Good stuff
I use this for work, and it’s been durable and helpful. I keep it in my tool box, I do line maintenance for an airline. This is rated to 500W, I can use it to charge a laptop, run equipment etc. I’ve used it for a while now and it works as expected!

Works good, but not for my application
This little inverter is perfect for running a laptop, printer, game console or other small device in a vehicle while the engine is running. It will charge all my Milwaukee and DeWalt tool batteries using the fastest chargers. Unfortunately, I needed it to run my solar powered gate opener. It ran the opener fine, but the standby, or "no load" draw was over 5 watts. Times 24 hours, that means it will use about 130 watts per day if I never open my gate. My solar panel makes just a little more than that, so this inverter simply wont work for me. There are other inverters that will open my gate (square wave, 300 watt) that draw only 48 watt hours per day.

Packaging is not protective at all
The quality control and packaging is an atrocity. This is one of the more expensive units as we wanted something a little more reliable and sturdy. It arrived all beat up and bent and the top USB outlet was messed up. Right out of the box. I tried it out before our trip to make sure that it still works and thankfully, it did. We were still able to power the kids' devices for the duration of our road trip and it seemed like it'll work out alright. I'm not sure what kind of warranty it comes with or what it covers, but this thing took quite a beating during transit to my house so I'm keeping a close eye on it for any issues. Update: I was contacted by the seller shortly after I received the damaged unit and they offered to send me a replacement unit at no charge. The replacement arrived in much better shape. It was the same packaging as the old one so it's clear that the new unit may have had a "safer" trip than the first one. I gotta give them a lot of credit for their excellent customer service The person that I was emailing back and forth with was very friendly and respectful throughout our interactions. At times they were very insistent on me updating this review; I told them I would but since I'm reviewing the product, I would need time to use the inverter and get a feel for the quality and durability of it. We've made several trips with it and it works as advertised. It doesn't seem to get very warm and it's not noticeably noisy when the fan is on. The product and the customer service definitely earned their stars back. All in all, I'd recommend it for anyone looking for a power inverter for their vehicle.

Great customer service
I just bought this back in July. I have never used it. I decided to use it right now to get me out of a bind just my luck auxiliary plug doesn’t work if I connect to my battery it works just fine. It’s just a cord that is bad if the sellers sends me another cord that’s actually works I will be glad to remove this review. Update:: shorty after I posted this comment the seller made things right and immediately send me not only another cord but also another inverter. That’s how you take care of your customers!!

Great price for 500W Inverter
We needed 110V power for our camper during off grid outings. We just needed to charge laptops and phones, run a small fan - little stuff. this little number does the job. It is quiet and cool. Under 50 bucks - sweet!

One of the better converters I've bought that's a no name Chinese made unit. Using in my truck for charging devices. Quiet operation and solid construction

Très satisfait de cet achat. Très silencieux. Bien construit. J'ai fait un essai avec une ampoule au tungstène de 100 watts. À ma grande surprise la puissance tirée de la batterie est approximativement 100 W (8,1 A/12 V). Avec une ampoule fluorescente de 24 W (équivalente à 100 W) le courant tiré de la batterie est de 25 W (2 A/12 V). Donc transformation très efficace. J'ai d'ailleurs décidé de ne pas tirer plus de 240W de cet appareil de 500. Ce n'est pas un système portable, mais c'est parfait pour la maison. D'ailleurs l'ondulateur pourra être connecté à la deuxième batterie de ma Westfalia. Very satisfied with this purchase. Very silent. Well built. I did a test run with a 100 watt tungsten bulb. To my surprise the power drawn from the battery is approximately 100 W (8.1 A /12 V). With a 24 W fluorescent bulb (equivalent to 100 W) the current drawn from the battery is 25 W (2 A /12 V). So very effective transformation. I have also decided not to get more than 240W from this 500 device. It is not a portable system, but it is perfect for the home. Besides, the inverter can be connected to the second battery of my Westfalia.

Works great with my CPAP machine. Light weight for camping, hunting and fishing trips. Very easy to use. I would definitely recommend this product. I had some question about using this device, i contacted Bestek and the customer service was amazing. They got back to me extremely fast and answered all of my questions.
