Go Power! GP-SW300-12 300-Watt Pure Sine Wave Inverter
I use it to power my sensitive electronics in my Rv. This is a high quality piece of equipment. I am currently power 2 tv's, a surround sound and a dvr. I have had it a week and would definitely recommend it. Here's my vid review https://www.youtube.com/watch?v=_5I3r6iv0eo&list=UU6fTCFP8dRkuxFv16C9-8BQ
