This table exhibits Each individual charger's capability to produce the rated power, depending on my measurements of utmost electricity. Whilst most chargers fulfill or exceed the facility rating, there are some exceptions.

This is fantastic. I like that you simply did the actual measurements right here. This's an amazing object lesson for sustainable electronics designers / engineers.

For this charger, the upper line isn't going to get really far, demonstrating that this charger isn't going to output Considerably existing. My suspicion is usually that it had been only examined with 240 volts so it performs improperly with one hundred twenty volts, Though the label states it's going to take one hundred to 240 volts.
