Function characteristics:

1. 8192 pixels HD display
2. D+ D- Voltage Tester
3. Memory power time data such as power
4. The single monitoring shows charging voltage, current, power, power WH,mAH, charging time and other information;
5. USB is the copper pin and a low resistance in sampling technology, access after almost does not affect the charging speed
6. Wide voltage from 3.30 V to 32.7 V
7. Low and lower power since the < 0.003 A < 3mA 
   3.30V~32.7V / 0.00A~5.10A / 0 ~ 299.999W / 0 ~ 999999 WH / 0 ~ 999999 mAH / 0~+80 / 0~999 ohm / 999H 59M 59S / D+ D- Voltage 0.000V ~ 2.999 V / Since the power flow: < 0.003 A
