Smart Charger for Lithium-Ion Batteries

as someone who games a lot and relies on various devices, i picked this up hoping it would simplify my charging routine. it works fine for the basics, but it's not the powerhouse i expected. the smart features are there, but they don't feel as advanced as they could be. overall, it gets the job done without any major hiccups, but it's nothing special. i'd recommend it if you're on a budget and need something simple, but don't expect miracles.
- Pros: to be fair, it handles multiple battery sizes without any issues, which is extremely handy for my collection. it's small and portable, making it easy to carry around, and from what i feel, it does a decent job at keeping things safe by not overcharging.
- Cons: i was a bit disappointed that it only has a few slots for charging, so if you have a lot of gadgets, it can feel limiting. the build quality seems a bit flimsy, and it doesn't charge as fast as i'd hoped for something that claims to be smart.
