SO my question is about powering the HX Stomp with a PD Battery Bank via Ripcords 5V to 9V adapter. https://myvolts.com/product/39019/Ripcord_9V_c-ve So i also got a 2.1MM to 2.5MM adapter but hesitant if this should work? (A few people on youtube are using this with a PD Battery Bank) byt my math it's 1300mA which from what i understand is acceptable.
PD Powerbank Batteries output to ripcord is12 Watts at 9 VOLTS
1.3 Watts per volt= 1330mA
