This 53.6V 2A charger provides safe, stable charging for Segway and Ninebot MAX scooters, including G3, ZT3 PRO, GT3, F3, and F3 PRO models. Designed for lithium battery packs, it restores full power efficiently while maintaining battery health through precise voltage regulation. Technical Performance The charger converts AC 100?240V input to a steady DC 53.6V 2A output, ideal for 48?54V-class lithium systems. Built-in overvoltage, overcurrent, and short-circuit protection automatically adjusts current flow during charging to prevent overheating or cell damage. The fireproof ABS enclosure enhances safety and durability while keeping total unit weight low for portability. Practical Applications Daily commuting: recharge Segway scooters overnight for next-day use. Fleet use: reliable charging for multiple scooters in shared or delivery settings. Travel and replacement: compact enough for backup or mobile use. Measured Advantages Compatible with multiple Segway by Ninebot models. 2A output balances fast charge times with optimal battery longevity. Smart protection circuitry prevents thermal and voltage stress. Universal 100?240V input for global use. Fire-resistant ABS case for enhanced safety. Design Trade-Off Single-port configuration limits simultaneous charging?optimized for focused, controlled output rather than multi-device flexibility.
