Meet the Universal USB Smart Charger—your new best friend for keeping all those lithium batteries (you know, the 18650, 16650, and even the big guys like 21700 and 26650) juiced up and ready to go. It's not just smart; it's practically genius, with tech that safely charges them up to 4.2V without breaking a sweat. And here's the kicker: it's also a flashlight (because why not?) and a Power Bank for those 'my phone's about to die' emergencies. Whether you're a battery guru or just someone who hates being left in the dark (literally), this little powerhouse is a game-changer.
