Hey Everyone,
So I spoke with an audio friend of mine, an older guy who’s a PhD in electrical engineering. He basically said that the 16V DC from the Krisdonia should be ok. He also said over the life of the modules, powering the case with more power than it’s rated for might diminish the life of the modules to some extent (he was thinking more in terms of overpowering audio equipment like tube amplifiers)–anyone feel free to push back on this, I’m just a messenger here.
I then asked him if I should just go with a power station with an AC outlet and use the power brick the Intellijel cases come with instead of the Krisdonia, which doesn’t have a 15V DC setting. He confirmed that with that option, the power station will be less efficient because it’s providing AC to the power brick (as others have already said here and on Mod Wiggler). So all other things considered equal, the AC power station won’t power my equipment as long as a DC (battery/power bank) option with the same mAh rating.
He ultimately suggested I look for a power bank designed to output 15V DC. After searching a little I did find one:
It’s more expensive but this company actually has a website (unlike Krisdonia), and they use Panasonic batteries, which my friend said are top of the line. I’m going to think about switching over to this unit from the Krisdonia just to play it safe.
Update: Going off a post from @ScottMFR above, I also found this, which also has a 15V setting. Cheaper but not available to ship to the US and only 20,000 mAh compared to the BiX bank’s 60,300 mAh:
