Which energy-drink cans fit?
Measure the actual format instead of relying on brand.
Check the lower diameter
The confirmed diameter range is 2–3.15 inches inclusive. Slim and standard cans can differ; measure the part that enters the fins.
Check the complete seating
A sleeve, unusual bottom shape or partial insertion changes the setup. Remove any accessory only if its maker permits and verify the can reaches its resting position.
Do not infer from the picture
Lifestyle images show a use concept. They are not evidence that every size from an energy-drink brand was physically tested.
