Tired of swapping batteries mid recording all the time on your Zoom H4n? Need to do long recording sessions whilst still being portable?

This design allows you to mount external power units such as a simple mobile phone 5v powerbank, so you can eliminate the need to swap batteries all the time.

Designed to be used with either a Velcro or elastic strap, Velcro backing or even a combo of both, it also allows full access to existing mounting options and IO ports.

Here is a link to a demonstration of how it works.
