Smartphones are power-hungry, and if you’re using yours all the time—whether talking, texting, or checking your stock profile—you’ll probably notice that it doesn’t even last a full day. But carrying around a charger can be a drag, especially when you don’t need to recharge from zero—just a little boost. Some of these ultraportable chargers include built-in cables and connectors for maximum convenience. You won’t even notice their minimal extra weight, and you’ll be able to make it through a full workday without plugging your phone into a socket.
