BESTEK 300W Car Power Inverter with 3.1A Dual USB Ports

It's smaller than I expected! So far, it seems to work well with my small solar panel and battery array. I successfully used the A/C and USB ports simultaneously, and all went well! The cooling fan never came on, even though it is a hot day. I approve this product. So far.

Love the product! I carry it with me along the road to charge battery’s and devices. Just purchased it and have been using it quite a bit.

Exactly what I was looking for, works well. I chopped the wire and added an inline fuse to it so if the fuze was to blow it would blow the one I attached to it instead of the cigarette lighter. Since it takes 28.5 Amps to run I added a 30 Amp fuze.

Worked great for pumping my full size mattress for my camping tent. Totally recommend it. it did not short out any fuses on my car, I also had the car running and not just on battery mode. Had a Nissan Rogue rental.

Works great and perfect size.

Product works just as intended and is small enough to store away in your vehicle and leave it there for when it is needed.

Arrived at it should looks good, good quality

Good size do it's work and looks cool

Good product, I have several of Bestek's pure sine inverters and have been very happy with them, so buying this was a no brainer. Right now I'm using it to maintain a car battery from another battery (I know, long irrelevant story) and it works well. The fan is pretty quiet and I had to check to make sure it was actually working in a semi-noisy environment.One gripe I have about this is it doesn't come with a clamp option which doesn't make much sense for an inverter of this size. If you're using this in a car you might not be able to push it much beyond 150w current draw because many cars have a 15A or 20A fuse for that. 155w at 12v is ~13A, 215w is ~18A. And I don't think it's a great idea to push those fuses to their rated capacity, especially since you'll have to account for a small amount of overhead in the inverter itself. Using it with a clamp to 12v socket adaptor, everything gets hotter than I'm comfortable with when pushing it closer to 180w and it was shutting off around 240w. I cut the plug off and put some clamps on, works perfectly. But this is strange to me because I feel like many people wouldn't think twice about it.

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!

With a True RMS multimeter it gives out 115VAC.with 14.5 volts input when car is running.Only 95 volts output with not true RMS meter.Don't compare with house voltage; both True RMS and non true RMS will show 117VAC. Sine waves are different.

Upon first glance it does what it's supposed to do. I've had a different one that refused to work even though I'm drawing only about 60W. This one hummed along easily and I could hardly hear the fan. I only need this for my laptop and it's just fine for that. I like that it has two 120v outlets and two USB ports too. And it's very compact.

If you wlare looking for a dependable addition to your vehicle to provide power to your laptop or other electronic devices, this is an excellent option. Well made, quiet, and stylish. Not too big or heavy either. I am quite happy that I purchased this device, it charges my laptop quite well and I can use rapid chargers for other devices like my phone. I also like that it has an on/off switch.

simple and works good

REally does the job in my car. Powered both my laptop and charged my phones.

Perfect quality and performance!

Ok so yea I admit I’m a little late on this review 🤣. I am looking at buying about Bestek that has a battery connection as well so I decided to go back and look at this one I am currently using. I need one with alligator clamps for a battery so I can use it for powering larger items like a charger for LiPo batteries. Anyway I have had this inverter for over 6 years and it is still working perfectly!!!!

Great project for a reasonable price

Can run a small crock pot in the car so you can do some tailgating. Build quality is very solid. Seems like it will hold up. Price very reasonable

This works great, very easy to use we were able to charge two phones at one.

Used three month and is broken. Light does not lit up and there is no any output at all.Update: Rerate this product. Passed three months and I still received full refund. The saler is very responsible.

Worked nicely.Charging my tablet, smartphone and remote USB battery while on 4 to 6 Service calls per day

Ordered product because my daughter works on the road and she is very happy with it.

Yes ..super duper exelentePerfecto...no mas need to buy food. I use this to warm my foood in my car and Bingo. I like it so much.Probably won't work for youBut for me it changed my way to eat healthy...

Should have purchased one of these years ago. Works for long car rides and operating air pumps and laptops.
