35W USB Load Tester – Adjustable Current, QC2.0/QC3.0 Trigger, Battery Capacity Meter

Stop guessing — know exactly what your charger or power bank is really delivering. The Amicikart 35W USB Load Tester is a precision instrument built for electronics enthusiasts, repair technicians, and power-bank reviewers who need hard numbers, not assumptions.

At its core, this tester lets you apply a controlled, adjustable constant current load (up to 5A, ±1% accuracy) across any USB power source operating between 4V and 25V DC — covering everything from basic 5W phone chargers to high-output 35W laptop power banks. The built-in QC2.0 (5V/9V/12V/20V), QC3.0, AFC9V, and FCP fast-charge trigger protocols mean you can force a charger into its fast-charge mode and measure whether it actually delivers the rated wattage. Real capacity testing, real discharge curves, real data.

Safety is engineered in, not bolted on. An aluminium heat sink paired with an 8000 RPM active cooling fan keeps thermals in check during extended 35W sessions, while a full protection suite — adjustable OVP, OCP, OPP, UVP, and OTP (~80°C) — guards both your tester and the device under test. Dual interfaces (Micro USB + Type-C) cover virtually every modern and legacy USB device. Whether you're a hobbyist validating a new power bank purchase, a technician diagnosing a faulty charger, or a content creator running benchmark tests, this tool pays for itself on the first honest measurement it gives you.
