Customer Review

Reviewed in the United States on September 28, 2018
I gave it to my grandparents to use on their cruise. It powered my grandpas portable oxygen concentrator for two hours even after completely charging the batteries . They enjoyed their cruise because it gave them more time to enjoy outside their cabin. I’m sold and will be buying more!
