Huawei 12000 40W SuperCharge Power Bank Review. Sleek, versatile, safe!

Yes, there’s a lot of affordable power banks in the market with at least 5V/2.1A of speedy charging tech. You can even get some Qualcomm Quick Charge ready power banks in the under PHP 2K range nowadays. However, most of them are not like this Huawei power bank.

Why? It is one of the very few in the world with Huawei-certified 40W SuperCharge charging solution. Meet the Huawei 12000 40W SuperCharge Power Bank. At PHP 3,990, it may sound expensive for a power bank with 12,000mAh of battery capacity.

But if it could really charge your Mate 20 Pro, Porsche Design Mate, and P30 Pro as fast as its 40W power brick on-the-go, it could be worth your hard-earned cash.


The power bank arrived in a familiar white box with some of the important details about the item.

Everything inside

Inside, you will see the power bank itself immediately followed by the short USB-A to USB-C cable and the paper documents. There’s no case or pouch included inside to protect the power bank. For a premium device like this, it would have been better if there’s a case included. Sadly, unlike the similarly priced wireless charger, it has no SuperCharge power brick inside. The SuperCharge USB Type-C cable and adapter package is priced at PHP 699.

Build Quality/Design

Front and back

The power bank itself is made out of an all-plastic material with a ceramic-like finish. The unit I got is the white-colored version which is very stylish in my opinion. It is a bit prone to fingerprint smudges, but to my surprise, it is not prone to hairline scratches.
Huawei did a good job with its overall coating. I also like its finish and curves as it is very comfortable to hold. Plus, despite its large 12,000mAh battery capacity, the Huawei 12000 40W SuperCharge Power Bank is not that thick at 15.5 mm and large at 135.4 x 69 mm. In comparison, my Huawei P30 Pro is 158 x 73.4 big. So, it is smaller than most modern phones.

Top view

On top, it has the USB-A port, USB-C port, 4-LED indicator, and a power key.

Bottom view

Below, you will see the certifications and other technical details. There is just some heft in it like other big-battery power banks at 225.5 grams. That’s fine.


It can even charge the MateBook 13!

Now to the exciting part! Huawei 12000 40W SuperCharge Power Bank is a pretty feature-rich type of power bank.

It has 12,000mAh of juice in total with universal compatibility (adaptive charging) which works on most phones, tablets, a lot of USB-powered gadgets, and USB-C charging ready laptops. over, the type of battery that Huawei used is more premium than most budget power banks in the market today. It uses a Lithium Cobalt Oxide type of cells which is more durable, denser, and slimmer than traditional batteries. We can’t measure that now, but basically, Huawei said that it has a longer cycle life. In particular, it has the 40W SuperCharge, PD 3.0, QC 3.0, SCP, FCP, and 5V/2.4A charging supports. 40W is super fast and it is one of the fastest charging solutions in town today. I have two USB ports. There’s a USB-A for output only and a USB-C for input/output with PD 3.0 support. By default, SuperCharge works right off the bat for both the USB-A and USB-C ports on devices like the Huawei Mate 20 Pro and Huawei P30 Pro. It can charge those phones with a 4,200mAh battery to 70 percent in 30 minutes. Then, it will slow down a little for safer charging. From 0 to 100 percent, you will just need an hour to full charge the Huawei Mate 20 Pro and Huawei P30 Pro. Overall, it can charge the Mate 20 Pro and P30 Pro at 100 percent for almost 3 times. Interestingly, its fast charging mode also works with other devices that we have that have Qualcomm’s Quick Charge protocol. One good example is it can charge our Mi 9T in around 90 minutes. For other devices with proprietary charging like the OnePlus 30W Warp Charge 30 and the 45W SuperVOOC, do not expect it to be that fast. But, at least, it will still be faster than traditional power banks with 5V/2A support or slower. For laptops, we discovered that the super-fast charging doesn’t work by default using the USB-A port. Yes, it can charge the laptop, but it won’t be that fast. To enable the quick charge on the Matebook 13 and other laptops with USB PD 3.0 charging, all you need to do is use a separately sold USB-C to USB-C cable and plug it to the USB-C port of the laptop. It still won’t be that fast as versus the default chargers with a higher power of those laptops, but at least, it can light up your laptop when needed. Charging the power bank itself is also quite fast if you have the proprietary 40W power brick, charging is under 2 hours and 30 minutes. That’s super-fast for a 12,000mAh battery. Using the standard 10W charger, charging will be slower at around 5 hours and 30 to 45 minutes from 0 to 100 percent. Aside from the Lithium Cobalt Oxide battery type and time-saving fast-charging features, the other reason why this power bank is not as cheap versus other power banks with the same battery capacity is the safety features.

