Jensen JP30 300 Watt Power Inverter

This power inverter worked great during a 1400 mile round trip, family vacation road trip over Christmas. It powered everything we plugged into it: cell phones, laptop & iPods. Only complaint would be the slightly noisy fan. Wasn't too noticeable, since I was able to place it in the armrest compartment. Other than that, would definitely recommend. The size is perfect and seems well built.

Will this product work when the engine is off? My jeep has extra plug in outlets with continuous power access with the engine off. I want to use my laptop in my car on my lunch break. Will the battery hold up for this draw amount? with the engine off? Thanks for your response. Sylvia :o)

It's like magic to me the way this inverter works. I bought it to be able to record outdoor sound samples from a car, so for my purposes it will power a small sound board and a laptop. I tested it with the equipment I plan to use, and then for about a four hour drive using my camera recharger and a pair of audiophile computer speakers. The inverter provided unfaltering power, was quiet, and stayed absolutely cold to the touch. While the music played I forgot it was even there. I don't plan to push it to any limits so I can't speak for its maximum capacity, but for running electronics such as computers and sound equipment it's excellent.

Quiet operation with both outlets going,non surge with start up's.
Great product with a low price.

This product worked fine, there was a little fan noise but tightening the case screws fixed that.
