What May Be An Overly Complicated And Stupid Question

I have the AC adapters/charging cables for 4 or 5 small electronic devices (including tablets) plugged into a surge protector/powerstrip that has an on/off switch. If I had these various electronics devices plugged into their chargers, but turned off the power to the chargers using the switch on the surge protector/powerstrip, would the fact that the devices are still plugged into the chargers even though there is no power going to the chargers cause the batteries of the tablets and such to discharge faster than if they were unplugged from the chargers (reverse electrical flow?)?
 
Solution
Nope, because like most circuits, electricity can only flow in one direction.
that includes the charging circuit and the power charger.

Shado.
