Where the power comes from is the whole question · review
A battery-powered touchless bathroom faucet that states its battery life — six to eight months on four AA cells — with an under-sink mixing valve and 1.2 gpm.
Of the three touchless faucets on this shelf, this is the only one that says how long its batteries last: six to eight months a set. It is the figure that decides the running cost of a battery faucet, and the one most listings leave out.
There is no plug. If the vanity has an outlet, the Greenspring and the Yodel here run on 110 V AC as well as batteries, which removes the question of replacement altogether.
The sensing range. How close a hand has to come is not given; the Greenspring states 15 cm, about 6 inches.
A shut-off time. The water runs while hands are present. Nothing says what happens if something is left in front of the sensor.
The model numbers. The page shows CW-2103-C as the model and CW-LT13 as the part number. Keep both if you need a spare.

With the mixing valve under the sink. You set it once to the warmth you want; the faucet itself has no handle. It suits a household that always washes at the same temperature, and is the standard arrangement on touchless faucets.
No. The control box runs on four AA batteries, which Charmingwater says last six to eight months. The Greenspring and Yodel faucets on this shelf can also run on 110 V mains if there is an outlet in the vanity.
A battery solenoid faucet stops opening when the cells run down. Keep a spare set of AA batteries in the vanity; the listing describes battery replacement as simple.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
