BESTEK 300W Power Inverter DC 12V to 110V AC Car Inverter with 4.2A Dual USB Car Adapter

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!

Easy to use, compact design, great value. Use it camping, or to charge multiple devices on the go. Won't overheat, power multiple devices right from your vehicle.

I've had this inverter for over 9 years now, taken it on multiple cross country trips, including ones that have involved car camping where this was our only source of 110 AC power for days at a time. I originally bought it after such a trip where we found the 1 amp USB slots that were factory-installed in our SUV didn't put out enough juice to recharge my wife's iPad while she used it, or even get it to a full charge in a reasonable amount of time when she wasn't using it. Since then this inverter has powered laptops, portable DVD players, iPads, and phones, often all at the same time, while providing steady power and not overheating, thanks to its built-in fan.I think the few people who have had problems with this are either trying to use it with devices that draw too many amps, and/or their car's electrical system is limited and not designed for such an inverter (see further explanation below. So my advice is:1. Stick to the devices it (and your car's electrical system) were designed to provide power for, and avoid amp-hungry appliances like power tools and coffee makers I've seen mentioned in the low reviews (SMH).2. Check the specifications of your car's electrical system and its output from its cigarette lighter outlets before you buy this inverter, and before you jump to blaming this inverter when things go wrong.Car cigarette lighters are practically never designed to be on a circuit all by themselves, and depending on the car model the cigarette lighter could be on the same circuit only with low-draw components like dashboard lights and overhead interior lights (many of which would not necessarily even draw current at the same time that often), or it could be on the same circuit as a high-draw component like, say, your car's air conditioning system. That is going to make a big difference as to how much additional load that circuit your cigarette lighter is able to handle, and thus will affect what you can plug into the inverter.I personally have used this in a 2011 Toyota Venza, 2011 Chevy Malibu, 2017 Mazda 6, and a rental in 2016 that was either a Chevy Tahoe or GMC Yukon, and again, never had any issues in any of these cars, but other vehicles (including newer generations of these same models) may have the issues I mentioned above.

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.

If you have been looking for an inventor to use in your car or truck, your search just ended, and you do not need to look anymore because you are looking at the best. The amazing thing is you would think you will pay more for this top-quality product, but no their prices is very reasonable. If this unit does not fit your need, make sure you limit your search to only " BESTEK " because I know for a fact, they have what you are looking for.

Own 2 of these, they’re awesome, compact and powerful!

Works great as helps me charge all my cordless batteries so I can keep working in my work truck everyday

Great item.
