Electric unicycle charging typically runs at 67V-84V depending on pack configuration, proprietary connector. Higher-voltage packs on electric unicycles make using anything other than the specified charger particularly risky — voltage mismatches here have less built-in protection than consumer electronics standards.
Before buying a replacement
Confirm exact voltage and connector polarity before substituting a generic charger for a electric unicycle — unlike phone or laptop charging, this category hasn’t converged on a shared negotiation standard, so mismatches carry more real risk.
