Charging via USB cord.
You can use an electric cylinder by placing it on both 12-liter and 19-liter containers, without installing it directly on the bottle, installing it in any dimension.
The height of the crane allows you to install a kettle on the cylinder as well.
The piston has 2 power buttons, one of which is a sensor: when the tank is installed on it, the piston starts working.
The price includes a cylinder, a stainless steel faucet, a silicone tube and a USB cord.
A six month warranty is provided.
