There are several solar powered bags on the market right now that include a power adapter. Those bags are really just emergency chargers, which can be useful. dOck bag feels like a charging station, which I personally never liked. Also, how would the bag be used? The plug would never be used except when you are at home, where you would probably take your cell phone or lap top out of your bag for use. When exactly do you plug the devices into the bag? When you put the gadgets in the bag which is probably when you are leaving home or when you come home? If it’s when you come home this assumes you take the gadgets out of the bag to plug them in, which is contrary to the point of the bag. On the go, if you take the gadgets out of the bag, then you have to plug it back in to something that won’t charge until later. It’s an interesting idea but I think it would be a hassle to use.
