Car Charger with Display Dual USB QC2.0/3.0 FCP Fast Charging Voltage and Current Measurement

This car charger with display offers a practical solution for drivers who want to monitor their vehicle's electrical system while keeping devices charged. The integrated LCD screen shows real-time voltage and current readings, allowing you to check battery health and charging performance at a glance. With support for multiple fast-charging protocols including Qualcomm Quick Charge 2.0/3.0 and Huawei FCP, this charger delivers optimised power to compatible devices automatically. The splash screen alarm provides an early warning when voltage drops below 11.4V, helping you avoid unexpected battery failures during journeys.

Features and Construction

Built with functional design and practical monitoring capabilities, this charger combines dual USB outputs with an informative display. The PC+ABS construction ensures durability for everyday use in the vehicle environment.

Material and Build

Constructed from PC+ABS material, the charger housing offers a balance of strength and lightweight design. The black finish blends with most vehicle interiors, and the compact form factor fits standard 12V-24V DC sockets without protruding excessively.

Size and Practical Fit

Designed as a standard car charger size, it fits into most vehicle cigarette lighter or accessory sockets. The dual USB ports sit side by side, allowing simultaneous charging of two devices. The built-in display is positioned for easy visibility from the driver's seat.

Charging and Monitoring Capabilities

This charger provides both fast and standard charging options alongside real-time electrical monitoring. The intelligent protocol detection ensures compatible devices receive appropriate power levels.

Fast Charging Protocols

Port 1 supports Qualcomm Quick Charge 2.0/3.0 and Huawei FCP protocols, automatically selecting the correct protocol for connected devices. Output varies from 3.6V to 12V depending on device requirements, with maximum current of 3A. This enables faster charging for compatible smartphones and tablets.

Standard USB Output

Port 2 delivers a steady 5V/2.4A output suitable for charging devices that do not support fast charging protocols. This port is ideal for older devices, GPS units, or other accessories requiring standard USB power.

Voltage and Current Display

The LCD screen shows voltage measurements between 5V and 30V, and current measurements from 0A to 3.0A. This allows monitoring of vehicle battery voltage when the engine is off, or alternator output when running. The current display shows real-time charging draw from connected devices.

Safety and Practical Benefits

Built-in monitoring features provide useful information about your vehicle's electrical health while charging devices. The high conversion efficiency reduces power loss during use.

Low-Voltage Alarm

When voltage drops below 11.4V, the display triggers a splash screen alarm. This feature alerts drivers to potential battery drain or charging system issues before they become problematic, particularly useful for overnight parking or extended accessory use.

Efficient Power Conversion

With a conversion efficiency of 95%, less energy is wasted as heat during the charging process. This contributes to more effective charging and reduced strain on the vehicle's electrical system compared to less efficient chargers.

Why Choose This Product

This car charger combines dual-device charging capability with practical vehicle monitoring in a single unit. The automatic protocol detection works with modern smartphones, while the standard port accommodates a wider range of devices. The voltage alarm adds safety value for those who want to keep track of battery condition.
