This is the Booster Pac ES5000, ES5000C, and ES6000 DC Charger with barrel plug.
I am happy with the AC Charger-Barrel Connector and charge up then it full.... Thank you...
Did what it said it would! And arrived super-fast. Not a problem in sight!
This is the charger for the battery pack booster I bought from Napa. It works just like the original and charges the pack up and keeps it topped off.
