Product Overview
Brand: YiKaiEn
Features:
- Exclusive Center-Positive Compatibility: This 9V 1A power adapter only works with center-positive 5.5x2.1mm devices. It is NOT compatible with negative-tip electronics like guitar pedals or label makers.
- Global Voltage Support (100-240V 50/60Hz): Universal AC input works worldwide with stable 9VDC/1A output (±3% fluctuation), ideal for sensitive electronics prototyping.
- Reverse Polarity Protection: Built-in safety circuitry prevents damage if accidentally connected to negative-tip devices.
- Durable Industrial Design: Flame-retardant casing with reinforced strain relief for long-term reliability in lab/workshop environments.
- Precision Power Delivery: Maintains stable voltage (±0.25V under load) for analog sensors, microcontroller testing, and circuit development.
