Power bank charge controller?
I want to build a power bank but can't find a suitable charging controller.
I would also like to be able to charge it quickly, for example 2-3amps or 30watts
I will have 3.7v Li Ion cells 4 times

It uses a single USB-C port for input and output, you can add a USB-C hub supporting USB-PD to have multiple outputs. Cooling required for higher wattages according to some of the comments.

    @Xdqwerty there is health behaviour you can add to your character, then to use a health bar is lil more complicated, google n watch a few tutorial video on it, be too hard to explain here.
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, the character has the health behavior
  • BigOnYa @ BigOnYa:
    I know you have to create a health and health max variable. Then there is a calculation you use in code to subtract width size of the health bar. Google few vids.
  • BigOnYa @ BigOnYa:
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, the "greenflatbar" is one of the preset health bars btw
  • BigOnYa @ BigOnYa:
    Yea you can use any bar/sprite. It will just change the width. Ok good luck and have fun. I'm off to go shoot some pool at the bar. Talk to you later.

  • Xdqwerty @ Xdqwerty:

  • Xdqwerty @ Xdqwerty:

  • BigOnYa @ BigOnYa:
    I never used the mobile or online versions, just the pc version.
  • Xdqwerty @ Xdqwerty:

    I was at the bar for 1 hour and lost $40 playing pool, and said well that's enough for my unlucky day, better quit. Some sharks up there today.
