Need help choosing a high capacity power bank 20000mAh or over?

If you are looking to buy a high capacity portable battery charger but are unsure of which specifications or features are important here’s some info that may be of help.

Capacity – Measured in mAh’s (milliampere-hour) is basically the amount of storage the power bank has. This amount is just a guide, the actual amount the battery delivers is dependent on its efficiency. This can be anywhere from 70%-85%. If you are charging a phone with a battery size of 2000mAh with a 20000mAh power bank, you’d get 10 full charges if it was 100% efficient (this will never happen). In reality, you are far more likely to get 7-8 charges.
Max Output – This refers to the overall output of the power bank. Typically more important on a high capacity portable charger, when recharging multiple devices at the same time. If your Smartphone requires 1A and your tablet requires 2.1A then a power bank with a 3.1A Max output would be sufficient. If you were then to plug in the third device, the 3.1A would be shared, and the recharge time would take longer.
Safety Systems – Most, if not all power banks will offer protection against short-circuits, over-current and overloads. Usually, the power bank will shut off and will require you to connect the charging cable to reset the system.
Pass-through charge technology – This allows you to plug devices into the power bank as it’s being recharged. On high capacity power banks, this feature is extremely useful and not often seen.
Additional Technology – Each power bank will have its own terminology, Anker calls theirs ‘PowerIQ‘, RAVPower use the name ‘iSmart‘, Zendure has ‘Zen‘ and the list goes on. There are some variables depending on the manufacturer, but in general, this relates to an adaptable output from each USB port. When you plug in a device, the power bank will identify it’s maximum recharge speed and deliver the correct amount of power.
Battery Quality – This is something that you will need to consider. It’s hard to know about the quality of the Lithium battery inside without cracking the power bank open and having a look (not advisable). Generally speaking, if it’s ridiculously cheap it will likely be of poor quality. My advice is to choose a recognised brand that has some control over its own RD. There are so many companies attaching brand names on generic OEM power banks and selling them cheaply. Portable charging devices like the Zendure A-Series power bank do cost more, but it’s for a good reason. – back to the list

i wish you would talk more about the Nut Volts of these particularly what batteries they use the Ravopower and Anker both use brank name LG/Panasonic cells (18650) they are on the top of their game for size and capacity please report what Zendure EasyAcc Tronsmart use for batteries

Please check out the ZMI 20,000 mAh power bank – PowerPack Aura. Similar specs with 27W USB-C PD fast charging but only 35.99.

I got the Zendure A8 20000mah powerbank before it was upgraded to have Quick Charge 3.0, I really want to upgrade, but my current one works so well! Maybe I can give it away as a Christmas present and treat myself to the new one

Best “rugged” power bank suggestion? Price not a major concern but a couple options are appreciated. Will be used in cold / wet / camping / backpacking conditions.

Hi Josh, if you’re looking for a high capacity rugged power bank, I’d check out the EasyAcc one, here’s a link EasyAcc make really good quality power banks at a respectable price. Hope that helps Simon

I bought the Zendure A8 power bank years ago before it updated its feature to include Quick Charge 3.0 I have an S7 Edge and my wife has an S8, I’m so tempted to splash out on an upgrade. Do you know how much faster the new Zendure A8 will charge compared to the original power bank?

Did anyone notice that only Zendure A8 has a digital display that accurately tells you exactly how much power it has left? That feature is awesome. Zendure A8 is also the only one that has pass-through charging. It also has the highest output: 6.1Amps!

You’re quite right Teddy, the Zendure A8 got a serious upgrade recently. It’s definitely going to be higher up the list, I’m just waiting for a review unit to arrive.

So pleased to see the Zendure A8 portable high capacity power bank got the Quick Charge 3.0 update, I love the original design of the power bank, but I really wanted a QC 3.0 compatible charger for my HTC 10 phone.

It’s a great power bank, a little more pricey than some of the others, but it’s built like a tank and does look great, thanks for the comment.

