## Description

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 Adafruit's [solar panels](https://core-electronics.com.au/large-6v-3-4w-solar-panel-3-4-watt.html) into [Adafruit's optimized Solar Lithium Ion/Polymer charger](https://core-electronics.com.au/usb-dc-solar-lithium-ion-polymer-charger-v2.html)! 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.
