Review: Needed a quit power source for my IFI headphone amplifier. - So far so good. Fast delivery. Using on my Douck Audio U10 headphone amp. Works great,no static or noise. Sometimes you get bad noise off of those little cube phone chargers. Plus manual states it needs at least 2amps to run right. And it does really needs the extra amps. I originally bought to use with my IFI air can headphone amplifier. But decided to try it out on the U10. It works great and it is a great improvement with this little unit. I might just keep the U10 connected now.
Review: Great 5V power brick that can provide up to 4 Amps - This is the second one that I have bought to replace failed power supplies by other manufacturers. The two things that really stand out in its favor is the UL rating and the 4 Amp capability. The first is quite unusual for power bricks. Second, most cheap power bricks (that come as part of a product) fail because they are used at or near their current rating and the 4A rating gives some head room and should make the brick last well past the lifespan of what it is powering.
