That makes sense. Feels like a stretch to advertise it as a feature. I would think the use case for this would be to charge up battery and have it in your backpack to slap on when you need it. It is nice you can charge both at once. I suppose that it can charge the iPhone up to 15 watts only if the brick it is attached to is of a sufficiently high wattage. I think they are stretching to include that as a feature bullet point. Overall, I actually like the product quite a bit. Not sure how justifiable the price is when The competition sells a very similar product for less than half the price, but it is nicely designed and would be a convenient piece item to have in a bag.
