That's a result! Had another look at that link & see that they also do a 20000mAh version which can output 12V, 16V or 19V @3A along with 5V@2A. Perfect for the NUC - I ordered one - saves all the faffing around with battery management pcbs.

Good find John/Nige, just ordered a 19v one myself to see if it will work with the Cirrus7.

I figured even if it isn't perfect for audio, it will be good for recharging phones, tablets laptops.
It's also the top one recommended in all reviews that I have looked at.

it might be good for the cirrus alright, but the difference between single battery into pc and three batteries, brings a huge/massive leap in body and dynamics, id suggest at least the operating system on battery wether that be usb3 or ssd in addition to your 19v

i was going to buy this one myself but id better pursue cheaper options first 12v batteries are not exactly odd or rare,
waiting on fran to test a car battery vs a small 12v SLA which would be a manageable solution if it sounds good

Nige, remind me again, please what your 3 batteries are powering - the Alzheimers, you know?
One powering your OS drive (USB3?) 5V
One powering your music file storage, (SSD?), 5V
One powering the PC via Pico?

good question John I've obviously not mentioned it before!!!!!!!

the pico supplies the 24pin motherboard socket, pico battery supply in here



theres a 12v 4 pin cpu socket on itx, atx and matx motherboards



then the operating system, still having a preference for usb but theres not much in it anymore since going for a separate supply on ssd




having storage on a separate supply will benefit too but its further down on the list of priorities

So let me ask some more Qs, please:
- is the 4 pin CPU socket only providing power to CPU - this is powered from battery?
- the other motherboard socket is supplied by the Pico?
- are the PSes listed in the order of importance for the sound? i.e. CPU, storage, OS or is it CPU OS, storage?
- you mentioned 2 supplies sounding detailed but lacking body & 3 bringing back that body - what was the 3rd PS supplying?

2 car batteries are working off the motherboard and pico (one each)
the third for the operating system the 3 batteries tapped together gave the big lift if memory serves me right. I am considering at least the option of the 5v as it is neat and tidy.Hope the one picked by Nigel off ebay does the biz.
