12V DC Power Converter, PI Store Adapter, 110V to 120V Transformer, 10 Amp 12V Max, FCC & CE Approved, for Car Refrigerator/Car Cigarette/Lighter/Other Car Accessories Use

No noise; at least I don't hear it. It's very hot when I am using it to charge my power stations around 90 watts. I will setup a fan to blow it to cool it down, and it works perfectly. Charging speed is as described; able to charge power stations slowly. That's the intended speed. Reasonable price.

Works great. I bought it because I have a tire inflation pump that plugs into a cigarette lighter, and I wanted to use it for other things far away from my car. It does exactly what it is supposed to do.

I use this converter to power air inflator for cars. I do not have a cordless air inflator. So, when we are at home, plug this converter into the household electrical outlet is more convenient than using the car cigarette outlet. It is able to provide power upto 10A which is good enough to run the air inflator. Solid built and seems to work for a long time.

The converter is doing what I bought it to do and has worked great so far. I needed to plug in a tire inflator (Slime electric) for car tires and a lawn mower. It worked great. The only reason I'm not giving it 5 stars is because it comes in a plain white box, no logos, name, manufacturing information, nothing, and no paperwork of any kind. Not that you need instructions, but, something about the product is usually included. When the boxes have no printing on them and no paperwork, it makes me feel like I'm getting the generic, bottom of the line product, possibly not as good as it could be or as what is described. Again, working fine, just an unknown factor with the container.

Worked fine for roughly 24hr total use. Stopped functioning when we really needed it. Using with a 12v cooler.

I purchased a tire compressor for my scooter. I went thru two ac/dc adapters as I didn't have a vehicle where I could use its lighter socket. The first one I had, not even a sound. The second, the display lit up but it only made my device hum. I had checked the amps, voltage but finally after doing research realized the whole thing came down to watts. So I read the various reviews and saw my ac/dc adaptor ram on 115 watts. Now realizing what was my the problem I knew what to look for. I saw this one sold by P. I. Stores and it goes up to 120 watts so I was hopeful. It worked perfectly! I'm very pleased and can finally use my cigarette lighter device. It came will packed and arrived quickly too! Don't waste your time with the other adapters if you have a nice cigarette lighter device... It's not worth the frustration!

Sometimes I want to use my tire pump in the garage, this let's me do that without having to start my car. Works as advertised.

used it once and went to use it again after it sat for 2months it just cut off and don't work
