    Powerocks Super Magicstick 2800mAh

    Works from time to time, had to peek inside.

    Battery is a cmicr18650f8 rk, 2800mAh 3.7V - don't know who made it.

    Lithium battery charger is a CN3062 - 500mA
    Mosfet is a Dual N-Channel Enhancement Mode MOSFET

    Blue light = 70% – 100%
    Green light = 30% – 70%
    Red light = 1% – 30%

    Going to resolder the small board and see if it works.

      powerocks too
      if it were mine i would lightly flux everything and reflow with an airpen.
      had an ebl with 3x18650 given to me to recycle and the tp4056 wasnt soldered well.
      it would thermal trip in about 15 seconds.no wonder the 3 panasonic 3400's in it never charged!

        Thanks for the teardown pics.

        On ebay, I know there are a lot of fake nimh AA cells where the label says 3000mAh, but when tested it is more like 700mAh.

        I wonder if the 2800mAh cell you found inside is really more like 600mAh?

          Resolder the top two boards did not help.
          Going to resolder the lower button board too.

          I have no way to test batteries capacity but my phone is a Htc One S with a 1650 mAh battery - I have no problems recharging my phone from 20% to 80% and then from 20% to 60% on one Magistick charge.

            i have a cubic shitload of their 2200 mah 18650 from new laptop packs that were bought by some school then given up for salvage.
            they are at least decent cells that meet spec.
