How to choose a battery charger?
For example, a dry battery is nominally 1.5v, which can make a small light bulb turn on and turn a small motor, but it is impossible for you to want it to light up the lights in your home. If you have a voltmeter, you will find that when it lights up the light bulb, the voltage is still almost 1.5v, and when the small motor is turned, its voltage is much lower, and when you connect it to your home lamp, its voltage is almost the same is zero.
That is to say, when the output capacity of your adapter is less than 1.5a, the voltage is basically within the allowable range of the nominal voltage. It is to convert the AC power supply into a DC power supply with a 7.2v output current less than 1.5a.
