Welcome use to the second generation of the new upgrade UP LCDV03 tester.

"More than bigger".

This paragraph tester, can test current, voltage, discharge capacity, and perfectly compatible USB data Sync & charging function, most importantly, he also incorporates high-end smart chip fast charging discrimination (CW3002D), with this tester, All chargers, compatibility issues do not exist in your home, you can fast charge, and see accurate results.
The chip is the global patented products protected by intellectual property.

Basic parameters
Input voltage range: 3 ~ 15V
Input current range: 0 ~ 3.5A
Voltage measurement error: 3~ 15V when 1%
Current measurement error: 50 ~ 3500mA time, 1%
Maximum capacity value: 99999mAh
Can store values: 9

Dimensions:64.5*27.5*15.5mm

More details, please refer to the instructions.

This product than the previous generation, with more significant progress,

adds the following features:

1, LCD big screen: Size 20 * 14mm, with blue backlight
2, 20AWG USB Cable input, low current and voltage loss (actual test, Micro USB input voltage loss is higher than USB Cable input voltage loss 0.1V)
3, over-current, over-voltage, low voltage alarm with buzzer alarm
4, overcurrent, overvoltage, power protection
5, Samsung mobile phone, tablet, IPAD large current adaptive function (independent CW3002D chip) can be compatible with most of the mobile tablet currently achieve maximum charging current (in the context of sufficient power charger)
6, dual USB output function (one USB data Sync & charging function, one is a universal USB adapter quick charge function)

Because, Power Bank and mobile phones, in use, the voltage and current is not a stable value. If you need more accurate results, you need a load resistor with a switch. You can purchase a separate $ 2
