Can I use a different USB cable rather than the cable that comes with the PowerCore 20000 Portable Charger?

Yes, other cables can be used to charge your devices with the PowerCore 20000. However, to ensure compatibility and the best possible performance, we strongly recommend using your device’s original (OEM) cable, a third-party certified (MFI) cable, or the included cable.

What kind of wall charger should I use to charge the PowerCore 20000 Portable Charger?

You can safely recharge your PowerCore 20000 in 6-7 hours using a charger with an output of 2 Amps (2A) or higher. Chargers with an output lower than 2A (such as phone chargers) will not charge as quickly or safely.

How long will the PowerCore 20000 Portable Charger take to be fully charged?

It will take 6-7 hours to fully charge the PowerCore 20000 with a 5V/2A wall charger (not included).

What devices are compatible with the PowerCore 20000 Portable Charger?

The PowerCore 20000 is compatible with Android, Apple and almost all other devices charged via USB. (Please note: if the device’s input current requirement is above 2.4A, it may charge slowly or not at all.)

Anker PowerCore Speed 20000 QC Review

Anker is one of the leading experts in charging technology, and their power banks and chargers are among the best in the market. While it is a simple device, a power bank is much more than just a battery pack to charge your mobile phone. Behind it contains complicated electronics and circuitry to ensure that the power bank holds its charge, provides enough wattage for all the different types of available devices, and that it doesn’t die out after a few charges. We had a chance to check out the Anker PowerCore Speed 20000 QC power bank. Let see how it performs.


Here is a quick glance at its specifications:


Here is what is included in the box:

  • The PowerCore Speed 20000 Power Bank
  • Micro USB Cable
  • Travel Pouch
  • Welcome Guide

All the items are pretty standard, but the travel pouch has a good cushion which will protect it from damage if you ever drop it.

With a high capacity of 20100mAh, the weight of 369g is average when compared to other power banks of the same capacity. It is not particularly light for you to carry on your body/in your. nor is it overly heavy to weigh your bag down. Despite its weight, its long slim form makes it easy to hold in your hand, even if you have a small palm.

There are two charging ports on the power bank which allows you to charge two devices simultaneously. The port in the middle (with the quick charge symbol) is equipped with Qualcomm Quick Charge 3 technology that can quickly charge your phone in a short period of time. The port on the left comes with Anker’s own IQ technology that can identify the device you are charging and deliver the optimum charge (no quick charge though). The input port on the right is for charging the power bank and still requires you to use a micro USB cable.

On its longer side there is a button where you can click to check the power bank’s power level. And, of course, the indicator light at the top will blink to display the amount of power left. Each light is equivalent to 25% of power. The image below shows that there is 75% of power level in the power bank.

One thing you have to take note of is that when there is only one light blinking, it can mean a remaining charge of as low as 2% or as high as 25%. You will have to guesstimate if the remaining charge is sufficient to last for the whole day. If not, you will have to carry a bulky paperweight along on your trip.


The power bank came with 50% charge out of the box, and I still managed to charge my phone twice (from 30% to 100%) before it went dead.

Recharging the power bank takes around nine hours (yes, that is a pretty long amount of time), but I managed to charge my phone six times before it needed a recharge.

For my OnePlus 5T, it took around ninety minutes to get from 30% to 100%. It was faster than using a normal charger (about fifteen to thirty minutes faster) to charge my phone.

The one thing that I love about this power bank is that it doesn’t get hot. I used it to charge my headphones and phone together, and it still remained cool as usual.

Can I bring this powerbank on a flight?

With a power rating of 72.36 Wh, which is less than the 100Wh limitation of most flights, you can bring this power bank along in your carry-on luggage. You can’t leave it in the checked in luggage, though.

anker, powercore, select, 20000mah



Anker’s PowerCore Speed 20000 QC is a heavyweight power bank that you can rely on to quickly charge your phone when you need the extra battery juice. If you are looking for a power bank that can charge multiple devices quickly and simultaneously and one that doesn’t need frequent recharging, I would strongly recommend the PowerCore Speed 20000.

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 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!

Anker 733 Power Bank: get 15% off now until November 15

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 Lite 20,000mAh Portable Charger

Anker provides some of the best quality power banks and other charging electronics products on the market, and you likely know that by reading our reviews, or from actually using one of their products. Their power banks feature many different of power capacities, and the best thing about them is that they’re always powerful, with their power capacity or the charging speed that comes from the ports. Recently, Anker has been releasing their new PowerCore Lite portable chargers, and with one that we’ve reviewed already called the “PowerCore Lite 10000”. It was a slim power bank that was quite powerful and easy to take anywhere that you wanted.

In this review, we’re taking a look at this PowerCore Lite 20,000mAh portable charger. This charger seems to be quite similar to their PowerCore 20100 model, and this is their way of creating new power banks with a new type of look, but it does have differences, so let’s take a closer look.

Power Capacity:

The power capacity of this power bank starts at 20,000mAh, but just like any portable charger on the market that’s not really what you’re able to use. So we’re going to get the average conversion and figure out how much you’re really able to use.

