About
LED Status Indicators - Clear indicator lamps show working status at a glance, making it simple to confirm discharge mode and resistor selection. The onboard LEDs illuminate in distinct patterns to show which current path is active, so you instantly see if set to 1A, 2A, or 3A. This visual feedback
Versatile USB Testing - Works with chargers, mobile packs, and electronic gadgets, offering accurate current output checks via plug-and-play setup. Just insert into any 5V port and start measuring—no drivers required. Use it to verify wall adapters, car chargers, or DIY battery packs before
Compact & Portable Tool - Small lightweight form factor slips easily into a pocket, ideal for on-the-go electronics diagnostics and field testing. At just a few grams, you can carry it in your toolbag without adding bulk. Ideal for technicians working at different sites, or travelers needing a quick
Consistent PCB Construction - Sturdy printed circuit board resists cold joints and tear, ensuring stable repeatable performance for frequent testing. Top-notch solder joints and sturdy traces avoid intermittent failures, giving consistent readings every time. Rigorous quality control ensures it
USB PORT: Enables easy operation, just plug and play. Also very convenient to carry with small size and light weight.
Product Description
Tired of guessing whether your charger or bank really delivers the rated current, concerned that weak output damages your devices over time? Imagine plugging in a simple tester and instantly seeing exactly how many amps are flowing, with no confusion or expensive lab equipment. This USB Load Tester solves it with an adjustable resistor that creates precise 1A, 2A, or 3A loads, paired with bright LED indicators to show the active setting clearly — just flip the switches and read the results. Made of a sturdy printed circuit board with solid craftsmanship, this compact module plugs directly into any 5V USB port, making it ideal for electronics enthusiasts, repair techs, and anyone who values consistent current.Item Type: USB Load TesterMaterial: Printed Circuit BoardWorking Voltage: DC 5V (USB current supply)Function: A USB discharge load tester designed according to Ohm's law (voltage/resistor value = output current), through the two switches above to control load different current resistor values, and obtain 3 kinds of currents, respectively 1A, 2A and 3A. Onboard corresponding different resistor indicator lamps and current indicator lamps are very clear. Simple to use, you can test the bank and mobile charger. Applicable Scenarios: For electronic equipment, bank, mobile, charger. Package List：2 x USB Load TesterNote:1. Do not use the product in a electrostatic environment, otherwise static electricity will damage the electronic components; 2. The USB plug is plugged into the 5V output interface. Because of the resistor value and the maximum current limit of the resistor, it cannot be connected to the fast charging interface above 5V.
