Suptopone 42V 2A Replacement Charger for 36V Scooters & Hoverboards — 3-Prong 8mm, Fireproof ABS, Safety Protections

Suptopone 42V 2A Replacement Charger is a compact, fireproof ABS power adapter that safely recharges 36V lithium scooter and hoverboard batteries via an 8mm 3‑prong connector.

Designed as a direct replacement for many 36V lithium battery systems, this charger delivers a regulated CC‑CV output up to 42V and 2A, with global input compatibility (100–240VAC, 50/60Hz). The molded fire‑resistant enclosure and built‑in protections for short circuit, overcurrent, overvoltage and overpower help reduce charging risk when used properly. A two‑color LED gives clear status: red while charging and green when fully charged or unplugged.

How do I know this charger fits my scooter or hoverboard?

Check the battery voltage, connector type and plug diameter before ordering. This unit is meant for 36V lithium battery packs and uses a mini 3‑prong inline connector about 8mm in diameter. It is not compatible with lead‑acid packs, different voltages, or devices that require a different plug shape.

• Output: 42V max, 2A (CC‑CV charging)
• Connector: 3‑prong inline, approx. 8mm diameter
• Battery type: 36V Li‑ion only — do not use with lead‑acid
• Not suitable when connector polarity or size differs

What safety features and indicators does it have?

The charger uses multiple internal protections to guard against unsafe conditions during normal operation. The case is made from fire‑resistant ABS to improve durability, and the LED provides a simple, immediate view of charging status so you know when your battery is full or disconnected.

• Protections: short circuit, overcurrent, overvoltage and overpower
• LED: green when idle/full, red while charging
• Fireproof ABS housing for improved safety and longevity
• Auto cut‑off once charging completes

How fast will my battery charge and what environments are safe?

With a true 2A output, this charger refills a 36V lithium battery faster than many lower‑rated adapters, though total time depends on battery capacity. Always charge in a dry, ventilated area and do not use the charger if the battery, connector or charger appears damaged or wet.

• True 2A output for relatively quicker charging
• Works on 100–240VAC mains worldwide
• Avoid wet environments and damaged batteries/connectors
• Not intended as an on‑vehicle e‑mobility charger accessory

Who this charger is for: Riders and owners of hoverboards, scooters and personal electric vehicles that use 36V lithium battery packs and an 8mm mini 3‑prong inline connector will find this Suptopone replacement useful. It’s aimed at anyone who needs a reliable, compact replacement charger with safety protections and clear charge indicators — provided you confirm voltage, connector type and polarity before use. Avoid buying if your device uses lead‑acid batteries, non‑matching connectors, or different system voltages.

Important: Do not use this charger if the battery connector or polarity don’t match, or if the battery is damaged. If you receive a defective unit, Suptopone provides an 18‑month warranty and straightforward replacement or refund support without the need to return the broken item; contact customer service for assistance.
