This handy 3.8mm/1.3mm, 3.5mm/1.1mm or 1.3mm DC to DC adapter cable lets you connect one of our solar panels to our optimized LiIon/LiPoly solar charger.
The most common 2.1mm inner diameter (5.5mm outer diameter) DC jack, but you can use this adapter with any other 1.1mm or 1.3mm inner diameter (3.5 - 3.8mm outer diameter) DC jack. The adapter has tiny springs inside, allowing use with 3.5mm to 3.8mm OD plugs.
