’s easy to top up when the time comes.

How to choose a portable charger

Choosing a portable charger can feel like a monumental task, there are just so many to choose from. With such a variety of sizes, capacities, styles and specifications on the market, it’s especially hard to find the right one for you.

To help narrow down your choices, here are a couple of things we recommend thinking about before you commit to a power bank.

How much capacity do you really need?

It can be tempting to go for the largest capacity available; the more juice the better, right? Well, these high-capacity chargers also tend to be heavy and bulky, so they can be a bit of a pain to carry around with you. We recommend taking a moment to think about the situations you face that normally call for a power bank. If you’re camping out in the wilderness for days on end, then a giant capacity charger may be just what you need. but if you’re just trying to get an extra bit of battery life to see you through your commute, you’d likely be happier with a slimmer and more lightweight solution.

What do you need to charge?

While pretty much any power bank will charge your phone, laptops, in particular, are where things get more complicated. Most USB-C-powered laptops will require a high-wattage USB-C Power Delivery (PD) specification. It all depends on the laptop model, but generally speaking, for laptops, you’re likely to want 60W PD spec or above, especially if you want to charge the laptop while it is in use. Check your model’s specifications to ensure you get a power bank that’s up to the task.

If you’ll only be charging phones or tablets, then any charger will work, but be aware that not all are created equal. If you want to take advantage of fast charging then it’s worth paying attention to the specs to ensure that your device will be compatible. Samsung phones seem to be especially picky when it comes to fast charging, but so long as you cross-reference your manufacturer’s charging specifications with the power bank’s specifications, it shouldn’t be too hard to figure out.

Review: Gatcepot 24,000mAh Portable Charger

Having a power bank with a large power capacity also means that the build behind may not be as stable.

This is because when a power bank has a higher power capacity it also means that the conversion rate will not be as good. However, this case isn’t prevalent with all high capacity power banks, it’s certainly more likely to happen.

Although, it’s always too good to look on the bright side of what comes with power banks that have large capacities.

You’re almost always going to get more charging capabilities that lower battery capacity power banks simply don’t have.

This is the Gatcepot 24,000mAh power bank. It rings true to some to some of the common pitfalls that high capacity portable chargers are known for but it does well with all the raised standards that come with a high power capacity.

Similar Power Banks:

Power Capacity

The power capacity suffers quite a lot and Gatcepot states that the conversion rating of this power bank is 70%.

That’s a lot of power capacity that’s gone down from an initial power level and even though this info is straight from the Gatcepot, the 70% conversion rating is most likely what you’re getting if you’re taking full advantage of all the charging ports.

With that said, since the power banks do have 3 charging ports, we’re going to assume that you’re going to use all of them and with that, you’re going to be receiving a power capacity of 16,800mAh.

Yeah, it’s nowhere near the power level of 24,000mAh that this power bank is supposed to have but that’s what it’s capable of when it’s being used without any holdback.

However, if you’re charging 1 or 2 devices only then the Output power capacity can very well be higher than 16,800mAh. Consider the 16,800mAh Output capacity to be the power capacity that you’d receive if you were using all 3 charging ports at once.

So even with an Output capacity of 16,800mAh, it’s capable of charging smartphones, tablets, and any other device that you plan on charging with constant power.

For smartphones, this power bank can cut through them like butter as it can charge most smartphones 5 times or over.

As for tablets, if you’re charging tablets that have lower battery capacities than the norm like the iPad Mini version then you’re going to be able to get 1-2 full charges.

If there is one thing about high power capacity portables, it’s that they’re capable of charging devices multiple times even when their Output power capacities fall short.

DevicesGatcepot 24,000mAh Portable Charger (Output Capacity = 16,800mAh )Phone CapacityGatcepot 24,000mAh Left Over Capacity after One Charge

Output Charging: Port 1: 5V/1A | Port 2: 5V/2.1A | Port 3: 5V/2.4A | Max Output: 5.5A

The strongest part of this power bank is the charging speeds.

It has 3 Output charging ports and each of them gives a different charging speed. It’s important to know that the Max Output of the power bank is 5.5A, so you can use the max potential of each of the charging ports, and overall it will reach the Max Output of 5.5A.

Port 1:

It’s best to avoid this port because it only Outputs 1 Amp of charging speeds, which is a very slow charging speed.

juice-up, 120w, powerbank, wireless, 24000mah, um1106

The logic here is that you’d use smartphones for these charging ports but even for smartphones this port isn’t very acceptable. If the other 2 charging ports aren’t being used by tablets or any other device that requires a high Amperage needs, then it’s best to avoid this port.

