EarthWalk’s HE Power Hub:
Patented Charging Provides All-Day
Power to Laptops & Chromebooks

The High-Efficiency (HE) Power Hub charger system provides the world’s most convenient, energy-efficient approach to charging groups of laptops and Chromebooks. This patented charging system integrates a high-performance central power supply and control circuit board to distribute simultaneous charging power evenly to every device. This method is up to 85% more energy-efficient than charging the same devices with their supplied AC adapters.

The Power Hub has a variety of deployment options: Power Hub can be mounted independently (ex. on the wall of a classroom) or integrated into just about any cart to provide increased performance, ease of operation and electrical savings. It is also portable and gives you power wherever you need it—perfect for all-day, online testing.
