Let me tell you, this little accessory has completely transformed how I use my GoPro HERO12. No more frantic battery swaps during important shots!

The magnetic USB-C connection is genius - it snaps into place securely while maintaining waterproof integrity. I've used it in heavy rain and even submerged it briefly, with zero issues.

Where it really shines is pairing with a power bank. I recently recorded a 4-hour timelapse of a sunset by connecting to a 20,000mAh battery - something impossible with standard doors.

The only hiccup? The door requires slightly more force to close than the original. It's a small trade-off for the functionality, but worth noting if you're frequently opening/closing.

Pro tip: If you use protective cases, you'll likely need to modify them slightly (I used a Dremel on mine) for proper connector clearance.

At $40, it's pricey for what it is, but the convenience of continuous power makes this my most-used GoPro accessory after the camera itself.
