So doing some digging on portable power (really want to use it to process field recordings in real time):
Mixed reviews on the old version of this one, especially when introducing a digital pedal (the website states it was not designed for them). Though that’s from people using multiple pedals (ie tone chasers).
Also found a lot of feedback on the noise, again especially when introducing digital.
I wonder if one of these simple Ripcords on my powerbank will do the trick.
