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

Do not purchase if you want to use it on your Tesla. I bought it to work on the go while on a cross country roadtrip while stopped at Rest/Service stop. Didnt go as planned this thing doesnt work on Tesla.

this will be a helpfull tool when we go tot the field

Cord length is great. Not too short and not too long. I bought this to do breathing treatments in the car while traveling using a nebulizer machine. Works great. Just make sure the car is on. I have also used it to do my treatments when the power was out from PGE while in my driveway. Just turned on the car and kept in park the whole time (40ish minutes). Can plug in a laptop and charges it. Ended up buying 2 bc I lost it when I moved and it’s been so helpful! I’ve recommended it to many people and they love it too!

The product is small and lightweight and works well for charging my Blackberry and Dell laptop. Its quite so thats a plus. Only downside is I wish the cord was a bit longer.

I took out my ashtray and mounted this in the dash board. looks like its part of the car now. have my phone plugged in to charge with its fast charger. kinda noisy even in the dash but cant really hear it when the cars running so very minor issue.

I direct wired it to my battery it seems be working great.

Unit requires a heavy set of direct battery connections to utilize its full potential but most definitely worked for cigar plug. Nicely packaged. Seems well built from the outside.

A MUST HAVE. I drive around for work and if I forget to charge my cell or laptop - having this in my car is a life saver. I drive a small economy car so this is as much voltage as I can use but its fine.

Enough for things like a laptop charger but anything like a vacuum or requires more power doesn’t work well.

The fan is pretty loud and it doesnt seem to charge my phone very quickly and when running GPS it only slows the inevitable drain of the battery. It worked well enough with my laptop and other devices, however, so I would still recommend this.
