Using Battery Charger as a UPS

Wed Nov 08, 2017 9:22 am

Hi All,
I am looking as using one of those Battery Chargers that you use for charging your mobiles battery when out on the move as a mini UPS for my RPI 2 Model B (v1.1)
The RPI will be of the following spec:

RPi 2 Model B
TPlink micro Wireless Card
DVB-T USB Dongle
16gb Sandisk Ultra HC1
32GB USB card.


Has anyone ever done this?
I have a Kodak Power Bank here
Model KPBP-K/2600mAH
the input is 5v 0.8a
output is 5v 1A

if it supports both charging and powering at the same time it can work,
that bank is really not good enough specks to meet that requirement
there is a UPS HAT you can get to make it all seamless

5V 1A will be insufficient to run both the WiFi Adaptor and TV Stick:
