Top-Rated BESTEK 400W Car Power Inverter: DC 12V to AC 110V Adapter with 5A 4 USB Charging Ports Review

I've had it less than 12 months and only used it 4 times or so. He stopped working. The big problem is that they don't honor their warranty. No consistent replies via skype or email. Facebook answered them, but it's still a dead end. Publish this accountability review. Facebook post attached.

While it appears to work exactly as advertised, be aware that this thing is VERY LOUD. Even if no load is connected to it and it is idle when it is on, the fan runs at full speed. No intelligence to control fan speed for different load and heat levels. Trying to use this while camping can be tedious as the audio is quite distracting.

We are avid campers and I have built a portable battery pack using multiple deep cycle batteries. I originally purchased a refurbished 1500W Cobra CPI 1575 inverter from Revain through a third party. Well unfortunately the Cobra looked quite worn and was not working properly when it arrived. Since I needed a converter as soon as possible for an upcoming hike, I chose this smaller 400W inverter to charge mainly smaller types of electronics. Cell phones, cameras, chargers, laptops, night lights…

I was looking for an inverter for a caravan to power my AC fridge on the go. I calculated that I would need about 260W of 12V DC (including inefficiencies) to power a 200W AC fridge. I connected this inverter directly to my trailer battery. This product contains two fuses, one for input and one for output, but an extra fuse on the power line is not a bad idea. The kit includes both clips for the battery and an adapter for a 12V socket.On the block itself, each option is attached with screw…

Bought as a gift, this set was a hit. The design is good and includes everything you need to make it a stationary unit that plugs directly into the car's 12V DC supply, or use it as a temporary portable inverter to power AC devices when traveling and around the world to provide electricity for holidays. Consider the power consumption and requirements of your devices when plugging it into the cigarette lighter. Although the inverter is rated at 400W, the power of the cigarette lighter can be…

The first converter I received did not work properly. The USB ports were getting power, but I had no power from the AC ports. After some troubleshooting at Bestek (I contacted them through their Revain profile) I was told the item would be replaced. A few days later I received a new device and an email with a return label so I could conveniently return the defective device. The new device works perfectly. I was so happy Bestek supported their product because I looked at other inverters but none

I bought this after learning how to turn on my CPAP machine when camping - I have a ResMed S9 with a 24v input I chose one for a number of reasons Inverter decided: A. The DC adapter costs about $100. B. I would get more benefit in many other applications with an inverter. for about half the price. I've read that a DC adapter would be more efficient as it would draw less power, while the inverter option is less efficient as it basically takes DC, converts it to AC and then back to DC. Then I…

To calculate DC power: W = Voltage x Amps To calculate AC power: W = pf x Voltage x Amps Pf for resistive load 1: This is a simple motor Pf for inductive load Average 0.8 electronic loads or inductive motors. So far, so good. I got this, ran to my truck, hooked it up to a 12v outlet and an air pump for a Coleman mattress. Have it on and off. It's not too big: 6 inches long, just over 4 inches wide, and 1.5 inches high. Supplied with battery clips with 22" cable and 24" long 12V socket. It has 4
