Rolokit DIN Hella USB Charger Adapter — 45W USB‑C PD + 18W QC Dual Port for 12V–24V Bikes with LED Voltmeter

Rolokit DIN Hella Plug to USB Charger Adapter converts European-style motorcycle accessory sockets into dual fast-charging USB ports with a built-in LED voltmeter.

Whether you ride a BMW, Triumph, Ducati or other European motorcycle with a HELLA/DIN accessory outlet, this compact adapter turns the factory power port into a weatherproof charging station. It pairs a 45W USB-C PD port with an 18W USB-A QC 3.0 output, displays battery voltage and charging power on an LED readout and uses a durable aluminum housing and sealed cap for protection against rain and road grit.

How does this adapter fast-charge phones and accessories?

The Rolokit unit supports USB Power Delivery (PD) on the Type-C port up to 45W, supplying higher wattage for modern phones, tablets and USB-C accessories. The USB-A socket uses Quick Charge 3.0 technology to deliver up to 18W to compatible Android devices and accessories.

• 45W USB-C PD 3.0 for rapid charging of phones, tablets and USB-C power banks
• 18W USB-A QC 3.0 for faster charging of older phones and accessories
• Smart IC regulates output to match connected device needs
• Dual ports let two devices charge simultaneously without manual switching

Will the voltmeter protect my bike’s electrical system?

The integrated LED display shows either the system voltage (when idle) or the real-time charging power (when devices are connected), so you can monitor battery condition and load quickly. The charger’s internal circuitry includes protections against over-current, over-charge and overheating to reduce risk to both battery and phone.

• Live voltage readout to check battery health before and after rides
• Real-time wattage display while charging devices
• Built-in safety features for over-current, over-voltage and high temperature
• Smart IC prevents unstable current that could harm devices

Is it durable and weather-resistant enough for motorcycle use?

The housing is crafted from full aluminum alloy for scratch resistance and long service life, while a full-cover rubber cap and precision groove help keep water and dust away from the ports. The voltmeter remains visible through a transparent cover so you can still read diagnostics with the cap closed.

• Aluminum alloy body for durable, road-ready construction
• Rubber protective cap seals ports against rain and dirt
• Transparent cover allows voltmeter viewing with cap closed
• Designed specifically for European-style 12V–24V DIN/HELLA outlets

How do I install it on my motorcycle and what models fit?

Installation is plug-and-play: insert the adapter into the bike’s European-style accessory outlet (DIN/HELLA powerlet), then secure the cap when not in use. It is built for 12V–24V motorcycle accessory sockets commonly found on BMW, Triumph, Ducati and other European models—not car cigarette lighter sockets.

• Simple push-in connection to DIN/HELLA-style powerlets
• Compatible with 12V and 24V motorcycle electrical systems
• Not intended for automotive cigarette-lighter receptacles
• LED readout helps confirm proper installation and battery status

Who is this for: Riders who need reliable onboard charging and quick diagnostics—commuters, tourers and adventure motorcyclists who use smartphones, GPS devices, cameras or power banks while on the road. If you own a European-style DIN accessory socket and want a compact, weather-protected dual USB charging solution with a visible voltmeter, the Rolokit DIN Hella Plug to USB Charger is built for that purpose.
