Ultra-High Capacity: The massive 20,000mAh capacity provides more than 5 and a half charges for iPhone XS, more than 4 full charges for Samsung Galaxy S10, and over 2 and a half charges for iPad mini 5. Their support of a 15V power profile instead of 12V allows for faster charging of the original Switch.

These are stylishly done, but they aren’t as clear and easy to see as the bright row of lights on my PowerCore 20100. Premium design With a sleek exterior and an LED light wheel to display battery level, PowerCore Essential 20000 PD is premium both inside and out. I’m better off getting the PowerCore Speed 20100 PD but I’m waiting for a Slim improvement (unless its competition comes out first). The PowerCore Essential is a bit bare-bones compared to some of the more featured batteries, unfortunately earning it a lackluster score in this regard.As mentioned, this battery pack is definitely on the heavier side compared to top-ranked portable chargers in our test. What You Get: Anker 525 Power Bank (PowerCore 20K) / PowerCore Essential 20000 PD, USB-A to USB-C cable, USB-C to USB-C cable, travel pouch, welcome guide, and our worry-free 18-month warranty.

Superior Safety: Anker’s comprehensive MultiProtect safety system includes overcharge protection, short circuit protection, temperature control, and more.I have the PowerCore+ 20100 USB-C and love it but its to big and heavy to carry around in my pocket. When the trickle-charging mode is on, the last LED light will remain green, regardless of battery status. But for the original model of the Nintendo Switch it allows it to charge faster (the original Switch under draws power from 12V sources). A single round power button resides at one end, and this has four tiny LEDs embedded in it to indicate the capacity that is left.
