Customer Reviews

Works fine!
I purchased this product to blow up an air mattress while out camping at Cook Forest, PA. It worked fine with the two large air mattresses. It does state to not use it to charge devices such as cell phones. I used it for my cell phone and it did charge it but the phone started to act up a little. The phone is working fine now so I'm not sure if the problem came from the inverter or not.

The Unit I Had Wasn't Up To Snuf
I had previously purchased a Xantrex 851-400 inverter to run in conjunction with a marine battery so as to power lights for my jewelry booth at Art Fairs. I was very happy with it but when I decided to expand my use of lights, necessitating a second battery and a second inverter, for whatever reason I decided to try the Whistler PI-400W and save a whopping $7.55. Big mistake. The Xantrex will operate flawlessly for 2 days sucking enough juice out of that marine battery to operate 75 watts of CFL bulbs for 8-10 hours each day. The Whistler worked well for the first day but kick off after 2 hours of the second. The first time that it happened I rationalized that perhaps I hadn't fully charged the second marine battery but after making sure to test it again with both batteries on successive weekends, I got the same result both times. The moral of the story is that Amazon does a great job of refunding your money during the first 30 days and don't get cheap when making your purchase. If you find a product that does the job well that you need it to do, pay the man!

Plenty of power
Plenty of power to power a 13 inch crt TV in my semi truck with just a cigarette lighter plug.Only drawback is at startup my truck must be running to turn the TV on.After that it has plenty of power and i can turn off the engine.Perhaps i have to hook it up directly to the batteries to get more power ,which i will be doing with the supplied cable