Took your advice and bought the Ravpower 22000mah power bank, it arrived the next day (fully charged) and works like a absolute dream! Thank you!

You’re welcome, I’m currently using the RavPower Quick Charge 3.0 charger as my main high capacity power bank, but the 22000mAh is just as good, just takes a little longer to recharge.

Dear simon. Tha’ks for this brillant article. So usuful and clear! I was wondering though, how do i determin the output (or input? Not sure) my Sony z5 xperia compact needs? And my Galaxy tab 4? Where do i find this information in order to know what lax output i should be fine with… Thanks a lot!

Hi Jack, I believe the Sony Z5 has a 1.5A input and the Galaxy 4 would probably need a bit more. I wouldn’t be concerned about using any of the power banks on this list for either device. It’s actually the Phone or Tablet that’s drawing the charge rather than the power bank pushing it out if that makes sense? If you had a device that only required 0.5A plugged into a 2.4A output of a Power Bank, that’s all it would draw, the other 1.9A is redundant. Hope that helps and thanks for the feedback.

Thanks, Andy! After reviewing so many high capacity power banks over the last few years, I think I’ve done the legwork required to make a useful and accurate list on the subject. I’m also looking into buying some accurate testing equipment to get some numbers on the actual efficiency rates of each of the power banks.

I visited quite a few sites today in search of buying advice regarding power banks. Your site was by far the best. Your research was thorough and concise and eliminated lots of the “junk” that other sites waste time on. As a result, I was able to find just the right power bank for my needs. Many thanks for your excellent recommendations. I also appreciated your explanation on the specs of power banks and the importance of each one relative to user needs.

Roy, Really appreciate the positive feedback, I’m amazed how little effort some of the more ‘well-established’ review sites make these days, especially when it comes to power bank reviews.

I bought the ravpower quick charge 3.0 power bank, I think my phone has Qualcomm 2.0 will this effect the speed?

Qualcomm Quick Charge technology is fully backward compatible, so if your phone has QC 2.0, a Quick Charge 3.0 power bank will provide a QC 2.0 equivalent fast charge – hope that helps.

Anyone with a Quick Charge compatible phone should definetly opt for a power bank with Quick Charge technology, it makes a huge difference. You should feature more high capacity power banks with QC 2.0 and 3.0.

Hi Techman, thanks for the feedback! Rather than swarm the top of the list with Quick charge 3.0 power banks, I’ve added some alternative options to the RAVPower QC 3.0 charger. I do agree with you that it makes a massive difference to recharge times, but that’s only if you have the Quick Charge wall adapter too. Anker have just started selling their quick charge power bank with an included QC3.0 wall charger, seems like a sensible thing for the others to do as well.

The RAVpower 26800mAH power bank should be top of the list IMHO, max amps is worth more that pass through charging

They’ve actually just launched a new power bank with even more Max Output. Their 22000mAh portable charger has 5.8A – I’ve given it the top spot on the list.

To get a good quality 20000mAh high capacity power bank for under 40 is a bargain, but considering the EasyAcc Monster has the double charging inputs, it’s seriously good value for money.

best, 20000mah, power, bank, reviews, portable

I was planning on buying the Zendure A8, seems like they are only currently offering the Zendure A3 or A4 in the UK, shame because I really like the design

You may be able to buy the Zendure A8 from the US Amazon site at a cheaper price, which may compensate for the additional cost for the international postage? Worth a try, it’s a great Power Bank.

Thanks for the list, I’d have rated the RAVPower 26800mAh Power Bank higher, it’s got the biggest max output of them all, by far. For me, I often need to recharge 2 tablets at a time and a phone. The RAVPower Power Bank is the only one the this whole entire list with enough output to manage that without trickle charging them.

Hi Terry, It is a great high capacity power bank, and really good value for money too – thanks for the comment.

