my short answer is no, but if you're determined to power it by USB power bank, is there a reason you're not powering the bmpcc via USB-PD? something like https://www.amazon.com/gp/product/B08MQ5XT64 would let you stick to a USB power bank without quite so much ... zapping? i haven't heard of that. but i would be extremely cautious about something making any kind of sound. even more so a "zapping" sound.
