Mobile power working principle
- Dec 01, 2013 -

Mobile power supply is a power storage, boost, charging in one portable device. Storage media generally uses lithium batteries, that lithium batteries is relatively small in size, large capacity, market-Canton, price is moderate, is widely used in digital products. Lithium battery voltages between 2.7-4.2V, voltage drop with drop in power. 2.7-4.2V the charge voltage is not directly to other digital products, because the battery voltage is 2.7-4.2V digital products, is not charged with the potential voltage. So moving is necessary to boost power to the power output system, battery voltage boost 2.7-4.2V to 5V, so that you can charge other digital products, such as mobile phones, MP4, Tablet PCs, PSP and so on.
