Optimize the equipment you carry by choosing a battery charger that can handle more than one battery pack model.
The key advantage of the chargers in this category, is that they can adapt to almost every camera battery pack in the known universe. OK, so the Canon LP-E6 is the one exception. 3.6, 3.7, 7.2, 7.4 and other voltages in between.
This means that if or when you ever change your camera, you don’t have to replace your mobile charger!
The other advantage is that unlike the charger that came with your camera, that can only be plugged into the wall, all of the chargers in this department are designed to be as mobile as you are. They can plug into a wall, or into a car, or into a solar panel, and some will plug into a USB port.
