10-in-1 Digital USB Tester – Voltage, Current, Power, mAh, mWh, Resistance & Temperature

Stop guessing whether your charger or power bank is actually doing its job — the amiciKart 10-in-1 Digital USB Tester gives you live, accurate readings of every critical charging parameter in one pocket-sized device.

This compact tester plugs between any USB source and your device to instantly display 10 real-time measurements: voltage (4–30V), current (0–5A), power (0–150W), accumulated capacity (mAh up to 999,999), energy (mWh), line resistance (up to 999.9Ω), internal temperature (0–80°C), elapsed time (0–99 hours), plus grouping and data logging functions — all on a single bright, easy-to-read display. Works with both USB-A and USB-C ports across phones, laptops, power banks, car chargers, and any USB-powered device.

Whether you're a tech enthusiast verifying your 65W GaN charger's real output, a traveller stress-testing a new power bank's labelled capacity, or simply someone who wants to protect their phone from overheating cables and fake fast-charging claims — this tester pays for itself the first time it exposes a substandard charger. The built-in 0–99 hour timer and 0–9 grouping function make it easy to run and compare multiple charging sessions side by side.
