By Joanna Terrero: After reading the mixed reviews, I hesitated, but now, I’m glad that I bought this inverter for emergency use in case of power outage during storms. It works great. I’m using a 12-volt battery to power it, which I charge with a solar panel. So far, I tested it with lamps, USB lights, a laptop and charging my cell phone. I’m getting a second one, and I recommend it for sure.

By outwest: After having blown numerous converters which claimed to be rated for the amps that I was needing (aerobed for camping), I have finally found one that can deliver consistently. Yes, it works for the cigarette lighter and can clamp directly to the battery. The Cobra had no problem delivering the necessary current for the aerobed from the cigarette lighter and, unlike many converters which oddly just appear to fail while in storage, the Cobra has repeated this feat over and over. It certainly is bigger than the ones that have a built in cigarette lighter plug, but having the capability to go straight from the battery for heavier loads is great. For the price, size, and reliability, this unit is perfect.
