uxcell 3.5mm Male to 5.5mm x 2.1mm Female DC Power Adapter Connector Mono Jack Converter for Replacement, Black 4 Pcs

The four plugs all were different lengths and all too short. Two of them would not even engage the spring connector in the socket and would pop right out when I let go of them. The other two were slightly longer but would still pop loose if touched or subjected to any vibration. I had to use a zip tie to anchor the plug to an adjacent plug to keep it in place. Expect to have to do something similar, or shave down the housing enough to make the plugs the proper length. The barrel sockets all fit securely. Also note, it took three weeks to receive these from China.
