Most e-bike batteries range from 400Wh to 750Wh. To charge them fully, you don't just need a battery — you need a power station that can handle the specific draw of your charger without wasting half the energy as heat.
The 30% rule: Charging a 500Wh e-bike? You need a 650Wh minimum station — and 800Wh to be comfortable.
1. The "Basecamp" King: EcoFlow Delta 2
EcoFlow Delta 2
1,024Wh • 1,800W AC • X-Stream Fast Charging
If you're hauling bikes to a trailhead, the Delta 2's 1,024Wh capacity and 1,800W output handles even demanding 48V/52V chargers. The X-Stream tech goes from flat to full in 80 minutes — faster than any competitor at this capacity.
✓ Pros