3.7 x 20,000 = 74,000 / 5 = 14,800

The average amount of output capacity that you’re actually able to use with this charger is going to be 15,000mAh. It’s still a high power capacity and this much power can be highly useful for charging smartphones such as a Galaxy S9 with its 3,000mAh battery or a Note 9 with its 4,000mAh battery to their full power about three times. Well, the S9 would be able to charge to its full power about four times because of its lower battery capacity.

To put it basically, you’re able to charge most smartphones on the market to full power multiple times.

The same can also be said about tablets, but not all of them. If your tablet has a 5,000mAh battery, then you can fair about 2.5 full charges. That said, if you want to have the ability to charge a device to full power multiple times over, then you’re likely going to have to charge a single device at a time, as charging two devices with this power bank at the same time basically splits the power capacity.

Of course, charging two devices at once is what this power bank is made to do and it can still provide a full charge that way, too.

Output Charging:

There are two ports on this power bank, and each of the ports is slightly more powerful than regular USB-A ports on other Anker power banks, as each of the ports is able to output a 5V/3.0A charging speed. Whereas most standard ports have a 5V/2.4A charging speed. The max output of the charger is 4.8A and that’s really the only downside with its charging as you won’t be able to use both of the ports at their max power at the same time.

Input Charging:

The recharging for this power bank is quite different than what other Anker power banks feature and it seems like it’s something that Anker’s PowerCore Lite portable charger is going to be featuring. As this power bank makes use of two input ports, with one input being a Micro-USB and the other one is a USB-C input port. The USB-C port can only be used as an input

The two input ports can only be used once at a time, as using them both at the same time will not result in a faster recharge rate and they each have the same recharging speed of 5V/2.0A. So you should use a 2 amp wall charger or higher to recharge the power bank. With that said, we think that making either of the input ports Quick Charge compatible would have made more sense for a high capacity power bank as it would have resulted in a faster recharge rate.

Size and Weight:

At this point, high capacity power banks aren’t exactly large anymore and that’s not to say that they’re as easy to carry around as a mini 3,000mAh power bank. Instead, it’s a lot more manageable to take these power banks wherever you’d like.

As this charger has a length of 6.8 inches, a width of 2.8 inches and a thickness of 0.9 inches. So the charger is basically the same size as most smartphones out there, such as the Note 9, except for its thickness. The PowerCore Lite 20000 has a 13.1 Ounces weight.

So what makes it feel quite large is mostly its weight, and even then you can just place it into a and bring it with you everywhere. Placing it into a back is what we found to work best.

Functional Components:

The charger is easy to use, with the two USB-A output ports and the power button being on one side, and the Micro-USB and USB-C input are together on another side. Also off to one of the sides is where there are four Blue power capacity indicators that show how much power is left.

Just like with most Anker power banks, you don’t have to press the power button to begin charging, as charging automatically starts when you place a device into the ports. If you want to turn on the power indicators to see how much power is left, then the power button can come to use.

Structure and Material:

The power bank has a great build and this is basically what you can expect from most Anker products. The charger is made of plastic, but it’s put together very well and the ports on Anker products are some of the best we’ve used as they hold on real tight to the charging cable that you place into them.

There’s etched design of lines that makes it easy to hold the power bank in your hands.


The charger does not get warm at all, and it’s something that Anker does very well at. Overall, though you can’t really expect it to overheat when there are only 4.8 Amps being released.


Despite its awesome presentation, this Anker PowerCore Lite 20000 charger is a high standard type of power bank. The USB-A ports are slightly more powerful at 3 Amps, and the recharging is more accessible as it makes use of a USB-C and a Micro-USB input. So it can be useful for someone that’s not concerned about making use of fast charging tech such as Quick Charge or Power Delivery, as this power bank does not make use of those fast charging technologies.

That said, if you do have a Quick Charge compatible smartphone, then it’s best to go for Anker PoewrCore II 20000 portable charger that has the same power capacity, but features Quick Charge.



The power capacity is enough to change provide full multiple charges for most smartphones, the two standard USB-A ports are quite powerful and the two input ports makes recharging easier, in case you don’t have one cable but do have the other.


anker, powercore, select, 20000mah

The charger has a small form factor even though it is a high capacity power bank, and you’re actually able to fit this charger into your


The build is great and it feels premium to use every time you use it.


Since this power bank does not feature Quick Charge, and if you own a Quick Charge compatible smartphone, then it’s best to go for a Quick Charge power bank, as this PowerCore Lite is an optimal standard power bank, not a fast charging one.

Specs of the Anker PowerCore Lite 20,000mAh Portable Charger:

Max Output: 4.8A

Micro-USB Input: 5V/2.0A

USB-C Input: 5V/2.0A

  • LED Power Indicator: Four Blue Power Indicators
  • Size: 6.8 x 2.8 x 0.9 inches
  • Weight: 13.1 Ounces


Even though this Anker PowerCore Lite 20,000mAh power bank is standard across the board, it doesn’t disappoint with its charging power or its build quality.

Anker PowerCore Essential 20000 PD Review

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

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

If you connect two devices to the power bank it will disable all fast charging tech.

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.
