ECO Safe Charge™ Power Management System by LocknCharge

June 22, 2024

ECO Safe Charge Functions

The remote-controlled ECO Safe Charge™ Power Management System has the capability to charge multiple laptops and power other electrical equipment safely and efficiently. ECO Safe Charge is essential when a high capacity Charging Station or Charging Cart needs to simultaneously charge a large number of devices.

The intelligent ECO Safe Charge™ Power Management System provides four essential functions:


sequentially stages power to each group of outlets, reducing the possibility of a momentary electrical overload when multiple laptops are first powered on. This mode will work up to 1500 Watts.


Sequentially stages power to each group of outlets but automatically turns the power off after a selected time has elapsed. Use this mode to quickly charge all laptops if it is permissible to charge them together without causing a general electrical overload.


Individually powers each group of outlets at a time for the duration selected then automatically turns the power off before applying power to the next group of outlets until it has cycled through all groups of outlets. Use this mode to prevent a general electrical overload if all the laptops require more power than is permitted to be supplied to all laptops together. If your devices require more than 1500 Watts, use ECO-TIMER-CYCLE to stage the availability of power to avoid overload.


This function turns off all outlets.

Benefits of ECO Safe Charge

  • Reduces the possibility of blowing a circuit when a Cart or Station filled with devices is plugged into a single outlet.
  • The ECO-TIMER™ functions can reduce your energy consumption, reduce carbon emissions, extend the life of device batteries and reduce your power bills.

How to Adjust LocknCharge ECO Safe Charge Settings for Devices with Higher Power Draw

If you have LocknCharge products equipped with the ECO Safe Charger, such as the Joey Carts, Carrier Carts, or Revolution 32 Cabinets, and are upgrading your devices to ones that can handle higher capacity power, you may need to consider changing how you charge devices inside your LocknCharge products. 

In the past, it's possible you used the Eco-Timer All setting to charge all of your devices simultaneously. However, with newer devices, we recommend using the Eco-Timer-Cycle setting to cycle power from one group of devices to another – ensuring they all receive the maximum power they can, without tripping the circuit breaker.

Understanding AMPS

A typical home circuit is 15 amps, which equates to 1875 watts. A commercial circuit can carry 20 amps, which equates to 2400 watts.

By using a LocknCharge product featuring ECO Safe Charge, it's possible to charge up to 1500 watts in SAFE-ON mode. You may experience challenges if all of your devices are fully-depleted, if you're charging 40 devices that are supplied with more than 45-watt power supplies, or if the same circuit is pulling power to charge other electronics in addition to the Cart.

The reason for these challenges is that the devices will pull too much current for the ECO Safe Charge, and the circuit breaker will open. To fix this issue, simply change the charging mode to 3-hour ECO-TIMER-CYCLE to get the devices up and charging. Once the devices have some charge in them, the Cart should be able to continue in the ECO-TIMER-ALL mode to keep them charged during the day.

Setting Up ECO Safe Charge


Any LocknCharge products featuring ECO Safe Charge or ECO Smart Charge that were manufactured on or before August 13, 2021 have max current of 15A. Products manufactured after this date have a max current of 12A. This change is in compliance with UL 62368-1 standard.