If you have no choice to use this port, then it’s available to use.

Port 2:

The second port is a level up from the first port as it’s able to Output 2.1 Amps.

This charging port and the 2.4A charging port are the ports that you want to use the most because they’re able to deliver more charging power. It’s best to use this charging port for all your devices, this especially goes for tablets, and if you’re not using a tablet with this port, then use your smartphone.

Port 3:

The 3rd port can deliver a Max Standard charging speed of 2.4 Amp and this means that it will be able to charge tablets at their max speeds. This port is great for all the devices that you want to charge as fast as possible. The same goes for the 2nd port.

We like the Output charging speeds because 2 out of 3 of them can give a very good charging speed and they’re able to support a high power capacity with a great charging experience.

Input Charging: 5V/2.1A

The Input charging speed is quite good with it being able to recharge at a max speed of 2.1 Amps and if you’re using a 2.1 Amp wall charger or higher then it’s going to be able to recharge within 8-10 hours. If you’re using anything lower, then it’s going to take the power bank a full 24 hours to fully recharge.

Size and Weight

So, of course, it’s going to be heavy and large with the power bank having a large power capacity and plenty of charging ports.

The length is 6.7 inches, the width is 3.2 inches and it’s 0.9 inches in thickness.

It’s a large power bank so it can be quite cumbersome to hold, not only that, the power bank weight 15 ounces, so it’s nearly a pound.

This isn’t the type of portable that you’re going to hold or at least if you do hold it, it isn’t going to feel the best because it’s heavy and large. So it’s best to take it anywhere you want but you’re going to ultimately set it down and use it.

Functional Components

The power bank follows very similar design features that other high power capacity power banks also feature. All 3 Output charging ports are on a single side, and along with the Output charging ports are 2 LED flashlights. The power button can found on the light side and there’s an LCD for the power capacity.

It’s strange to have 2 flashlights and it’s, even more, to have a flashlight with a power bank that already has quite a poor conversion rate.

The flashlights can be turned on by holding down the power button and turned off by holding the power button again. Charging begins when you connect a device to the power bank and it can shut-off automatically if there aren’t any devices connected to the charger.

The LCD is very convenient as it shows power capacity in a numeric value, so you can get a more precise reading of what power capacity you currently have.

Structure and Material

However, it’s just not any plastic, it’s ABS which is a stronger version of plastic.

You shouldn’t fool but the structure and material, though, as the power bank is still very heavy and it can take damage if you were to drop it on hard flooring.

With that said, it’s capable of being used every day.


There’s nothing special about the tech build of this power bank and that’s the usual case with high-capacity portable chargers; they simply don’t feature very special charging tech, but of course, there’s always the safety tech that keeps your devices safe during charging.

Although, there are no Panasonic battery cells and or cooling technology that’s able to keep the conversion during charging at a good standard.


It’s a reliable enough high capacity power bank but the power capacity suffers as the conversion rating isn’t that good.

This then leaves the power bank with a power capacity that isn’t nearly as impressive as the initial one at 24,000mAh.

With that said, the power capacity can still lend plenty of charges to smartphones and a few to tablets. Even so, it’s just not as good as being able to use the power capacity that the power bank is supposed to have.

So the power capacity may not be that impressive but the charging capabilities with its 3 charging ports and how there are 2 charging ports capable of charging at 2 Amp is nice.

Portability can be a problem, so it’s best to set it down and use it for the most reliable user experience.



The Output power capacity falls shorter than the initial one as the conversion rate is poor and a very large chunk of power is lost.

The charging capabilities are good with the power bank having 3 charging ports and a max Output of 5.5A. The recharge rate isn’t that bad as long as you’re using a 2.1 Amp wall charger or higher.


It’s large and heavy, so it’s not best to hold it while you’re using it. Most of the time, you’re going to have to set it down and use it. It has 2 LED flashlights which are strange. It has an LCD to show power capacity in a percentage method.


The build with its structure and material is quite good as the power bank uses very few separate pieces and it’s made out of ABS plastic. The tech builds well to use some work to improve charging capabilities.


Its reliability falls a little short as the power capacity isn’t what it should be.

Specs of the Gatcepot 24,000mAh Portable Charger:

Port 1: 5V/1A

Port 2: 5V/2.1A

Port 3: 5V/2.4A

Max Output: 5.5A

  • Input: 5V/2.1A Via Micro-USB Input
  • LED Power Indicators: LCD Display Show power capacity in Percentage
  • Size: 6.7 x 3.2 x 0.9 inches
  • Weight: 15 Ounces


The Gatceput power bank is an example of a high capacity power bank that isn’t great just because it delivers a high power capacity.

