    Bought this for camping to blow up air mattresses etc. Works great and can power a variety of devices. I'd recommend the higher watt output (this model is 400 watt) over the lower watt models as I needed the higher output for my air mattress that had a built in pump. it's about $20 more for the higher output but if you're going to do tail gating or want to power a wider range of devices this is the way to go.

    I like this power supply and would recommend it. It comes with a USB port which I used to charge my iPhone as I drove across country and also a plug that I used as well. It did the trick!

    I bought this unit to power portable DVD players in our SUV. Installation was super easy. The power cable was a bit short but it worked great in helping us power up from the outlet all the way in the back of the vehicle. It is a bit noisy but we placed it behind the rear seats to dampen the noise. No complaints with that.

    I get this power inverter so that I could have a printer in my mobile office, a Dodge Ram 1500 crew cab. The inverter works great, if a bit noisy. My only complaint would be that the connections should be 6 to 8 inches longer for a little more mobility.

    The price was a little high, and I thought it could use a digital display for more accurate status reports. Still way better the the other products I've tried.

    I recently took a road trip on my Harley Road Glide to the Death Valley National Park and camped every night for a week. This inverter kept my heated gear lithium battery, cell phone, bluetooth helmet communicator and flashlight charged right from the lighter port on the fairing.!!!!

    Simply attach the leads, plug device into lighter, turn it on, plug laptop cord into it and use. (Best to have car running.) Or it will charge your laptop as you drive. Will also charge phones. Easily stores most anywhere in car.

    This is a great ac adapter for the price. You get both cigarette and car battery adapter connections. Additionally, you get dual 110 ports along with a USB port for charging.

    This replaces a very old inverter that is not as modern in design, plus this new one is so much more powerful at a lesser price point. I can run everything I need from my truck now when I'm up at the country place.

    I have a lot of video taping to do on the go. Instead of waiting inside my office for the batteries to charge, now, with this inverter I can charge them in my car and get the work done faster. I am saving a lot of time.

    Great power flow when on the road. The current flow in this inverter remains constant and doesn't seem to be affected by or fluctuate its power flow when driving.
