    MP-2 model works well for a third of the price of the usual options
  

*by M***M on Reviewed in the United States on July 7, 2020*

I actually own both models (MP-1 & MP-2), but really only recommend the MP-2 for most people, unless you play with little or no OD/distortion.The MP-2 works well for a third of the price of the usual options.  As others have said, it would be nice to have a couple 500mA ports, but you can still buy the Voodoo Lab "Current Doubler Adapter Cable", which is a "Y" adapter that merges two 9V 300mA ports into a single 9V 600mA port.  There's also the "Voltage Doubler Adapter Cable", which merges two 9V 300mA ports into a single 18V 300mA port.Both adapter cables require using two ports of the same voltage, which is why you can only use the 9V ports, since there's only one each of the 12V oand 18V ports.  The drawback is that you have to use-up two ports for one device, but you can always compensate by using a Y-splitter cable or a daisy-chain cable with other ports, so long as none of your pedals on the daisy-chain have noise issues.  If so, then put the noisy pedal(s) on a dedicated/isolated port -- only problematic/noisy pedals really need to be on isolated ports, so daisy-chain the quiet ones (without going over the port's mA limit!), and leave some open isolated ports for the problem children.The Voodoo Lab adapter cables aren't too badly priced, at $7 each, although everything on Amazon was priced higher and demanded shipping charges when I was looking.  But if you search other music sales sites, you can find them for $7 and free shipping.  In any case, this is a relatively inexpensive workaround for the 300mA limitation, and $60 for the power brick plus $7 for the Current Doubler Adapter combined is still a great deal compared to a $200 power brick.There also seems to be a lot of confusion on whether these models have isolated ports.  The MP-1 does NOT have isolated ports, while the MP-2 DOES have isolated ports.  Power-related noise mainly comes from two places: 1) the 50/60Hz hum from AC power, and 2) problematic/noisy pedals from bad power supplies or bad pedal wiring/shielding.  The MP-1 has some AC power hum filtering, but it's not very good.  It is fine when playing clean and tolerable with low gain, but too noisy with high gain.  I wouldn't go as far as some people saying that the MP-1 is just a daisy-chain cable in a box (it still does some power-related protections and amperage management), but noise-wise, it is pretty much the same as a daisy-chain cable.On the other hand, the MP-2 model is noticeably quieter, or at least mine is quiet.  This is replacing my current setup of 100% rechargeable batteries for all pedals, so my baseline is absolutely zero AC power hum.  I think that people with the MP-2 who complain about the power brick's being noisy either have a defective unit, or the noise is not power-related, such as interference (EMI/RFI) from things like fluorescent lights, TVs, radio signals, etc, detected in the guitar pickups or in any pedal's audio circuitry (not power) -- none of which will be solved by isolated ports on any power brick, nor even using batteries.  For example, I own two pedals that faintly pick-up radio stations when gain is high, even when running off batteries.Also, I have not experienced any heat issues with either model.  Keep in mind that the power input is another difference between the two models.  The MP-1's input is 1A, while the MP-2's input is 2A.In any case, to understand the main difference between the two models, think of the MP-1 as strictly an AC power hum filter (albeit a weak one), and think of the MP-2 as an AC power hum filter plus a problematic/noisy pedal isolator. If all your pedals are non-problematic (noise-wise) and you're just playing at home as a hobby with little or no gain/distortion, then you can likely get away with just the MP-1 model.  But if you have any problematic/noisy pedals, or intend to buy more pedals and want to future-proof things, or if you play with high gain/distortion, then you probably want the MP-2 model.  If you play in an actual band, then you definitely want the MP-2 model.

     This review of of the Mefe MP-2 compared to the Mefe MP-1. (See, my Mefe MP-1 Review). I focus on evaluating audio noise characteristics.MP-2 Amazon $49.99 (5 stars) 8 outputs Transformer Power Supply to MS-2: (picture incorrectly shows 18V 1 Amp transformer) The MP-2 input from the transformer is shown as 12V @ 2000mA power input jackMP-1 Amazon $28.99 (2 stars) 10 outputs Transformer Power Supply to MP-1 as indicated 18V @ 1000mA Power input JackConclusions from Testing MP-2The Mefe MP-2 does not have the terrible background hum identified when testing Mefe MP-1. See 2 videos. Video of loud him under Mefe MP-1 testing when 2 of pedals are using it for power. (Mefe Loud Hum from MP-1). Note that the sound goes away by changing the power of one the pedals to a battery.HOWEVER for Mefe MP-2 testing the background hum is NOT an issue. (See video ‘Switching from MP-1 to MP-2’). The significant background hum stops when I, in the audio/video switch from the MP-1 to MP-2 power supply. The MP-2 specification states ‘isolated inputs’.The MP-2 is well priced compared to competing power supplies. Note many are around $200.The cables for to connect the power supply are appropriate lengths and very good quality, There are also 2 cables for switching plug polarity.I included photos of the Mefe MP-2 with the case open as part of the discussion on Donner and other power supplies and the putative existence of isolation and optical isolation circuitry.I received an Amazon gift card from a vendor to purchase these Mefe MP-1 and MP-2 power supplies.*** Details of Testing ***My intent was to reduce or identify audio noise due to audio cables, amplifier power, guitar pickups or pedal electronics. And to text the pedals independently. The ‘independent pedal’ testing approach almost missed the fact that a test case of TWO pedals did not identify a loud hum,System Setup for TestingGuitar amplifier: Yamaha TRH 10C I used the battery power option so that powerline sourced noise is not a factor.Tested pedalsElectro Harmonix 720 Looper: 9V 75mAElectro Harmonix Pitch Fork : 9V 30mADunlop Cry Baby Model GCB95 9V 20mA Note: mA is from current draw as stated in  manufactures spec.Test CasesTest Case 0: Cry Baby and Pitch Fork both use Mefe ** MP-2 ** Power supply Background sound is the same as for 9V battery Note for the OTHER Mefe ** MP-1 ** power supply this test created a loud, unacceptable humCase 1: No device power supplies used.

    Nice Quiet Power Supply
  

*by M***E on Reviewed in the United States on December 17, 2020*

Pros: Price, SizeCons: Layout (personal preference)I purchased this for my first pedal board build.  I wasn't the cheapest option overall but I wanted something with isolated outputs and this was the best deal in that category.  I have another cheap daisy chain style power supply and it does introduce quite a bit of noise. This power supply isn't totally dead quiet but it is a big step up over the cheap one.  I do not have another more expensive name brand PS to compare to but at a fraction of the cost, I'll deal with the tiny bit more noise if there actually is more.  I have only 2 issues with it and neither of them are technically a problem with the PS itself.  I wish it would allow you to switch the voltage on the 12 and 18 volt ports to 9 volts.  I know this isn't a feature and I knew it when I bought it but if I had to do it again, I would probably have opted for another option with that feature or just one with all 9 volt ports.  The second thing is also not something technically wrong with the PS but after setting it up, I think that having all the ports on 1 side would have allowed for a cleaner setup.  Maybe there are some pedal board setups that work better with this style but I would have preferred them all on one side.
