400W Power Inverter Review:
Had a laptop and mobile phone charger plugged into this for an total 12 hour road trip with no concerns. The green light is not too bright and changes colors in case you are utilizing too much energy. Having two outlets was a lifesaver considering we had various electronics that necessary to be plugged in. The cord might be a bit longer, however it does include two sets. One of the cords plugs into a cigarette lighter (or similar outlet) as well as the second cord could be attached to a battery. I wouldn’t desire to put this in a backpack to carry, however it is excellent for in the automobile or to hook up to a battery for emergency power to get a radio or laptop.
