Had a bad experience with the Onstage unit, which claimed to be isolated, but with my simple 9 volt pedals was a mess of noise and one pedal didn't work at all. So, got nervous about trying another lower cost unit. But again, all I'm running are simple 9 volt <100 ma pedals. Did my research and decided to give this one a go, knowing I had free return. I was amazed to find it was whisper quiet, powering my 6 pedals with no issues at all. Also this unit is very small, so will easily fit underneath all but the lowest pedalboards. My only possible concerns are how rugged the unit itself and its power supply will prove to be. Only time will tell, but so far so good. Of course replacing the power supply would be an easy low cost fix if ever needed. If I did so I'd look for a power supply with a longer, heavier cord. Review: Isolated power supply for not a lot of money - This is my second power supply that I bought for my guitar board; the first one was for a bass board. Both supplies worked great for all my pedals and they have a small form factor that helps with mounting them under the boards. These supplies helped with the unwanted noise and tidier installation while providing plenty of power for my needs. Hopefully, they will last, fingers crossed. ## Features - Totally Isolated Design : Caline Cp-205 Fully Isolated Pedal Power Supply, Not Only The Outputs Are Independently Functioning, But Also All Ground Wires Are Isolated, Therefore, It Is A True Fully Isolated Pedalboard Power Supply With Noise Reduction Function - 8 Isolated Outputs : Caline Cp-205 Fully Isolated Pedal Board Power Supply Has 8 Dc Outputs,Including 7 X 9v 300ma And 1 X 9v 500ma, Suitable For Both Analog And Digital Guitar Effect Pedals - Extremely Portable : Made Of High Quality Aluminum Alloy Material, Lightweight And Portable, Surprisingly, This Fully Isolated Power Supply Pedal Board Only Weights 220g And 2.5cm In Thickness - Short Circuit Protection : Each Outputs Of This Pedal Power Has Independent Short-Circuit Protection And Independent Indicators.

Both supplies worked great for all my pedals and they have a small form factor that helps with mounting them under the boards. These supplies helped with the unwanted noise and tidier installation while providing plenty of power for my needs. Hopefully, they will last, fingers crossed. ### ⭐⭐⭐⭐⭐ This is a great power supply! *by L***L on March 2, 2025* This power supply is completely isolated on both the ground (sleeve connector) and the -9-volt (center pin connector). This puts it in the same category as Voodoo Labs, Cioks, and Strymon products. While I have doubts about its build quality compared to those brands, it is priced at one-quarter of their cost. Previously, I purchased the "STRICH Totally True Isolated" power supply, and while the -9-volt connection was isolated, the ground was common across all the connectors. This setup resulted in a terrible high-pitched whine from my Tonex One. Now my pedal-board is totally silent.
