Very Useful Accessory for RV (but with one shortcoming).
S. Jennings✓ Verified Purchase•September 6, 2023
I recently upgraded the 50ah wet cell battery of our 17' camper-trailer to a 200ah LiFePO4 (Lithium) so that (among other things) we could run a small inverter. The Bestek 300W inverter fits the bill nicely. It's quiet (some inverters emit a high pitched squeal), and the fact that it's PSW (pure sine wave) means I can run fussy electronics from it. It's also compact, solidly built, and very reasonably priced. The only downside is the package didn't include a 12V socket adapter with proper fusing and alligator clips to connect it directly to the battery. This is important since typical cigarette lighter sockets on cars are fused at 15 amps which limits power draw to approximately 180 watts. In other words, if you plug this into your car's cigarette lighter and try to run a device that draws anything close to 300W you're likely going to blow a fuse.
What I needed

Simple to use. Lets me use my fast-charge for my phone in my car.
2 plus years. Still going...

I have had this running my shed lights for 2 years. Still working great. I am buying another one for a different project.
It really is a pure sine wave.

It's quiet and I checked it under moderate load using an oscilloscope and the output looks exactly like a sine wave. If it's not exact it's at least amazingly close. I added some alligator clips in parallel with the lighter plug because 300 Watts output would draw about 30 Amps input and there's no way you're going to get that from a lighter socket :-) I wouldn't run this at 300 Watts anyway. That's a rating. I'd stay probably at 150 or lower to not push things. Even that would be 15 Amps and too much for most lighter sockets so that's why I added the clips.
But if you want to have this for running normal low power appliances, chargers, stereos, whatever - it will be fine even with the lighter plug. I'd keep the load under about 60 Watts in that case using the lighter plug.

Well, it works!

Just used it on a road trip on which I needed to work from my laptop in my car (Tesla Model Y). I have a power-hungry (my fault - hundreds of Chrome windows open) Macbook with a 96w charger, and it went straight up from 69% charged to 100% in the span of a meeting or two. The only way I could charge this previously on the USB-C port was if it was asleep. When it was awake the USB-C couldn't keep up. I heard no sound ... don't know if there's a fan, but it just worked - quietly. And it didn't seem particularly hot later.
