WAWEIS 54.6V 2A AC Adapter for RAD Power Bikes RadRunner

SKU CH-WG03-HR7MQ

A 54.6V 2A charger with 10 ft cord and FCC, CE, RoHS certification for RadRunner e-bikes

  • World-wide 100-240V input charges anywhere
  • 10 ft cord reaches distant outlets easily
  • Over-current, over-voltage and short-circuit protection safeguards the battery
  • FCC, CE and RoHS certified for safety compliance
  • Smart chip prevents overheating during charging

Compatible Charger for RadRunner Bikes

This 54.6V 2A AC adapter replaces the original charger for RAD Power Bikes RadRunner, RadRunner Plus and RadRunner 1 models. It delivers the correct voltage for the 48V lithium-ion battery system used on these e-bikes. The unit is supplied new and built to match OEM specifications.

Check Connector and Battery Voltage

Verify that your bike uses a 48V lithium-ion pack and that the charging port matches the adapter’s output plug before ordering. The charger accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz, so it works on standard mains supplies. A 10 ft power cord is included for flexible outlet placement.

Replaces Lost or Damaged Original Charger

Use this adapter when the factory charger is missing, faulty or you want a spare for travel. Built-in protection covers over-current, over-voltage, short-circuit and total-power faults, while a smart chip adds over-temperature and over-charge safeguards. FCC, CE and RoHS certifications confirm compliance with safety standards.

Questions about this item

Does the 10 ft power cord include both the wall plug and the bike connector?

The adapter ships with a single 10 ft cord that runs from the 100-240VAC 50/60Hz wall plug to the DC output connector for the RadRunner battery.

Is the 54.6V 2A output the only version that fits the RadRunner 48V lithium-ion pack?

Yes — the RadRunner series uses a 48V lithium-ion battery that charges at 54.6V 2A, so this single voltage and current rating is the correct match.

What does the 54.6V 2A rating deliver to the RadRunner battery in everyday use?

It provides the standard 2 A charge current at the 54.6 V termination voltage required by the 48 V lithium-ion pack, with over-current, over-voltage, short-circuit and over-temperature protection active during the cycle.
