You may safely use the ZEN15 Power Switch with:
DO NOT connect any of the following:
The ZEN15 Power Switch is incompatible with 220V appliances in general. Connecting these types of appliances will damage the Power Switch immediately or over time. This can also cause the connected appliance to malfunction.
And in the case of phone and battery chargers, impulse loads like these don't draw enough power at stand-by when ON for the electronic part of the ZEN15 Power Switch to function correctly. While most likely nothing will happen if the ZEN15 Power Switch is used with a charger, in the long run it's possible that the electronics in the switch will fail.
