Description

KWS‑V20/V21 USB Voltage Current Tester

📌 Product Overview The KWS‑V20/V21 USB voltage and current tester is a portable digital power detection instrument for USB charging equipment. It can synchronously monitor real‑time voltage, current, charging time and accumulated battery capacity (mAh). It is equipped with a clear digital display screen and an independent reset button to clear timing and capacity records. Two optional styles are available: V20 with a blue transparent housing and V21 with a black transparent housing. Plug‑and‑play design without extra driver software, which is widely used for performance testing of mobile phone chargers, power banks, car chargers and various USB power adapters. ✨ Core Features

Multi‑group data synchronous display: voltage, current, charging time and accumulated capacity value.
Wide measurement range: test voltage 4‑20V, test current 0‑3A.
High‑precision resolution: voltage resolution 0.01V, current resolution 0.01A, measurement accuracy ±1%.
Independent RESET key for one‑click clearing of timing and capacity data.
Transparent shell design for observing the internal circuit structure.
No external power supply or driver required, plug‑and‑play for quick testing.
