    小米最开始推出的是69元10400mah移动电源,虽然电量大但体积也大,不方便携带,里面有四节18650的电池,后来推出5200mah的移动电源,体积小了很多,里面有2颗18650的电池,按这个节凑,小米是不是会推出更小体积,只有1节18650电池的移动电源呢?这样更方便携带,而且18650电池也有3000多mah的,足够满足一次手机充电需要了,大家觉得呢?

    意义不大,还要将升压过程中的损耗也计算在内,实际可以用的容量不多,雷布斯不傻

    很简单,做个算术题:

    一节3400mAh的18650

    USB升压电路效率80%

    那么剩下可用的容量理论值=3400mAh X 0.8 = 2720mAh

    再加上充电线的线阻损耗、电量指示LED的耗电量

    可用电量能有2700mAh就不错了

    5200mAh的卖49,那这玩意如果出了,该卖多少钱?

    我倒是怀疑雷布斯是否会朝着太阳能或手摇方面打主意

    把5200 里面多余的填充塑胶去掉做个小的就行了

    现在那个5200根本就是按照3节电池空间来做的