This is because it’s not even able to deliver its power capacity due to its poor conversion rate. It’s not always the case that high-capacity portable chargers promise grandeur and fall short; but in this case, it somewhat is.

If you can get past the poor conversion rate and very large size and heavyweight, then this power bank can deliver what you’re looking for.

Review: LQQB Storage 24,000mAh Power Bank

A high power capacity is one of the best traits that a power bank could have because it makes a portable charger more useful.

The reason for that is because a high power capacity is able to charge lots of devices to their max power many times over and the use of a lot of power means that the charger uses lots of USB ports so you can charge lots of devices at once.

However, as awesome as these sorts of features sound, the details such as the power capacity’s conversion rate or the charging speed of the ports is what’s most important because those are things that you’re actually going to be experiencing.

Other Types of 20,000mAh Power Banks:

Power Capacity:

The power capacity of this LQQB Storge power bank starts at a high 24,000mAh and the conversion rate of this charger can vary depending on how you’re using it.

That’s because it uses 3 USB ports and the Max Output of the power bank is 5.5A. Using 3 ports at the same time will worsen the conversion of energy from the charger and to your device and that means you would get less of an Output power capacity that you can actually use.

With that said, if you’re using 1 or 2 USB ports then conversion of energy will be more normalized.

Let’s calculate what amount of power capacity you’ll receive that you’ll actually be able to utilize.

3.7 x 24,000 = 88,800 / 5 = 17,760

LQQB Storage 24,000mAh Power Bank (Output Power Capacity = 7,400mAh)Phone CapacityLQQB Storage 24,000mAh Left Over Capacity after One Charge

You’re most likely going to be receiving an Output power capacity of 17,500mAh and even though it’s quite a bit down from the initial power capacity, it’s still a lot of power.

Smartphones will have no problem charging to their full power with this power bank and it doesn’t really matter what smartphone you’re charging.

A Google Pixel XL with its massive battery capacity of 3,450mAh can charge to its full power 5 times or a Galaxy S8 with its 3,000mAh battery can charge to its full power about 5 times too.

So if you’re charging a smartphone that has a low capacity such as an iPhone SE with its 1,624mAh capacity, it can charge to its full power about 11 times.

Capacity for Tablets

The power capacity is also great for charging tablets too because you can charge an iPad Mini 2 about 2 times to its full power or an iPad Mini 4 can charge to its full power about 3 times.

Even charging full-sized tablets such as an iPad Air can result in it being filled with full power about 2 times with this LQQB Storage power bank.

Output Charging:

The charging capabilities of this power bank are really good. Each of the ports has different charging speeds but in the end, you’re able to use the max capabilities of each of the ports at the same time.

V/2.4A Port

The USB port that has the fastest charging speed is 5V/2.4A and this is a port that you’re going to want to use first because it has a charging speed that is able to charge most devices at their max charging speed.

That is true when it comes to charging tablets and most smartphones.

However, it’s important to know that this power bank does not feature Quick Charge and therefore Quick Charge compatible smartphones are not able to charge at their max charging speeds.

V/2.1A Port

The next port has a charging speed of 5V/2.1A and it’s slightly slower than the 2.4A port and should be used for the 2nd device that you plan on charging when the 2.4A port is being used.

V/1.0A Port

Lastly, there’s the USB port with 5V/1.0A charging speed and it’s the slowest charging speed that this power bank offers. The 1 Amp port should only be used when you’re already using the 2.4A and the 2.1A port.

All of the ports can be used at the same time and at their max charging speed capabilities because the max Output of the LQQB Storage power bank is 5.5A.

By simply adding the max outputs of each of the ports: 2.4 2.1 1.0 = 5.5A. You end up with the Max Output of the power bank.

Input Charging:

The recharging of this power bank is going to take some time because it only uses a single Micro-USB Input port that has a recharge speed of 5V/2.0A and if you’re using a 2 Amp USB wall charger or higher, then a max recharge will take about 8-10 hours.

Similar Power Bank

The power bank is quite large and heavy but it’s manageable. Sure, it’s not going to fit into a but it can still be taken anywhere that you want to.

It has a length of 6.5 inches, a width of 2.8 inches and a thickness of 0.7 inches. The weight of the power bank is 14.8 ounces. So most of the time you’re going to be setting it down and charging your devices.

