3A Output Power Bank?
Is there any multi-cell (18650 or 21700) power bank here or other place that have 3 amp output (or higher)?

Having hard time finding.

Need:
5v output
3A or more output (non-QC, need to be able to supply up to 3A or higher regardless if using Qualcomm device or not).

Only 3A device I find on internet is 3A but only if device used is 3A Qualcomm device.

Integrated LiPo will do, but prefer replaceable 18650 or 21700.

I should been more clear. Output need to be USB-A and 3 amp output must be on one USB-A port.

What I find is power bank will say it's 3A output, but will have 2 USB outputs and the 3A is actually spread across the 2 USB ports, so really it's only 1.5A max per USB port.

I need 3A output on one USB-A port.

IIRC USB 3.0 dedicated charging ports provide up to 1.5A.
USB 3.1 can output 3 A but most charger/bank simply use USB type C instead of type A.

You could pick up a small 12v gel battery intended for use in a UPS, then put SKU 9670434 or SKU 9633052 on it.

You play the victim and I'll play the world's smallest violin.
