I bought this as an upgrade to a couple 150W cigarette plug models that couldn’t hack having a heating pad plugged into them. This model is a tank. Fan sound isn’t bad but it sits behind 2nd row seat. I imagine back seat passengers would complain about fan noise but we rarely carry passengers. No detectable electronic noise in stereo, scanners & mobile/handheld radios. I would/likely buy another for 2nd vehicle, or as a gift.

I take this inverter with me in my truck wherever I go. I'm able to charge camera batteries, my laptop, and other batteries that I might need. It's great on car camping trips and other adventures.

Been able to make camping trips alot better. Charge electronics, use pumps for air beds etc.

When I used this inverter to charge some low power appliances, I can’t hear any voice from the fan at all. At first, I thought the machine was broken, because I thought it was normal to hear the the voice from fan because dissipating heat. So I was initially suspicious with the product, but when I charge the coffee machine, the fan turned on. After several attempts, I found that the design of this product was excellent. The low-power product did not cause severe heat, so there was no need to start the fan. Instead, the high power one need it, and the sound of fan also not so lould .This is also commendable.All in all, I think designers have a perfect score in this respect.

I took this to Iceland and Paris. Works perfect on the car to charge all tablets and phones--I even plugged in a refrigerator to it. Its compact design was perfect for airline travel. And driving in Iceland, this inverter was invaluable. The plug ends fit snugly in the sockets and stayed there no matter where the inverter had to sit (under the seat, behind the seat, in the back of the camper van with the refrigerator). It worked flawlessly during 9 days of rough travel that would have suited a four-wheel drive jeep better than the little van with 13" tires that we had.

I can't wait to try out this product as soon as I receive it. It's really work as the same as the description.I like the appearance of this product. What I am most satisfied is the charging speed when I charge my two mobile phones. I have to say, it is really very fast. Although I am also worried about whether it will destroy the battery of my mobile phone, so I have consulted with the service, and the service explained that they would not. There are a lot of charging ports, you can charge multiple devices, and of course, what I'm talking about is the total power is less than 400W.

I have it for a month and experienced two road trips.This is awesome! I can plug it in the cigarette lighters in the motorhome and charge my devices. Or hook it up to the motorhome batteries and watch tv without running the generator! (I will say, though, that it's a little inconvenient since those batteries are under the steps to get outside, but that's a different issue and nothing to do with the inverter).This a very well built product. Automatically turns off when voltage is dropped. I've own it for almost one year and it has survived working in the exterior (though not designed for that) and a short circuit when I mistakenlly inverted the polarity when connecting it to the battery (the included fuses worked properly avoiding any damage).

I received this Inverter and Installed it into my work van to run (2) 20 volt battery chargers, and also to use (3) of the USB outlets. Having used a couple of different brands of 400 Watt inverters, I was very happy to see that this did not get hot under the same power conditions of the previous 400 Watt inverters. It is made very well, and even though it's early, it comes with a full 18 month warranty and I am very happy with this Inverter, it's made of good quality, and runs very well... Will do a follow-up in the future. And the price was very reasonable for this unit..

These things are great for powering laptops in police cars. We've used some other brands in the past, but they didn't seem to hold up very well. For the most part, we've had pretty good luck with the ones from Bestek. They seem to be built pretty solid and have very few problems. Think I've had one or two replaced under warranty over the years, and it's a painless process if you need to do that. I've probably ordered about 15 or so of these over the past 3-4 years.
