10A Black USB DC-DC Converter for Electric Scooters

The 10A Black USB Transverter (2289) is a high-performance DC-DC power converter engineered to step down high-voltage traction battery power (36V to 72V DC) into a stable, regulated 12V output. Built specifically for electric scooters, e-bikes, and light electric vehicles, this transverter powers critical auxiliary electrical components such as LED headlights, tail lights, horn units, and instrument display panels.

Featuring an integrated 5V USB charging port (1A output), it also provides a convenient power source to charge mobile phones, GPS navigation units, and action cameras on the go. Encased in a sleek, durable black housing, it ensures efficient power conversion (approx. 93% efficiency) with built-in safeguards against over-voltage, over-current, and short-circuiting.

Key Features

Wide Input Voltage Range: Compatible with 36V, 48V, 60V, and 72V DC main battery packs, making it versatile across multiple electric two-wheeler configurations.

Stable 12V Output: Delivers a consistent 12V DC output with a maximum current of 10A (120W max), supporting multiple auxiliary accessories simultaneously.

Integrated 5V USB Charging Port: Features a built-in USB port delivering 5V at 1A to charge smartphones and mount-mounted electronic devices during rides.

High Conversion Efficiency (~93%): Engineered to minimize power loss and reduce heat buildup during continuous voltage conversion.

Comprehensive Circuit Protection: Built-in safeguards protect against over-voltage, over-current, thermal overload, and short-circuiting.

Sleek Black Housing: Features a streamlined, durable black casing designed for optimal heat dissipation and weather-resistant mounting.

Secondary Output (5V USB): Delivers 5V DC at 1A for powering smartphones, GPS navigation systems, and action cameras on the go.

1. Isolate Power Supply:

Turn off the scooter ignition key and switch off the main circuit breaker (if equipped). Disconnect the main battery connector from the vehicle wiring harness.

Verification: Vehicle display, lights, and horn are completely unpowered and unresponsive.

2. Mount the Transverter: 3 min.

Secure the transverter housing to a flat surface on the scooter frame or inside the front cowl using mounting screws or heavy-duty zip ties. Position it where air can flow across the black heat-dissipating casing and the USB port remains accessible.

Verification: The unit is solidly mounted and does not rattle or contact moving steering parts.

3. Connect High-Voltage Input Wires (36V–72V): 5 min.

Connect the transverter's input leads directly to the switched main power supply line coming from the ignition switch:

Red Wire (+): Main battery switched positive line.

Black Wire (-): Main battery negative ground line.

Verification: Terminal wire joints are securely crimped or soldered and sealed with waterproof heat-shrink tubing.

4. Connect 12V Auxiliary Output Wires:

Attach the 12V output wires from the transverter to the vehicle's 12V accessory wiring harness:

Yellow/Red Wire (+): 12V Positive feed to accessories (headlights, horn, display).

Black Wire (-): Common ground negative line.

Verification: Output connections are insulated and dielectric grease is applied to protect against moisture.

5. Test 12V Accessories & USB Port:

Reconnect the main battery pack and switch on the ignition key. Test the headlight switch and horn button, then insert a USB charging cable into the 5V USB port with a mobile device connected.

Verification: 12V accessories operate steadily, and the connected phone indicates active charging.

Wipe the transverter's black housing regularly with a clean, dry cloth to remove dirt, road dust, and mud buildup for optimal heat dissipation. Periodically inspect the high-voltage input and 12V output wiring harness for frayed insulation, exposed leads, or loose terminals. Ensure the rubber seal on the integrated USB port remains firmly closed when not in use to prevent water ingress and corrosion. Avoid directing high-pressure water jets or harsh chemical cleaners directly at the wiring joints or USB opening during vehicle washes. If you notice any unusual heating, flickering accessories, or loose wire connections, turn off the main battery isolation switch immediately and re-verify all electrical terminals.
