I would love to see more products that utilize USB-PD. I currently own a Pixel C, and have been fine with the one charger. But now I am waiting on my Pixel 2 XL, I will need to expand my charger collection for travel, in the car, at work, etc. The options for chargers that support the PD spec are very few and far between.
Another product I would like to see are magnetic disconnect charging cables.. My kids go through charging ports on their tablets like no other. I have done research on magnetic cables, and can't seem to find any that I am comfortable purchasing. I would feel much better if a reputable company such as Anker released a product like that.
