Where the power comes from is the whole question · review
A brass touchless faucet for 1 or 3 holes that runs on 110 V or four AA batteries, with a mixing valve and both supply hoses in the box.
A deck plate in the box covers the outer holes of a standard 3-hole sink, so this converts an old two-handle faucet to touchless without new drilling. The mixing valve replaces the handles under the sink.
Like the Greenspring here, it runs on 110 V or on four AA cells. The Charmingwater is battery-only.
3.5 inches of height and 3.5 inches of reach are the smallest figures on this shelf. That is fine for hands at a powder-room sink, tight for anything else.
Sensing distance, run time, battery life and flow rate: none of them is on the page. The Greenspring publishes the first two.

Yes, on a 3-hole sink: the deck plate covers the outer holes, and the mixing valve under the sink takes the place of the two handles. You set the temperature once at the valve.
Either: 110 V for continuous operation, or four AA batteries for an install with no outlet. The listing gives no battery life; the Charmingwater on this shelf states six to eight months.
For washing hands, yes. It is short for filling anything or rinsing a face over a deep bowl, and the reach of 3.5 inches puts the water close to the back of a wide basin.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