Functional Components:

All 3 of the USB ports can be found on the short side of the power bank, the Micro-USB Input port, and a LED flashlight.

On top of the power button is where you can find the power button and also an LCD screen. The LCD screen tells you how much power capacity is left in a percentage manner also which port you’re using with its Output being lit up on the screen.

You must press the power button for charging to begin.

Structure and Material:

The structure of the power bank is made of ABSPC so it’s quite sturdy and won’t fall apart.


On the tech side, the power bank does a great job with not heating up even when you’re using all 3 of the USB ports at the same time and its LCD screen works flawlessly everytime it’s used.


On the reliability side, the power bank does a great job. That’s because when you put all of its pieces together the LQQB Storage power bank packs a punch with its power capacity and its charging speeds.

The use of an LCD screen is very useful for telling power capacity and also for charging speeds too.

Similar Power Bank

The power capacity is able to change lots of device to full power multiple times over. Charging speeds are quite fast too with the power bank having a high Max Output of 5.5A.

juice-up, 120w, powerbank, wireless, 24000mah, um1106


It’s a large power bank that has a heavyweight. It’s not going to fit into a but it can still go anywhere with you. The use of an LCD screen is highly convenient.


It has a solid build quality to it with its use of ABSPC.


The culmination of its parts is what makes this power bank so reliable to use because it has a high power capacity, fast charging speeds and its use of a useful LCD screen.

Specs of the LQQB Storage 24,000mAh Power Bank:

  • Input: 5V/2.0A Via Micro-USB Input
  • LED Power Indicators: LCD Power Capacity Display
  • Size: 6.5 x 2.8 x 0.7 inches
  • Weight: 14.8 Ounces


The LQQB Storage power bank has all the right parts that make it a worthy competitor for top leading brands but there are a few areas that it could still work on; such as having all the ports share the same Max Output so none of the ports are limited to a set amount of power.

With that said, it still delivers a powerful charging experience.

WBPINE 24000mAh Solar Power Bank Review

The WBPINE 24000mAh Solar Power Bank Review is an all-around superstar when it comes to battery life, solar charging ability, and portability all rolled into one relatively small package.

WBPINE 24000mAh Solar Power Bank

We purchased the WBPINE 24000mAh Solar Power Bank so our expert reviewer could thoroughly test and assess it. Keep reading for our full product review.

If you’re in the market for a portable solar power bank, then you want to find a device that maximizes power and efficiency. The two main factors are the battery size and the number and wattage of the solar panels. There are single-panel solar power banks with large batteries or even power banks with up to five solar panels that FOCUS on solar energy conversion.

The WBPINE 24000mAh offers an attractive blend of battery and solar power. You get a massive battery, three capable solar panels, and a portable and durable design that makes this device great for extended outdoor use.

Design: Attractive but with a few quirks

Weighing in at one pound, this solar power bank is definitely a little hefty. But that’s not a surprise given the massive 24000mAh lithium polymer battery. It resembles a smartphone in shape and dimensions, but because of the large battery and the two solar panels that fold out, the size is more comparable to three smartphones stacked on top of each other.

Stowing the panels for travel is easy. Simply fold them in and secure them with the convenient snap closure, sort of like a wallet. The manufacturer also supplies a carabiner that you can hook to the leather loop attached to the clasping mechanism. (With the carabiner attached, clasping the device together is a little more difficult.) Also, because of the weight of the product, we did find that the snap can easily come undone or get twisted up with motion.

The WBPINE 24000mAh offers an attractive blend of battery and solar power.

We did not carry it around with the solar panels unfolded, but if you have a larger pack, we think this is definitely a comfortable option. And because of the heavy-duty plastic and faux-leather materials, it definitely stands up to some jostling. We knocked it around a bit on rocks and grass and found it to be quite durable.

There’s a great built-in LED flashlight on the back of the device with three light modes: steady, SOS, and strobe. Operating this light is not as straightforward as pressing the button, which is another design hiccup we noticed—instead, you have to press and hold the power button for a second or two and then press it again to cycle through the other modes.

At the same end as the flashlight, you’ll find two USB 2.0 ports and one micro-USB port. They’re all protected by a cover that locks into place to keep out water and debris.

The power indicator panel is located around the corner from the USB ports. The green light means it’s picking up a charge, and the other four indicators (each representing 25% battery capacity) flash blue when charging or in need of a charge, or solid blue when powered. Because this panel is small and on the side of the device, it’s not as easy to read the charge level—but that’s probably not a huge concern when in motion.

