"PROS: small package, easy to read display, lots of charging options, affordable CONS: takes 4 hours to fully charge using 120v cord *Test Run: This unit powered my 12v fridge (3/4 full, temp set to 34F) for 12 hours and still had 17% battery left. Once I add a 50w solar panel, this thing will work even better for me."See all customer reviewsSee all Solar Generators & Power Banks
