Best Anker power banks: top 5 picks in 2022

Having a good portable power bank could make the difference between getting the call for that dream job and not; between binge-watching your favorite Netflix series during a long flight and staring at the seat in front of you; between conveniently navigating your way through a foreign country and having to gasp ask people for directions.

In other words, having a phone with a dead battery is not fun. Thankfully, we have power banks – an essential accessory for anyone who spends lots of time out and about… or just likes to use their phone snuggled in bed even while it’s charging. And Anker is the company making some of the best power banks on the market.

But what is the best power bank for you? How do you pick one and how do you make sense of all the technical specifications attached to every different model? Worry not as we’re here to help!

  • Anker 737 Power Bank – best overall
  • Anker 733 Power Bank – 2-in-1 wall charger and power bank
  • Anker 525 Power Bank – a more compact solution
  • Anker 633 Magnetic Battery – wireless, for iPhones with MagSafe
  • Anker 511 Power Bank – compact and lightweight

With all that being said, we’ve compiled here a list of the best Anker power banks to help you choose which one to get for yourself.

anker, powercore, select, 20000mah, power, bank

Anker 737 Power Bank

The Anker 737 Power Bank is the first one on our list for a reason: it has a huge 24,000mAh battery capacity and on top of that, it allows you to charge three devices simultaneously. The generous 24,000 mAh battery can charge an iPhone 13 completely almost 5 times, a Galaxy S22 – 4 times and a half, or can even charge 1.3 times a MacBook Air with M1 from 2020! That’s an epic amount of battery life you can carry around in a relatively compact form.

But that’s not all this power bank has going for it. It features a Smart Display which shows you important metrics like how much battery it has left, how much time it has until it’s charged, as well as other useful metrics such as Battery Health and battery cycles. If you need ultra-fast charging, you’ll be delighted to learn that the Anker 737 supports 140W fast charging (your device should support that, keep in mind), which can charge a MacBook Pro 16-inch to 50% in just 40 minutes.

Anker 737 Power Bank (PowerCore 24K)

Featuring a 24,000mAh battery capacity: charge up iPhone 13 almost 5 times or a 2021 iPad Pro 12.9 1.3 times.

Anker 733 Power Bank

Another great power bank from the Series 7 power banks by Anker is the 733. It has a 2-in-1 design and can be used as a fast charger when connected to a wall outlet, or as a 10,000mAh battery bank when you’re on the go. And, on top of that, you don’t need a separate power brick to charge the power bank itself! Additionally, it is widely compatible with iPhones, Samsung Galaxy phones, Pixels, and other devices, and can charge 3 devices simultaneously.

And, on top of all of this, the Anker 733 Power Bank features Active Shield 2.0, which ensures there won’t be any issues with temperature: it monitors temperature daily 3,000,000 times! An epic power bank, we might add!

65W power bank that can also be used as a wall charger. You can charge 3 devices simultaneously. Right now, until November 15, you can get 15% off using code ANKER1111 (apply it in the cart).

Anker 525 Power Bank

If you need a more compact solution, the Anker 525 is a great option. It still has a 20,000mAh battery, so it’s quite capable of delivering enough battery for your phone despite being a more compact option than the ones we listed above.

It may be an older model, but its reliability and compact design are why it is listed as a part of the best Anker power banks that you can get right now. It has a 20W USB-C port which can fast-charge your iPhone, and it also features an 18W USB port for when you need to charge a second device.

Anker 525 Power Bank (PowerCore 20K): save 18

A more compact solution with 20,000mAh. 20W USB-C port to fast-charge your iPhone, and an 18W USB port for a second device. Right now, Anker has a great deal on it and you can save 18 with code WS7DQUI047.

Anker 633 Magnetic Battery

If you’re looking for something different than your standard power bank, the Anker 633 Magnetic Battery is one option to look into. However, keep in mind that you can take advantage of its magnetic capabilities only with an iPhone, which supports MagSafe, such as an iPhone 12 and above. It has a 10,000mAh battery and uses magnets to attach to your iPhone – and charges it wirelessly.

