BESTEK 200W Power Inverter, Car Plug Adapter Outlet Converter with Dual 4.5A USB Charging Ports, Cup Holder Car Charger with Cigarette Lighter Socket for Laptop, Computer (Cola Red)

Update:Dec 2024 (more than 2 years now): The device is still working well. The main problem before was voltage drop when car was put in drive mode. To make this work, I have to use a victron 12v to 12v DC converter to provide stable input voltage for the Bestek inverter.Old review: I have this for about 1.5 year now.In the beginning, it works fine. After a year or so, the fan starts kicking and creates loud noise whenever I turn the car on. My devices draws about 100w.After a long time of struggling, as of 2024-05-30, I finally find out this is the culprit that causes power problem to my devices (not my car cig socket, or the fuses, or the relays). The power keeps dropping to 0w and repeat every 3 seconds or so. This "phenomenon" only happens since last year and only when my devices draws more than 30w. I believe that after a long time , the inverter overheats and causes some internal failure.Now, I need to find a more endurant inverter for continuous power draw.

This is an ideal product if you trying to charge lots of things in the car. The fan in the first unit failed after a couple of weeks, but the customer service was excellent and they immediately sent us out a new one which has been working very well since then.

Works perfectly. I love that it fits in the cup holder!!!

It’s ok for a while, but after that, it’s turn noisy, quality was good, easy to use, not too weight, like it

Amazing.... It's quiet and keeps everything cool due to the breeze that comes from it. I'm a truck driver. I totally, recommend it.

Used this inverter in my work truck in order to heat my meals and charge my phone. This inverted is a beast. It lasted 6 years and the only part that stopped working was the usb ports. Highly recommended.

So I use this a lot so I can charge my phone and use my dash cam at the same time. It works great and I've had no problems with it. The biggest "issue" is that the sound of it can be "loud". It's not unbearable, but it's definitely noticeable in a quiet vehicle. But I listen to music as I drive, and the sound of the road kinda drowns it out so it doesn't bother me at all.

This worked fairly well over the last year and has been useful on many long trips. Haven't overheated it and I've plugged a 65w gaming laptop into it for a few hours (playing middle of the road power hungry games). The interface is fairly clean and straight forward. Decent room on top for two plugs and two USB. Power is fairly consistent. The cord is long enough in both our vehicles without being obnoxious. I thought the vent fan being on the bottom would create heat issues but so far no problem.But there are a few other problems. The cord is kind of obnoxious the way it connects at the top and goes straight out. A 90 degree angle cord would have helped keep this more in shape and managed. As it is, the cord has to go out and loop back to wherever you need to send it which can get in the way sometimes. The lid should be detachable. It gets in the way, especially if you have a cup in an adjacent holder. And if it's loaded with wires, it's a pain to deal with. And the worst issue is that the power button no longer works. It seems there's a little plastic brace which the toggle button sits in. But the plastic is very fragile around that spot. If you push to hard on the button or the device gets jostled too much, it can snap it. And it's a tint screw that keeps it attached to the rest of the chassis so only super glue or clever reconstruction will get it back working. My work around was to open it up, engage the power button (always on) and never touch it again. If I need to turn it off, I just unplug it. Simple enough. Probably doesn't even need a power button. I guess if access to the plug is something you don't want to fuss with during a trip, this would be a deal breaker.

Ordered this dandy little device to charge my grease gun battery. About a month into having it, and after Amazon's return window closed, it started making a loud noise like the fan was broken. I reached out to the company directly, and they did not hesitate to offer a replacement, which arrived super quick and in great working order. Highly recommend.

Es un poco ruidoso por el ventilador que tiene pero funciona muy bien!

Amazing product! Do what it is supposed to do. Decent speed charge time (cause sometimes some devices claim to have 2.1 amps but it's more 500 mA) :P I didn't try the 2.4 amps usb plug cause I have nothing that is compatible. I really enjoy this device but it could use come improvements. The two A/C outlets are too close from each other to be really useful. I suggest you put some decent space so we can use the 2 sockets at once.Well, this thing has a cup shape but since usually the 9V outlet is just in front of the car cup, then you just can't put the device in front of the 9V plug. So you basically lose a cup place. That happens in my car so I had to improvise. That would have been nice a 90 degrees 9V adapter for people like myself.This being said, outside these few "inconveniences" the device look neet and reliable. Only time will tell now.

Bought this inverter 4-5 yrs ago because:1- Size: it can fit verically in a cup holder or consealed in the centre concol of a car.2- it has a shot off switch3- It’s vented with a fan4- it has 2 plugs5- 2 usbA (one of which is 2.4 Amps)6- it can give 200 Watts but max out @ 500W7- ran approx 500 hours so far (sometimes 24 continuous hours) no issues8- WILL CLEAN ALL & LUBRICATE FAN ONLYSafe for the car. No shorts, no blown fuses, no problems. HHad it in a car where ppl ate peanuts and dust all over it. Still works. There is Made in China, and then there is Made to promote a better reputation of Chinese companies and Manufacturing industry in general.I got lucky.

I've been wanting one of these for a while and after not having electricity for 4 days I realize that having this to charge my laptop and other things is so important to have on hand. Price point is good and great quality
