Well, my apologies as I stand corrected. It looks like the company has existed for a while. With the sheer number of "companies" barfing power banks into the supply chain, it's not too difficult to jump to such a conclusion, though. Especially with a round window and button on the side being such common design elements:

https://www.amazon.com/30000mah-Baseus-Portable-Charger-Charging/dp/B08JV4W4NY/ (Yes, I know Baseus isn't a SIXLTR, but you get the idea.)
Also, it's SIXLTR, not SIXLRT, and it's not an acronym.
I personally use Portable Charger 30000mah, Baseus... https://www.amazon.com/dp/B08JV4W4NY?ref=ppx_pop_mob_ap_share
And USB C Charger, Baseus 65W 3 Port... https://www.amazon.com/dp/B083J229RJ?ref=ppx_pop_mob_ap_share
They both work awsome
Not exactly what you're looking for, but I bought this 65w battery pack to keep my neo juiced while on the go- https://www.amazon.com/gp/product/B08JV4W4NY/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1
It doesn't get hot at all. And it can keep you going for a long time. It is heavy and rather large, but it feels safe.
Any 65w charging block should work just fine- that's what you want to look for.
I saw most people recommend that the charger has PD 3.0, along with recommending 65w, but I saw that the charger dock that came with the Win 3 has a voltage of 3.25, and this portable charger has a voltage of 3.8. I haven't had a portable charger before, so would this model be adjustable or is having a slighter higher voltage okay or should I keep looking? I appreciate any feedback and I love this thing, wanna make sure I don't ruin it if I can help it!
Hah, I saw this one: https://www.amazon.com/30000mah-Baseus-Portable-Charger-Charging/dp/B08JV4W4NY
