Common sense of transformer plug
Indoor electricity is 110V
But when electrical products are not 110V
it will there be a dedicated transformer plug
What should you do when you can't find the plug?
at this time
Have transformer plugs for other electrical appliances on hand
Can it also be used?
The following is a little common sense to judge
Input: AC 110V~120V 60Hz
Output: DC 9V 300mA
The main thing to look at is the output.
Check the specifications of the appliance.
The 9V displayed on the output represents the voltage, and the output voltage of the transformer cannot be greater than the input voltage of the appliance.
For example, if the input voltage of an electrical appliance is 12V, then the output voltage of the transformer must be <12V to be used.
However, when the voltage is too low, it may be fully charged, but the appliance cannot be used.
If the output shows mA, it means this is a rechargeable battery,
For example, 300mA means that the battery capacity is 300mA.
Assuming that the battery capacity of the electrical appliance is 600mA, then using a 300mA transformer will not be fully charged. Use a transformer greater than 600mA, but if the mA is too large, the battery may be damaged. (Depending on the brand, some brands are relatively poor, charging Overcharge will be broken, most batteries can be overcharged, but often overcharged will shorten the battery life)
变压器插头小常识
室内用电为110V
但电器产品并非110V的时候
就会附有一个专用的变压器插头
当你找不到该插头的时候，怎么办呢？
这个时候
手边有其他电器的变压器插头
是不是也可以用呢？
以下是判断的小常识
输入：AC 110V〜120V 60Hz
输出：DC 9V 300mA
主要看的是输出。
查看电器的规格。
输出所显示的9V代表着电压，变压器的输出电压不可以大于电器的输入电压。
例如电器的输入电压是12V，那变压器的输出电压须<12V，便可以使用。
但是，当电压太小的时候，有可能充饱电，电器却无法使用。
如果输出有显示mA，代表这个是充电电池，
例如300mA，代表着电池容量是300mA。
假设电器的电池容量是600mA，那使用300mA的变压器，会充不饱电，要使用大于600mA的变压器，但mA太大也有可能使电池坏掉。 （要看品牌，有的品牌比较差，充电过量会坏掉，大多数的电池都是可以充电过量的，但时常充电过量，会减短电池的寿命）
