Car USB Charger Voltcraft VC-RA401 (VC-15257660) 40W 2x USB‑C PD 3.0, Silver-Black

Voltcraft VC-RA401 is a 40 W car USB charger with two USB-C ports that support USB Power Delivery 3.0. Designed for use in vehicles with 12 V or 24 V sockets, this compact charger provides negotiated fast charging for smartphones, tablets, power banks and other USB-C devices. Its silver-black finish makes it visually neutral while the dual-port layout allows simultaneous charging of two devices with dynamic power allocation.

Advantages

The charger supplies up to 40 W total and implements USB Power Delivery 3.0 to enable fast, negotiated charging profiles that match the requirements of connected devices. Two USB-C ports let you charge two devices at once, with the internal power management distributing output according to device demand. The compact form factor and automotive power compatibility make it suitable for travel and everyday in-car use.

Suitable for

• Charging smartphones and feature phones with USB-C connectors
• Charging tablets and small laptops that accept USB-C PD input
• Recharging power banks and portable battery packs
• Providing in-vehicle charging for passengers on road trips or commuting

When it may not be suitable

This charger is intended for devices that charge via USB-C and support USB Power Delivery. It may not provide optimal performance for devices that require proprietary fast-charge protocols not negotiated via USB PD, or for high-power laptops that require more than the available 40 W total. It is not a direct replacement for dedicated multi-voltage vehicle power inverters or hardwired charging solutions.

Key specifications

• Total output power: 40 W
• Ports: 2 × USB-C
• Charging standard: USB Power Delivery 3.0
• Input compatibility: 12 V / 24 V vehicle socket
• Color: silver-black finish
• Compact form factor for in-vehicle use

How to use

Insert the charger into a standard 12 V or 24 V vehicle socket. Connect one or two USB-C cables between the charger ports and your device(s). The charger will negotiate the appropriate voltage and current with each connected device via USB Power Delivery 3.0 and distribute up to 40 W total output. Remove the charger from the socket when not in use or when the vehicle is turned off for extended periods.

What to consider before purchase

• Confirm your device accepts USB-C charging and supports USB Power Delivery for fast charging.
• Check the power requirements of any laptop or high-capacity device to ensure 40 W total is sufficient.
• Ensure your vehicle has a compatible 12 V or 24 V socket accessible for the charger.
• Use quality USB-C cables rated for PD charging to achieve advertised performance.

Usage recommendations

For best results, use certified USB-C PD cables and connect one high-power device at a time when peak charging speed is required; distributing power between two devices will reduce the maximum available output per port. If you frequently charge high-power laptops, consider a higher-wattage in-car solution.
