Charging Systems

Integrated AC Charging (model EXPR-20C-AC)
For budget-minded consumers, eXpress labs can be configured with 20 AC Outlets for use with each device’s AC adapter. System is configured with a 15 Amp circuit breaker. NOTE: Simultaneously charging 20 higher powered devices could possibly overload the 15 Amp circuit breaker. Depending on the electrical draw of the devices you are deploying, it may be recommended to upgrade to a managed power system. Consult your EarthWalk solution specialist for details.

HE-Z – High Efficiency Charging System (model EXPR-20C-HE)
This patented system provides the most energy-efficient and easy approach to charging groups of devices—no AC adapters needed! EarthWalk’s High Efficiency (HE) charging integrates a central power supply and control circuit board system to distribute simultaneous power to every device with up to 85% more energy efficiency than charging with AC Adapters. HE-Z charging cables can be easily swapped when devices are changed or updated and this system also allows multiple brands of devices to be stored and charged in one cart/station/locker.