Nice list, I was looking for an even larger power bank than 20000mAh, it seems like there are not that many decent ones to choose from, is there a reason for this? Thanks

Hi Ian, There are very few good power banks over 30000mAh. The only high capacity power banks I’ve seen above the 20000mAh bracket are poor quality and really cheap. The capacity can be a little deceiving sometimes, you will find some that suggest capacities of 50000mAh, but trust me, they are closer to 20000mAh. My advice would be to buy two good quality power banks with 20000mAh rather than a poor quality 40000mAh battery. That way you can recharge twice as quick.

The Zendure A8 does look really good, but it seems far more expenive than all the other battery packs on the list. The 20000mah LimeFuel Blast power bank seems much better value for money in my opinion. They both have pass-through charging and the LimeFuel has an extra 1A max output.

Hi Liam, the LimeFuel Blast is an awesome 20000mAh power bank and considerably cheaper than the Zendure A8. I do think the A8 has a far better build quality and some additional technology that sets it apart. It’s real important to have a Power bank that you can trust, the Zendure is so durable, they run it over with a car and it’s undamaged. The standby time on it is fantastic too, for a high capacity portable battery to still have 95% of it’s original charge after standing around for 6 months is pretty unique.

The EasyAcc 20000mAh power bank is just what I was looking for, I burn through portable batteries like mad with photography work. I currently use two 10000mAh battery packs, because there is enough time to charge each of them over night, A 20000mAh typically takes around 12 hours from a mains adapter. Having a double input it’s ideal, I’m surprised more high capacity power banks haven’t added the feature, is this the only one that has it?

Hi Pete, as far as I know this it is. This works great with a mains adpater with 2 or more USB inputs, that way you only need one power outlet.

Thanks for the guide, the whole mAh capacity thing was a little confusing. Why don’t they just label the power bank with the actual capacity after the loss of charge is account for?

Hi Bev, I think there are quite a few variables that will effect the efficiency. Some power banks may perform better than others, even if they are the same make and model. Even the cable itself and the device you are charging can effect it. All of the ones above perform at the top end of the scale, I’ve tested a few others that have struggled to achieve even 60% efficiency.

Hi Oscar, Thanks for your comment, I totally agree it’s an amazing portable power bank, an absolute beast. I have the Zendure A8 and the A2, they are both awesome, the A8 for it’s huge capacity and the A2 for it’s compact size, I can’t fault them.

I backed the Zendure Power Bank when it was being crowd funded, it’s an awesome charger. Very few have the ability to charge devices while also re-charging. This feature is amazing especially on a high capacity power bank. I plug my tablet into the Zendure and plug the Zendure into the adapter, once the iPad is fully charged the Zendure automatically stops feeding it juice and continues recharging itself until it’s also fully charged, then it shuts off the charge too.- Love it!

Does Flash use graphene batteries?

Flash, Chargeasap’s most powerful graphene power bank, integrates Panasonic graphene composite batteries. Panasonic stays at the forefront of battery technology, and its revolutionary batteries allow them to charge faster than ever before.

These batteries have been specially designed a pioneer in the electric vehicle space in partnership with Pansonic who is the manufacturer. Only recently launched in 2019 and still not widely available publicly, this battery is currently the highest energy density battery in the world. Our Flash graphene power bank is also the world’s most powerful 210W USB-C power bank with 20,000mAh capacity utilizing 4 x 21700 lithium polymer graphene composite battery cells.

What are the Graphene power banks?

Graphene power banks are essentially portable power banks enhanced with graphene batteries.

Graphene is the world’s most conductive material with ultra-high thermal conductivity, drastically increasing charging times. Instead of having to wait for hours for your device to charge, plugging into a graphene battery bank can take your device to full charge in just minutes. Our Flash graphene charger can have a full charge in just 1 hour and 10 minutes (20,000mAh) or 80% (16,000mAh) in only 35 minutes. making it 10 times faster than traditional portable power banks.

While traditional lithium-ion batteries are expected to last to up around 500 charge cycles, graphene-enhanced batteries triple this with an estimated 1500 charge cycles! Furthermore, a graphene battery’s lifetime is much longer than lithium-ion’s two to three-year lifespan.

