Here's a thought, As an adventurest/expeditionest we're always searching for off the trail ideas. I've been having trouble with my Viair compressor as its seen better days.. So would Anker be willing to create a portable air system which could be plugged into a power port or even a portable solar panel.
Along with this, why not have a power generator which uses the wind. A magnetic mount which looks like a small squirrel cage, could be placed on the vehicle while driving, the wind would be forced into the blades which turns a small generator leading to a small power bank or storage system, thus creating a recharging system or station.
Also, seeing how I'm going to be purchasing a new camera, I've always had issues with charging any camera I've ended up with. The camera companies give you a box which the rectangle shamed battery fits into for charging. I'm needed a new way to charge my batteries or a whole new battery for the Canon lineup.
Then there are ths issues of wanting to keep the photograpghs rolling without having to stop. Most cameras today, you need to shut off the camera, remove the battery, mount the battery int he charger and install an allready charged battery back intot he camera. I'd like to have a system when if the battery does get low, I can simply a portable/mounted charging station to the camera and keep going. Sort of like the motorized advance setup with the old 35mm cameras.
but would this mean that Anker would have to create these types of new charging setups for all brands of cameras.. I suspect so and may not be worth it. However, it seems that Anker has isolated themselves by create products just for the iPhone or so I've noticed.
