The electric pump water dispenser is rechargeable via a USB cable. It can be used to pump out 4-6 water jugs if fully charged. The shell is made of high-quality ABS plastic, which is lightweight but solid. Simply fasten the electric pump water dispenser onto the bottle mouth. Simply tap to operate. Totally hassle-free, even for kids and the elderly. Unlike other water dispensers, the electric pump water dispenser is compact and fully portable. Ideal when travelling or camping. No more buying an extremely expensive water dispenser each year or cleaning the inside of the machine regularly. This electric water pump is very cost-effective; it's the same price as a manual drinking water pump but saves you from pumping dozens of times to pour one cup of water. With our electric water pump, you just need to press one button, 10 seconds, a glass of water!
