before I got this I had a messy pile of batteries on my desk and was always swapping chargers for different types it was a hassle now with this thing I just pop in whatever I have and it works like magic no more guessing or waiting around it charges things quickly and even lets me power up my other gadgets on the go which is a game changer for my repair work its made my life so much easier and I feel quite confident using it
- Pros: I can vouch that this charger handles all sorts of batteries without any fuss it automatically figures out what type they are and keeps them safe from overcharging which is quite a relief for someone like me who used to worry about that stuff before and the ability to charge two at once makes it super efficient for my DIY projects
