A 1 litre hand sprayer with a built-in battery pump, so there's no pumping by hand. Use it for weedkiller around the yard and garden, fertiliser, or cleaning and disinfecting liquids.
It charges by USB (lead included), and a light shows red or green for the charge. A full charge gives up to 2 hours of spraying at 1.5 bar. The nozzle turns from fine mist to jet, and you can see the level in the tank.
