01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision diagnostics for your 12V system
A compact black instrument that fits easily into a glovebox or workshop drawer, this tester offers immediate clarity on the health of your vehicle's power source. Its matte surface feels substantial yet light, ready for quick checks before a long drive.
Designed for drivers and mechanics alike, it determines whether a battery requires a jump start or replacement while simultaneously checking alternator output. The clear readout removes guesswork from routine maintenance.
02DISPLAY
Four characters for precise voltage reading
The core of the unit is its four-character lighted digital display, which resolves voltage differences down to 0.01 volts. This level of detail distinguishes it from simpler three-character devices, allowing you to spot subtle declines in battery performance early. The screen remains legible in various lighting conditions, ensuring accurate readings whether you are working in a dim garage or under bright daylight.
04SAFETY
Built-in protection for simple operation
Connectivity is straightforward, with protections designed to handle common user errors. Reverse-hookup protection safeguards the internal circuitry if leads are swapped, while over-voltage protection manages inputs outside the standard range. If the voltage drops below 4V, the display shows 'LO'; above 20V, it indicates 'HI'. These features make the tool forgiving and safe for regular use.
PORTABILITY
Lightweight design for easy storage
Weighing just 0.13 kg including its packaging, the tester is exceptionally portable. Its dimensions allow it to slide into tight spaces within a car or toolbox, making it convenient to keep on hand. The black rubber paint finish adds a tactile quality to the grip, ensuring the device stays secure in your hand during testing.

About this product
Easy Operation] – Connect and Go. It provides a quick reading to determine if a vehicle battery needs a jump or replacing and also the alternator output status. Various Colored LEDs indicate the battery or the alternator status.
[Safety Ensured] – Reverse-hookup and Over-voltage protection, making it safe and simple to use. The Digital Voltmeter Testing Range: 4-20V DC. [If the voltage is under 4volts, the screen will display – “LO”; Above 20volts, the screen will display – “HI”]
[High Accuracy] – With a Four-character lighted digital display, the voltage testing accuracy will be close to 0.01volt. [NOTE: Verify the counterfeit with only 3-character display. The accuracy is only 1/10 of ours.]
Micro-processor Controlled. It provides a quick reading to determine if a vehicle battery needs a jump or replacing.