In particular, it has TÜV Rheinland certification for safety from Germany. Huawei also added a lot of protection standards such as charge low and high temperature, battery overcharge, charging overcurrent, discharge/high temperature, Type-C port overheat, battery overdischarge, discharge overcurrent, battery short-circuit, charging overvoltage protection, charging undervoltage, output overcurrent, output undervoltage, and output short-circuit. In our experience, it doesn’t get hot all. It gets a little warm, but just a little, not hot.

Pros. Slim design with a sleek profile, premium 12,000mAh LiCoO 2 type of battery, fast and versatile charging, a lot of safety features Cons. No SuperCharge power brick included in the package, no flashlight mode, maybe the price

FlexSolar 40W Foldable Solar Panel with USB-C PD Review

Solar panels have improved over the years, and this has caused there to be many types of solar panels that have varying sizes, wattage output, charging ports, and of course, price ranges. So you don’t have to purchase a 100W solar panel if you don’t want one, as those can be quite expensive. Instead, if you want a personal solar panel that can charge small devices such as your phone or tablets and even a power station, you may want to consider lower-wattage solar panels.

In this review, I’m looking at this FlexSolar 40W solar panel. Yes, this is a 40W solar panel, so it’s inexpensive, and in my testing, I found this useful for charging personal devices. Let’s take a closer look.

Output Charging

There are three ways to use this FlexSolar 40W solar panel: the DC 5521 port, USB-A, and USB-C Power Delivery port. The DC 5521 port and the USB-C Port can output 40W. The USB-A port features Quick Charge, which means that it’s able to output 18W and can fast charge most Android phones.

When using any solar panel, you have to ensure that the solar panels are getting optimal sunlight; if they’re not, then the charging power you receive from the panel will not be very good. The same is true here. When completely unfolded, this FlexSolar 40W solar panel has six panels that can receive sunlight. What I found most helpful was placing the panels at an angle; in my case, I just used two chairs, which worked well. Most solar panels have a kickstand at the back to be placed at an angle, but these don’t.

In my testing, while the panels were receiving nearly full sun exposure, I began by charging a Samsung Galaxy Note 9, and the Note 9 was able to fast charge from the USB-C Power Delivery port. I charged my Lenovo laptop from the USB-C PD port for my test, which could charge at about 8W. So the charging speed for the laptop was relatively slow, but it’s still able to charge it, so if you don’t have any other way to recharge your laptop, this solar panel can do an alright job if you have long enough sun exposure on the panels.

I charged a VigorPool Lake 300 power station for my next test via the USB-C PD port, which could charge at about 20W to 25W.

Overall, I recommend using this FlexSolar 40W solar panel to charge small devices such as phones, tablets, and laptops. Charging devices such as power stations can be useful, too, that said, the charging speed may be too slow for what you’re getting, and a higher-wattage solar panel will service you better.

power, bank

Size and Weight

When the solar panel is folded, it has an 11.1 inch width, a length of 8 inches, and a 1.8-inch thickness. When the panel is unfolded, it has a length of 48 inches. So it’s pretty long when fully unfolded. The panel weighs 2.8 pounds. So this panel could easily be taken hiking and camping because it is just that small and lightweight.

