|This is the first isolated power supply design to fit under a Pedaltrain Mini (or nano or metro).
|True Tone One Spot
|I had one of these, but I found it passed noise back when my computer was on the same power supply.
|I currently daisy chain with one of these. The cable is starting to wear already though, so I may go back to a One Spot. They also have the Diago Powerstation which can output 3000mA! This might even fit under a pedaltrain mini, will try and let you know:
|If you’re daisy chaining and need just one or two pedals isolated, this can be a cheap addition.
|Similar to the Diago, I haven’t tried one yet, so I don’t know how good it is.
|Mooer Micro Power
|93.5×42×36 (mm) These outputs are independently filtered outputs, but not transformer isolated I believe. Here’a a pic on a Pedaltrain Nano: https://osiamo.files.wordpress.com/2014/07/bruceb_mooerboard.jpg
|95×38×29 (mm) Overall slightly smaller than the mooer, and according to the manufacturer isolated outputs. Super cheap at US$35.
|Mosky Nano Power Station
|93×38×31 (mm) Pretty much the same size as the DC-Tank, but doesn’t say the outputs are isolated.
|One Control Micro Distro
|98x48x35 (mm) Another non-isolated solution. I’ve seen people fit these into Pedaltrain boards here and here. It’s not isolated though: http://www.thegearpage.net/board/index.php?threads/new-mini-power-supply-for-pedaltrain-mini.1177229/
|Battery powered solution that fits under newer Pedaltrain Minis and original ones if you’re willing to cut away part of the bottom.
|T-Rex Fueltank Junior
|Pretty much the largest that’s worth considering. Takes up quite a lot of space on top, but you can fit it underneath if you cut away and added higher feet: http://www.tdpri.com/forum/stomp-box/296043-pedaltrain-mini-has-no-room-power-supply.html
|Rockboard Power Lt XL
|A similar idea to the Pedaltain Volto, but cheaper, adds a 5V USB output in addition to 2 standard 9V outputs, and at only 5.8cm wide is small enough to fit under the older Pedaltrain Minis (made before summer 2012) which cannot fit the Volto or Cioks DC-5
|Mouse Electronics 6×9
|Another small isolated power supply, not quite small enough to fit under a mini or nano without riser feet
