Multifunction USB Load Tester
This adjustable discharge module tests chargers, cables, power banks and buck converters while triggering QC 2.0, QC 3.0, AFC and FCP fast-charge protocols. It supports output voltages of 5 V, 9 V, 12 V and 20 V through USB, Micro USB, Type-C and external wiring ports. Engineers and hobbyists use it for equipment ageing tests and battery capacity checks.
35 W Discharge Capacity and Headroom
The unit operates from DC 4.0 V to 25.0 V with a current range of 0.03 A to 5.00 A and a maximum discharging power of 35 W. It comfortably handles typical phone, tablet and laptop chargers but runs out of headroom above 35 W or beyond the 25 V input ceiling. An intelligent cooling fan activates automatically to manage temperature during sustained loads.
USB Interface Practical Limits
Connection relies on standard USB, Micro USB and Type-C ports rated for the specified voltage and current windows. The tester cannot evaluate protocols or power levels outside the listed QC 2.0, QC 3.0, AFC and FCP specifications. Over-voltage, over-current, over-power, low-voltage, over-temperature and anti-reverse protections shut the load down when limits are exceeded.

Questions about this item
Will the 35 W load tester work safely alongside my older USB-A chargers that only deliver 5 V?
Yes, the unit accepts DC 4.0-25.0 V and draws as little as 0.03 A, so legacy 5 V sources stay within its operating window and its anti-reverse, over-voltage and over-current protections guard both sides.
How can I confirm the tester is triggering QC 3.0 or FCP at 9 V after I connect it?
The onboard display shows the negotiated voltage and current in real time; when QC 3.0 or FCP handshake succeeds you will see 9 V and the agreed amperage, while the cooling fan spins up only if internal temperature rises.
Which cables and adapters are included, and what must I source separately?
The box provides USB-A, Micro-USB and USB-C connection ports plus an external wiring terminal block; you only need to supply the charger, power bank or buck converter you intend to test.
