a simpler trick would be to go to a garage sale and pick up an older model that doesn't have this feature.

This feature is just like in an alternator in a car. The bridge rectifier is set up on a switch circuit that senses voltage and turns on and off the circuit. This type of charger is known as a switching power supply.

To get around this problem, you would have to know exactly what you were doing with electronics. Not an easy task for someone that has no background.

Look on craigslist for an older model or put an want add out for one would be my suggestion. You want a continuous supply, not a switching supply.
