Whilst standard power banks turn off when the connected device is fully charged these batteries remain on and continue to provide power to ensure the internal battery remains charged and the device operational. 

SeeSense supplies Voltaic “Always On” battery products to a wide range of customers for many different applications. We  extend the battery life of  GoPro and Back-Bone camera systems.  These are deployed in ‘off-grid’ applications including film & broadcast, events, industrial processes, and other procedures where operational time and reliability is important.  We also use Voltaic batteries to supply our OpCam  medical solution and CamDo long term time-lapse systems with sufficient power.
