  • Well built inverter.
Style: 400W
It's well built and sturdy. It will be used to charge 20v tools that I use to take care of my property.

  • Very reasonable priced!
Style: 400W
This 400W inverter is absolutely amazing and works perfectly. It’s powerful, reliable, and very easy to use. I’ve tried many others before and this one is by far the best. It runs everything I need without any issues and feels very well made. Great value for the price and definitely worth it. Highly recommend! ... show more

  • A little power house!
Style: 400W
I've had this (400 watt model) a week now and have only done a couple of function tests; so far so good. I use it to power a 32 inch LED TV, a 200 watt soundbar and a Blu-ray/ DVD player in my travel trailer. It will run them all at the same time with no problem (such as electrical interference with the TV picture or sound). When not using the Blu ray player or off the over the air antenna, I use one of the USB ports to power an Amazon Fire TV Stick; again, with no problems. I also just use the trailer 12 volt power plug to run the inverter. The fan does not run when the inverter is turned on, only when powering something. Now, the inverter fan does make some noise when it's running but you quickly get use to it. Or in my case, just turn up the TV volume! One of the things I really like about this inverter is that it has mounting tabs. I have it mounted to the wall below where my TV is mounted. I used a couple of small rubber faucet washers under each screw to hopefully help with vibration and road shock while traveling down the road. This also might help a little bit with keeping it cooler too by providing a air gap between it and the wall. I also got a three way adapter plug from Lowe's to be able to plug in the various size transformers. ( I really wish all the electronics manufactures would design a standardized size transformer plug that would fit the same anywhere!) This adapter also happened to match the orange of the inverter. I like it enough I ordered another to install in another part of my trailer to run another TV and my printer. My only complaint is the location of the on/off button; it's close to one of the 110 plugs. If something is plugged in there, it's a little difficult to reach the on/off button. Only time will tell how well and how long this inverter works. Especially inside a moving RV on the wonderfully well used roads in this country! ... show more

  • Fake warranty, outlets won't charge a laptop
Style: 400W
I bought this and used it sparingly for 3 months, mostly using the USB ports to charge phones. When I plugged in a laptop, it the 3-prong outlets stopped working. The outlets were not even capable of charging a normal laptop. The manufacturer apparently thinks the inverter might not be capable of charging a laptop through the car outlet, which just about any inverter should be able to do. They had me hook it up to the battery to see if the laptop was drawing too much power, which was silly. They also said the outlets probably broke from overuse, which is ridiculous because I barely used them and only charged cell phones on them unit I tried my laptop, and I only had the inverter for 3 months. Also, after awhile, the plugs would work to charge cell phones but not the laptop, which shows this is a defective item incapable of charging a laptop. The company claims to have a "hassle-free" 18-month warranty. They also claim to have "100% customer satisfaction," which is essentially impossible and also false based on reviews. To get them to acknowledge a warranty claim, I had to spend time making videos showing how the outlets did not work with my laptop and also had to connect the device directly to the battery, which I never do. They customer service responded quickly, but after I did that, they told me to contact Amazon to make a claim on their manufacturer's warranty. Amazon does not take those claims. Amazon only accepts the return within 30 days. So after the 30-day window, the warranty essentially is up. I talked to three different Amazon chat people. The first person said I could return it if I paid a 20% restocking fee, which makes no sense for a defective item. The second person said to contact the manufacturer again. The third one said they would give me a "one-time exception" and refund me. Amazon sucked up the refund, not the manufacturer. So if you actually want to make a warranty claim, you probably have to get lucky with the customer service representative and may have to try several of them. ... show more
