Generic 42V 2A Charger for 36V (10S) Lithium Batteries — 5‑Tip Universal Replacement with LED

A compact 42V 2A replacement charger with five interchangeable plug options, designed to fast-charge and maintain 36V (10S) lithium battery packs used in scooters and e‑bikes.

This universal charger provides a single, low‑profile unit that replaces lost or damaged OEM adapters for many popular micro‑mobility brands. It accepts 100–240V input for worldwide use, delivers a steady 42V at 2A output suited to 36V lithium (10S) packs, and includes LED indicators to show charge state. The modular plug set covers common DC barrel sizes and airline/XLR‑style connectors so you can match the battery port without soldering or adapters.

Will this charger work with my 36V lithium scooter battery?

If your scooter uses a 36V lithium pack (commonly labeled 10S), this charger is engineered to be compatible. Verify both the battery voltage and connector shape before purchasing to avoid mismatches. It is not suitable for lead‑acid, 24V, 25V, 29V, or 48V systems.

• Output: 42V DC at 2A — made for 36V (10S) lithium packs.
• Check battery label or manual for voltage to confirm 36V compatibility.
• Not for use with lead‑acid or non‑36V battery systems.
• Includes five common connector types to fit many manufacturers.

How do I choose the correct plug and connect it safely?

Select the plug that matches your battery’s input port by comparing dimensions and pin layout. The charger ships with interchangeable tips including two barrel sizes and several airline/XLR variants; the light turns red while charging and green when the pack is full. Always connect the plug to the battery first, then plug the power cord into the wall, and avoid charging unattended for prolonged periods.

• Compare connector diameters and pin counts to your battery inlet.
• Attach the matched tip securely before powering the charger.
• Red LED indicates charging; green LED indicates fully charged.
• Follow manufacturer safety guidance for charging location and supervision.

Which brands and models are typically compatible with this universal charger?

The adapter is broadly compatible with many micro‑mobility and e‑bike brands that use 36V lithium packs and common connector types. Examples include Razor, Jetson, Gotrax, Segway‑style devices and similar models, though compatibility varies by model year and connector variation. Always confirm the connector and voltage for a match.

• Works with many scooters and e‑bikes that specify a 36V lithium battery.
• Commonly used as a replacement for Razor, Jetson, Gotrax, Segway, and similar brands.
• Not all models within a brand share the same connector—verify first.
• Global 100–240V input supports international use with appropriate plug adapter.

What safety features and charging behavior should I expect?

The charger provides a steady current with simple visual state indication and automatic maintenance once the pack reaches full charge. It is intended as a direct replacement charger rather than a serviceable repair part; avoid using it with damaged batteries or incompatible chemistries. Routine inspections of wiring and connectors reduce the risk of poor connections or overheating.

• LED status: red while charging, green when charge is complete.
• Automatic maintenance mode helps prevent overcharging after full state is reached.
• Built for lithium chemistry only—do not use with lead‑acid batteries.
• Inspect plugs and cable for wear before each use.

Who is this for? Riders, fleet operators, and DIYers who need a compact, travel‑friendly replacement charger for 36V lithium (10S) scooter and e‑bike batteries will appreciate this unit. It’s ideal if you want one charger that can serve multiple devices via swappable tips, if you travel internationally and require 100–240V support, or if you need a straightforward, indicator‑equipped charger to keep a spare power source on hand. Confirm your battery voltage and connector type before ordering to ensure safe, reliable charging.
