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.
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.

Eliminates electrical interference.
This combined with the defender+ completely fixed the electrical interference nightmare I was having in my recording studio. Wish I had been advised about it sooner.

A VERY CAPABLE PS
I am struck by the incredible performance of this 15VDC power supply. I am using it with my Schiit Mani phono preamp, which is hugely sensitive to EMI/RFI and 60HZ loops. But the iFi handles it very well. If you are looking for a quicl fix to a bad noise situation, this little guy gets it done.

ifi power adapter number 3
This is a very good replacement to any cheap bog standard adapter in its range and this is just one of many they do. The adapter is no bigger than the one it replaces and is far more pleasing as its so quiet, this one I bought to power my ethernet switch and it is a big improvement on the one supplied with it, very pleased and would recommend these as a good step up in reliability and efficiency.

Good value and it works
I’ve used it as an upgrade to the wall wart that came with my WiFi router/modem. I have a Roon based music system and anything you can do to reduce the noise floor is worth doing. If you don’t want to go to the whole hog and buy a large linear power supply this is a worthwhile upgrade that makes a difference. Recommended.

Great little power plug
Purchased this because of the reviews it’s a stop gap until I can afford a proper Linea power supply

Ifi Power
A good match for the Ifi DAC/preamp …worth the money for an external power supply

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.
