Key features
- Regulated 9V DC output at 1A
- Overcurrent protection with auto-recovery
- Short circuit protection
- Standard 5.5mm x 2.1mm DC barrel plug
- Wide AC input 100-240V (worldwide compatible)
- Efficient switching design with low standby power
- Compact wall-plug design
Good to know
- Verify polarity: center pin is positive on standard barrel
- Do not exceed rated current – will overheat and potentially fail
- Check connector size matches your device (5.5×2.1mm is standard)
- Switching adapters may generate EMI – keep away from sensitive RF circuits
- Not for outdoor use unless in weatherproof enclosure
