I installed 1 today , it’s pretty good, the usb c port can charge my 12.9 iPad Pro 2021. $15.99 for 2 packs , I think it’s a good price.
The Brand is Litesun.
Update: I already installed 5 of them , all of them so far so good, I test them on my iPad Pro 12.9 2021 M1 which can get 14w constantly output. I think they are good usb c chargers which is not like other charger changes output watts all the times. Some RFDer even mention good brand can output 65 w from wall, I don’t want that , that would be very hot inside , there has few room left inside.

Be warned for these, if you live in an older house these may not physically fit the the receptacle box. The older style boxes were narrow and shallow. This plug is quite large: width and depth.
I had to return some, 1960s house with plaster walls

You can make it fit. Was tight but I was able to make it work.
Try it for yourself, don't let this deter you. Can always return with Costco

True, it’s really tight, I had trouble to put it in. It’s my first floor outlet which have triple wires ( black , white and ground ( totally 9 wires.

My friend said try using some lube before putting it in.
I’m not sure if that will really work.
Lurking on RFD for years. Finally decided to make an account...

These use power constantly. Can't plug the transformer out.
True, but being switch mode power supplies the amount of power they consume on standby is probably on the order of a few cents per year. The nightlight in your kids room, plugged in and off (due to the light sensor) consumes much more.

Only if the night light has an incandescent bulb. My LED night light uses only an tenth of a watt.
The way ports like these work is, they have 1 power supply channel for 5v 4.2A connected to 2 ports. You can draw 3A on one, 1A on the other one or however config you like netting to the max amperage. The more you draw towards the limit, the lesser the efficiency. Most of the smaller supplies like this one are 90%+ efficiency so it wouldn't really matter. These are good for charging your phone overnight, fast charging everyday will wreck your battery in a year so its ideal to keep a fast charging block handy and use it only when you need it. When the outlets are not used, it will cost you maybe 10c a year.

An interesting tidbit of the circuitry in a light sensing nightlight is the cheaper ones sometimes use just as much power when 'off' as they do when 'on'.
And since nightlights often use use a capacitor voltage divider (instead of a switch mode power supply) their efficiency is atrocious.
Of course, considering how low power they are the effect on your utility bill is in the noise floor, but the facts remain.

The idle power of an AC adapter based on a SMPS design is so minimal it is in the noise floor: i.e. you wouldn't be able to tell at the end of the year whether an extra cent or two went to it or not.
