Details: Description The product is designed according to the principle of ohm's law and through the resistor in parallel and two different switches, the module can provide 2 kinds of resistance for USB power input, when all the switch opens, is 2.2 ohm/10W, 4.7 ohm/5W, 2 kinds of resistance in parallel at the same time, in 5V voltage almost can produce 2A discharge current. The actual current size, please according to ohm's law: I = U/R Resistor in parallel calculation formula: R=1/(1/R1+1/R2+.+1/Rn) K1=4.7Ohm/10W , K2=2.2Ohm/10W When using this discharge resistor the element reaches high temperature and hence handle it carefully, do not touch with bare hands. Also, please do not put flammable substances nearby when using it, and avoid direct contact with the heat resistance of the desktop, so as not to scorch the desktop. It is normal when welding resistance may occur heated white smoke or odor phenomenon. New products can freely be switched with a switch, very convenient and easy to use. USB load resistance, is mainly to do discharge test, if the charger or mobile power supply output current is 2A, load meter power is 5V * 2A = 10W, if the output current is 1A, then the power load is 5V * 1A = 5W.
