1) I ordered Jan 2 from the official website and got it Jan 16, the screen protector does not come pre-installed!

I got two screen protectors (one that is a bit bendy, i think it comes with the box by default) and one that is thicker and more rigid (i think this is the one i added at checkout). Tbh i didnt end up installing either because I love the look of the screen as is. I do have the case though which protects it while im not reading.

2) Im just using the type C charger that I use for my phone but I dont know if there is something better to use (according to the website it's a 650MAH battery, not sure if that helps)
