The first verison of the solar charger came with a 4mm DC barrel jack on it. On older versions (4mm) it would come with a converter cable.
- If you have a newer v2 charger (June 2013+), connect a 2.1mm Terminal Block Adapter onto the panel using basic wires, or a 1.3mm to 2.1mm adapter cable then plug that into the 2.1mm adapter. This is the fastest method
- If you have an older v1 charger, you can use the terminal block method above OR cut the adapter cable in half and splice the 4mm connector onto the panel. The panel will plug right into the board but its more work.
Grab one of our adapter cables, it will let you plug in the solar panel directly
If you have a panel with something other than 2.1mm or 1.3mm connector, you'll need to remove any existing connector. Cut off whatever connector is on
For this you'll need a 2.1mm Terminal Block Adapter but its really simple. Just open up the screw terminals, slide the red wire into the + hole and the black wire into the - hole and retighten! Now you can just plug it directly into the charger (or adapter cable).
This method is a little tougher, but results in a nicer cable. You'll need some heatshrink as well as some item with a 2.1mm DC barrel plug (like the 2.1mm adapter)
Cut off anything on the opposite end.
