"I like the updated usb c charging and high mah. Just what I needed for my gear!"
"Solid battery with a nice type C charging port."
"Very nice to have another charging option. Even nicer to have in USB C. Always nice to have other options when your flashlight does not support charging or you don't have a dedicated charger. Batteries would be even nicer if by itself could be used as a power bank using the same charging port. Maybe in the future."
"I have 3 of the Acebeam cells. Two micro USB and one USB C. I don't know where the 3100 mah comes from as through the wrapper I can clearly see that these are 3000 mah Samsung 30q's. That's the reason I use these for extra batteries for my lights that require the longer length. So if you're in the market for 70mm cells, these are about the best deal you will find."
"More batteries for my Acebeam K65, which need high discharge batteries. Recommended."
"Absolutely no issues. Charges quickly and lasts forever. Only batteries I use in my Acebeam flashlights!"
