Motherboard Inductor Coil Tester Gen 3 – Type-C Powered
Professional Motherboard Coil Tester – 3rd Generation
Whether you're a phone repair technician, electronics engineer, or seasoned maintenance professional, this 3rd Generation Motherboard Inductor Coil Tester is your go-to tool for fast, accurate inductor diagnostics. Powered via Type-C interface, it delivers high-precision detection with strong stability in a compact, handheld form factor.
Key Features
- High-Precision Inductor Detection: Instantly identifies whether an inductor on a powered circuit board is functioning normally or has a fault — no guesswork, no complicated setup.
- Simple LED Indicator: Green indicator light ON = inductor is working normally. Light OFF = inductor is abnormal and requires attention. Diagnose faults in seconds.
- Type-C Power Supply: Convenient, modern Type-C interface for power input. Compatible with standard Type-C chargers (data cable not included).
- Compact & Portable: Measuring just 8 × 2.3 cm and weighing very little, this handheld tool slips easily into a toolkit or pocket — ideal for on-site repairs or workshop use.
- Professional-Grade Build: Constructed from durable plastic and steel components for consistent performance and a long service life in demanding repair environments.
- Easy One-Button Operation: Press the button, bring the sensing tip close to the inductor under test, and read the LED result instantly.

How to Use
- Connect a Type-C power cable to the tester to supply power.
- Power on the motherboard or circuit board under test — testing cannot be performed on an unpowered board.
- Press and hold the button on the tester.
- Bring the sensing tip of the tester close to (but not directly touching) the inductor you wish to test. Note: some inductors are not insulated, so avoid direct contact.
- LED light ON → Inductor is functioning normally.
- LED light OFF → Inductor is abnormal; further inspection or replacement is recommended.
⚠️ Important Note: The circuit board being tested must be powered on during testing. Without power to the board, accurate inductor testing is not possible.

Frequently Asked Questions
Q: Does the motherboard coil tester need batteries to operate?
A: No, this inductor coil tester does not require batteries. It is powered via a Type-C interface. Simply connect a standard Type-C power cable (not included) to the tester and it is ready to use.
Q: Does the circuit board I'm testing need to be powered on?
A: Yes — this is a critical requirement. The motherboard or circuit board under test must be powered on during the testing process. The tester works by detecting the electromagnetic field generated by a functioning inductor; without power to the board, no accurate reading can be obtained.
Q: Can I place the sensing tip directly on the inductor?
A: It is recommended to bring the sensing tip close to the inductor without placing it directly on top. Some inductors are not insulated, and direct contact could interfere with the reading or affect the component. Hover the tip near the inductor for the most accurate result.
Q: Who is this inductor tester designed for?
A: This professional-grade coil tester is designed for phone repair technicians, electronics engineers, PCB repair specialists, and maintenance professionals who need a fast, reliable way to verify inductor functionality on live circuit boards.
