携小电会员是什么

　　携小电会员是针对长期出差的客人提供的一种增值服务，适合对充电频率较高的客人，如做直播住酒店，无时无刻都要充电的客人。携小电充电宝方便携带，体积较小，兼容性强，适用于市面上所有的手机。

　　充电宝的工作原理：

　　充电宝是一个集储电，升压，充电管理于一体的便携式设备。储电介质一般采用锂电电芯，因为锂电电芯体积相对小巧，容量大，市场流通广，价格适中，被广泛用于数码产品。锂电的电压在2.7-4.2V 之间，电压随着电量的下降而下降。而2.7-4.2V的电压是不能直接给其它数码产品充电的，因为数码产品的锂电电压也是2.7-4.2V,同电位的电压之间是不能充电的。所以移动电源向外输出电能是必须要有升压系统，把2.7-4.2V 的锂电电压升压到5V，这样就可以给其它数码产品充电了，如手机、MP4、平板电脑、PSP等。

　　Membership with small electricity is a value-added service provided for long-term business trip guests. It is suitable for guests with high charging frequency, such as those who live in a hotel and need to charge all the time. It is easy to carry, small in size, and strong in compatibility. It is suitable for all mobile phones on the market.

　　How the power bank works:

　　A power bank is a portable device that integrates power storage, boosting, and charging management. Lithium battery cells are generally used as storage media, because lithium battery cells are relatively small in size, large in capacity, widely circulated in the market and moderate in price, and are widely used in digital products. The voltage of the lithium battery is between 2.7-4.2V, and the voltage decreases with the decrease of the power. The voltage of 2.7-4.2V cannot directly charge other digital products, because the lithium battery voltage of digital products is also 2.7-4.2V, and it cannot be charged between voltages of the same potential. Therefore, the mobile power supply must have a boost system to output power to the outside, and the 2.7-4.2V lithium battery voltage can be boosted to 5V, so that other digital products can be charged, such as mobile phones, MP4, tablet computers, PSP and so on.
