Stop guessing whether your charger and cable are performing properly. This compact tester displays real-time charging data between a USB source and connected device. It suits phone owners, technicians and hobbyists checking chargers, cables and power banks. QC 2.0 and QC 3.0 support makes it useful for standard and quick-charge setups.
Key Features

- Seller-stated 4–30V operating range.
- Plug-and-play design needs no separate power supply.
- Clear digital screen keeps key measurements visible.

Why Choose Our ChargeCheck USB Meter
Unlike voltage-only testers, this USB current meter shows multiple charging values in one portable device. It helps identify weak cables, underperforming adapters and inconsistent USB output without a full-size multimeter. QC compatibility does not guarantee every charger protocol or charging speed.
Perfect For
USB wall chargers, car adapters, power banks, charging cables, phones, tablets and electronics workbenches.
How to Use
Insert the tester between the USB power source and charging cable, then connect the device. Allow a complete charge cycle when checking capacity. Stay within the rated voltage and current, keep it dry and never connect it directly to mains electricity.
Test Your Charging Setup
Add this USB capacity tester to your toolkit and check performance with less guesswork.
