Good charger/ product. I would buy it again!
Good charger but it was the battery that ended up being bad. Install was easy when I broke the case open. Easy to identify and trace the connection and replace the charger. Slapped it back together and charged again but acted up and showed the battery was the issue instead.

Just the right adapter i needed.
This is exactly the right AC adapter for the Harbor Freight Centech jump starter and air pump.

Fixed Centech Jump Pack
If you're not 100% sure your existing charger is failed, test it with a multimeter on the white connector end. It should be pushing about 15 volts. My failed charger was very intermittently jumping around, never going above 0.5 volts. This new charger works perfect for my Centech 630.
