This is not a passthrough charger. If you try to use it as one, you will soft-brick this battery. You'll break fast charging on it. Do not try to use it while charging it.That said, once I looked up the solution, it was pretty easy to fix.This thing is great. I originally bought it so I could play my handheld gaming pc away from outlets for longer, but that need lessened so now it mostly keeps my phone charged while I'm at work for longer periods. I charge it once every week or two.
