Charger for iPhone / Lenovo combo, that so many people use professionally!
I.e. portable (small) charger with two PD usb-c, where the wattage is optimized for iPhones (is that 18watt?) and for Lenovo Thinkpads like X1, T480s and the like (the popular business models) that use 65 watts.
That would be a winner for all business users!
i would like to see a battery bank that has ac output with about 100-120W and dc out that is configurable.
i would also like to see your 5-in-1 USB C Adapter with 4K USB C to HDMI upgraded to be able to do PD pass through at 45-60watts
Fitted low profile case & keyboard for the Apple iPad Pro 11" and others.
An Apple Pencil alternative.
NVMe SSDs.
Right-angle USB-C adapters for tight fits.
Travel power converters w/adapters with emphasis on being low profile and light weight.
An Air Fryer for the Eufy line.
A true travel charger with 2-pin European plugs.
a small 2-port desktop charger with thin power cable.
thin and short USB-C cables.
It has probably already been said but wish they would make rechargable batteries
They are already in the works
Oh great! Looking forward to them 
A power bank that will charge devices when not charging and will turn into a Qi base when it is charging.
Seems like your anker wishlist is coming true!!
I would like to see an Anker charger capable of charging Samsung Note 10 Plus at 45 watts. Yes that means PD 3.0 and PPS. And perhaps add the charging technology to a battery and bundle them together?
If only I could predict lottery numbers as easy 
Something lighthearted but fun.
Something like one of those bracelet chargers that doesnt necessarily have to hold a lot of power, but something that is there for emergencies.
i said “something” way too many times for a post, something to think about.
Thunderbolt 1 dock for mac
Great idea
This is a bit UK-specific, but I have a nice slim laptop, an Arc mouse that folds flat, and a PD charger for it that turns out to be the most cumbersome thing in my bag, because we use 3-pin plugs over here:
What I’d really love is a charger with fold-in pins, such as this:
Sadly, this was panned on Amazon for not providing the power it promises to.
TL;DR: A charger offering 1xIQ and 1xPD with fold-in pins to make it pack flat.
(Apologies for the white images on a white background.)
How about a combined wireless charger that can charge all my apple devices, iPhone, watch, AirPods that is modern and sleek with minimal wires/footprint.
and how about a Apple watch charger that could be charged and fit on a keyring for travelling etc
1ft usb A 3.0 to usb type c powerline 2 or powerline+ or powerline 2+ cable
1ft usb A 3.0 to usb type c cable on the newest line (powerline)
2 packs are always awesome
This one is obvious: PD 3.0 with PPS chargers, both wall and car. That’s necessary to fully charge the 2019 high end Samsung phones (Note 10/+ etc).
They use PPS to charge at 4.5A x 10V. Perfectly usable in a vehicle or wall charger! Can’t wait to see this from Anker.
