The Efest EMP20 Power Bank comes with a pair of USB power outputs, one that produces a typical 1.0 Amp charging current and another that outputs a higher 2.0 Amp current for fast charging, allowing you to charge multiple electronics at once so you are brought back up to speed in no time! You’ll always know exactly how much charge is left as well, thanks to the power bank’s handy LCD screen, which displays the remaining percentage of the pack’s power.
