Some people need a power bank to keep their phones charged throughout the day, and there is a wide range of products available on the market.

One of Anker’s best-selling products is the PowerCore 20100, one of the company’s most popular products in the portable charger space.

Does it suit your daily needs of recharging your phone, tablet, and other accessories? We have created this mini-review so you can get answers to those questions.

Design and portability

Considering its size, the Anker PowerCore 20100 is extremely portable. Over the years, the company has improved the design of its power banks a lot, and this is the best we’ve seen yet.

Because the edges are rounded, you’ll find it easy to carry, and you’ll be impressed by how light it is at just over 350 grams, considering how much battery is hidden inside here.

A good way to understand how heavy this is is to compare it to a can of soup. This will not be heavy enough to notice in a bag, but it is also not light enough to comfortably fit in your back pocket, even though it will probably fit.

There is not much going on around the sides of the device. The top side of the device has four lights that light up when you press the button on the rounded edge that powers on the device.

The lights indicate how much charge is left in the battery, so if you see only two of them on, you know there’s about 50% left. We found it to be a good general gauge even if it’s not the most accurate.

With the Anker PowerCore 20100, you can plug in your own charging cables and charge two devices simultaneously at the same time. 

In addition, there is a micro USB port for charging the charger. The USB-C version is a bit more expensive at the moment, but it does have a slot.

It’s generally recommended to select the USB-C version, as it should be able to charge faster, and the vast majority of modern smartphones use this universal USB charging standard.

Anker PowerCore 20,100: Charging

The test we used to determine how fast you can charge your device was to use an iPhone X and time how long it took each portable charger to charge it from 0 to 100%. After drying our iPhone X we plugged it in and found it took two hours and fifteen minutes to charge.

If you decide to use a power bank with Qualcomm QuickCharge 3 technology and you have a compatible device (which the iPhone X is not), your phone will charge quicker.

Anker doesn’t offer that option on all chargers though, so you should check in the listing to see what features the charger has.

An Anker PowerCore 20100 battery with a capacity of 20,100mAh can fully charge an iPhone X seven times before it needs to be recharged again.

Depending on how quickly your phone charger from the power bank, your results may differ, but you can be sure this charger can charge an iPhone X at least seven and a half times.

With a battery capacity of 2716mAh, the iPhone X is relatively small for a smartphone in 2018. Your phone won’t get seven charges, but it will still be quite a bit depending on the size of the battery inside your phone.

Apple’s iPad Pro 11 has a 7800mAh battery inside, so this charger should be able to charge it up at least twice.

Charge time for this charger is likely to take around 10 hours, so you’ll have to wait quite a while for the power bank itself to charge. Additionally, Anker says that some chargers with lower amps will take longer to charge.

Is there anything else I should know?

This charger doesn’t offer any exciting extra features, so there’s not much else to know about it. Micro USB cables are often included in the box of chargers, but you’re better off using the cables that came with your devices.

If you’re worried about the Anker Powercore overheating, the company has developed a technology called MultiProtect Safety System. The company says it uses 11 different techniques to ensure the safety of all your devices.

It can be used with all Apple and Android smartphones and tablets, according to Anker. As well as charging some laptops and MacBooks, including the 12-inch MacBook 2015, it may not be compatible with all devices.

Often you can find out which devices the charger is compatible with on the online listing you’re looking at.

Pros Cons
Slimline design Takes 10 hours to charge
Large capacity No exciting features

Conclusion

As a bare-bones device, the Anker PowerCore 20100 does what it says on the tin. Despite its speed, it may not be as quick as charging your phone from the wall.

Moreover, the PowerCore 20100 should be able to charge most small devices, like your smartphone, several times.

Anker’s charger is a good option to have in your bag for those times when you’ll need to charge your devices. If you’re able to find it at a good price, it’s great to keep in your bag.
