BESTEK Power Inverter DC 12V to AC 110V - 300W Car Plug Adapter Outlet with 4.8A Dual USB Fast Charging Port - Car Charger Cigarette Lighter Adapter for Phone, Laptop on Road Trip - Aluminum Housing

Works well.

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

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.

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

I finally judgement day has come for this power supply car charging device! And I must say it has surpassed my expectations. The night I made the purchased man did I look at a lot of products and read a lot of reviews. There was a lot of mix feelings and I had narrowed it down to this product and another brand. I decided to take a chance with this one as it was about a couple of bucks less. And I am so glad I took the chance. Not only did I get a good bang for my buck. This sucker has endure a couple of water spills! The value of the product is definitely worth it even though I can't afford to dish out. Lol totally worth it for how I have abused it. 😬 So durability checks out great. The power consumption is amazing. I have been able to keep my laptop alive. Not able to charge the battery but at least I can turn it on to use it and do what I need to do quickly. And I can use my super charger for my phone and I love how it has two wall outlets and two USB connections.

I recently picked up the BESTEK 300W Power Inverter for long road trips and weekend camping, and it has truly exceeded my expectations. ✨ Highlights: • Consistent Power Output The pure 110V AC outlet delivers reliable power for devices like laptops, small blenders, or mini coolers. I ran my MacBook Pro and phone charger at the same time with zero hiccups. • Dual USB Convenience The built-in 4.2A dual USB ports are a game-changer what a time-saver to charge phones, tablets, and power packs all at once without needing extra adapters. • Robust & Safe The inverter stays cool even under continuous load, and the built-in safety features (overload, overheat, low-voltage protection) give me total peace of mind. • Compact & Portable It fits neatly in my glovebox, with a sturdy metal body and a 12V plug that locks securely in the socket. I’ve not faced any looseness or disconnect issues, even on rough roads. • Reliable Build Quality The unit feels rugged, the fan is surprisingly quiet, and the power switch is solid no loose parts or rattles after weeks of use. 🚗 Real‑World Use: • During a camping trip, I powered a small coffee maker every morning without draining my car’s battery. • On a long drive, I kept my phone charged and Nintendo Switch running simultaneously perfect for kids’ entertainment without arguing over ports. • My GoPro camera got charged up between hikes, and even emergency inflators and tire pumps worked flawlessly. 👍 Bottom Line: For anyone needing reliable AC and USB power on the go, the BESTEK 300W Car Inverter is a standout choice functional, well-built, and budget friendly. Five stars all the way!
