Whether or not the right solar charger for you will need an internal battery will be determined by the type of devices you intend to charge and your intended use.Smaller devices,such as cell phones or digital music devices might run fine directly from the sun.However,larger devices may require a battery because of the power needed.While solar chargers without internal batteries are cheaper,one important consideration to note is that if the sun is not available when you intend to use the device,it will not work.Consequently,having an internal battery is much more convenient as the device can be run at any time,regardless of the level of sunlight.
对于你而言，一个太阳能充电器是否需要一个内装电池将取决于你用来充电设备型号以及你的使用目的。较小的设备如手机或数码音乐设备可以直接充电且效果较好。然而，大一点的设备因为电量需要或许需要一个电池。没有内装电池的太阳能充电器较便宜，要值得重点注意的是如果你想在没有太阳时充电，该充电器可不会正常工作。因此，有一个内装电池会使用起来更为方便因为该设备可以随时工作，无论太阳光水平怎样。
