I’ve been using the PowerCore II 10000 and what is kinda bugging me more and more is the cable. We should be trying ditch the cables and his little palm size pearl needs to be an All in One solution.
I’ve got of these solar power banks and it has a micro usb cable on one side plus a lightning cable on the other side so it can be used independently.
Or, could something like a retractable cable be added to them somehow. These would need to be wired in one end so you just have the Micro USB, Lightning or USB-C connector available.
You could still have a USB port to connect additional cables if needed.
I think having something like this with either cable would suit the market. People could buy the one that suits their needs. This would be the perfect device for day use. Then pop it on charge at night.
