Using a multimeter to check whether the output voltage, and the rated output voltage line adapter nominal, can allow for 5% error
if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance
such as an adapter with 5V and 1A, then it is 5V * 1A = 5W, 5V = 5 and 5W 25 square in Europe, select 5 Euro 5 Watt dummy resistance test adapter performance, such as whether overheating after output voltage fluctuation phenomenon
if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance
