From the Manufacturer

Plug this inverter directly into the 12-volt cigarette lighter socket in your car to power up a mobile office, entertainment electronics, handheld games, TVs, and more.

Each compact unit stores easily and provides hours of emergency power during snowstorms or blackouts. The high-efficiency design transfers 90-percent of the battery's power to your equipment, providing 400 watts for 5 minutes, 600 watts surge for easy startups, and 300 watts continuous power for operating appliances. An automatic shutdown mechanism protects against overload, over-temperature and low battery conditions. The inverter is equipped with two 3-prong grounded AC outlets.

This item works as advertised, but it is a modified sine wave inverter. If you are planning on using it to charge cordless tool batteries---don't. The owners manual contains a caution about using with cordless tool chargers (such as Dewalt). Do a quick Internet search on "cordless tools" and "modified sine wave inverter" to confirm whether your tool is effected. Some other items that may not work well are appliances with clocks, microwaves, etc. Be sure you understand the limitations of a modified sine wave inverter.

For those smaller appliances that will run on modified sine wave, this item works well.

Real nice unit, but I wish I had bought the Xantrex 700 watt unit instead. For instance, I have a small auto vacuum that need 6 amps. This unit won't handle it. This unit can attach to the cigarette lighter or directly to the battery. The 700 watt unit skips the lighter input -- fine with me but maybe not with you. If you need lighter input then get the 400 watt unit. I will say that the inverter is well built and designed. I like the fact that the power input leads are attached via screw posts. This lets you modify it as needed, for instance if you needed longer leads, you could make your own and not have to kludge it.

It couldn't be a better time. Yesterday noon I got the X-Power 400 delivered by UPS, and in few hours it was put to its ultimate test. Yes we were hit by the 08/14 Thursday North East Blackout. But with the help of the X-Power 400, I was able to hookup the 13"TV and Dish receiver. Enought to spend the restof the evening siting in the desk and watching the CNN news update and TV programs with family and friends. I love the cigrette adapter and the battery clips.
I used the battery clips to get power from my car battery.
I recommend X-Power 400 for any regular household use. If you are planning to operate power tools, I suggest get the 700 or above.
This 400 is smart, small in size packed with all the energy to keep your entertainment rolling without any interrruption. My original intention to use my Laptop on my roadtrips, but this proved to be much more useful than just powering the laptop.

We bought this power inverter to power our daughters nebulizer and a t.v. and playstation for the kids on road trips. The only problem we had with it is when your using over 150 watts power you are supposed to hardwire it. That requires additional wiring. Other than that it is an excellent product at an excellent price!!!

I purchased the Xantrex 400 Watt Inverter. We also have the 700 Watt. I bought the 400 for $28, including shipping, on Amazon. Great deal. My husband gets 40-60% off at a distributor, and the $28 beat his best.

My husband wanted me to get a 700, and he would hardwire it to my car battery as he did his, but I didn't want to. I wanted portability. I needed an inverter so that when I go to our storage room, which acts as my stock facility (I sell on Amazon and eBay) I could plug it into any one of the several cig lighters I have throughout my large and long Expedition. Location of it plays a big part in its convenience for me. I just plug in my computer, recharge my cameras batteries, recharge my iPod and phone, and plug in a lamp if needed. I liked the fact that I could just plug it into any car, hardwired I could not do that. This unit is completely portable. I am an avid tent camper, and we also enjoy boating, so portability is a major plus. Nothing like camping in the great outdoors, but still being able to watch a movie while snuggled up in the tent. With this, I run an extension cord into my tent, and I have DVD and a lamp or fan if needed.

I live in south Florida. I am no stranger to hurricanes and their adverse effects. A portable inverter helps with power outages, and recharging all of life's modern conveniences making the sting of losing power for 3 weeks just that much easier. With this little beauty, I can directly clip my inverter onto my battery, as if hardwired, and it provides higher wattage or amperage, whichever you call it. When it is plugged into the cig lighter, it can only provide what that specific outlet was set up to deliver, which I think is 100 on almost every car model out there. Directly hooked on the battery, it gets close to 400.

This device is perfectly doing what it is supposed to do. It either works from cigarette lighter or directly from the battery heads, very powerfull. It beeps when car is not running to remind you that it is using car's battery and shuts off automatically when battery is low before it dies. It brings the comfort of your home to your car

its a little misleading because if you plug this into a cig lighter you can only get a max 100W. if you want higher wattages you have to connect it directly to the battery with the alligator clips. RTFM