On the functional side of it, the solar panel is just like any other one; make sure that the panels are receiving direct sunlight and the ports are ready to use. Where the ports are located, you’ll find a red light that turns on to show that the ports are being powered.

Included in the box are carabiners that can be used to hook onto the panels, and then you can hook the panels onto your backpack or wherever else that makes it convenient for the panel to receive sunlight.


The build quality of this Solar panel is good, and it felt solid to me. The panels are made of monocrystalline and have an IP67 water resistance. That said, I’d consider the panels to have IP67 water resistance, meaning that they can withstand rain with no problem, but the charging ports are not water resistant, so you should keep them away from water.


The most reliable way to use this 40W solar panel is to charge phones and tablets. If it’s your last resort, this panel can also charge a laptop, as I could charge my Lenovo laptop. This isn’t meant for recharging power stations, as most have a higher solar input than 40W, but it can be done.

Best Portable Chargers for Huawei P and Mate Series Phones

A portable charger (aka power bank) can mean the difference between stressing over your Huawei’s battery life. Or being able to use it all day long without worry. The best portable chargers for Huawei P and Mate phones can all fast charge them from 0-50% in 30 minutes. Or even faster if they support SuperCharge. While also offering enough capacity to keep you going, whether for a busy workday or long trip.

Huawei SuperCharge 40W 12000

Fast Charging Huawei P40, P30, P20, Mate X, Mate 20, Mate 10

Huawei phones use two unique fast charging standards: SuperCharge and FCP.

Charging Speeds for Huawei Phones

SuperCharge increases both the voltage and the current going into the phone. Most other standards only increase the voltage. This allows Huawei to recharge their phones 20-40W. Much faster than the 18W we see on other standards. The downside is a lot of heat. So the power conversion circuits have to be in the charger. This keeps the phone from support other fast charging standards.

Different model Huawei phones have different SuperCharge wattage limits. The flagship phones (P series Pro) go up to 40W. The rest is around 20W.

FCP was Huawei’s first fast-charging standard for their early USB-C phones. It only offers up to 18W, like USB PD and Quick Charge. But newer Huawei phones continue to support this standard. And it is available from third-party chargers.

All the non-Huawei chargers listed below will be supporting FCP.

USB-C to USB-C Cable

An FCP charger uses a USB-C to USB-C cable to connect to your phone. You can use the cable Huawei included. But for a second charger, you likely want a second cable for convenience.

If buying a SuperCharge charger you will need a USB-C cable which supports 5A (100W). As such chargers tend to use USB-A to USB-C connections you’ll want to stick with official Huawei cables.

  • For a non-Huawei charger stick with USB-C to USB-C cables with 60W and USB 2.0 support.
  • For Huawei, SuperCharge uses its cable.

The best power banks 2022

Choosing a power bank can be a minefield. There are cheap ones, pricey ones, and sometimes you’re paying simply for a name – but there’s a lot more to finding the perfect portable charger than looking at price alone.

Some other things you might consider include speed, both in charging your connected device and recharging the bank when it empties. Capacity is important, too: it needs to be high enough to get your through the day with juice to spare – even share – without weighing down your or bag.

Ports and connections matter, too. What are you charging? A phone, a laptop, a watch? The number and range of ports is important, and if you want to avoid carrying multiple cables then you could look for a version with built-in cables or wireless charging.

While we care about design, it’s actually much lower on our priority list than the things we mention above – unless, of course, we have need for a particularly rugged model or something that supports solar charging because we’re going to be away from mains power for an extended period. That’s not to say we won’t appreciate added extras such as an LCD screen and waterproofing – don’t you want the coolest and most convenient power bank you can get for your money?

