He further criticized the company’s customer service for not responding to messages for help or warranty.
What do the stars speak of?
Opinions about this product were divided in such a proportion among the buyers.
I was really worried because I have an air mattress that has a built in pump, i didn’t know if that was going to be an issue. But damn! This thing really pulled through and did an amazing job. Totally need this if you’re inflating beds/floats on a camping trip. Totally awesome.
Goes in fault mode without anything plugged in! 🤬

Easy, compact and works great at a great price
I couldn’t be happier with the BESTEK 300W Power Inverter. It’s compact, powerful, and incredibly reliable, making it the perfect travel companion for vacations, work trips, and even camping. The dual AC outlets are ideal for charging larger devices like laptops, while the two USB ports handle my phone and tablet effortlessly. The fast-charging capability is a game-changer on the go. The build quality is exceptional—the metal housing feels sturdy, and the smart cooling fan ensures it runs quietly, even during heavy use. I also appreciate the built-in safety features, like the 40-amp fuse and protections against overheating and voltage issues, which give me peace of mind. BESTEK’s attention to detail, from the long cigarette lighter plug to the 60-month warranty, shows they truly stand behind their product. If you’re looking for a reliable and versatile power inverter, this one’s a no-brainer. Highly recommend!

C-PAP Friendly
I plugged this inverter into a 60ah lithium battery pack. It worked perfectly with my AirSense10 C-PAP.

Great little inverter
Great for the price. Best part is that its fan does not run unless it’s needed. So it runs quietly most if the time.

Works great for laptop in car
Small compact
tomdckd –
very compact unit with no sound.
Didn’t like the fact that the unit is fuse protected ,But you can’t replace the fuse because it’s soldered in. So in my case which included needing to remove the lighter plug adapter so I could connect directly to the battery and it got hooked up backwards. ( note the White stripe is the positive wire.) I had to unsolder and solder in a new fuse. But it’s working great now. :0

Carl –
Works for intended purpose.
Using this in a 2006 Dodge Caravan, got tired of messing with the radio that keeps resetting every time I start the car so put my Klipsch ProMedia 2.1 THX certified speakers in my van. Speaker only use 2 amps, 200 watts. It works and there’s no hum or noise coming through the speakers. I am completely satisfied now that I can turn up the volume and jam.
Jay 🇺🇸 –
Good
I hot this to drain a few batteries, ran it hooked to a 200 watt heater for 6 hours without any issues. Wires seemed thinner than expected but never got warm so I think they are good. Only downside is this does make some fan noise so louder than expected for such a small inverter and I didn’t max it at all 300 watts yet but seems good for what I needed

Steve –
Succeeded where others have failed.
I’ve been through so many of these inverters that claim they have the power to do all of this stuff. This one truly can do what I’ve been trying to do which is heat an electric blanket/throw and power my portable gaming pc, laptop, etc. This truly delivers the 300w that it promises, I was worried it wouldn’t be able to handle the blanket but it did it with ease. My only other concern is how long will it last as the reviews are worrisome about life of the product. I love the compact size and how easy it is to use, already paid for itself with being able to do so much.
It’s a average product but not worth its price since it lacks capacity from time to time –
High price
Decent product needs improvement on capacity and durability it only lasted me 2 months and I had to throw it away. Not Worth The Price. If I were to buy it again I’d buy it for $10 less.
Chris M –
Awesome product!!!
Purchased a Crock-pot heated lunchbox for work. Doesn’t come with a cord that plugs into the outlet in a car. Saw this and figured this would work. Today was the first use of it and very much impressed with it. I use it in a tractor trailer so it just lays on the floor and does it’s job. Quiet operation….not loud at all, but then again I’m driving a diesel truck. Highly recommend this product.

Very Useful. MAKE SURE CAR IS ON.
I use this to charge my laptop while on campus because I’m antisocial and do my work in my car. It worked great but killed my battery. Make sure car is on.
Robert K –
Low voltage output
Connected to fully charged 12VDC auto battery with confirmed 12.3VDC output, the output of the inverter, with no load on the inverter, checked 102VAC with a digital meter. Apparently a common problem with this device based on multiple reviews.