Graphene batteries are an emerging technology. The material itself is a composition of carbon atoms tightly-bound in a honeycomb structure. It’s so lightweight, that this structure is a mere one atomic layer thick, essentially making graphene a 2D structure.

Due to the high production costs of graphene, power banks using graphene technology are relatively new and not widely mass-produced.

Do Graphene power banks charge fast?

Graphene offers higher electrical conductivity than that of lithium batteries. This means faster-charging cells that can deliver very high currents resulting in super-fast charging times.

Lithium-ion stores up to 180Wh of energy per kilogram while graphene can store up to 1,000Wh per kilogram. The ultra-fast charging times is one of the best and biggest aspects of graphene battery technology.

While there are technologies in place for fast-charging lithium-ion batteries, they still carry some limitations. Pumping in too much wattage could result in the battery breaking or even blowing up.

The difference with graphene battery power banks is that they can substantially shorten the charging time from zero to full. For example, a 3,000mAh lithium-ion battery can take up to 90 minutes to charge, while a graphene battery at the same capacity will charge in roughly a fourth of that time. Graphene is just better at handling higher wattages of electricity which sets them apart from lithium batteries.

What is a Graphene battery?

Graphene is a fantastic conductor of heat and electricity. Unlike lithium, that doesn’t fair as well when you put a lot of energy in or out of it, graphene is the world’s most conductive material. making it a game-changer for battery technology.

Graphene is very light, and even 5 sheets of it will only end up being 5 atoms thick. This means graphene batteries are exceptionally light and transportable. A perfect partner for portable power banks.

Graphene batteries are well-established and come in many forms. It can be used to power anything from watches to electric cars.

Are Graphene batteries the future?

These batteries are still relatively new and will take some time to become more widely available as the technology is still progressing. However, once they do, you can expect to see graphene batteries used in nearly all electrical appliances and devices.

In the future, graphene batteries should replace lithium-ion batteries. Big technology companies are aware of the limitations lithium has, and are already embracing ways they can begin manufacturing graphene batteries on a larger scale. For, not only are these batteries high-performing, but they’re also more environmentally-friendly than lithium-ion overall and can be much more easily recycled.

The biggest obstacle to overcome right now is the extremely high cost of manufacturing. However, as popularity and demand grow, production can become more refined and cost-effective. allowing the market to become more widely adaptable.

At this present time, one of the most viable ways to integrate graphene batteries into devices is by using it in conjunction with traditional lithium-ion batteries.

As such, major companies such as Tesla Motors, Samsung, and Microsoft are hinting at the development of next-generation graphene batteries that may lead us into the future advancement of battery technology.

With Chargeasap, you can get in on the action already with our existing graphene power banks set to change the way you charge!

How do Graphene power banks work?

Graphene power banks work in the same way as a traditional lithium-ion power bank, the difference is that with graphene-enhanced batteries. such as what’s used in the Chargeasap Flash. you will experience:

Larger battery capacity: with 5x the battery life of an iPhone 11
Faster charging: Single USB-C port supporting 100W USB-C Power Delivery for devices including MacBook 16⁣. Both additional USB-A ports support 18W QC3.0 and 40W Huawei Supercharge, Oppo Vivo Flash Charge⁣

When you first see the Omega 200W, you won’t believe that it actually delivers as much power as it does.

Cons

We’ve done tons of reviews on power banks on this site, and at this point, there’s likely a portable charger for every person’s needs. There are small ones that may not have a lot of power capacity but are incredible; some power banks feature fast charging. In contrast, others don’t, and others are brimming on becoming portable power stations simply because they have so much power.

We’re looking at this Baseus Blade 100W power bank in this review. This Baseus portable charger may be the only one you’ll ever need if you find its charging power enough for your needs, and we think you will after knowing what it’s capable of.

