Hey guys Im 99% sure that pimoroni makes what Im looking for, but at work the search function doesn’t work and displays garbage in the shopping ares, so I cant find it, but heres the deal.
Building a laptop/tablet hybrid. Pi4 and 10" screen (maybe larger in the end)screen wants 12V.
I had a battery made and everything works GREAT, using a buck/boost converter to drop down to the RASPI.
BUT in my current design I have a slider switch for BATTERY/AC power, but every $49 tablet at walmart has the ability to charge the battery while running the tablet.
In another forum I was recommended a hat like THIS:
and was told that PIMORONI makes one.
But heres the queston I cant get answered. See I own the one in the link, its far less than great, but for my cell phone projects it works pretty well.
HOWEVER as I said, my battery outputs 12V, to be exact its an 18000 mAh 12V Li Ion battery pak. It will run the Pi4 and screen all day!
But I don’t know that much about batteries and charging, but simple math says taking something as big as mine and plugging it into something that normally takes a 4850mAh 5V battery, is just NOT going to work.
Any and all advice is GREATLY appreciated.
EVEN if you have a lead on a 10-12" 10point touch screen that runs at 5v for under $150
