The once-simple telephone is now so complicated that you need a manual to figure out all its functions, and you can’t just plug it into a phone jack anymore — it needs its own source of power. Usually that means stretching the power cord to some distant outlet, but with Leviton’s Out-of-Site PowerJack you can get back that neat and clean look for your phone.
The surface-mount wall plate hides a high-efficiency regulated power supply. You can adjust the supply’s output from 7V to 12V DC, and the PowerJack comes with six universal adapters so it should work with most phones.
The catch is that you need to retrofit your existing phone wall box with a 120V feed to power the hidden supply. Leviton protects the supply from over-current, over-temperature, and short circuits, and they took the effort to get it listed it with UL. If you’re worried about phantom loads, the supply only draws 0.12W when there’s no phone attached.
Pricing for the Out-of-Site PowerJack starts around $25.