On top of that, it has a built-in kickstand so you can charge your phone and place it in a way that’s easy-to-view – on a table, for example. And, last but not least, it sports a compact and trendy design with multiple color options to choose from.

Anker 511 Power Bank

For an ultra-compact and lightweight solution, we have the 5,000mAh Anker 511 Power Bank. It is relatively smaller, and despite having a bit less in terms of battery capacity, it entices with its compactness. For a little (but much-needed) battery life, the Anker 511 Power Bank is more than enough. And, it is a cheaper solution in case you’re on a budget.

But that’s not all this power bank has going for it. It also has built-in prongs that you can use to plug it into a wall outlet and use it as a charger.

How to choose the best Anker power bank for you

Choosing the best Anker power bank for you is a process that requires you to take into account several aspects:

  • How often do you plan to carry it?
  • How much mAh do you really need?
  • Do you need the power bank to be able to charge simultaneously more than one device?

Let’s address why those (and similar questions to ask yourself) are important. First off, some Anker power banks can be quite heavy (bigger battery capacity, or mAh, means heavier power bank), so if you’re the type of person to carry around a lot of stuff, you should take into consideration the added bulk and weight.

Additionally, you should think do you really need to charge simultaneously three devices, or do you need it only for your phone? Basically, if a power bank can charge more devices at the same time, it will have more ports – and this can make it more expensive. Think about how many ports you need exactly and, if you need it just for your phone, you can go for a solution that has only one port.

On the other hand, the mAh is important to be able to figure out how many charges you will be carrying with the power bank. Each power bank has its battery capacity listed in the specs. The higher the number, the more juice it can store. For example, a more unassuming option (like the 5,000mAh Anker 511) will be able to charge your phone completely just once or one and a half times, depending on your phone’s battery capacity, while big solutions (like 24,000mAh ones) will offer several charges, needed for people with a more busy schedule and more time outside (and heavier phone use when out!).

How we pick the best Anker power bank

The power banks that we listed here are picked across a wide Anker portfolio in order to answer most people’s needs. We’ve selected all-out Anker power banks for busy people and people who need to charge more devices, like phones and smartwatches, simultaneously on the go. But that’s not all – we’ve also thought about people who use their phone less often and would like to just have a piece of mind when out and about so that they won’t run out of battery.

That’s why we’ve picked the best power banks for both use cases. We’ve also taken into account the bulkiness, the extras, the price (for what you get) and even the looks.

We’ve focused our attention on selecting Anker products from the latest series the company has. We want to help you get the most up-to-date experience and the best Anker can offer in terms of design, mAh, fast charging, and added functionality.

Do Anker power banks work with both Android and iPhone devices?

Anker power banks are famous for offering wide compatibility with different devices. All the power banks here (except the MagSafe wireless one) are compatible with Android phones and iPhones. Of course, you need to have a cable with the respective connector to charge your iPhone or Android phone. Most of the power banks listed here come without a cable for your phone, so do check that in the What you get section on Anker’s website for the power bank you have in mind.

On top of that, many of the solutions Anker offers can also charge tablets and, some of them, even laptops.

Are Anker power banks safe for my phones?

Yes. Anker takes safety seriously and virtually all its charging products are equipped with a technology called MultiProtect, which monitors voltages to ensure your devices and you are protected and safe. Additionally, the more expensive power banks we’ve selected include the ActiveShield 2 technology, which also monitors the temperature to prevent overheating when charging. You can read more about Anker’s MultiProtect here.

Review: Anker PowerCore Elite 20000mAh Power Bank

Anker has made some of the best portable chargers in the market, which is really one of the reasons why they’re on our list as being one of the best brands that produce such awesome power banks. Their portable chargers are able to lead in this changing space because they always continue to innovate.

