TELESIN AllinBox USB Battery Charger for GoPro Hero 12/11/10/9 Black, with High Speed USB 3.0 SD Card Reader Function Waterproof Storage Carry Case for Gopro 12/11/10/9 Original Batteries

I use this when traveling with my GoPro. It stores 3 batteries (Enduro + Regular) and my backup memory cards. I've gone through nearly 3.5 batteries on certain days when vlogging and snorkeling. I swap out battery and memory cards as the day goes on, and it performs perfectly as a storage case. I'll sometimes carry a powerbank and keep it charging in my bag (charges quickly usb-c to usb-c in the case I have an extra long trip. At the end of the day, I'll be able to charge all my batteries to full for the next day - the green light is a helpful indicator to know which batteries are topped up if I have to grab a battery mid-charge.I haven't tested the waterproof functionality, but it has been caught in the rain with no issues.I originally though the regular box shape would be nice, but the soft rubber coating and the string is really nice for dropping it in your bag or carrying it around.

Plug and play unit. Not a fast charger. This unit will standard charge 3 batteries at once. Indicator lights on front, red when charging, green when charged. Can store micro SD card and read micro SD card. Not sure I'll ever use the SD reader slot, but its there if needed. Nice quality. A+

Great accessories and storage for batteries

This little beauty is perfect for recharging the GoPro batteries and storing the SIM card. I throw the whole deal in my kayak and head down the river. It seems to be waterproof, though I have never immersed it. But nothing inside gets wet even though the case has been splashed on.

I'd gotten the GoPro with a horrible value for money and it barely did what it claimed to do.This one is just plain awesome! And it serves as a way to transport your batteries with you when you're on the go. Something the GoPro falls short on.Big recommend.Heads Up: I gave it a high rating for traveling since I don't mind the extra weight. It's not exactly light.Sooooo, that might bother others.

The claim is that it is a High speed USB 3.0 but in fact it is LABELED AS A SLOW 2.0 & MAX TESTED transfer is ~20MB/S on 10GB/s 3.1 port. Has a white connector not blue. ALSO not even close to waterproof. VERY misleading. Most likely will return. (Lastly Bulky yet no storage for cable.) - Are there version I can check for? Maybe I received an older one.

This is a great addition to the Hero 9/10. I had the same one for the earlier heroes and liked it as well. It charges, is compact, acts as a card reader and has notches to store micro sd cards. Perfect multipurpose tool.

I do a lot of long distance SXS trips and I can put my backup batteries in this and keep them ready to go. Charges fairly quickly. It does everything advertised.
