Phone chargers are quite literally a must-have accessory. Even though the latest smartphones are designed to have a long-lasting battery life, you’ll likely need to charge your phone at least once a day. To make sure you’re never caught running on 2% battery, be prepared with multiple cables. Keep a cell phone charger in the glove box of your car to use while on the go, one at work, and one at home. If you know you’re going to be out all day, it’s also a good idea to keep a portable power bank on you. That way, you can easily charge up the battery – no outlet needed.
