I have a cheap portable 2 AA battery supply (below picture) that's used to power some devices such as portable phones, electric shavers, etc.
Im just curious... If I use rechargeable batteries in this power supply, I thought it would be very convenient if I had a way charge the batteries without taking them out of the enclosure.
So, ideally, I would first remove the currently plugged in cable in the pictures that's meant for powering devices. Then, I would use AC wall charger that has an 1/8" male minijack plug on the end of it's cable which would plug into the enclosure instead to charge the batteries.
Once I'm done with charging the batteries, I could replace the cable again. Of course, even if this did work, I dont know how I would know when the batteries are charged.
Sorry if this sounds like a very stupid thing to do. I don't know anything about electronics. All I know is it would be really convenient for me.
