Rechargeable power supply station....?

and 8 eneloop pros.

Just reverse the polarity on the attached cable.

I use a couple of Warwick Rockboard Power LT XLs. Bit of a mouthful but they're basically the same thing as the Mooer. As long as you make sure they're charged when you need them, they're great. Obviously the more pedals you connect the greater the power demands and the faster it will discharge. Hence why I use two on my main board (over 10 pedals) and try to balance the current draw of my pedals between them so they run out at roughly the same time.

Got myself a good wireless system (Smooth Hound) so as long as my power supplies are charged I only need one cable running from my board to the amp.

Edit: Thomann do a Harley Benton equivalent which has a greater overall capacity but can allow slightly less current draw at any one time. Might be worth checking out.

Yep, I'm using a Warwick Rockboard Power LT XL on a board with 5 pedals. It's awesome. The only small gripe I have about this particular model is that there's no on/off switch - the only way to turn it fully off is to disconnect it.

S.P.

Yeah that isn't ideal...I think the Mooer and the Harley Benton have proper on/off buttons.

Also made my own, about £25 and 3 X as much energy storage as the mooer one. Mix of Amazon and eBay parts (only 3 parts). Not sure how many pedals it will power at once though, 5 so far is ok.

With the Pros, my Enveloop solution is 2500mAh. I guess there's nothing stopping you running multiple units across a number of pedals or wiring multiple packs in parallel. Would be interested in knowing what your setup is comprised of...?

Anyway... It's not just about how many pedals that your batteries can power... its about how long your power source can operate them for.

You may find this interesting... [url="http://stinkfoot.se/power-list"]http://stinkfoot.se/power-list[/url]

Basically, you can keep adding pedals, in my case, up to the point of 2500mA (possibly up to 3000mA) ... (beyond that the pedals will be drawing more power than the power supply can physically supply) and it will power them for an hour (based on 2500mA). If you have 1250mA draw, you can power them for 2 hours... 625mA will be 4 hours... and so on. So for most analogue pedals, you can power them for ages... If you start lobbing on Strymons and other digital pedals, you are soon eating into the amount of time you can sustain the draw of power. In reality, if you have a digital laden pedal board, you are likely still going to be able to a couple of sets worth as long as you remember to turn the power on and off between playing.

In short, 2500mAh / pedal draw in mA = playing time.. (but most of you could probably figure that one out)

I had to check but as far as I can tell I can get up top 800 mA draw and the storage capacity is 20000 mAh - so a lot of time available there, but no good if you have big draw pedals. At the moment I've got a spectracomp, tender octaver, B3K, VMTD and a bass synth wah on a daisy chain. It has no issues. My system is a LiOn power bank, a step up converter from 5v to 9v and a polarity reverser.

I was worried that the step up converter might introduce noise, but dead silent, at least with these particular pedals.

So something like

and this

?

Thats one cool looking solution! I like a lot! If I understand correctly, the on above will supply 3.4A... that would cater for most digital boards pretty easily! Obvs, you'd probably need to convert the polarity on the plug... but thats no bother in the grand scheme of things...

The first two are pretty much the system - just used this battery pack instead: https://www.amazon.co.uk/Magigo-20000mAh-Portable-Rechargeable-Flashlight/dp/B0716XZBB2/ref=sr_1_7?ie=UTF8&qid=1503071086&sr=8-7&keywords=magigo

The 800 mA limitation comes from the 5v-9v converter itself, not the battery, I think they just lose performance if you try to draw to much, but don't know anything about that side of it. Also worth noting that the step up in voltage will drop the mA available by roughly half (at a guess), so you have a limit there too. Instead of one big pack you could use multiple small cheap ones if need be.

I use a very similar setup to power a Polytune, VT Bass Deluxe and a TC Spectracomp. Lasts for ages, and I've had no noise issues at all. The only problem I have had is that the power pack switches itself off if it doesn't have a minimum of about 30 or 40mA being drawn, so I've added an LED and resistor to maintain that constant draw.

Does anyone make a battery power supply with isolated outputs?
[/quote]

I don't know but it would be fairly cheap to build a LiOn pack as above but use a dedicated supply to the pedal that needs the isolated supply.

Edit: Are you sure you need a isolated supply at all, As I understand it noise could be coming from the power supply itself, so using a battery pack could eliminate the source. I just do this by trial and error though, so other than just give it a go, I don't have a techie type answer!

Smooth hound doesn't seem to like using a battery pack with another pedal, generates a load of noise....
[/quote]

Just have a dedicated pack for the smooth hound, it'll still be cheaper and last longer than the mooer type off the shelf units.

I use a GigRig Timelord to isolate my Smooth Hound from the other pedals sharing the battery pack. Works like a charm. Had to put a little polarity reversing adapter on it though, as the Smooth Hound requires a centre-positive connection.

Just thought I add a word of warning on my particular rig. I keep getting a random protection function happening on the battery pack, where all 4 leds flash but no current can be drawn. Seems to be okay sometimes and not others! I think its an issue with this particular battery, so avoid the one I linked to! Just charging it to full now in case its a charge issue.

The only downside of these high capacity batteries I can see is the long recharge times and obviously the limited draw from them with the USB converter on them. I'm actually interested in it as a portable way of charging my iPad...

Anyway... at least with my eneloops I can charge them relatively quickly... but that doesn't mean I'm not interested in having some new shiny to play with :P

The decision to not have centre negative on the Smooth Hound was always an odd decision to me. Anyway, re:Timelord... was looking into these... the Diago Isolator would have been a cheaper option... but it's still not a cheap option.

Just to update myself, something very weird going on with mine. USB in and all pedals power up, take out the USB and plug back in and the protection circuit is triggered. Put the battery on charge and it resets the protection, plug the USB back in and it works again.

What is going on here?

Sounds like it could be some surge/short happens when you plug it in initially. I'm guessing the protection circuit is fairly sensitive.... and maybe the step up circuit is a bit harsh on sensor. Hmm. Dunno.
