2.1MM (0.8") CO-AX POWER PLUG

Bought this with a DCJ-21 jack to fix a rusty/worn jack on a Tennis Tutor ball machine. Wired this plug up to the Duracell 2A charger from All Electronics, and installed the jack, and now it charges fine with no flaky connections. The plug seats very solidly in the jack, so the two work well together.

Well-engineered product protects inlet wire from kinking and breaking @ end. Plast. collar twists off and back on after wire ends have been secured w/ solder joints, fairly easy as the solder points are reas. large and obvious as which is - and+;great to set up PS-1637 into a usable PS. Price is much less than other suppliers. A/E has many other adapters for DCSID.
