Electric Paddle Board Pump for Inflatables, 22PSI SUP Air Pump for Inflation and Deflation of Standup Paddleboard and Mattress with 12V DC Car Connector and Portable Boat Accessories

I got 2 good uses out of it and then as I was pumping up my paddle board today it made it 12.8 lbs. and just died. There is a burning electrical smell emitting from it and it won't come back on, so going back for refund.

I used the pump twice. The second time it began to smoke after a few minutes then shut off. It is completely fried and I cannot even contact the seller from my original order!
