Review on Ampeak 1500W Power Inverter With 3 AC Outlets, 6.2A USB Ports, Cigarette Lighter Port, And 16 Safe Protections - Convert 12V To 110V For All Your Power Needs by Michael Radhakrishnan

I originally bought the 850 watt version but returned it and bought this one because it went on sale and the price was almost the same.I bought this to use as a backup in case my home electricity went out. I have it hooked up to an old car battery. I used it on my fridge and it kept it powered up for a full 24 hours straight (could have been longer but I stopped it after 24 hours). Also works with powering up my TV and garage door. I haven't tested it to the max using all 1000 watts, and I don't think I will ever have the need to.I would say this inverter, with a car battery, can keep my fridge powered up and cold for at least 3 days if I cycle the power on/off every few hours. It's a great back up to have in case of emergencies.
