AC adapter for a wide range of small electronics, delivering selectable DC9V outputs and interchangeable tips, the SZZKtech DC9V AC Adapter reduces charger clutter and keeps kit running. Dependable power lets hobbyists and home users get on with projects without constant interruptions. Will it handle heavier loads and protect sensitive kit over time?
⚡ At a Glance
- • Power Output: Selectable DC9V outputs compatible with 2A, 1.5A, 1A, 800mA, 500mA, 200mA and 100mA
- • Best for: Home and hobby electronics such as routers, guitar pedals, label makers and security cameras
- • Not ideal for: High-power appliances or devices that require voltages other than 9V or more than 2A
Input accepts AC100V–240V at 50/60Hz and maximum output is 18W. DC plug is 5.5mm x 2.1mm with eight extra tips included, polarity is inner positive by default and changeable with the supplied reverse cable.
Wide compatibility - with eight interchangeable plug tips and a polarity-reverse cable
A 5.5mm x 2.1mm main plug ships with eight extra plug tips to match common DC sockets, and an included polarity-reverse cable swaps inner/outer polarity as required. The unit accepts AC input from 100V to 240V at 50/60Hz, letting it work internationally.
Quickly match a variety of devices without buying separate chargers, saving time and space. Fewer compatibility headaches when swapping between routers, label makers, pedals and development boards.
Built-in device protection - thanks to over-voltage, over-current, short-circuit and surge protection
Protection circuitry covers over-voltage, over-current, short-circuit, overload and surge events, and the hardware uses a fireproof shell plus a heat-dissipation board in a fanless design. CE, FCC and DoE VI certifications indicate compliance with recognised safety and efficiency standards.
Sensitive kit receives guarded power delivery, reducing the risk of electrical faults. Certified protections bring greater peace of mind for home and studio setups.
Stable power for demanding accessories - with up to 2A output and 18W maximum power
Output supports multiple current levels up to 2A at 9V, with a stated maximum power of 18W. Units are tested before shipment to ensure consistent output and low noise in normal operation.
Higher-draw accessories such as tablets or guitar pedals can be powered reliably, while smaller items run comfortably on lower current settings. Avoid running near the maximum continuously, aim for under 80% continuous load for best longevity.

❓ Frequently Asked Questions
Q: Will it fit my device's DC socket?
A: Check the DC socket size and power consumption before use; the main plug is 5.5mm x 2.1mm and eight extra tips are included to match common sockets.
Q: Can it power a device that needs up to 2A?
A: Output supports up to 2A at 9V with a maximum power of 18W, and user feedback reports stable 2A performance for demanding accessories; avoid long continuous use above about 80% of total output.
Q: Is the polarity adjustable?
A: Yes, the default polarity is inner positive and outer negative, and the supplied polarity-reverse cable allows switching to the opposite polarity when required.
