The 12V-24V Dual USB Charger & Battery Capacity Indicator Panel is an all-in-one voltage monitor and power station designed for vehicles and DIY setups. Featuring a 3-digit red numerical voltmeter alongside a multi-segment color battery bar graph, it provides instant updates on your battery’s health while automatically recognizing 12V or 24V systems. Equipped with two integrated 5V USB ports, it allows you to safely charge smartphones and accessories directly from your battery bank, making it a perfect upgrade for electric bikes, golf carts, trucks, RVs, and solar setups.
Full Product Description
The 12V-24V Dual USB Charger, Voltmeter, and Battery Capacity Indicator Panel is a highly versatile power management and monitoring station designed for modern vehicles, marine craft, and DIY solar systems. This multifunction dashboard gauge features a clear, 3-digit red numerical LED display paired with an intuitive 8-segment color battery bar graph (featuring two red low-power warning segments and six green capacity blocks). By connecting directly to your primary battery bank, it provides continuous, real-time diagnostic readouts of your system’s voltage and charge state while doubling as an efficient mobile charging hub.
Equipped with two integrated high-output USB Type-A ports, the module steps down your raw battery voltage to a stable 5V output, allowing you to charge smartphones, tablets, GPS units, and action cameras directly from your dashboard. The smart internal microprocessor automatically recognizes whether it is plugged into a 12V or 24V DC battery system, shifting its internal capacity calculation curves automatically without requiring manual user programming. Its compact, snap-in flush mount chassis makes it an easy, space-saving upgrade for electric bikes, golf carts, trucks, off-road vehicles, camper vans, and portable solar generator arrays.
Key Product Features
- All-in-One Power Station: Combines an accurate digital voltmeter, a multi-segment battery capacity visualizer, and a dual USB phone charger into a single dashboard component.
- Dual 5V Output Charging Ports: Features two standard USB slots capable of distributing stable power to safely recharge consumer electronics on the go.
- Auto-Sensing System Design: Intelligently detects whether the module is connected to a 12V or 24V power source, updating the indicator’s voltage thresholds automatically.
- Reverse Polarity Protection: Onboard circuit defenses shield the internal step-down voltage regulators and microcontroller from burning out if wires are accidentally swapped during installation.
- Snap-In Flush Mounting Bezel: Built with structural side-retaining plastic tabs that secure the meter firmly inside rectangular cutouts without needing external screws.

Wiring and Installation Guide
- Red Wire (Positive Input): Connects to the Positive (+) terminal of your 12V or 24V battery system, or through a switched ignition fuse to turn the display off when the vehicle is parked.
- Black Wire (Negative/Ground): Connects to the Negative (-) terminal of the battery or a secure metal vehicle chassis grounding point.
- CRITICAL NOTICE: Ensure that the input voltage does not exceed 30V DC, as running the module on higher electrical profiles (like 36V or 48V arrays) will instantly overload the integrated step-down components and permanently destroy the charging circuit.