Best power bank reviews

Zendure SuperMini X3 – Best 10000mAh Power Bank

The Zendure SuperMini X3 certainly isn’t the cheapest 10000mAh power bank around, but it makes up for that in specs.

The headline is the 45W USB-C PD charging – for both input and output. That means you can re-charge the power bank itself in just an hour or so, but also that this is fast enough to meet the max charging speeds on most Apple and Samsung phones, and can even keep many laptops running.

The same port also supports the PPS standard at up to 33W speeds.

There are also two USB-A ports, one at 18W and another at 15W, and you can use all three ports simultaneously with 15W speeds from each.

Throw in the small LCD display to report battery life and the light and compact design (in a range of four colours, no less) and it’s easy to see why you might want to spend a little extra for the SuperMini X3.

Charmast 10,400mAh Power Bank – Best Value Power Bank with LCD

There was a time when power banks with LCD displays were rather expensive, but have now come down as the screens filter through to even affordable models like this.

The power bank also has three outputs, which will come in handy if you have multiple devices to charge. There are two full-size USBs, plus a USB-C PD port that can act as both input and output, and all three support 18W Quick Charge – although only one at a time.

On the side is an additional Quick Charge 2.0-compatible Micro-USB, which can also be used for charging the bank. It will charge in about 3.5 hours with a Quick Charge/PD adapter, but about 5.5 hours with a standard 10W charger.

The downside of the design is that it’s a bit bigger than many of the super-slim, similar-capacity models on the market. This Charmast is roughly the same width as a phone, but a little shorter and a fair bit chunkier. It weighs in at 228g, which you may decide is better suited to a bag than your

Charmast supplies a soft mesh carry case and a short USB-A to USB-C cable in the box, a nice touch.

Zendure SuperMini Go

  • Interesting camera-inspired design
  • Supports 15W wireless charging
  • Strong device support
  • Available only via IndieGoGo (for now)
  • LCD is a little dim and can be difficult to read

The Zendure SuperMini Go is something a little different: a power bank that tries very hard not to look like one.

Zendure’s design is inspired by classic cameras, which is if nothing else a fun way to incorporate the large ring required for wireless charging – which here sits right where a camera lens would be. Instead of a viewfinder, there’s a rear LCD display to show battery percentage – though be warned that this is quite dim and hard to read.

It’s available in silver and black finishes, along with our more out there ‘Sunset Cyan’ gradient.

The SuperMini Go isn’t all about looks though, and it has some solid specs to match. The total capacity is 10,000mAh, and in addition to 15W wireless charging (with a magnet to keep phones steady) there’s 20W USB-C charging and 22.5W USB-A charging.

Compatibility is impressive too – not only will this work with both iOS and Android devices, but the ‘X-Charge’ mode is capable of topping up lower power devices like wearables and headphones, which not all power banks support.

The SuperMini Go is available now for backers on IndieGoGo with discounted launch pricing from 44 (down from an official price of 69), but with Zendure’s track record it’s very likely this will be in stores including Amazon before long.

JIGA 30,000mAh Power Bank – Most Versatile Power Bank

JIGA is a new name to us in terms of power bank tech, but its 30,000mAh power bank is interesting for a number of reasons – and not least the huge capacity, which will be some comfort on trips away from mains power.

While it’s something of a throwback to power banks from a couple of years back, with its built-in LED flash (certainly useful for camping trips) and durable but plasticky design, it also takes us back to the days where you didn’t have to sacrifice ports for portability.

It’s surprisingly small for such a high-capacity bank, but it’s more bag- rather than.friendly.

The JIGA has USB-C, Micro-USB and Lightning inputs, allowing you to fill its battery using whatever cable you have to hand. It’s a shame that the USB-C port doesn’t also work as an output, but there are three full-size USB-A outputs, each rated at 10.5W.

This isn’t the Power Delivery speeds we’re becoming increasingly familiar with today, but it’s plenty fast for charging a phone (or multiple phones).

