## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked fine for car accessories
*by M***R on September 26, 2025*

Worked great - added a bluetooth adapter to my older car stereo - the adapter has a USB plug. I didn't want to snake the USB cable to the cigarette lighter, this kept everything behind the dash. Clean install, power works fine, connection is tight. Handy little thing to have.

### ⭐⭐⭐⭐⭐ Easy hookup
*by S***R on August 21, 2025*

Easy hook up and works well simple and clean .

### ⭐⭐⭐⭐⭐ Good. Makes 3 amps out and does not get very warm.
*by A***R on June 22, 2025*

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.
