Hi guys. I've been working in a project gameboy pi like. In this case, I'm using a rasbperry pi 3 and a massive 7" touch screen powered via one single micro USB connected to the pi.
In the past I built the gameboy pi zero, but I'm finding some obvious problems with this new project.
I tried using the same battery and charger as before. This is the battery:

and as a charger I am using the arduino powerboost 1000.
This combination only allows a 1A output, which is not enough (the undervoltage symbol does not go away no matter what, and in some extreme situations, the rasbperry pi resets). I tried plugging the whole thing to a 2A charger and it works like a charm.
I need a battery and a charger which allows me to get those 2A, but I have no clue about where to begin searching, I'm pretty n00b at this. Any recommendations?
Thanks!

PSU and Charger...

other 2A charger are available...
https://www.aliexpress.com/item/10W-3-7 ... 4c4dD5QXG2
but Helder is tried and tested....
and if using in a Retropie builld, will offer additional functions like a on-screen battery monitor and other functions (check his listing)
(i've used one in a Wii U build with a Pi3 and a 6.5" HDMI LCD.... and NO under voltage)
you can use any 3.7V LiPo battery. size just depends on the available space you have (and how much you want to spend)
