Barrel Jack Adapter 5.5mm to 3.5mm

Replacement: There is no direct replacement for this product. We stopped carrying this product because the cost was far too high, and the use was fairly rare.

This is an adapter from the stock SparkFun power adapters to a smaller barrel size. Adapts from 5.5x2.1mm to 3.5x1.2mm.

Customer Comments

  • I’m looking for an adapter that is the reverse of this; I have a 3.5mm jack output and I’d like to plug that into the LiPo charger.
