USB-A 2.0 Multimeter with Dual Output

The DROK USB-A 2.0 Multimeter combines a colour LED display with dual USB 2.0 output ports that support PD and QC 3.0 fast-charge protocols. One button cycles through seven display modes showing voltage, current, power and capacity in various combinations. The unit operates from 3.2 V to 30 V at up to 5 A and includes alarms for over-voltage, under-voltage, over-current and short-circuit conditions.

For testers who need quick protocol checks

Technicians and hobbyists who want an immediate visual check of charger or power-bank output will find the seven-mode display and single-button operation convenient. Builders who require data-line pass-through for sync or debugging should look elsewhere, because the output ports are labelled for charging only. Users needing measurements beyond 30 V or 5 A must select a different instrument.

30 V 5 A measurement ceiling

The tester is specified for input voltages between 3.2 V and 30 V with a current range of 0 A to 5 A, so any source or load outside those limits cannot be measured safely.

Questions about this item

Which display mode shows voltage, current, capacity and power all at once?

Press the single button until the screen reads VA+C+P; that mode combines voltage, current, capacity and power in one view.

What does the 0.6–30 V output range mean when I connect a power bank?

The tester can pass through any voltage between 0.6 V and 30 V, so a 5 V, 9 V, 12 V or 24 V power bank will charge normally while the meter logs the data.

How does the USB-A 2.0 input with PD and QC 3.0 support affect charging speed?

The input negotiates PD or QC 3.0 up to 12 V at 3 A, letting the dual USB 2.0 outputs deliver fast charge rates within the meter’s 5 A current limit.
