✅ POWER UPGRADE - Actively detects and removes unwanted electrical noise introduced by noisy stock wall warts or plugs to provide a steadier and more reliable direct current to your device, including turntables, media streamers, phono stages, routers, DACs, audio interfaces, and even LED lighting for studio photos ✅ QUIET COMFORT - Enjoy clear audio and more defined digital video with the iPower's Active Noise Cancellation, technology derived from military applications that acts similarly to noise cancelling headphones by measuring and inverting the signal from your power supply to create a super quiet noise floor and to filter out spurious frequencies introduced by common household equipment that would interfere or muddy your entertainment experience ✅ MULTIPLE APPLICATIONS - Designed to fit common devices, we include 4 different size DC barrel adapters, a center negative adapter for inverting the polarity, and a right angle adapter for when you need more flexibility (The 5 volt version comes with a DC to micro USB adapter, a DC to USB C adapter, and a DC to USB A (female) adapter for use with USB powered gear like the Raspberry Pi or Amazon Fire TV Stick). Choose the iPower that is right for your device based on your devices specifications ✅ IMPROVED OUTPUT/INPUT NOISE SUPPRESSION - The new iPower boasts improved components and thicker gauge wiring to deliver improved output/input noise suppression. It's more than 10 times quieter than most audiophile power supplies and will feed your system’s circuits with ultra-quiet, clean power at both the input and the output stages. ✅ VARIETY OF VOLTAGES AVAILABLE - iFi offers the iPower in 5V, 9V, 12V, and 15V versions to provide power options for many of the most common audiophile equipment, such as a DAC, music streamer or router, or even a guitar pedal. Choose the voltage model that is right for your device based on your manufacturer's specifications The iPower is an advanced DC power supply that instantly improves the audio or video performance of virtually any DC powered product. It is a quick and noticeable upgrade for your entertainment system, whether you're a music lover, musician, audiophile, recording engineer, photographer, or traveler. Even products that benefit from a steady and clean power source, such as an LED studio light, will have less flicker and become more reliable, so you can spend less time trying to setup the perfect shot. We've also included a reverse polarity adapter for center pin negative products, like guitar pedals, so your amplifier only receives the affects you want and not a tainted signal from dirty power. You can expect to hear audio with more detail and clarity, and video will be clearer and crisper because the iPower has an astonishingly low audio band noise floor of just 1uV, removing noise you might not have even noticed was there. It is 20 times quieter than conventional switch mode and linear power supplies, and has been proven to be 100x quieter than standard stock wall warts. The iPower is light, convenient and above all, easy to travel with. Each comes with 5 different barrel tips (as well as micro USB, USB C, and USB A female tips with the 5v iPower version), to ensure use with a wide variety of devices, available in 5V 2.5A, 9V 2.0A, 12V 1.8A and 15V 1.2A versions. Just match the correct voltage, polarity setup, and current output to your manufacturer's specifications and then enjoy!
