3.8/1.3mm or 3.5/1.1mm to 5.5/2.1mm DC Jack Adapter Cable

This convenient 3.8mm/1.3mm or 3.5mm/1.1mm or 1.3mm DC to 2.1mm DC adapter cable lets you plug one of our solar panels into our optimized Solar Lithium Ion/Polymer charger!

2.1mm inner diameter (5.5mm outer diameter) is the most common type of DC plug, but you can use this adapter for anything else that has a 1.1 or 1.3mm ID (3.5-3.8mm OD) DC jack! The adapter has little springy parts inside so it can be used with 3.5mm to 3.8mm OD plugs.

Note: we received a lot of messages from customers worried that these cables look like they won't fit their solar panel connector (or have tried and failed). The first time you plug them in you really need to give it some grunt, but after that, they loosen up and it's much easier. Just give it a good push!
