This 2.1mm Barrel Jack Adapter - Breadboard Compatible is terminated with breadboard-friendly pins instead of wide solder terminals. It is compatible with DC wall supplies that have a 5.5mm jack, with a 2.1mm center pole diameter.
Product works well and seems sturdy enough but had a poor fit into both my adafruit and a generic perma-proto board. Had to bend the legs a bit to get this to fit. Ultimately it worked but could have been better.

Really useful
Really useful for power connections, but unfortunately it is not comparible with protoboards.

Perfect!
Fit perfectly on breadboard and also on prototyping PCB. Thanks.
