Dual USB Output

• OUTPUT I (Dual Function - Device Charging and Data Transfer)
The charging current, in this case, is determined by compatibility.
You can view the voltage and current values at the same time.

• OUTPUT II (Device Charging Only)
The Built-in intelligent charging control IC matches the most appropriate and safest current for your devices automatically. It is used mainly for Non-original Chargers, but it is suitable for Original Chargers as well.
This universal usb gadget is suitable for most of the mobile phones, mobile power, tablet PCs and other USB devices, like BC1.2, YT/D1591-2009 and non-BC1.2 (including iPad, iPhone and Samsung Galaxy).

• MEASURING RANGE: Voltage 3.20 - 15.0V, Current: 0.00 -3.00A, Accuracy: +/- 1%
• 7 Modes USB Monitor - Press the button to switch among 7 different modes: VA(Voltage and Ampere), C(Capacity), P(Power), VA+C, VA+P, C+P, VA+C+P. Can be used to measure voltage, current, capacity and power.
• Dual Color Led - Dual LED display with Red and Blue color, which is bright and easy to read.
• Dual USB Output - USB Output I can be used for device charging and data transfer. The Output II can be used for charging your mobile phones, tablet PCs, iPad and other USB devices.
• Multifunction - Can be used for capacitance checking, capacitance clear, over voltage and under voltage alarm, over-current, and short circuit alarm. You can easily test the power/quality of the chargers and USB cables.
