It’s essential to note that wireless charging is less efficient than wired charging. The tests showed that wired battery banks deliver a device charge with approximately 60 percent efficiency, whereas wireless chargers only provide an average of 46 percent efficiency. Keep this in mind when considering the ecological and monetary costs of wasted energy.
Number 2. Anker 511 Power Bank
A wired connection is currently the most practical option for charging on-the-go until Android phones adopt technology similar to MagSafe. The Anker 511 Power Bank is a sleek and cleverly designed device that’s about the size and shape of a slim stick of butter. It charged a Galaxy S22 Ultra, which was completely drained, to 75 percent in just over an hour, making it ideal if you don’t have much time between flights but need to give your phone a quick boost.
Moreover, it features a built-in plug and pass-through charging capabilities, which enables it to serve as a wall adapter if you ever find yourself in a situation where both your battery bank and phone are dead, but you’re near an outlet. However, it doesn’t include a cable, so you’ll need to have your own cable that can connect from the bank’s single USB-C port to your device.
