We've seen some damn small phone chargers before, so when one claims to be "the world's smallest", we tend to be skeptical. Yet the Chargerito appears to back up its claim. This minuscule charger attaches to your keyring, and provides everything you need to power up your device, including fold-out prongs and a flip-up Apple Lightning, Micro-USB, or USB-C connector. As an added bonus, the design creates a sort of built-in dock for your phone, so you can still see incoming notifications on the screen from a distance — which is more than we can say for your average wall wart. When folded flat, it's small enough to fit inside that fifth pocket of your jeans, the one you never knew what it was for until now.
