Jackery will extend the use of your smart phone and other devices. I started toting one a couple of weeks ago after seeing another cyclist using one during a group ride. Works with my iPhone, Ion Speed Pro video camera, and USB rechargeable bike lights. The only tricky bit is remembering to click the on/battery check button once after hooking up the cable.
I use a couple of Lowepro lens pouches Velcro'd across my handlebar to hold the battery pack and other devices I want to keep handy. The charger cable snakes through the bag with the zipper nearly fully closed. As long as it isn't raining it's fine to run while riding. If the weather looks bad I'll use the weatherproof seal on the back of the Ion Speed Pro, and put the phone, battery pack, etc., into ziplock bags. I can still operate the phone touch screen through a ziplock bag.
I have an Anker 10,000mah battery pack with a 3 foot cable in my biking backpack. The lens pouch idea to hook it up to one of the backpack straps is a good idea, thanks. I have some lens pouches lying around for my Olympus mirrorless camera lenses, I'll see about mounting one.

I grew up near NYC for all my life. Luckily when I was young my father brought us into the city often so I never minded driving in Manhattan. Lived in Manhattan & Queens for a few years so I know it decently well. Especially the subway system. But guess what NYC is huge. And the biking infrastructure is over 1,000 miles of bike lanes and greenways. Sorry, don't know most of it.
There is clearly a market for directional assist both in driving and bicycling - hence why GPS apps are so popular in cars and now bicyclists. Glad you know everywhere you want to go, not everybody does. Hence a stupid argument.
