First of its Kind
This patented, adapter-free laptop charging system option provides the most energy efficient approach to charging groups of devices. EarthWalk’s High Efficiency (HE) system integrates a central power supply and control circuit board system to distribute simultaneous charging power to every laptop. This method of charging is up to 85% more energy efficient than charging the same devices with their supplied AC Adapters. This option also allows the devices’ AC adapters to be freed up for independent use outside of the lab and eliminates the need for installing and uninstalling the AC adapters.
