It works with virtually any DC powered device and comes in 5, 9, 12 and 15 volts.
Just check the correct voltage and away you go. Clean, audiophile grade power.
iPower
When is a plug no ordinary plug? When it’s an iFi iPower.
Use an iPower to replace your regular power supply for clean, noise pollution free power.
Power hungry
Got underlying noise in your system you can’t explain?
It could be as simple as your power supply.
Upgrade to the iFi iPower to feed your system’s circuits with clean, audiophile grade power and address issues at both the output and input stages.
iPower for LED lights
Photography? No way. iPower can also solve my flickering LED light problem?
Yes, a constant current and voltage power supply like iPowerX will ensure that the current supplied to your LED system will remain stable, no matter the fluctuations of the AC power in your wall socket.
It can be used all over the world as it comes with pins for the USA, United Kingdom, Europe and Australasia.
Quiet! Active Noise Cancellation+® (ANC+) at work!
Exceptionally quiet power. The measured noise floor is 100x quieter than the common noise filter.

Reviews
It works!
I bought this because a review of a DAC for a Raspberry Pi said that the audio performance was poor if there was a noisy switching power supply (PS). This devise provides a much cheaper solution compared to a linear PS and it worked very well. I therefore bought a second.

$49 iFi Low Noise DC Power Supply matches $110 Linear Power Supply in audio quality output!
After doing several rips. I substituted a $49.00 12 volt/1.8amp iFi Low Noise Power Supply for a $110.00 12 volt/ 3amp linear power supply from China and found that the music quality output was just as good at 40% of the cost. Strongly recommend iFi’s range of easy, quick-delivery solutions to dirty AC power for appropriate components like a CD ripper

Try one, one of the best additions to my system!
I need to be careful writing this review as I have read many where the author has raved about a piece of hifi only to find it mediocre at best or to find something far better a month later. So I dont really know how to make this ‘just another 5 star review’ of many other top ranking hifi components. Yes mains treatments are subjective but this little wall wart proved very special indeed!
I was half expecting the ipower to improve things marginally, half expecting no improvement at all, especially as i have a system which puts a big emphasis on mains treatment already. My system is: home built pc, Arcam irdac ii, Rupert Neve RNHP headphone amp, Isol8 Substation 2 mains filter, mains cables from Van Den Hul and Atlas.

Worth the money
Quality product. Noticeable improvement in audio definition.

Worlds quietest wall wart
I got this for a Rasperry Pi I am using as a music streamer. In this application I wanted to avoid switching noise and the only alternative would be a bulkier and more expensive linear supply. If you need quiet power iFi has the right stuff. Now to get the 15v model for my phono pre amp.

Works perfectly with Focusrite Scarlett 6i6 audio interface
Purchased the iFi 12v power supply for use with a Focusrite Scarlett 6i6 audio interface. Works perfectly with a very noticeable improvement in soundstage depth and separation. Wasn’t expecting to hear such an improvement so this is a welcome surprise and is the best fifty bucks I’ve spent in a long time.

EMI (Electromagnetic Interference)
EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.
RFI (Radio-frequency interference)
Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritating, unwanted noise often talked about as an ‘audio gremlin’.
Top tip: just don’t add water.
Switch Mode Power Supplies (SMPS)
A switched-mode power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. It transfers power from a DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics.
Switch-mode power supplies are widely used because of the advantages they offer in terms of size, weight, cost, efficiency and overall performance. They are in themselves noisy and were not designed with audio in mind.
Active Noise Cancellation
Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.
Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.
