Ask: Battery converter Switching Power Supply, such as turn 5, 7, or 5 turn 1, so the battery and the electrical appliances have no effect?

Answer:Small-capacity battery to switch large capacity battery, so you can make the battery more durable, has no effect on the use of electrical appliances. If the high-capacity battery into a small-capacity battery, but battery life is short some of it.

If you need to use electrical current does not exceed the capacity of the battery-powered, the battery has no effect, but with the short time since the 5th battery capacity is smaller than the 1st half.

Work with the electrical current does not exceed the battery voltage and rated output would not have much impact, more than the rated output of the battery could burn the battery.
