Let me calculate the wattage required for charging a pair of 2200mAh 3s together at 1C. I purchased a cheap charger on Amazon about 30 which only lasted about 3 months. For example if the current is 3 amps 3A and the voltage is 110V you multiply 3 by 110 to get 330W watts.

Take these two figures and multiply them and youll find out the adapters maximum wattage. In other words power is the product of current multiplied by voltage. All you need to do is look for the adapters maximum voltage and amps.

How to Calculate the Wattage of an AC Adapter.
