  1. I have one of i ball a chinese company…
    It has a nature pic printed on the front with a flat last gen usb wire
    At 3500 mah its good for me as a student …
    I can even use it as a bookmark sometimes its like 1cm thick…

  2. I have a smaller home-made one with my old phone battery that is around the same size as this but have 2800mAh battery (new battery will had 3000), I simply bought a power bank PCB, removed the big male USB port and directly solder the USB cable with the connector to it, I glue it thoguester and I wrap it with the plastic cover of a paper folder, and that's it, how much it cost me? 3 dollars for the power bank controller board.

  3. I wouldn’t buy that thing it’s thin yeah but the biggest issue is when the lightning cable breaks or is pulled out too much

  4. Incase you didn’t know, you can buy drill batteries at 50,000mah for like £25 and an attachment for like £10 which means it’s a power bank.
    A beast of a power bank. It’s big, but it’s a thing ?‍♂️
