The SyncBac PRO can be used to pass external power through to the GoPro HERO7 Black camera. Power plugged into the SyncBac PRO’s mini-USB socket is routed through into the GoPro HERO7 Black’s USB C port, via the supplied USB-C link lead.
The GoPro HERO7 Black is very sensitive to power fluctuations from any supplied 5V USB power source, which can result in an unstable camera system. It is therefore absolutely crucial that a high-quality solution is used to prevent power dips and camera crashes, which may result in lost footage.
If you are considering using the power through option running on the mains supply, please refer to GoPro's recommended chargers.
If you prefer to use a battery power bank, please ensure that your battery unit is of high quality and use very short, high quality cables. Ideally 0.5m or less and quality ‘thick’ leads, normally described as ‘high speed’ - the standard GoPro 0.5m USB-A to mini-USB cable is excellent. Minimising voltage drop (loss) in the cable and ensuring that the power supply can cope with the peaky current demands of the GoPro HERO7 Black in operation will reduce the risk of system failures.
We have tested and recommend the RavPower RP-PB41 battery power bank, due to its higher voltage output and stable delivery of voltage. Our customers have achieved very good results with this RavPower RP-PB41 power bank used alongside the the GoPro branded 0.5m USB leads.
Lower quality power banks and longer cables are useful for re-charging purposes ONLY, when the camera is not recording.
