PREOWNED – FULLY TESTED – COMPLETE AND IN GREAT CONDITION
The iFi iPower 5V is a low-noise DC power supply designed to replace standard stock wall adapters and reduce electrical interference in sensitive audio and video gear.
Key Specifications & Features
• Output Voltage/Current: 5V / 2.5A (on the standard iFi iPower2), though higher-tier variants like the iPower X offer 5V/3.0A and the heavy-duty iFi iPower Elite pushes up to 5.0A.
• Noise Floor: Extremely low at roughly ~1 microvolt (1µV).
• Active Noise Cancellation: Uses phase-inverted cancellation circuitry to actively kill incoming electrical noise from AC wall outlets.
• Included Adapters (iPower2): Ships with multiple barrel size tips (3.5×1.35mm, 4.0×1.7mm, 4.8×1.7mm, 5.5×2.1mm, 5.5×2.5mm), a reverse-polarity center-negative tip, and USB-C/USB-micro DC pigtail cables for 5V devices.
Common Uses
• USB-powered DACs, network audio streamers, and headphone amps.
• Single-board computers like a Raspberry Pi.
• Routers, media streaming sticks, and select turntables.
US$50 looks fair to slightly good for a used 5V iFi iPower, and it’s right around the going rate I’d expect for this class of low-noise audio PSU. New 5V units sit notably higher, while recent used comps cluster in roughly the US$50–US$60 range, so this is not a bargain-bin steal but it is a sensible buy if it’s genuinely clean.
The appeal here is straightforward: these supplies are popular for cleaning up streamers, DACs, and small network gear without getting fancy about it. If it’s original-owner, tested, and includes the right barrel tip and cable, that adds real value. At US$50, the main thing is simply confirming it’s the exact 5V version and that the plug size matches your gear; otherwise, it’s a solid little utility piece at a fair price.

iFi Audio is a British hi-fi technology company founded in 2012 by Abbingdon Music Research (AMR), a prestigious manufacturer of high-end electronics based in Southport, England. The venture was conceived as a way to democratize advanced AMR engineering by applying proprietary technologies developed for premium home audio to portable, more affordable devices. This strategic pivot proved remarkably successful, establishing iFi as a bridge between audiophile-grade sound quality and accessible pricing.
The brand specializes in portable and desktop audio components, with a product portfolio exceeding 50 devices spanning DACs, headphone amplifiers, Bluetooth streamers, music players, power conditioners, and cables. Flagship products include the iDSD Micro, Hip DAC, xDSD, and xCAN amplifier, all engineered to deliver high-resolution audio support and studio-quality fidelity in compact form factors. iFi has also gained recognition for innovation in wireless audio, notably with their GO Pods earphones featuring xMEMS technology and their Bluetooth-enabled DAC/amp solutions.
iFi occupies a distinctive mid-to-premium market position, offering audiophile-caliber performance at entry-level to mid-tier pricing. The company sources components globally from Germany, Japan, and the USA, and employs proprietary technologies such as PureWave balanced circuitry to minimize noise and distortion. Rather than competing in the ultra-luxury segment, iFi targets discerning listeners who demand measurable sonic improvement without premium price tags, making it a trusted choice for both portable and desktop audio enthusiasts.
