I bought this ego nexus escape power plus 400 watt inverter with my own money and am doing this review of it to try to help you. I think its great overall. Downsides are the smell it makes and the way it turns off on its own after two hours if you are not pulling 10 watts AC and (or?) 100 mA from one of the usb ports. The upsides are that you get pure sine wave AC power from your ego batteries. Let me know what you think! johnny
