I have all I need and gifted a lot already.
Just did a quick day trip down to Santa Monica, only needed my phone but with plenty of Uber time I didn't want to go only with the phone.
I packed a Anker Powerline 3ft, my Powercore 5000 Slim and a non Anker charger because smaller, Anker soundbuds for walking around finding Uber, corded headphones for flight.
I prefer to not lug a quick charge type because bigger, prefer to use sit down time using the Slim, then recharge Slim when near mains.
I still seek a pure end to end USB-C solution from Anker. USB-C charger and USB-C battery.
