Hey!
I have a lamp which is powered by a 5V power supply and I want to upgrade it by powering it with a battery pack.
The issue is I want to use the lamp while charging its batteries but as I know charging and draining at one time is impossible so I searched for simple switching circuit but I couldn't find one and im not so experienced with electronics so I can't design it myself.
The battery pack is 1S4P 18650 lithium ion battery (is it good or should I change it to 2S2P ???) I charge it with TP4056 and then convert it to 5V with MT3608, and also my lamp needs 1-2A .
My question is how should I do it or is there any products that do that ?
Thanks.
