## Description

Powerful 20,000mAh capacity to charge an iPhone 13 over 4 times. Delivers fast 20W charging speeds with 3 USB ports for charging multiple devices simultaneously.

Review: Great Anker product - Really good speed of charge. 6 or so iPhone charges I think. If you hold the power button light goes green and lowers the output so it can safely charge smaller items like earphones. Nice design, bulky but that’s why you buy this one so no complaints. great stuff from anker as always.
Review: A good item for travel - This item comes in very handy as somebody who relies on his devices while travelling. It's able to charge two devices at once, and supports fast charging with the appropriate cable. It doesn't support ultra fast charging, but it's good enough. It also has sufficient capacity to keep multiple devices charged all day - I used this to charge both my phone and my action camera, and on my last holiday I only had to charge it every other day. Overall a good item. The only negative thing I can find so far is that the writing which states the capacity is very small and hard to read. This caused delays at half of the airports I went through, due to the time being big, when they tried to check it was ok to travel. But this isn't enough to take off a star.
