Re-Fuel 9 Hour Action Pack Extended Battery for GoPro Hero 13 12 11 10 9 Black, Waterproof 33ft Dustproof Rechargeable Power Bank (6 Hours 4K Recording) Pass Through Power, All Weather Backup Battery

The Refuel Power bank for the GoPro Hero 9 to 13. It supports passthru charging and can power your GoPro for 5 to 9 hours (settings dependent) and is also 100% water proof. Also power banks under-report their power output in most cases, so the GoPro won't detect if it's truly a 5V 2.4A power bank if that happens. This is why you need to install the GoPro Labs Firmware and then ENABLE the TUSB=1 command and make it permanent (otherwise it will work once and then reset back to default next time it's turned on). So you'd use *TUSB=1 Anyway, here's the link to the Digipower Refuel battery pack, I have 2 of them I use with my Hero 13 cameras. https://www.amazon.com/Compatible-Accessories-Waterproof-Underwater-Dustproof/dp/B095XH4GBJ/ref=sr_1_1?crid=YI814O8FHLW8&dib=eyJ2IjoiMSJ9.DebRrbkL9eUu6Abk2Wu1t61EJrCXmDwbbg3l95G6ceYX7U157p54ra2hkQSsVtMXqC2nk64s4_hBKQG5SMX4MyTyY_oZe5RtgLLUYj4au7F1PnowVuVEtvAA7751gkaEFHVnCgNMURgPuvNdYIvUkHlDJhIsfSyVXBbRDTz2KXvioRycAzLKoRhsFcQnHgWXPEjJtSL4m3xIK4HQ6niAj8WNtg1UsNC9-BvETNZbHMw.1-pJsmZTbkuZFSB0cJKakXlO5Rz0TGHc_DBuRXOZh4Y&dib_tag=se&keywords=refuel+gopro&qid=1777391881&sbo=RZvfv%2F%2FHxDF%2BO5021pAnSA%3D%3D&sprefix=refuel+gopro%2Caps%2C246&sr=8-1

These work really well. Not gonna lie I've flooded a couple because I got them too deep, but if you keep them shallow (less than an atmosphere) you should be good for 6 hours. https://www.amazon.com/dp/B095XH4GBJ?ref=ppx_yo2ov_dt_b_fed_asin_title
