I made the mistake of buying the 87 watt unit for NZ$120 (wow!), opening the box and finding in fine grey print on the adapter a confusing bunch of different amperage ratings at voltages, but at 5 volts the unit delivers 5 volts at 3 amps (i.e., 3000 mA or milli-amps). To give you an idea of how far this is off from that advertised 87 watt promise, delivering 87 watts at 5 volts it should be delivering __17.4 amps__. Apple's unit is clearly using 87 watts to deliver 15 watts (3 amps at 5 volts) of power. You can check this yourself by using an online [Watts to Amps Calculator|https://www.rapidtables.com/calc/electric/Watt_to_Amp_Calculator.html] or [Amps to Watts Calculator|https://www.rapidtables.com/calc/electric/Amp_to_Watt_Calculator.html].
