Battery-Free

[Devonian]

Well on the watch front I use a Seiko Solar divers watch which as you can guess is powered by light, just like the citizen eco drive watches, so no batteries needed.

For other applications, I have a small fold up solar charger for AA and AAA batteries, but I'm currently looking at a larger solar panel setup (circa 100w) which will be used to keep a couple of 110ah 12v leisure batteries charged up.

Then I can use 12v invertors to provide a 240v supply that can be used to charge any portable devices, as well as being used to plug in a normal 240v AA/AAA/C/D cell battery charger for charging rechargeable batteries. It can also be used for charging phones and baofeng uv-5r or other radios/comms, as well as for 12v lighting etc...
