SOBMOTO Motorcycle DIN/Hella USB Charger — 12mm Socket Adapter with 36W PD USB-C, 18W QC USB-A, Voltmeter & Switch

The SOBMOTO Motorcycle DIN/Hella USB Charger is a weatherproof, 36W PD3.0 and 18W QC3.0 power adapter engineered to plug into 12mm Hella/DIN sockets on motorcycles, providing fast USB-C and USB-A charging plus a built-in voltmeter and on/off switch.

If you ride a BMW, Ducati, Triumph or other bike equipped with a 12mm Hella/DIN socket, this compact aluminum-alloy charger turns that socket into a dedicated fast-charging port while protecting your battery and devices from the elements. Designed specifically for motorcycle DIN sockets (not car cigarette lighter sockets), the unit combines PD3.0 PPS and QC3.0 smart charging, a readable LED voltmeter, a physical power switch to prevent parasitic drain, and a dustproof rubber cap for all-weather use.

How fast will my phone or GPS charge on this adapter?

The SOBMOTO charger supports PD3.0 (including PPS) on the USB-C port and QC3.0 on the USB-A port, allowing compatible devices to reach high charge rates safely. Actual charging speed depends on your device’s charging protocol and cable quality, but many phones can approach 18–36W charging under the right conditions.

• USB-C: up to 36W PD3.0/PPS for fast charging newer phones and accessories.
• USB-A: up to 18W QC3.0 for legacy devices and accessories.
• Auto-negotiates voltage/current per device to prevent overcurrent.

Will it work on my motorcycle and survive bad weather?

This charger is made to fit 12mm Hella/DIN sockets only; it is not compatible with car cigarette-lighter sockets. The body is aluminum alloy and the socket comes with a full rubber cap and weather-resistant design to resist rain, dust, and vibration common on adventure and touring bikes.

• Precision-fit for 12mm Hella/DIN motorcycle sockets — check socket size first.
• Weatherproof rubber cap protects ports when not in use.
• Rugged construction for vibration and road-condition durability.

What does the voltmeter and built-in switch do for battery management?

The integrated blue LED voltmeter displays your bike’s battery voltage in real time (8V–30V range), giving quick insight into battery health. The physical switch lets you cut power to the USB outputs without unplugging the unit, preventing parasitic drain during long stops or storage.

• Voltmeter reads 8V–30V for instant battery status checks.
• Toggle switch disables power to prevent battery drain when idle.
• Visible LED makes status checks easy while stopped or at night.

Is this safe for my devices and battery long-term?

The charger uses PD3.0 and QC3.0 smart charging standards to match voltage and current to your device’s requirements, reducing the risk of overheating or overcurrent. The aluminum housing and secure fit decrease exposure to vibration and moisture, and the switch plus voltmeter help you avoid draining the motorcycle battery.

• Smart protocols negotiate safe charging profiles automatically.
• Aluminum case dissipates heat during extended charging sessions.
• Switch and voltmeter help you preserve battery life when parked.

Who is this for: Riders who own motorcycles with a 12mm Hella/DIN accessory socket and want a dedicated, durable USB charging solution that provides fast charging, real-time battery voltage readout, and a simple on/off control to prevent parasitic drain. This unit is ideal for adventure riders, commuters, and long-distance tourers using phones, GPS units, heated gear, action cameras, or power banks while on the road. Note: verify your bike’s socket size before purchase — this product is not intended for car cigarette-lighter sockets.
