    these ones:

    can only supply 800mA
    that's not a problem for most uses, but you dont want to charge a phone with it.

      Re: power bank cases.

      I just ended up getting that little board since i couldn't find a case for enough 18650's to make 94Ah....
      Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

      Excuse me while i do something dangerous


      You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

      Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

        i dont like sticking them in parallel.
        it only takes one to internally short slowly and it will kill the set.

        that's how most of my laptop packs died.

          And then sticking them in series requires a charge controller...
          Guess you can never win... sigh.

              now that's both series and parallel... worst of both worlds!

                nice idea, but no sign of a protection board.
