4.0 out of 5 starsGood, and within spec
Reviewed in the United States on January 1, 2019
After installation, so far so good. These outlets will get frequent use, so I'll update as it sees more use.
It is a bit wide inside a single-gang box, so be beware of clearance. I needed to insulate the hot & neutral screw heads with some electrical tape to prevent arcing to my metal box. A physically smaller unit would let me give it another star, but honestly it is totally reasonable unless you have a super-packed box.
I checked voltage & output via a standard (cheap) USB power tester, and they show to be within spec (5.17 V) . Of course, actual device charging rates are highly variable, based on your device, its current battery charge, its battery health, its internal temperature, etc.
I'll update this if anything changes.
UPDATE: These are still working great for me. They show no wear despite a few years of use in my kitchen. Note that if you have less than stellar charging time, check your cable. Not all cables are equal - if your cables have more-than-tiny internal electrical resistance, you'll get lousy charging times no matter the charger you use. Cables with thin conductors or that are long often have problematic electrical resistance properties. See Ohm's Law for details.
