Good. Makes 3 amps out and does not get very warm.
Works quite well. Tested at 12.3 volts input , it will actually deliver 3.0 amps at 4.93 volts which is better than I expected. (NOTE: One of my USB power meters turns out to not have a good connector, making my initial impression much worse.) I enclose some measured voltages with an adjustable USB load, from no load up to I=3.0 amps. It does not get very warm. Peak efficiency is 0.89 at 1 A, and it is still 0.82 at 3 A output. Quiescent draw (no output load) is 6 mA at 12.3 V input. I wish the MFR would publish this kind of data but I guess they figure no one cares.

It works for an ipad
We use it to keep an ipad charged and the hardwire to 12v makes for a cleaner installation instead of a cigarette lighter plug. If the ipad is used all day, the charge won't stay at 100% but it's possibly (probably) because the battery is getting old and not the adapters fault.

Worked Great for Dashcam, Died After 2 Years in Texas Heat
Using this in my car, which is not garage kept, for a VIOFO dashcam. Worked well for 2 years. The heat and vibration finally got to it, now it draws 0A and outputs nothing. Wish there was an automotive rated one on Amazon for a few dollars more... This one is still excellent for the price.

These work
I’ve installed these on 2 motorcycles tucked behind fairings to power CarPlay head units that run off 5v usb. no issue with power delivery.

nice little out of the way hidden power point
so for all you people that like to add toys to your vehicles and hide them, this is the way to go, you can tap in to your rearview mirror cable and run you this in your headliner and not have any cables hanging down in the window or have to run that cable across and down to the cigarette lighter plug for your dash cams or radar detector or even you phone mount power cords.

Monté dans mon camping-car. Simple à installer et fonctionne sans émettre de lumière qui empêche de dormir.
