How do I charge my PinePhone safely?

[thatrandomguy]

Hello,

I just receive my PinePhone CE w/ pmOS on it. I've gone through installation fine and it's all looking good so far, except for one thing:

I am not sure if I can charge the phone with phone chargers I have. I am in the states and I currently use an Xperia XA2 Ultra that I'm planning to flash LOS on.

If it makes you feel better, you can call me a "stupid American" but the fact remains I am not an electrical engineer. I just checked the forum and wiki (grep PinePhone) for mention of what kind of charger I can get for this thing and I either come up to dead links or some external charger....

It's pretty clear there's no way I'll be getting official support for this so I am trying to make sure I don't break something I paid good money for.

Using the red USB cable that came with my phone: where am I able to use this cable to charge my phone? As far as I can tell, the docs says something with 5V is what's supported.

Would this work: https://www.amazon.com/gp/product/B082TZZJZR/

If not, why? Again, I'm NOT an electrical engineer.

TIA
