Hi guys, I'm new here and I was looking for a little help with a project I'm working on. I'm trying to build a saltwater battery that will connect to a phone via usb and charge the phone. However, it doesn't seem like I can connect the battery to the phone directly because the voltage and current aren't very stable. I've read online that plugging in a source with unstable voltage to a phone can mess up the phone. Is there anything I could use to get a stable voltage so I can plug in the phone safely? I was thinking of using a voltage regulator in a breadboard I have. Thanks a lot.
