Are you trying to DIY it? Because even if you can figure out how to, it's pointless when amps can run directly off a 7.2V lithium ion and deliver better performance than a bulky powerbank spitting out 5V 500mA. And most USB power supply circuits used for amps only handle 5V 500mA because that's what they can expect out of a motherboard (and even less on other circuit boards, like smartphones) in order to use only one cable for both signal and power. The closest thing to what you want is a Schiit Fulla2 that has a separate USB port for power.

Well yea want DIY and it doesnt have to be powered by powerbank, just i want it to be something rechargeable and with enough capacity to last over 10 hours, also i forgot to say i need it to be portable. Plus i live in EU so shipping from US might be a problem

DIY amps are almost all 9V for practicality since they're easier to source. You're probably better off getting a ~$100 amp from China that natively runs 7.2V Li-Ion and has USB charging, like the Ibasso D-Zero Mk2

 

[scylla007]

any idea how long those on 9V last before you need to change the batery?

My CMOY's lasted about a year.

Hello,

Anyone tried this kind of powebank to run a desktop headphone amplifier?

https://www.amazon.fr/XTPower-XT-16000QC3-PowerBank-Batterie-15600mAh/dp/B07PY4LP5Y

Apparently they can produce up to 20v DC output...

Could be nice

This amp will work:

but it needs a Toshiba laptop adapter, or 5.5mm x 2.5mm tip, like this one:

BTW, this power bank has almost twice the capacity, will work with the amp above at any voltage, and is cheaper:

Thanks for the link for the powebank.

I have a fiio k5 Pro ess which is fed by 15v DC transformer.

If you need more capacity and can pay for it, then check out the video for this power bank:

Ifi zenCan.
Been using since 3 years as a bedside unit.
Just get a decent 5V (preferably 3A) powerbank. Unmatched for it's price.