Not only is the innovation within their tech like the power capacity and charging speed of Anker power banks great, but it’s also their stylization. Their chargers look insanely aesthetic.

This is one of Anker’s newest portable power bank chargers, the Anker PowerCore Elite 20000mAh and it really brings a full package to the portable charging space of chargers. Let’s a take a deeper look at why this power bank is able to deliver on nearly all cylinders.

Similar 3-Port Power Banks:

Power Capacity:

The PowerCore Elite has a power capacity of 20,000mAh and for the Output power capacity, it can fluctuate because the power bank has 3 Output charging ports. Overall it’s going to depend on how many devices you’re going to be charging at once to really say how much Output power capacity you’re actually going to be receiving.

With that said we’re going to assume that for the most part, you’re going to be charging 2 devices at once and the max current that’s being Outputted will be about 3.5A. Then you can expect an Output power capacity of about 17,000mAh.

It’s important to know and remember that this power bank does not use Panasonic battery cells, and instead, it uses Lithium Polymer ones which is why conversion may be poorer than other Anker power banks.

Charging Smartphones, Mini Tablets and Full-Sized Tablets to Full Power

With that said, you can still get lots of full charges on plenty of devices, because this power bank is still a high capacity one. For most smartphones, you’ll be able to get 5 full charges or more. As for the tablets, you can expect 2 full charges for small tablets like the iPad Mini 1 and 2 versions.

For full-sized tablets, you’ll be able to get a full charge if you’re only charging it alone because that way you’ll be using the entirety of the power capacity.

It’s a large enough power capacity that you can use for days and possibly for weeks depending on the way you use it. The power capacity is indeed reliable enough for the 3 charging ports it has, it’s just that it’s very reliable when you’re charging small devices like smartphones.

This is mainly because smartphones don’t require a massive amount of power capacity, and the charging speed is going to be at a rather intermediate rate.

DevicesAnker PowerCore Elite (Output Capacity = 17,000mAh)Phone CapacityAnker PowerCore Elite Left Over Capacity after One Charge

Output Charging: Per Port: 5V/3.0A Max Output: 6 Amps

This is where things get the most interesting for the PowerCore Elite. That’s because it has 3 charging ports and Anker made sure that each one of the Output ports is very capable of providing an optimal charging experience.

Most of the time with powerful power banks, their standard ports are able to give a Max Standard charging speed of 5V/2.4A. That’s not the case here. Instead, this PowerCore takes it a step further with each of the Output ports being able to Output 5V/3.0A.

Very Fast Charing Through Each Port

So if you have a Quick Charge compatible device, this power bank can charge it near its max charging speed. However, it’s important to know that this power bank does NOT feature Quick Charge but it’s able to reach very close to Quick Charge speeds.

This means that you can charge nearly any USB charging device at its max charging speed. This is definitely true for tablets, as their max charging rate is 2.4 Amps. As for Non-Quick Charge smartphones, this will be able to charge them as their max charging speeds as well.

A Max Output for Stable Fast Charging

Then there’s the fantastic Max Output. The Max Output of this power bank is 6 Amps, and this means that it can Output 6 Amps all at once.

So if you’ve got 3 very high power demanding devices, like 3 iPads connected to the power bank at the same time, then it will be able to Output 2 Amps out of each of its ports so the Max Output of 6 Amps is reached. Even when you’re pushing the charging speed to its max potential it’s still able to give fast charging to nearly any device connected to it. It’s true for iPads and it’s very true for smartphones.

If you’re charging 3 smartphones all at once, then it’s very rare for the power bank to have difficulty providing the optimal amount of power to them; unless if you’re charging 3 Quick Charge compatible devices at once.

Input Charging: Both Micro-USB Input Ports: 5V/2.0A Max Input: 4 Amps

One of the most welcoming parts of this power bank is the usage of 2 Micro-USB Input ports. This is an awesome feature that is mostly used with power banks that go beyond the 20,000mAh power capacity but this PowerCore 20000 takes advantage of it.

