Frequently Asked Questions
Does the NextCore640 work with the KingBull Hunter 2.0S?
Yes. It is offered as the +$259 power upgrade for the KingBull Hunter 2.0S — it tops off the bike battery and runs your gear on long, off-grid rides.
What can a 640Wh power station actually run?
With 600W rated (1200W surge) output across 8 ports, it charges your e-bike battery, phones, cameras, lights, and small electronics, and provides <10ms UPS backup power at home during outages.
Can I use it with other e-bikes or brands?
Yes — it is a standalone portable power station, not bike-specific, so it charges any e-bike or gear through its ports. We offer it as the Hunter 2.0S power upgrade, but Bakcou and other riders can use it too.
