The Anker PowerCore 20,100 USB Power Bank is an extremely well-built product which carries out its job as efficiently and if not more quickly as other...

Here, we present the Anker PowerCore 20100 Power Bank to solve an issue almost everyone has had an unfortunate experience with, a dead battery. Most people have more than one portable device that requires charging whether it be for an iPhone, tablet, kindle or a smart watch.

The PowerCore offers an alternative to a conventional plug socket and offers an affordable, portable power bank to charge a variety of different devices. Whether it be you’re off to a festival, camping or a long journey this PowerCore can be an incredibly useful gadget to keep with you at all times to give you that charge you desperately need.


The PowerCore is a very attractive portable charger encased in an aluminium case with a matte black finish with a weight of approximately 455 grams. At first glance, it is visible that the PowerCore comes equipped with two separate USB ports that each supply the equivalent of around 2.4 amps to each device connected including an in/out USB-C charging port.

As well as this, it comes equipped with 10 LED’s built into the unit that represent the level of charge within the PowerCore, when each of these are lit they represent around 1,300 mAh of power that is available to charge the device of your choice. This inclusion is a recent update on the PowerCore as it used to have 4 LED’s but we prefer this more precise indicator among similar units tested.

In terms of size the PowerCore comes in at 184 x 62 x 24 mm which we have found is just too large for a standard sized pocket. If you’re looking for a Power Bank that is mobile and easy to store in your pockets then you may want to look into some of the smaller banks that Anker provide, however for storage in a bag or a laptop case this PowerCore is ideal. Provided with the PowerCore is a carry case made from a mesh/netted material which is very convenient when trying to protect your unit from annoying scratches or an all-in-one storage unit for your PowerCore and necessary cables.

Anker PowerCore Charging


In terms of specifications, the power core has an ultra-high 20,100 mAh capacity and this is capable of charging an iPhone 6S seven times, Galaxy S6 five times and an iPad mini twice which we think is pretty impressive for its size.  In terms of recharging, it is stated on the website that the PowerCore “in spite of its massive capacity, PowerCore can be fully recharged in about 8 hours when combined with a 2.4A charger and the included USB to USB-C cable-up to 20% faster than a typical charger of similar capacity.”

PowerCore with devices

The PowerCore supports a maximum output of 6A and when only one of the USB outputs is in use it can output around 2.4A as previously stated. If you’re looking for a high-capacity battery that can fully charge a 12-inch MacBook then the Anker PowerCore is what you’re looking for with it providing an impressive 5V/2.4A USB-C charging that can be activated by pressing the Power Wheel.

These unique capabilities found in this unit are integrated through the smart-charging PowerIQ and current-stabilising VoltageBoost technologies that are included with the PowerCore. This provides your device with the fastest possible charge of 2.4A per port that will fully charge your device in no time.
