Insignia™ - 22.5W Universal AC Adapter for Devices with Round-Pin Connections (5 ft) - Black - Open Box - Excellent

Hello, thank you for your question. This Insignia 22.5W Universal AC Adapter is designed for low-power devices that use compatible round-pin connections. Compatibility with a Hiboy S2 electric scooter cannot be guaranteed, as electric scooters typically require specific charging voltages, amperage ratings, and connector types that may exceed this adapter's capabilities. We recommend comparing the scooter's charging requirements with the adapter's specifications before use. Sudeep | Insignia

Hi, thank you for reaching out. The NS-UNI22WAC supports devices requiring up to 2A at 3V-7.5V, 1.67A at 9V, or 1.25A at 12V. If your electric scooter's charging requirements match one of these voltage and amperage outputs and the connector fits, it may work, We recommend checking your scooter’s power label or user manual to confirm compatibility before use.
