This bin is 5u tall, and is deep enough to allow other bins to stack on top.
From product photos it looks like it may fit other Tenergy chargers like the TN477U and TN486U, but I'm unable to find dimensions on their website and have not tested it myself. The slot will hold a charger 138mm x 100mm x 24mm (height is only important if you want to stack on top). Corner radius and geometry look similar between photos, but I also can't guarantee that!

The author remixed this model.
I generated a 3x4x5 filled bin, and then cut out space for the Tenergy charger.
