USB Electronic Load Aging Resistance Charger 3A/2A/1A Discharge Charging Bank Mobile Power Test with Adjustable Switch

Overview According to Ohm s law voltage resistance value output current the USB discharge load is designed to load different power resistance values ​​through the two switches above and 3 types of current aging can be obtained which are 1A 2A 3A Onboard Corresponding indicator lights and power indicator lights with different resistances are clear It is easy to use and can be used for aging test of power bank mobile power charger Features 1 5V USB test2 Three gears can be selected3 The indicator shows the status4 Hardware introduction and description5 Board size 67 22mm6 Weight 14gInstructions for use 1 After power on the power indicator D1 will light up 2 The USB plug is plugged into the 5V output interface Because of the resistance value and the maximum power limit of the resistance it cannot be connected to the fast charging interface above 5V 3 Switch S1 to the ON gear D2 lights up the 4R7 resistor starts to work and the current is about 1A 4 Switch S2 to the ON gear D3 lights up the 2R5 resistor starts to work and the current is about 2A 5 When S1 and S2 are set to the ON gear at the same time the two resistors work and the current is about 3A Notice Because a large amount of current is consumed by the working heat of the resistor the resistor will get hot Take special care not to touch the resistor with your hands to avoid burns Package included 1 x Power Test Module
