Cooler
A cooler reduces size increase. The cooler includes a main container including a refrigeration compartment, and a battery mount set including a first battery mount to which a first battery is attachable and a second battery mount to which a second battery different from the first battery is attachable. The first battery mount and the second battery mount are positioned relative to each other to cause the second battery to be unattachable to the second battery mount when the first battery is attached to the first battery mount and to cause the first battery to be unattachable to the first battery mount when the second battery is attached to the second battery mount.

the first surface and the second surface are transverse,
the first battery mount is on the first surface, and
the second battery mount is on the second surface.
10. The cooler according to claim 9 , wherein
the first surface and the second surface are orthogonal to each other.
11. The cooler according to claim 9 , wherein
the battery mount set includes a first battery mount set and a second battery mount set.
12. The cooler according to claim 11 , wherein
the second surface includes a second surface adjacent to a first end of the first surface and a second surface adjacent to a second end of the first surface,
the first battery mount set includes a first battery mount on the first surface,
the second battery mount set includes a first battery mount on the first surface,
the first battery mount set includes a second battery mount on the second surface adjacent to the first end, and
the second battery mount set includes a second battery mount on the second surface adjacent to the second end.
13. The cooler according to claim 12 , wherein
the battery mount set is configured such that the first battery is attachable to the first battery mount in the first battery mount set and to the first battery mount in the second battery mount set only when the second battery is not attached to the second battery mount in the first battery mount set and to the second battery mount in the second battery mount set.
14. The cooler according to claim 12 , wherein
the battery mount set is configured such that the second battery is attachable to the second battery mount in the first battery mount set and to the second battery mount in the second battery mount set only when the first battery is not attached to the first battery mount in the first battery mount set and to the first battery mount in the second battery mount set.
15. The cooler according to claim 12 , wherein
the battery mount set is configured such that the second battery is attachable to the second battery mount in the first battery mount set and the first battery is attachable to the first battery mount in the second battery mount set when only the first battery is not attached to the first battery mount in the first battery mount set and the second battery is not attached to the second battery mount in the second battery mount set.
