The Core SWX USB Battery Eliminator for GoPro HERO4is a power extension cable that lets you power your GoPro HERO4 from a USB power source. It comes with a clear backdoor that attaches to the rear of the camera's Standard Housing and provides rain and splash resistance (but it's not submersible). The backdoor does not prevent visibility of the rear LCD of the HERO4 Silver Edition.

On the camera end, the cable locks into the bus connector on the back of the camera instead of into the camera's USB port, providing for a more reliable connection, highly beneficial in high impact applications. Another benefit of this power solution is that no heat is generated, since what's being used is simply a cable and not a battery, and this reduces the chance of overheating the camera. The cable is 10 ft long.

Although the HERO3 uses the same bus connector, this Battery Eliminator is only compatible with the HERO4.

Q: 1. Just to double check, the battery eliminator will not work if there is a battery in the camera? Ideally I'd like to use this as a battery extender for a pretty specific application, but is that impossible?

A: Yes, remove the internal battery then use this Battery Eliminator.

Q: 2. Will this work with a GoPro Hero 4 Silver?

A: No this will not work on any of GoPro Hero 4 models. The batteries although similar in size are inserted into the GoPro Hero 3 and 4 differently and therefore have the contact leads in different locations. However there is a battery eliminator kit for the GoPro Hero 4 models available here at B&H Photo.

Q: 9. Is the DC to DC step-down converter in the dummy battery box capable of handling input voltage higher than the average USB 5v? I'm hoping it's one of those step-downs that can handle 4.5 to 12 or 19, etc volts in because I want to use this with hard-wired vehicle power instead of a 12v to USB adapter. I'm not interested in adapters - I only want to know if I can feed in higher voltage and it will correctly convert to the 3.7-4V that the GoPro needs.

A: CamDo has a version that will support up to 24V input.

Q: 10. Will this work with the Go Pro Hero 4 Black Edition?
