Features:
This dual USB meter displays both voltage and current during USB charging or discharging on the same screen, and can alternately or individually display capacity and power.
It uses a USB extension cable input with output interfaces at both ends for easy use.
This power meter is manufactured using high-quality SMT for surface mount technology, stable and reliable quality.
It features a built-in intelligent load identification IC that automatically matches high-current loads.

Input Voltage Test
Test Voltage: 3.20 - 30.0V (automatic decimal point switching); Resolution: 0.01V below 10V; 0.1V above 10V;
Test Current: 0.00 - 5.00A (maximum up to 10A, but cannot operate for extended periods); Resolution: 0.01A;
Capacity Test: 0-99999 mAh (i.e., 99,999 A/H).
Capacity Accumulation: Can continuously accumulate capacity for N charging cycles.
Capacity Display
1. When no USB device is connected, the capacity displayed after powering on is the previously accumulated capacity, with a power-off memory function.
2. After clearing the capacity, the displayed capacity is the current capacity. The accumulated current is the capacity of N charging or discharging cycles.
3. The capacity display can be switched via buttons.
Capacity Clear
1. When powering off and then powering on again for charging, the previously accumulated capacity will be cleared. 2. Clears after flashing twice. 2. Press and hold the button; the accumulated capacity will flash twice and then clear.
Power test range: 0.00 - 9.99 - 99.9 W, decimal point automatically moves. Overvoltage alarm: When voltage ≥ 5.6 V, the voltage decimal point flashes rapidly.
Undervoltage alarm: When voltage ≤ 4.4 V, the voltage decimal point flashes slowly.
Overcurrent alarm: When current ≥ 3 A, the current decimal point flashes rapidly.
Short circuit alarm: The current decimal point flashes rapidly.
Button: 1 button switches between 7 different display modes: VA only, C only, P only, VA+C, VA+P, C+P, VA+C+P, VA+C+P. Press and hold this button to clear the accumulated capacity. When an alarm message is received, press and hold this button to cancel the alarm notification function.
