What it delivers
The Ranein RC40G-W 4-Gallon Mini-Tank Water Heater is a mini-tank heater holding 4 gallons, rated at 1.44 kW on 120 volts.
It stores a few gallons of hot water right at the fixture, so the tap runs hot at once instead of waiting for the main heater.
At 120 volts it plugs into or wires to an ordinary household circuit, which is why mini tanks are a common retrofit.
From the listing: connections: 1/2" npt; material: Stainless Steel; model: RC40G-W.
The listing gives dimensions of 14.96 in (W) x 14.96 in (H) and a weight of 21.2 lb.