Each of the Input ports is able to recharge at a 5V/2.0A charging speed. So if you’re using a 2 Amp wall charger or higher that has 2 charging ports rated at 2 Amps, and you’re using the 2 Micro-USB Input ports, then this power bank will be able to fully recharge in just under 6 hours.

This is a phenomenal recharge speed because with another one Anker’s power banks, the PowerCore 20100. that only has 1 Micro-USB Port, the recharge time is about 9 hours long. The usage of 2 Micro-USB Ports is a great step in the right direction because it can ultimately make recharge times for even larger capacity power banks quite short.

In this case, the PowerCore 20000 is able to recharge at 4 Amps! Anker also has another portable charger, the PowerCore 26800. that also uses 2 Micro-USB Input Ports.

Similar Power Bank

It’s quite a large power bank and a heavy one at that as well. With that said, it’s nothing absurd and we think that the size is very compliant for what the power bank is capable of concerning its power capacity and charging ports.

It has a length of 6.2 inches, a width of 2.6 inches and a thickness 1.1 inches. It’s quite heavy at 12.3 ounces and yet it’s still not a pound, so we think that’s actually a plus.

It’s indeed possible to hold this power bank while you’re charging something like your smartphone but if you’re charging 2 devices or 3 devices at the same time, then this portable charger isn’t going to be very portable as you’ll have no choice but to set it down.

Placing it into a bag will hold no problems, though.

Functional Components:

We absolutely love the design of this PowerCore Elite. It has all the aesthetic design queues that Anker is known for. With this one, the charger has a slightly curved top and completely flat bottom to it.

The bottom part is where most of the functional components are and this is where you can find the 3 Output ports on the same short-side, there’s a power button on the long side, and the 2 Micro-USB Input ports are on the other long side of the power bank. On top is where there are 4 Blue LED Power capacity indicators.

It’s just as easy to use as other Anker power banks with charging automatically starting when you connect a device to any of the charging ports and charging stops when there aren’t any devices connected. This leaves the power button mainly to be used to check the power capacity when the unit is not in use.

Structure and Material:

This thing is built really well. Anker doesn’t create any rugged power banks and most of the time we feel that is perfectly fine. This is because their power banks are just naturally built like their meant to last forever. Sure, this power bank isn’t waterproof or shockproof from falls.

However, it keeps itself together with just 2 separate pieces keeping it together and it’s all made of plastic.

It’s a perfect portable charger to take with you on road trips, possibly camping and is really meant for everyday use.

anker, powercore, select, 20000mah, power, bank


On the tech side, the PowerCore Elite follows in the footsteps of its predecessors because it uses Anker’s Multi-Safe Protection system that is able to keep charging stably even when you’re charging 3 devices at once. Also, the usage of PowerIQ and Voltage Boost keep charging fast.

Anker states that it uses Advanced Cells for their batteries but we’re pretty sure that it’s just a marketing scheme on their part because they’re not Panasonic battery cells and if they were, then they should have stated it.


This power bank is reliably universal. We say that because it isn’t exclusive to any kind of charging technology like Quick Charge or USB-C. This way, anybody can take advantage of the charging power that this power bank has to offer.

Whether it’s people that have USB-C or Quick Charge compatible device, this power bank is still able to accommodate those devices, not only that, they’re able to accommodate those devices very well.

With its fast charging through each of its ports that are up to 5V/3.0A and a Max Output of 6A, this power bank is able to provide a max charging rate for most devices from smartphones to tablets. This power bank can even charge a MacBook that can take USB-C for it to charge since the PowerCore is able to provide 30W of power.

Overall, if you’re looking for a standardized power bank that is at the optimal level of power, design and build, then this one is it. It even has 2 Micro-USB Input ports so it can be reliable to you even faster!



The power capacity doesn’t suffer too much and it mainly matters with the way that you’re using it. It has 3 charging ports and each of them is able to give a charging rate of 5V/3.0A and the Max Output is 6A.

