At the heart of the Promate 240 is a 24,000mAh sealed lead acid battery that can simultaneously charge/power up three USB devices and appliances thanks to three full-sized USB ports and a pair of 400-watt 220V outlets. Heck, it can even jumpstart a car!
Charging the Promate 240’s battery can be done using conventional means (by hooking its charger to a power source) or by harnessing the energy from the sun thanks to its built-in solar charging port.
Another notable feature of this indoor power station is the built-in LED digital display that provides information about the Power 240’s status (power output, battery percentage, voltage, etc).
