If you are using the GoPro camera for extended periods, it is better to power the camera with a battery eliminator instead of connecting it to a charger.
CamDo battery eliminators are available to power the camera from AC mains power or DC battery power over a wide range of input voltages.
The battery eliminator snaps into the battery slot of all GoProHero 3 and 3+ models and latches like the GoPro lid for a secure fit.
Using a battery eliminator eliminates two sources of heat. The charging circuit in the camera and the battery itself, which gets warm while charging.
Less heat makes the camera more reliable. Overheating can cause unexpected shut-down of the camera.
A battery eliminator also bypasses the problems that some users have had with the GoPro charging logic causing the camera to freeze and require a reset.
The AC Battery Eliminator includes a 1.1 amp AC adapter (100-240 VAC input) and a coupler (dummy battery) the size of the standard AHDBT-301 battery used in all GoPro Hero 3 and 3+ models. The coupler cable is 10 inches (254mm) long. The adapter output cable is 4'10" (147 cm) long
