Coleman Rechargeable Quick Pump - Troubleshoot UB645 Battery Issue

Thanks for the info. I believe that in my case, the blower's internal circuitry or motor is fried. I left it out in the sun following a mattress blowup. ..very sad .. it was a great unit.

Nice video and Happy New Year! Larger DC batteries can be dangerous though! Please use caution with larger batteries. Accidentally placing a wrench between positive and negative on a car battery can cause an explosion.

You’re right, thanks for the words of caution!

Can I just bypass the battery and connect directly to the DC current. also I think even though it says 6vdc in on the pump and 7.5v output on the adapter. the multipter shows 13v on the adapter output. so may be i need a differnt adapter i want to bypass the battery so it can work directly on DC supply. I am also thinking that there are usb to dc6v adapters availble that can be pluuged into the rechargable external usb battery and possibly use that.