The WBPINE 24000mAh features an Intelligent Protection System to keep the device safe from short-circuiting, but there’s no waterproof rating. We found light rain didn’t impact it too much, but the manufacturer also recommends avoiding submerging the device in water. Based on our experience with the power bank in a few seconds of heavy rain, we recommend keeping it dry as much as you can, and would caution against exposure to water other than light rain.

Setup Process: A little lengthy but worth the wait

Out of the box, this solar power bank was about half charged. Though it’s possible to reach a full battery with a day or two of powerful sun, the manufacturer recommends plugging it in the first time for maximum charge capacity and for the best charging performance.

We followed the directions and plugged the device in to charge via the included micro-USB cord. The initial charge took seven hours.

After some use, we did test the WBPINE’s solar charging capacity. Stating with 0% charge, four hours in direct sun on a sunny day brought the device up to 25% (it did get very hot to the touch, however.)

Four hours in partial sun resulted in the same gain of about 25% charge. The manufacturer claims that it can fully charge over a 20- to 26-hour period. We experienced too much rainy weather to really be able to test that, but judging from just the more short-term tests we conducted, the solar charging function is one of the best aspects of this device.

Charging Speed: Fast and steady

After initially charging it on a power source, we maxed out the WBPINE solar power bank by testing out a few different devices including an iPhone 6S Plus, iPhone X, Kindle Fire, and Google Nexus 5X.

First, we gauged whether or not the charging speed was accurate. We took a reading of the device against each of these smartphones and tablets using a USB multimeter, which captured the voltage and amperage measurements. The manufacturer claims a charging speed of 5.V/2.1A, and that seemed to be pretty accurate.

The iPhone 6S Plus read at 5.04V/.89A and so did the Google Nexus 5X. The iPhone X came to 5.04V/.97A and the Kindle Fire’s charging speed read 5.02V/.96A.

Short bursts of sun can still do a lot to boost the battery.

In terms of actual charging time by device, the iPhone 6S Plus and iPhone X took about two hours, the Google Nexus 5X took just shy of three hours, and the Kindle Fire charged in four hours.

We also found the charging speed to be quite fast. In 30 minutes, the Kindle Fire went from 0% to 7% and the Google Nexus 5X reached 29%.

As for the average charging time of the WBPINE, we recharged it a total of three times and found the average complete charging time to be nine hours. That’s relatively slow, but the payoff is worth it since the battery will last for an impressive amount of time.

Battery Life: Head of the class

WBPINE claims that you could rely on this solar power bank for two weeks to charge cell phones. With adequate daily sun, this could probably very well be the case. Even our mix of sunny and cloudy weather over a week in the city showed that short bursts of sun can still do a lot to boost the battery.

On a single charge, we found that we could fully charge two phones, an Android tablet, and simultaneously bring up a phone from 0%-90% while also streaming media for three hours.

We also tested the battery capacity by attaching a drained Kindle Fire to the WBPINE and streaming YouTube videos until the charger ran out of juice. We found that we could easily rely on this power bank for nearly 11 hours of continuous use.

Price: A little pricey, but it depends on what you’re looking for

The WBPINE 24000mAh Solar Power Bank retails for 44.99, which isn’t bad considering the enormous battery. But there are options that offer a slightly larger battery for less, although with fewer solar panels. Others come with additional features like Qi wireless charging and a slightly larger battery for just a few dollars more. But if you want the battery and solar conversion power the WBPINE 24000mAh offers, we’d say this power bank is worth the price.

Competition: Weighing solar and battery power

The Hiluckey 25000mAh Solar Charger is nearly a carbon copy of the WBPINE 24000mAH, except for a couple of big differences. The Hiluckey offers 1000mAh more in battery power and an extra solar panel for a few dollars more than the WBPINE. While this option does offer more solar power wattage, it also adds on more weight, which can be a drawback if you’re trying to keep your pack as light as possible.

Then there’s the Elzle 20000mAh Wireless Solar Charger, which offers a Qi Wireless charging bank in addition to three solar panels and a 20000mAh battery. For about the same price as the WBPINE, the Elzle offers two USB inputs plus wireless charging capabilities, which would allow you to charge a Qi-enabled smartphone and two other devices. It does have a smaller battery capacity, though, so if you don’t need the wireless charging ability, the WBPINE is the better option.

Provides stellar battery power and effective supplementary solar charging—a great charger for a trip off the grid.

Its durability leaves something to be desired (don’t leave it outside in any heavy rain), but for the average adventurer, the WBPINE 24000mAh will likely fit the bill as a charging source for smartphones and tablets on your next adventure off the beaten path.
