The optimized 2 A charging current gently and efficiently recharges 36 V Li‑ion batteries with output up to 84 W, with stable regulation and protections.
Standard DC connector 5.5 mm (outer) × 2.1 mm (inner), pin length 10 mm – easy and secure connection to many e‑bike batteries.
The lightweight power adapter is easy to carry, and its LED indicator switches to green when fully charged for immediate status at a glance.
This portable e‑bike charger is designed for 36 V Li‑ion batteries and provides a stable 42 V / 2 A output (max power about 84 W). Thanks to its compact size, it fits easily in a backpack and can be used at home, at work, or on the go from a standard 230 V outlet. The built‑in LED indicator clearly shows the charging progress — it turns green once fully charged.
Electronic protection safeguards the battery during charging and helps extend its lifespan. Typical charging time for a 36 V battery is approximately 4–6 hours, depending on capacity and current state of charge.
Tips for longer battery life: keep charge between 30–60%, avoid extreme temperatures, prefer partial charging (about 80–90%), and avoid leaving the battery connected unnecessarily overnight.
