DIY Rechargeable Multimeter: Type-C & LED Upgrade

Enhance the functionality of your multimeter by converting it into a rechargeable device. If you frequently forget to turn off your multimeter or encounter persistent low voltage warnings, follow these steps for an efficient upgrade:

Identify a 1000mA battery and secure a fitting casing.

Acquire a charging board, a booster board, a small switch, and a Type-C socket.

Opt for a commonly used Type-C socket for the charging dock to enhance user convenience.

Connect the power switch to the booster circuit, with the switch thoughtfully positioned on the top panel.

Apply hot glue to the LED on the charging board and the 10A jack, ensuring that the emitted light effectively communicates the charging status.

Monitor the charging process with a red LED, transitioning to a blue hue upon reaching full charge.

To address concerns about low voltage displays and potential abrupt power interruptions due to protective circuits, consider incorporating a phone battery socket. This allows for seamless battery replacement when needed. Additionally, the Type-C socket's convenience aligns with modern mobile devices, equipped with power bank functionality. With a simple plug-in approach using a charging cable, your converted multimeter remains ready for use at all times. Upgrade your equipment for enhanced efficiency and worry-free operation.