If all you need is a healthy stream of power to keep topped up a number of mobile devices, this JIGA power bank will be a very handy device to have around.

Anker PowerCore Essential 20,000 PD – Best 20,000mAh Power Bank

Hailing from Anker, a respected brand in the power bank market, this 20,000mAh portable charger represents very good value at this capacity.

The 345.5G Essential is a black plastic brick, though relatively compact for the amount of power it can hold. It has a textured top surface that improves grip in the hand, as well as the overall appearance.

We’re pleased to find support for Power Delivery, but do note that it’s only up to 18W, and therefore not likely to be sufficient to charge a USB-C laptop. Still, for quick-charging a phone or tablet, this is a useful device.

A full-size USB output that uses Anker’s PowerIQ smarter charging algorithm is joined by a USB-C port that is both input and output. On top is a power button with four integrated LEDs that reveal remaining capacity, and you can use this to enter a trickle-charging mode suitable for smartwatches and earbuds.

A USB-C to USB-C cable and soft mesh carry case are provided in the box, which is a nice touch.

Anker PowerCore III 10K Wireless – Best Wireless Power Bank

The Anker PowerCore III 10K Wireless is a Qi wireless charger with a special feature: you can use it as a portable power bank, too, which can be super handy.

You can use it at home or work plugged in, and carry it around with you for wired or wireless charging when you are away from a power socket. Because it’s wireless, there’s no need to carry a cable around with you.

As the name suggests, the PowerCore III 10K has a decent sized 10,000mAh battery, which should offer at least three charges from the power bank before it needs recharging itself.

The wireless charger is rated at 10W. Place your device on the centre of the circle. We didn’t find the placement too sensitive, as some wireless chargers can be. It’s not auto-start, though – as a power bank it requires you to push the button first.

You can also charge from the two USB-A ports at one end – at a total of 18W, so charging two or three (one wireless, two wired) devices will split that power output.

Anker PowerCore Magnetic 5K – Best MagSafe Power Bank

This portable wireless charger is one of the best accessories you can get for your iPhone.

power, bank

In essence, it’s a 5,000mAh palm-sized power bank that will charge your compatible iPhone simply by snapping it onto the back with MagSafe.

It works through some cases, charges over USB-C, comes in a range of colours and, even if you don’t have MagSafe, can be used to charge almost anything via cable.

A handy set of LEDs indicates how much charge the PowerCore has remaining.

Moshi IonGo 5K Duo – Best Design

It’s expensive, but you’ll pay out for the IonGo 5K Duo from Moshi if style is as important to you as is functionality.

Almost identical in design to the IonGo 5K before it, but here with both USB-C and Lightning cables built-in (hence the name Duo), the Moshi is an undeniably cool-looking power bank that comes tucked away inside a vegan-friendly soft leather case with a magnetic clasp and an anodised aluminium faceplate.

The additional cable means it’s now suited to Android as well as iPhone users, although as before this is Made For iPhone-certified.

This is a truly premium device with a colossal 10-year warranty going a long way to account for its higher asking price. It’s also possibly the dinkiest 5,000mAh power bank we’ve seen, suggesting there are some serious high-tech components inside.

At this capacity, expect a full charge for any Android phone, and potentially two for iPhone. Moshi claims the bank will also retain that power for up to 27 months when left unused.

Charging is up to 15W over USB-C and 12W over Lightning. Use Lightning and USB-C together and you’ll see slightly slower charging speeds, with a max total output of 3.4A (17W).

You can also use the USB-C cable for recharging the bank, again up to 15W. Better still, the Moshi supports passthrough charging, allowing you to charge both it and a connected device at once, but given that there’s no separate input here that’s going to work only with iPhone.

The Duo is currently out of stock at Amazon, but you can still pick up the iPhone model.

