The Last Charging System You Will Ever Need

Our new and innovative HE-Z system (the latest generation of our HE technology) saves time and money, via a two-part wiring design: One half of each cord is hard-wired into the carts/labs with a universal port that accepts connectors from any brand of device. The other half of each cord has device-specific connectors that fit into the hardwired ports. Plug & play interchangeable technology—no tools necessary; mix & match brands of devices in a single cart; no hassle with AC adapters; compatible with all data/energy connectors including USB-C. EASY peasy!


Go Green iconHigh Efficiency Highlights

EarthWalk’s patented High Efficiency (HE) technology is the world’s most energy-efficient approach to charging groups of laptops and Chromebooks. The HE charging system operates at up to 85% AC to DC conversion efficiency compared to charging computers’ batteries with the traditional AC adapters that come with the devices. This means much less electricity is needed to charge the same group of computer batteries, therefore saving a tremendous amount of electricity and electrical cost over the life span of the cart.
  • Does NOT require the use of traditional AC adapters
  • Pre-installed DC power sockets in each device compartment with brand- & model-specific detachable charging plugs allow a mix of devices in a single cart
  • Plug and Play—no set-up required
  • Integrated central power supply and distribution system
  • Simultaneous charging of all laptops/Chromebooks
  • No timers or switches needed
  • Save up to 85% in energy costs
