QNAP SP-1BAY-ADAPTOR 36W External Power Adaptor for 1-Bay NAS
Overview
The SP-1BAY-ADAPTOR is a genuine QNAP replacement or spare power adaptor delivering 36W (12V DC at 3A) to compatible 1-bay NAS enclosures. If an original adaptor is lost, damaged, or you need a spare on-site for a deployment where NAS downtime is unacceptable, this is the factory-spec replacement — not a generic third-party unit that may undervolt the system during heavy disk I/O. The wide-range AC input (100–240V) makes it suitable for both domestic and international installations without a step-down transformer. Look for the QNAP storage and NAS line for compatible enclosures.
Compatibility
Designed for QNAP 1-bay NAS enclosures that ship with a 36W (12V/3A) power adaptor. Verify your unit's OEM power requirement matches 12V DC at 3A before ordering — 1-bay models in the NAS and network storage category that shipped with a 36W adaptor are the correct application. Units requiring a different wattage or voltage (e.g. models needing 19V or higher-amperage supplies) are not compatible. Check the label on your existing adaptor or your enclosure's spec sheet to confirm the 12V/3A rating. If you're building out a multi-unit edge or surveillance NAS deployment and need power planning guidance, review the power supplies and UPS section for complementary infrastructure.
Installation Notes
Input accepts 100–240V AC, so no voltage selection switch is required — plug directly into any standard outlet within that range. Output is 12V DC at 3A; do not substitute with a higher-current adaptor without verifying compatibility with your specific NAS model. Pair with a quality surge protector or UPS to protect the NAS and attached drives from power events — particularly relevant in warehouse or industrial environments where power quality is inconsistent.
