I have so many battery chargers between all my photography cameras, action cameras, flashlights and Ni-MH batteries that after a while they all seem to have a very similar generic and basic quality and feel. Granted, most of these chargers were provided with the cameras or flashlights so they felt cheap.

This K&F Concept 4-Slot Battery was a pleasant surprise for me upon opening the package and feeling it in my hands. My first impression was “Wow!” The fit, finish, and design felt like the price was justified.

It charges 4 batteries! But the best feature, especially for my needs, is that this charger doubles as a power-bank. Rarely do I use up all four batteries on my trips, but I bring them anyway in case I need them. So most of the time two batteries are dead weight in my backpack. I also bring a powerbank for my smartphone and that is also extra weight. Now with this charger I can leave the dedicated powerbank at home and no have to worry about my phone running low.

Lastly, this is nit-picky but I'd love it if the battery status indication reflects the actual positions of the batteries