It’s really rare, but this power bank has it, there are 2 Micro-USB Input ports that allow even this high power capacity power bank to fully recharge within 6 hours or less.


Its size and weight match the power capacity and charging capabilities. With that said, it’s actually possible to hold and use it only if you’re charging your smartphone alone. If you’re charging more than one device it’s going to need to be set down.

The look and functions are that of Anker’s usual design with its minimalistic and sleek look.


There’s nothing rugged about the charger but it is built very well even though it’s made of plastic. On the inside, there’s a range of safety tech features that charging tech that makes this power bank really stand above the rest.


One of the most reliable power bank on the market, this one nearly has it. Even though it’s lacking all the usual special charging tech like USB-C and Quick Charge, this power bank doesn’t need things like that. This is mostly because all the Output ports are optimized to provide a charging speed near that standard.

Specs of the Anker PowerCore Elite 20000mAh Power Bank:

Per Port: 5V/3.0A

Max Output: 6 Amps

  • Input:Both Micro-USB Input Ports: 5V/2.0A Max Input: 4 Amps
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 6.2 x 2.6 x 1.1 inches
  • Weight: 12.3 Ounces


This new addition to the Anker portable chargers is not only just an addition, it’s a great one. It’s in all the areas that this charger is able to deliver in. Not just its Power, Design, and Build.

It’s getting to the point where Anker truly has made a system to know just how to make their portable chargers absolutely powerful, while still maintaining a high-quality charging experience. No matter how absurd they go with the power capacity or charging speed.

First Impression

The Anker PowerCore Essential 20000 PD fills a niche of higher capacity for smaller devices. While a 30W/20,000mAh could do the same job limiting the output to 18W saves on production cost. Allowing Anker to offer this model for 20 less MSRP than its previous USB PD supporting 20,000mAh model.

The Essential has a large, round button on top. Used for checking capacity and activating trickle charge mode. Unlike some older models, there are only 4 LEDs on the button, not 8-10. Don’t expect the circle to fill when recharging, the LEDs cover less than half of the curve. The top also has a grip-friendly surface. But the bottom doesn’t, lessening the gripping surface’s effectiveness.

Device Testing

Check with your device’s manufacturer to verify which charging standards it supports.

USB Power Delivery Quick Charge 4 Phones

  • Apple iPhone 8/X/XR/XS/11/SE
  • Essential Phone
  • Google Pixel
  • LG ThinQ/V30
  • Razer
  • Samsung Galaxy S8/S9/S10/S20
  • Samsung Galaxy Note 8/9/10
  • Xiaomi Mi 8/9
  • ZTE Axon Pro 9/10

Using an iPhone 8 for testing we find USB PD phones will fast charge over the USB-C port. iPhones will need to use a USB-C to Lightning cable, not included. And Android phones will need a USB-C to USB-C cable, which is included.

For older and newer iPhones the USB-A port supports Apple 2.4A. An older, but still functional fast-charging standard. Older iPhones (4-7) can fast charge using USB-A. Newer iPhones will charge ~15 minutes faster using USB-C.

Quick Charge 3.0 Phones

  • HTC
  • LG
  • Motorola
  • Nokia
  • Samsung Galaxy
  • Sony
  • Xiaomi Mi 5/6
  • ZTE

Using a Moto G6 for testing we see Quick Charge will fast charge over the USB-A port. Anker uses their own PowerIQ 2.0 technology, which mimics Quick Charge. As such it is considered QC compatible and works with Samsung AFC technology.

The USB-C port is strictly USB PD, so no fast charging there for Quick Charge phones.

Nintendo Switch

Works well for all model Nintendo Switch in handheld/tabletop mode.

  • Nintendo Switch (original) – Charges near its max rate while playing and sleeping.
  • Nintendo Switch (2019 update) – Charges near its max rate while playing and sleeping.
  • Nintendo Switch Lite – Charges near its max rate while playing and sleeping.

