LEKATO Guitar Pedal Power Supply, True Isolated Pedal Power Supply with 10 Ports, USB Port, Short Circuit Protection, Guitar Pedal Power DC Output 9V 12V 18V for Effect Pedal

Inexpensive and does the job. Some may ague that the more expensive units are "quieter", and maybe for high level recording it might ne so, though not that my ears can detect. But this thing will powertwice as many pedals as power supplies that cost three or more times as much, and I have never had a power supply from this brand fail.Well worth the price!

Great power supply. Plenty of power. No unwanted noise. Great price. I would definitely buy again.

Works perfectly. Was having a noise issue with a daisey chain power supply. This power supply is dead silent aside from the hum from the distortion pedal, which you need a noise gate to get rid of. Reasonably priced, would recommend.

Works great for my pedalboard, doesn't lose power when all my pedals are turned on

I use this unit to power 12 pedals, 14 if you count my killswitch and A/B. It has 10 slots, so I used a daisy chain on one of the spots to power the lower power pedals (compressor, tuner, AB, killswitch). I even use the USB port to power my Line 6 wireless receiver. I have this pretty much maxed out on power usage, and still not a single bit of hum even with my distortions on. You do still get the typical hiss from distortion pedals, but there's no stopping that aside from a noise gate. And the general look and feel of it seems just as good as a more expensive unit like an MXR or VooDoo. My only complaint is that the power supply which powers the unit seems a little cheap, but that's easy to replace of you ever needed to. I haven't had a ton of time to test this out extensively, but it works great now and I plan to just keep it under my pedalbaord and not touch it, so I think it's a win. Great deal for a great product.Update: after using for a few months I have run into a few minor issues. I noticed a quiet high pitched noise (but loud enough for me to notice in a live setting) coming from my delay pedal sometimes. Upon further investigation, I found that this particular channel did not seem to like my higher power use digital pedals, so I swapped a few things around onto a pedal that did not get noisy with that output. Also, when running a multimeter to check voltage, I noticed a few inconsistencies on the voltage supply. One of the outputs runs a tad under 9V, and another was running around 9.3V. Not a HUGE deal as it's still within a 5% tolerance, but weird that it's not the same across all 10 outputs. The one with the low-ish voltage I just use to power pedals with really low consumption, and the one with high voltage I use to run my daisy chain. After those little adjustments all seems well. I'd still recommend this, but I'd do a close check for any noise and do some adjustments or perhaps return for another unit of it's bad enough. Still seems like a reliable unit for a good price.

TLDR: the board is true isolation and supplies the mA it says it doesI was a little worried when I saw some reviews saying the adjustable port didn't work. But I decided, what the heck, it's 50 bucks. After hooking everything up at home, it sounded fine, but I waited until after playing a few gigs to write a review.As you can see, I use several vocal processors, each of which needs 300 mA. The vocal looper not only needs 400 mA, but is also 12v. The built-in power supply on my board was fine when I just had a couple of pedals, but my mic started clipping and I got ground hum as I added more pedals.This power supply brings a ton of juice for the size and price. It feels solid and well-built. It also comes with a 9V battery adaptor, a ton of power patches, and a female-to-female adaptor. Only (minor) gripe is the power adaptor is a little flimsy, but for the price you really can't complain.Highly recommend for busy or power-hungry pedal boards on a budget!

I blow harp, so I don't have a huge collection of pedals, like some guitar players I know, but the ones I have require various different voltages. The MPP-10 was the perfect solution... it powers up to 10 pedals; 7 of the outputs are 9v at up to 300mA, which is sufficient for most pedals. Output #8 is also 9V, but up to 500 mA, for those power-hungry devices. The last two outputs (#'s 9 & 10) are independently switchable between 9, 12, or 18V, at up to 500 mA. This is enough for most any pedal, including those that utilize a vacuum tube (like my Lone Wolf Blues Co. Harp Attack, or Behringer MCC-100 mic preamp (not shown in the pic), both of which use a 12AX7). The photo also shows my two sets of wireless transceivers , which are NOT powered/charged by the MPP-10; they just happened to be on the board when I took the pic, so it looks a bit more cluttered than it is in actual use. Highly recommended!So, this power supply (it's more like a distribution system) will probably meet the needs of anyone who wants to power up to 10 pedals within the MPP-10's voltage & current specs. Big win!

At this price point and the fact that you can make all of the outputs 9v mates this the best power supply under $100 in my opinion.
