Could one of these rechargeable battery packs work for a rasp pi B+? Klientool and BestBuy are some options I can packup locally, plus I like Klientools. Any tips greatly appreciated...


Bestbuy option

I also notice a DIY battery pack option. Curious how hard this would be to cobble together with maybe some rechargeable battery's.

Any power source can work with the RPi - as long as it delivers 5 volts to the input, and it can supply enough current. If your battery is not 5V, it can still work, but you'll need to add a voltage regulator.

Your run time will depend on the battery capacity rating; e.g. amp-hours. There are some simple calculations in this other answer to help you estimate your run time. If you can't be bothered with the details, this answer suggests you might get 1 hour of operating time from the KleinTools battery.

  • It also has to be USB Type-C right?

  • @HenryHub: No - only the RPi 4-series macines use USB-C.
