In recent years we have seen a demand for lighter and smaller cameras, and manufacturers have responded to that demand, mainly with mirrorless cameras, but despite the concern, on the part of photographers, to have less weight hanging from their necks or shoulders the same has not happened with what we carry in our backpacks. If you are like me, the space in your backpacks is never enough.
I always find something else to take with me. In my case, when I go out to photograph music festivals, mainly festivals that last several days, I cannot forget anything, I have to take everything I need and also take backup equipment, in case something goes wrong.
In these cases, at festivals, one thing that cannot be missing is the battery and battery chargers and here the problem begins, each charger needs a power cord, the battery charger, depending on the model may need a power cord or of an external transformer, if, like me, you work with two cameras, and each camera has a grip with two batteries, that makes 4 batteries in total, which requires at least 2 chargers so that we can charge any battery whenever we need.
