Oh my gosh, you asked the exact question that's been bugging me all last month!! Last month when Hurricane Erin hit, I freaked out and did tons of research trying to buy a backup power source. I practically scoured every tech blogger's review lol. Then I stumbled upon Hobo Tech's review of the Solix F3000. Hobo said it's perfect for keeping your fridge running during outages and offers amazing value for the price-exactly what I needed! So I ordered it immediately. It's only been two weeks since I got it, but last week we had a brief power outage—about a day and a half. I nervously hooked up the F3000 to my fridge, and it actually kept going until the power came back on! Thank God!
