Full charge off automatically, to avoid overcharging.
The UPM can be used to measure the output performance of any USB charging adapters,PC USB ,Car USB
Specifications: Working voltage range: 4.5 ~ 5.7V DC
Working current range: 0 ~ 3A
Voltage precision: +/-0.5%, Resolution: 0.01V
Current precision: +/-1%, Resolution:0.01A
Current sensing resistor: 10mohm
Standby current: 20mA
Low power MCU with 10bit ADC
Note:
Connect the UPM into the host machine (Home USB charging adapter,Car USB charger, PC USB port,portable power bank,etc.)
If the input voltage is out of the range of 4.5~5.7V DC ,the UPM will alarm ""Be Be"" & voltage value will blink.
Blue LED ON/OFF - Output ON/OFF
Protection : Over 5.7V or over 3A, No output.
Setting:
Self-close down function & End Level setting.
UPM detect the full charging according to End Level(EL).Please set the EL according to different devices.
If the current is cut automatically & device is not full charged,Please adjust the EL value builds.
Hold the button 3 seconds to enter the setting.Quick press the button to cycle through the value :10.20.30.40.60.off (Default value is 30).
Save & exit with beep if no action within 5 seconds.
OFF - Close the function.
