Here’s a quick battery review for you. We got the Energizer XP20001PD Ultimate power delivery battery pack on sale at Fry’s Electronics last week. With the 20Ah power in a convenient form factor, it looked tempting.
The packaging is very enthusiastic, referring to the pack as ULTIMATE and calling it a “PD RocketHub.” As far as we can tell, there’s no USB hub functionality to be found. There are a pair of short charging cables included though: One USB-A to Micro-USB B and one USB-C to USB-C. There’s also a tiny instruction sheet.
The XP20001PD has a 74Wh/20000mAh battery with four USB-A ports (5V, max 4.2A over 4 ports) as well as a Micro USB input for charging (5V/2A). The distinction for this pack is a bi-directional USB-C port, supporting 5V/3A, 9V/3A, 12V/3A, 15V/2.4A both ways, as well as charging at 36W with 20V/1.8A and outputting 45W at a 20V/2.25A profile.
We only tested USB-PD use cases, in and out, since there are many better options if you only need to charge USB-A type devices (like the RAVPower 22000mAh 5.8A three-port pack or the Anker Powercore 20100 4.8A two-port pack).
