Finding the right cable for DC power

Hello there,

I want to power my Jetson Nano through the DC barrel jack connector to use 10W mode. Sadly, the website and forum only offer verified options for a cable with type A (American) plugs, but I need type C or F because I live in Europe. I found this one searching on Amazon:
https://www.amazon.de/RS-Power-Steckernetzteil-RS-E04J00-S02-Hohlstecker-Schwarz/dp/B07F849K8P/ref=sr_1_9?__mk_de_DE=ÅMÅŽÕÑ&keywords=dc+netzteil+5V+4A+5%2C5mm*2%2C1mm&qid=1581870051&sr=8-9
Would that do the job?
In addition to that, I have the problem that I also want to power my Jetson Nano from a portable power source like a power bank. Finding one that can output 4A is hard though, so I wondered if I can use my current one (output 5V/2.1A) with following USB to DC barrel cable:

In this case, would it still deliver the required 4A to the Nano?

Thanks for the help in advance!

Hi, for those devices that are not validated officially, we have no recommendation. But you can check Ecosystem for some third-party ones in this site: https://elinux.org/Jetson_Nano. Basically 5V@2.1A should be OK to general power-on, only running heavy load needs 4A input.
