Suggestion for product:
1. plug somewhat bulky, ie a bit difficult to use in camera bag. Since you can change the power plug from country to country, you can take it off, then fly just two parts in the bag around.
2. It would be nice if you would have a connection for charging in the car, such as a USB port or separate socket. But for the price you can not expect good.
Summary: good product with potential for small cost improvements.
