HE-Z Technology

[LAPTOPS only] EarthWalk’s patented charging solution, HE-Z, is a game-changer when it comes to saving you time and money. This is a flexible, 2-part system: (1) Each device slot in the cart/lab has one half of the charging cord hard-wired into the cart with an accessible universal DC power socket. (2) Device-specific pigtails (or connectors) fit into the universal, hard-wired power socket. Device-specific connectors fit into the hardwired power sockets, so you can have a mix of device brands in one cart/lab. Easy to upgrade devices, no tools necessary, no adapters needed.  Find a rep to get more info. and determine compatibility with your devices.

Check out the YouTube videos below to see how simple it is to install device-specific “pigtails” into the hard-wired power sockets and how EASILY you can change or update devices without having to update your carts. NOTE: The video examples are shown with our SaverSeries cart.
