Could i use this box to enclose a small electric fence charger

I've never seen an electric fence charger small enough to fit in this box. I have property with a number of pastures and we use portable electric fences from time to time but the smallest of these chargers are far too large. You couldn't fit a deck of cards into this box. However, there are plenty of larger water-proof enclosures around and there are portable fence chargers that are waterproof.
