🧰 Product Quality & Specifications
The Pigtone 9V DC power supply is designed for simplicity and efficiency. It offers a regulated 9V output at 2A (2000mA), enough to power most standard analog pedals and other 9V DC electronics. The center-negative polarity makes it compatible with the majority of guitar effect pedals on the market today.
Here’s a quick overview of its key features:
- Output Power: 9V DC, 2A max (suitable for 6–8 pedals depending on draw)
- Input Voltage: 100–240V AC, making it globally compatible
- Plug Type: Standard US plug with a 1.2-meter cable length
- Accessories Included:
- 8-way daisy chain cable
- Two polarity-reverse adapter cables (straight and right angle)
- 1x 9V battery snap adapter
In terms of design, the unit is slightly bulky due to the inline transformer, but it’s still compact enough for desktop or home studio setups. The cable feels decently built and flexible, not overly stiff like some cheaper alternatives.
⚡ Performance & Efficiency
One of the standout features of this 9V DC power supply is its high current capacity. Many inexpensive power supplies only provide 1A (1000mA), which limits you to around 4–5 pedals. The Pigtone model doubles that with 2A of current, making it possible to power up to 8 standard pedals or multiple 9V devices without issue.
Noise suppression is another important consideration when dealing with daisy-chained devices. This adapter includes CLC filter circuits and magnetic rings designed to reduce electrical noise and ripple (under 30–50mV). While it’s not a substitute for a fully isolated power supply, it does an admirable job keeping unwanted hum and hiss to a minimum in most setups.
For guitarists using basic analog pedals, the noise level is barely noticeable, and for hobbyists powering Arduino boards or small devices, performance is generally smooth and stable.
🥇 Why It’s Better Than the Competition
Compared to similar low-cost adapters on the market, the Pigtone 9V DC power supply stands out for a few key reasons:
- Higher Current Output – With 2A of power, it handles more devices than many competing units capped at 1A.
- Noise Control – Built-in filters help suppress high-frequency noise and voltage ripple—often a weak point in cheaper power adapters.
- Included Accessories – Comes with multiple connectors, including reverse-polarity cables and a battery clip adapter for older or specialty gear.
- Universal Voltage Input – Ideal for international users or frequent travelers, supporting a full 100–240V AC input range.
- Great Value for Price – It offers features typically found in power supplies costing two to three times more.
