USB tester for chargers and power banks

The Hetai Tech KWS-V30 measures DC voltage from 4 to 30 V and current up to 6.5 A, capturing power to 195 W. It suits technicians and enthusiasts who need to verify charger output, power-bank capacity or cable losses without a bench supply.

6-in-1 IPS display with wide viewing angle

A 160° IPS colour screen shows voltage, current, elapsed time, power, milliampere-hours to 99999 and watt-hours to 999 in one view. The smart chip upgrades sampling accuracy so the readings reflect real charger behaviour under load.

Compact plug-and-play with no drivers

The unit measures 60 by 26 by 13 mm and connects in-line between a USB source and the device under test. Minimum measurable current is 0.02 A, so very low-power devices may not register. Timing stops at 990 hours, limiting very long discharge tests.

Questions about this item

Will the 160° IPS display need recalibration or replacement after long-term use?

The 160° IPS screen is a fixed component with no user-serviceable parts; no recalibration or replacement is expected under normal operation.

What limit will be reached first when testing a 120 W charger continuously?

The 6.5 A current ceiling will be hit before the 195 W power ceiling when a 120 W charger runs at its maximum output.

How much heat does the tester add to the cable run during all-day monitoring?

The unit draws only the 0.02 A minimum test current for its own operation, so added heat is negligible during continuous use.