Power Capacity:

The power capacity of this Baseus Blade portable charger is 20,000mAh. Now there are a lot of power banks on the market that has higher capacities, but a 20,000mAh capacity is just enough to charge most portable devices. This power bank can charge up most phones to full power three times or more. Tablets and laptops with larger batteries will fair about a single full charge, and you’ll have some spare capacity to use later.

You’ll be able to depend on this power bank for more than a single day, and that’s a lot better than lower-capacity power banks that require a recharge after a single use.

Output Charging:

The charging front of the Baseus Blade is what we view to be the best part of this charger. This power bank has a 100W max output, two USB-C Power Delivery ports, and two USB-A ports. If you’re charging from USB-C 1 or USB-C 2 alone, you can use the total 100W if the device accepts that much power.

Charging multiple devices splits the 100W output between the ports, and that’s why this Baseus Blade power bank is incredible, as you can still charge a laptop and fast charge another three devices if you want to. That’s what we did.

For our test, we began charging with a Lenovo IdeaPad Flex 5 laptop via USB-C 1, and it could charge at its max charging speed of about 30W. We then started charging a Samsung Galaxy Note 9 from the USB-C 2 port and an LG G7 from the USB-A 1 port; the Galaxy Note 9 and the LG G7 could charge fast while the Lenovo laptop was charging from this power bank.

We also tested a Samsung Galaxy S20 via USB-C 2, and it was able to Superfast charge, the means that USB-C 2 on this power bank features Programmable Power Supply (PPS) charging. Overall, the ability to charge a laptop and fast charge multiple other devices gives you the best portable charger can offer.

Input Charging:

Recharging the Baseus Blade power bank is almost as good as the output charging, and we say “almost” because it doesn’t have a 100W recharge rate. Instead, the power bank has a 65W max input. A 65W recharge speed is still fast for a 20,000mAh power capacity; you must use a 65W Power Delivery wall charger to recharge the power bank for the best recharge time.

This power bank doesn’t have a wall charger, but a USB-C to USB-C charging cable is included in the box.

Size and Weight:

The form factor of the Baseus Blade power bank is unlike anything we’ve seen compared to other power banks. It’s such a flat and thin power bank, and we love this design; as most 20,000mAh power banks take a more cylindrical shape, this power bank offers a different shape while still being just as portable.

The charger has a length of 6 inches, a width of 5 inches, and a thinness of 0.7 inches. The weight of the power bank is 1 pound. Not exactly a small power bank, but it’s still easier to carry in hand and lightweight for everyday usage.

Functional Components:

Using this power bank is like most others, with charging automatically starting once you plug a device into the power bank. The one significant part not found on most power banks is that this one has an LCD showing the remaining power capacity, charging output, and time until the power bank is fully depleted. Having all this different info displayed on LCD is awesome; sure, most won’t care about the charging output, but having the timing of how long you can still use the power bank gives peace of mind.

Structure and Material:

The build quality of this power bank is excellent; just as other Baseus products are, this one is built well. There are no loose parts, yes the entire power bank is made of plastic, but having it made of Aluminum Alloy would make it even more expensive and weigh heavier; the charger is meant for everyday use, but remember, it doesn’t have a rugged build, so be careful not to drop it from a high fall as that could break it.

Tech:

When we charged three devices simultaneously, the power bank did get warm but not hot, and that’s what we expected, as chargers of all types always generate heat.

Reliability

If you have a USB-C laptop, this Baseus power bank is a must if you don’t mind the price. The charger has a high capacity, 100W output, and four ports, including two USB-C PD ports and two USB-A Quick Charge ports. The 100W output is the driving force behind the reliability. It gives you a more comprehensive range of devices to charge, big or small, and you can simultaneously charge those more significant and small devices with this power bank.

Summary:

This power bank has the form factor, and we love it. Most power banks tend to be cylinder-shaped and quite thick.

The build quality is strong, and the charger only gets warm when charging multiple devices simultaneously.

If you have a USB-C laptop, you need this power bank.

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.
