Great Product and Great Value!!
I purchased a few of these to put in our service trucks for our technicians to be able to power up their laptops and other equipment. Not one complaint on these. They have worked great for everyone!!

Northern tool hit a home run with this excellent priced inverter. Great to run coffee maker and small fridge when we travel. Works excellent off cite as well to run power tools. I highly recommend this product, you cannot beat its price or performance. Glad we purchased it.

Ask the questions first
Two things discovered after opening the box.
1.) Max current from the cigarette lighter is 120 watts. There is a tag on the lighter cord indicating this.
2.) This unit isn't designed to work in the winter or Arizona (that is; below 32 degrees or above 104 degrees F).
Also there are a couple of inaccuracies in the Q&A section.
1.) I could not find nor did the manual reference
"two 25A mini slip fuses". Maybe disassembly is required to get to them? In the troubleshooting section of the manual, if there isn't any power output, it doesn't even suggest checking fuses. There is an 8A/250V slow blow fuse in the tip of the lighter cord however.
2.) In my case, the fan came on the instant a 10W load was applied, therefore not being "controlled by a thermostat".
A very good thing about the unit is that the two outlets grab plugged in cords really tightly.

Rockstar that gets the job done
I first picket up of these units to connect to a car battery for a renegade power supply for music/lights/fan while camping and it got the job done. Since then I have increased the setup to a mobile cart with 6 12v SLAs for the total completely portable party solution. The PartyHardCart oficially endorses NPower inverters as a reliable cost effective device for getting AC power off the grid!

45 day failure
I bought this inverter to replace one I had for about 10 years which finally failed. I thought I'd try it for the price. It lasted about 45 days, actually less because I used it about 2-3 hours a day to power my laptop about 3 days a week for six weeks. I'd say it lasted about 45 hours. I would not recommend this product.

Npower 400 watt inverter
I wanted an inverter inside my pickup truck for chging cells and Kindles. I was given a bonus when I hooked it up to my lawn mower battery, and was able to plug in a jigsaw for an off site job. The alarm came on almost right away that I was draining the battery, I started the mower engine and sawed away. Very convenient and readable manual. I did buy the extra 1 yr. warranty. It's also small enough to store inside the truck cab with no problems.

Works well, but a little loud
Purchased this for charging batteries for track side support - electric impact, data aquisition, cameras, laptops, etc. Works fine, but doesn't have an alarm for a low battery in the 12v source. After 30 mins of admittedly hard use (without the truck running) it drew the truck battery down to where it needed a jump. There was no indication that the truck battery was getting low. Other inverters have this feature. Not a big deal to me, but be aware. It works fine if the source vehicle is running, and inside the truck the cooling fan is a little loud. If you can tuck it under a seat and maintain ventilation you don't hear the cooling fan much.

I ordered this inverter to run a coffee maker, but the instructions said that it would not work on anything that heats up so I used it for a fan in my camper and charging up cell phone and flashlights, It worked great. would recommend it to others. It is at a great price
