DC Power Pigtail Cable,16AWG DC Barrel Plug Connector 2.1mm x 5.5mm DC Male Plug to Bare Wire Open End Power Wire Supply Repair Cord for CCTV Security Camera,12V 24V 36V Adapter 3FT

Solid product. Not cheap material. True to wire gauge

Used to supply power to fiber modem from Li UPS. Works like a champ.

I have a set of PC speakers in my camping van. They came with a 120v AC -> 12v DC transformer. I need to run my inverter to power them and that uses way more battery power than if I could just power the speakers directly off 12v DC.This is the same barrel plug as what is on the end of the AC power cord. I wired it directly to my van's camping battery system and now the speakers run off that, using much less power than having the inverter running all the time for such a small power load.The cord and plug on this are high quality and very thick.

well insulated, seems sturdy. I used it to make a connection between a small solar panel and battery charger. I measured the existing socket to determine size and it fit great and accurate.

Works for a Starlink gen 3 router power connector. Quality good, decent wire gauge, maybe a bit expensive.

Used this to replace a frayed one on a Milwaukee jacket, perfect fit

Very simple to use. I hooked it up to the dimmer switch with the individual wires. Then use the barrel plug to attach it to the LEDs. It works perfectly.I would highly recommend the DC Pigtail for any DC voltage extension.
