Want a wireless pedalboard? $80 18ah Powerbank powers 5-19v DC directly.
Here's a small Powerbank I've found that has a unique circuit in it that'll power 5-19v DC items directly. If your desired product has an AC brick that converts to DC, this will power it (well, almost every item I've seen for MI). Even the TC Helicon 150fx speaker, who knows for how long though. If it really delivers its ah rating, it should last 4-6 hours. I'd bet it runs for 1-1.5 though.

No MartyC,
I just found this yesterday. This isn't the step up transformer+Powerbank that was written about here a couple of months ago (that was only good for 9v products), this one has much higher voltage available and can do the same direct DC power trick but for larger products, like the Voice live 150fx, QSC Touchmix, Play Acoustic, Roland battery amplifiers, etc., all sans AC inversion (and its resulting battery power efficiency losses). It seems to be a unique product and is an exciting thing to see. I'm glad to have found it.

It'll probably power the play acoustic alone for a good long time, so long as the screen isn't perpetually lit. The 150fx, not so long,I'm afraid. If the power rating holds true from the larger banks, they're measuring the 18000mah at 3.2v, meaning that it's really only 4500mah at 12v and only 3600 of that is usable.
My educated guess is 1.2-2hours. Possibly/doubtfully 3 hours, mostly if gains in efficiency translate to good runtime. At this price though, you could buy two or three to make it a through a couple of sets.

Just back from looking up power supply info on the Helicon VoiceSolo 150FX and realised my memory had failed me. The 150FX needs 42.5 [email protected] to run, so cannot be run by this Suaoki G7 as I'd thought.
I didn't remember this box running at so high a voltage but it is what TC Helicon says so the correction runs.
