It's a spare charger! Just like the charger that came with your Second-Generation Alpha II, Centauri SE or Centauri II bike, this one is UL-listed and designed to provide safe and reliable charging.
Charging will take 5-7 hours (to 100% from 0-5%, depending on battery) and the charger will automatically shut down once the battery is fully charged.
Vvolt is not responsible for any damage from using this charger with a non-Vvolt product. We do not know, and we cannot tell you which, if any, ebikes or scooters are compatible with the VVOLT charger.
*Update- September '25: this charger IS NOT COMPATIBLE with Huffy-brand ebikes, and is likely NOT COMPATIBLE with many other brands.
