Chaos mobile power market, many pretend to play the Yu copycat products, only the brand manufacturers to produce the normal product quality and customer service is guaranteed, because of the particularity of lithium battery, its decision cannot be over charge, over discharge, and short circuit, it is easy to cause the battery explosion! So dear before the choice of such products to identify Features: lasting power. This product adopts the high capacity of lithium battery, can be said to be the leading products in the mobile power supply, power and durability, is necessary to travel! Characteristics of two: no memory effect (very important) memory effect is an effect because of the use of the battery cell contents to produce crystalline. Generally only happens in nickel cadmium batteries, nickel metal hydride battery lithium battery less, no such phenomenon. The reason is due to charge and discharge the battery part repeat incomplete caused by the battery will be temporary capacity decreases, leading to call time. Characteristics of three: multiple protection version protection plate is used to provide electronic circuit board to protect the lithium electric core, it is usually made of a IC control, a MOSFET tube and the surrounding components. Due to the particularity of lithium-ion electrical core, its decision cannot be overshoot, over discharge, over current and short circuit, so each lithium ion batteries require a protective plate provides protection for the above!