Chargeasap Flash Pro / Flash Pro Plus – Fastest Charging Power Bank

  • Unbeatable recharging speed
  • High-capacity (25,000mAh)
  • Range of outputs
  • 5-year lifespan
  • Expensive
  • Bulky and heavy
  • Attracts fingerprints
  • No charger or cable supplied

These graphene-composite power banks are able to charge cooler than ordinary lithium-polymer batteries, and thus can do significantly faster: you’ll get to 80% of these 25,000mAh batteries in just 45 minutes.

In addition to this there is a healthy smattering of ports, with three USB-Cs running at 100W, 60W and 20W, a 50W USB-A that supports Quick Charge 3.0 and SVOOC, plus wireless charging. You get a 15W MagSafe pad and a 5W Apple Watch charger in the Flash Pro Plus, and a 15W Qi charger in the Flash Pro.

Down sides include an expensive price tag, and a bulky, heavy design, but for sheer performance and functionality the Chargeasap banks are among the most capable we’ve ever tested.


What capacity power bank do I need?

Don’t fall into the trap of thinking a 3,000mAh power bank will give your 3,000mAh battery smartphone a full charge, and that a 9,000mAh power bank will charge it three times. No portable charger runs at 100% efficiency. In truth, most average between 60- and 70%, with the best-performing models able to reach 80- or 90%. Wireless charging models may be less efficient still.

To work out what capacity bank you need, first check the spec of the device you want to charge to find out its battery capacity, then decide how many times you want to be able to charge it. For a rough estimate, calculate Connected device battery capacity x Number of recharges x 1.6 = Minimum power bank capacity you should look to buy.

As a rule of thumb, a 5,000mAh bank is a single-charge device, 10,000mAh hits the sweet spot between capacity and portability, and you want to look for closer to 20,000mAh for a laptop. We’ve got some of those high-capacity power banks here – just don’t try to stuff any of them in your !

How long does it take to recharge a power bank?

The time required to recharge a power bank will depend on its capacity, what you are using to recharge its battery and whether or not it’s empty.

For the fastest charging you should look to the new breed of power banks that support graphene technology and charge over a DC input (such as the Chargeasap Flash Pro – a 25,000mAh bank that can get to 80% in 45 mins and 100% in 70 mins), but these tend to be pricey.

For mainstream power banks, the fastest you’ll find is a USB-C inout/output that supports Power Delivery. This standard now goes up to a maximum of 240W, but in portable chargers you should expect to find an 18W port. Using such a port, the average 10,000mAh power bank might recharge in 2-3 hours from empty.

The cheapest models still tend to charge over Micro-USB, usually at around 10-12W. Avoid 5W power banks like the plague unless they are very low in capacity or you’re not in a rush.

What is passthrough charging?

Passthrough charging allows you to simultaneously charge devices connected to a power bank and the power bank itself. It’s a very handy solution if you are short on mains power outlets and need to get multiple devices charged up overnight, for example. However, not all power banks support it, so be sure to check the spec of your portable charger before you buy.

How do I know how much power is left in my power bank?

Assuming you know how much capacity it had when full, you can work out how much power remains either through a series of LEDs on the casing (usually activated by plugging in a device to charge or pressing a button on the side), or via the LCD if your power bank supports one. LCDs are preferrable, because they give a more accurate readout, particularly when it comes to higher-capacity power banks.

What are GaN power banks?

GaN is short for gallium nitride. It requires fewer components than traditional silicone chargers, which means power banks that use the technology can be less bulky and more efficient. If portability is your primary concern, then as well as considering the power bank’s capacity you should also look for one that uses GaN.

What charging speed should I look for in a power bank?

The first power banks on to the market ran at 5W, which is the same speed as the original iPhone chargers (aka slllllloooooowwwww). We wouldn’t recommend anything below 10W these days. This speed is known as ‘fast charging’, and it’s still rather common in cheaper models, but it’s not really the fast charging we’ve become accustomed to today. So many of the latest smartphones now support super-fast wired charging, and it seems crazy not to buy a portable charger that supports that top speed if possible.

