If you’re sick of old power banks that don’t hold much charge, and need an upgrade badly, the Anker PowerCore 20100mAh is one of the best portable chargers out there. Not only does it have a high capacity power storage, its fast charging technology means you get your devices powered at a reasonable pace.

Why We Like It – Anker PowerCore 20100mAh

A high capacity, durable, power bank capable of charging several times over—the Anker PowerCore 20100mAh checkmarks all the important features.

  • Very high capacity power bank
  • Fast charging technology
  • Charges two devices at once
  • Awkward dimensions
  • Lighting cable not included


When it comes to performance the Anker PowerCore 20100mAh deserves its spot as the number one best portable charger on Gadget Review’s list. For starters, it’s a two amp charger, which means it fully charges really fast, only taking about 10 hours.

What that translates to is up to is a battery capacity of up to eight full charges to a device of your choosing—iPhone X, Samsung Galaxy, you name it. With PowerIQ and VoltageBoost technology, it’s capable of quick charging (except Qualcomm Quick Charge). What if you want to easily charge your devices while you are out on the water?

Where its performance outshines many other portable chargers, the Anker PowerCore 20100mAh falls short on its design, specifically its dimensions. It is by no means a lightweight external battery; this is a beefy charger as far as power banks go. While it isn’t as wide as the INIU Portable Charger 10000mAh or Portable Charger Power Bank 24800mAh, it’s much longer. So long in length and so weighty that you’ll notice it in your pocket. In fact, it’s 12.5 ounces. Compare that with the Jackery Portable Charger Bar 6000mAh, a much smaller and less powerful power bank, and they’re worlds different.


There’s a lot of value in the Anker PowerCore 20100mAh Portable Power Bank. Not only does it have a really big charging capacity, it’s sporting two USB charging ports, allowing you to charge two devices at once. That’s especially helpful if you and a friend both need a quick charge. It also helps that the portable power bank has a solid build, too. It’s definitely a sturdy device that will certainly survive a few accidents. To sweeten the deal, a micro USB cable is included, but not a lighting cable, sadly.

Anker PowerCore 20100mAh Wrap Up

The Anker PowerScore 20100mAh offers one of the best options for steering away from wall chargers. It’s powerful, has fast charging technology, and can charge up to two devices at once. So long as you can deal with its awkward dimensions and lack of lighting cable, you’ve got yourself an amazing deal.
