USB electronic load aging resistance charger charging treasure mobile power test 3A/2A/1A discharge -83745

Product introduction

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

Directions for use

●The USB plug is inserted into the 5V output interface, but cannot be connect

ed 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 1 A.

●Switch S2 is switched to "ON", D3 is ON, the resistor of 2R5 is activated, an

d 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 resist

ance, so the resistance will be hot, pay special attention to not touch the resist

ance with your hands to avoid burns.
