USB Resistor Electronic Load w/Switch Adjustable 3 Current 5V Resistance Tester

Product Introduction

According to Ohm's law (voltage/resistance = output current) design of USB discharge load device, through the above two switches control loading different power resistance value, can obtain three current aging, respectively 1A/2A/3A. Board with different resistance of the corresponding indicator light and power indicator light, clear and clear. Easy to use, can be aging test power bank mobile power charger.

Directions for use

The USB plug is inserted into the 5V output interface, but cannot be connected to the quick charge interface above 5V due to the resistance value and the maximum power limit of the resistor.

Power indicator D1 is on.

Switch S1 is switched to "ON", D2 lights up, the resistor of 4R7 is activated, and the current is about 1A.

Switch S2 is switched to "ON", D3 is ON, the resistor of 2R5 is activated, and the current is about 2A.

If S1 and S2 are switched to "ON" at the same time, the two resistors operate with a current of about 3A.

Note:

Because a large amount of current is consumed through the heating of the resistance, so the resistance will be hot, pay special attention to not touch the resistance with your hands to avoid burns.

Functional Features

5V USB test

Three gears available

Indicator status is displayed

USB plug is inserted into the interface of 5V output. Due to the limitation of resistance value and maximum power of resistance, it can not be connected to the interface of quick charge above 5V.

After the system is powered on, power indicator D1 is on.

Switch S1 is switched to "ON" D2 to light up, the resistor of 4R7 is activated, and the current is about 1A.

Switch S2 switches to "ON", D3 lights up, and the resistor of 2R5 comes into operation with a current of about 2A.

If S1 and S2 are switched to "ON" at the same time, the two resistors operate with a current of about 3A.