It will not support the Switch’s dock, as it doesn’t offer the required output.

If you have an original model Switch (pre-August 2019) Anker’s product outperforms the rest. Their support of a 15V power profile instead of 12V allows for faster charging of the original Switch. Due to an underdraw issue of that model Switch.

Trickle Charge Mode

Anker PowerCore Essential 20000 PD in trickle charge mode

Trickle charge mode is for low power devices. Such as a Fitbit or wireless earbuds. These small accessories draw little current (60mA). So much so a power bank thinks charging is complete, and shutdowns to save power. This means a low power draw device could get only minutes of charging.

Trickle charge mode corrects for this, by forcing the power bank to stay on for a couple of hours. Allowing small accessories time to charge.

For Anker’s power bank you double press the button to activate the mode. A green LED will turn on in place of one of the blue LEDs. After two hours the power bank will switch back to regular mode. Shutting down completely shortly afterward. Or you can double press the button again to exit from trickle charge mode. There’s no harm in allowing the power bank to stay in trickle charge mode for the full duration.

No Fast Charging With Two Devices

Both ports only support 5V. Which removes fast charging options outside of Apple 2.4A standard. There is a 15W total output limit shared between the two USB ports.

When you connect a second device you’ll notice the charging resets on the first. This is the power bank stepping down to a lower output level. If you disconnect the second device you’ll want to unplug and replug the first. To make sure fast charging turns back on.

This limitation is typical of many power banks. A few can allow for one fast charging and one regular charging. Fewer still allow for dual fast charging, and those are always large and heavy. There is a limit to how much current can cross its circuits without extra hardware. Which adds size, weight, and cost.

Whether you should fast charge one device or regular charge two depends on battery levels and your immediate needs. The closer both devices are to 100%, the less impactful not fast charging becomes.


The Anker PowerCore Essential 20000 PD is a good value option for some, depending on your devices and needs. It works bests with smaller devices, from Bluetooth earbuds up to Nintendo Switch and small tablets. Its higher capacity offers up to twice the run time as a 10,000mAh model. Good if you’re charging several devices on a day trip. Or charging one device over several days.

For phones, it fast charges all iPhones and most Androids. Notably Samsung, Google, LG, and Motorola models.

For the Nintendo Switch, it charges in handheld mode as fast as any other option. The original Switch charges faster with the Essential than its peers from AUKEY or RAVPower. But the power bank cannot power a docked Switch.

By limiting the output to 18W Anker saves on production costs, and passes that on to you. The Anker PowerCore Speed 20000 PD has the same capacity, but 30W output (and no PowerIQ 2.0). It costs 20 more MSRP as of this posting. If you need to charge a small laptop that extra 20 gets you that performance. But if you only have handheld devices the Essential gives you the same performance at a lower cost.

If you don’t need the extra capacity you’ll find a better value with an 18W/10,000mAh power bank. Such as the Anker PowerCore 10000 PD Redux. It offers the same output features. But in a small and cheaper package.

About Anker

Anker has U.S. based support (web, email, phone) and an 18-month warranty. And their own online community with forums. They are a beloved brand within many USB-C communities.

Bottom Line

The Anker PowerCore Essential 20000 PD is perfect for charging small, handheld devices for long periods of time. It’ll fast charge iPhones, most Androids, iPad, and Nintendo Switch. At a cost less than a similar power bank made for small laptops.

Buy if you:

  • Need to fast charge iPhone, popular Androids, iPad Pro, or Nintendo Switch for long trips or over a weekend
  • Want to charge an original model Switch as fast as possible
  • Prefer the Anker brand and customer support

Don’t buy if you:

  • Need to also charge a laptop on the go
  • Only need to support a single device for a few hours

You’ll want a USB-C wall charger to quickly recharge this USB-C power bank. I recommend the Anker PowerPort III Nano. A small charger for your large power bank.
