Modern action cameras are a useful tool for a photographer in that they are compact, robust and weather resistant. However, adventurous users quickly find that battery life isn’t their strongest point. For longer recording durations, such as time-lapse photography, a mains supply or USB battery pack is needed. Connecting an external power supply typically means opening a sealing door which nullifies the camera’s weather resistance.
This article explains the commercial solutions for using a power supply outdoors and also shows step-by-step how to make a custom-fitting water-resistant connector. Additionally, it shows how to make a weather-resistant USB battery pack housing to provide flexibility for powering an action camera.
