5V 10W 2 Switch USB Charging Current Detector Tester Discharge Aging Board tại Lotte Market

Giới thiệu 5V 10W 2 Switch USB Charging Current Detector Tester Discharge Aging Board tại Lotte Market

Description:
A designed according to the principle of ohm's law and through the resistor in parallel through a different switch, can produce 3 kinds of resistance of a new USB electronic load resistance discharge, when all the switch opens, is 2.2 ohm/10W, 4.7 ohm/10W, 2 kinds of resistance in parallel at the same time, in 5V voltage almost can produce 3A discharge current. 　
It can test whether the output current of mobile power charging treasure, mobile phone charger, USB power supply, etc. is up to standard.
The aging test can be performed on the mobile power supply and the USB power adapter. When the aging test is discharged, the resistance will be hot, and the temperature is around 80~85 °C. Please pay attention to anti-scalding.
Because of the special nature of the heating resistor, the phenomenon of odor will occur after the initial use of the power for a period of time, because the exterior paint is subjected to high temperature baking to produce an odor phenomenon, and completely disappears after a period of use. This phenomenon will inevitably occur. It is normal. You don't have to worry about the load tester being damaged. Please feel free to use it.
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