The standard your phone uses to achieve its top charging speeds is important here. Some have proprietary technologies that work only with accessories manufactured and sold by that company. Some offer fast charging through Quick Charge or Power Delivery. Some support neither Quick Charge nor Power Delivery, but do support protocols such as PPS (Programmable Power Supply) or SCP (Super Charge Protocol). Make sure the portable charger you buy matches the fast charging standard supported by your phone.

The term Power Delivery does not in itself denote a performance rating. It could be capable of delivering anything between 18W and 240W. This is particularly important if you’re looking to charge a USB-C laptop – anything under 30W won’t cut it, many laptops will refuse to play ball below 45W or even 60W, and some larger laptops might require 90W. You will need to check the spec of your laptop to know what speed it requires.

At the other end of the scale, if you need to charge a low-power device such as a smartwatch or a pair of wireless earbuds, look out for a power bank that is certified for low-power devices. Many of those that are not will simply cut out when you try to charge these devices, because they aren’t able to detect a significant drain on the battery.

Power bank manufacturers rarely provide the speed of their outputs in watts. Instead you’ll see a rating in amps, which you multiply by the voltage rating (usually five) to get the rating in watts. So 2A x 5V = 10W.

What is Power Delivery?

USB-C and USB PD are often confused, but the important thing to remember is that USB-C is a reversible connection type, while USB PD is a power delivery specification, overseen by the USB Implementers Forum (USB-IF) and often expressed simply as ‘PD’. With version 3.1 of the specification, Power Delivery is able to carry up to 240W of power plus data over USB-C (previously limited to 100W), but devices that support Power Delivery can range from 18W right up to 240W.

What is Quick Charge?

Quick Charge is a Qualcomm fast-charging protocol that runs on the Snapdragon processors we see inside many smartphones, hence it has become commonplace in the mobile market.

power, bank

The latest version is Quick Charge 5, which operates at up to 100W and supports USB PD PPS. However, while they are often seen together, Quick Charge and Power Delivery are not the same thing.

Quick Charge 5 is a massive jump up from Quick Charge 4/4, more efficient and able to run cooler and safer, and Qualcomm says it can get a device to 50% in just 5 mins. It is backwards-compatible with earlier versions of the protocol, including 18W Quick Charge 2/3, which are still very common in power banks.

Which outputs should I look for in a power bank?

The type and number of outputs you will need on a power bank depends entirely on what device or devices you want to charge. Pretty much all power banks have a full-size USB output that you can use to plug in your own cable, but it’s not always going to be the fastest way to deliver a charge to your device. You’ll also find USB-C and Lightning outputs, magnetic wireless charging pads and AC outlets if you shop around. Some power banks even have built-in cables to stop you needing to carry around your own, though you will still need one handy to recharge the power bank itself.

Why is the maximum output of a power bank important?

Some power banks have multiple outputs for charging your connected devices, but few power banks are able to simultaneously support all of them at the top advertised speed. Watch out for those that have a lower maximum output than the sum of all ports together. Also be wary of those that have multiple outputs but a very low capacity – these aren’t really designed for plugging in multiple devices, only to be versatile.

What happens when my power bank is more powerful than my connected device?

There is no need to worry about plugging devices into ports that are capable of delivering more power than the device is able to accept, since USB devices will draw only the power they need. Many power banks include technology that is able to intelligently dole out this power among ports more appropriately, depending on what devices you are attempting to charge (often known as Power IQ or similar).

Can I take a power bank on a plane?

Yes, but it must be in your hand luggage, and if it is higher in capacity than 27,000mAh (100Wh) you will need to check with the airline before flying. Make sure you take it out your bag as you pass through security. If a power bank is damaged then it will not be allowed on the plane as it could become a safety hazard. You should also ensure the specifications are clearly printed on the side of its case, as is the norm.
