Solar Powered Battery Charger
Ma, look, I built a solar powered battery charger.
|5W Foldable Solar Panel||US$29.95||eBay|
|Batt. Charger||R$ 95.00||Hardware Store|
|1.5mm^2; Wire||Zero||Junk Box|
|Power Poles||US$ 8.00||PowerWerx|
Now, the specifics.
The solar panel is just that, a 5W, Foldable solar panel from eBay (seller is vitabon).
Quite compact, weighs a bit less than 2 pounds.
Then, there is the trailer connector to PopwerPole, from Powerwerx. Came in quite nice, because I didn't wanted to screw the panel. As you can see, the lead wire is a bit short.
The Y cable I built with powerpole from an unspecified origin.
The battery charger is on of those dual source, ie.: both household AC and cigarette lighter adapter. The plug is one of those fairly standard, altough I don't know the exact dimensions. Negative jacket.
To say this project was costless is an overstatement, but all parts are useable on other settings. For instance, I bought the panel with SLA charging in mind, then I bought the OPP from W4RT, so instead I'll power the FT-817 from the panel while charging the OPP inside the radio.
I have two of those panels, so I can charge batteries on the other, for the camera and GPS.
Yeah, I plan to be pedestrian mobile on the trail with the wife. I'll carry hamstuff, she carries the other panel with battery charger.
