A portable cooler includes a first semicylindrical member defining a first aperture in a first side and a second aperture in a second side thereof. A second semicylindrical member is hingedly coupled with the first semicylindrical member. A cradle is removably positioned in the first semicylindrical member. The cradle can rotate with respect to the first semicylindrical member within the space defined by the first semicylindrical member. First and second wheels are rotatably coupled with the first semicylindrical member. First and second axles extend through the wheels and first semicylindrical member and into the cradle. The axles allow independent rotation of the cradle, the first semicylindrical member and the wheels to maintain a substantially horizontal rotational orientation of the cradle with respect to the first semicylindrical member.

A travel suitcase assembly includes a suitcase that has a first portion which is hingedly coupled to a second portion. A first closure is coupled to the first portion and a second closure is coupled to the second portion. The second closure is matable to the first closure when the suitcase is closed to inhibit the suitcase from opening. A divider is integrated into the second portion of the suitcase such that the divider defines a primary storage compartment and a secondary storage compartment in the suitcase. The divider is comprised of a translucent material to facilitate contents of the secondary storage compartment to be visible.

A modular luggage system includes a luggage module having a luggage body, a first frame with telescoping arms; a second frame extending perpendicularly from the first frame; a handle; and wheels. The frame with telescoping arms connects modules together. The body has a lid that moves between an open position and a closed position. The luggage body and lid define a storage compartment with sidewalls. The first frame and the second frame connect to and extend along a first sidewall and a second sidewall, respectively. The wheels are mounted on the first frame on the first sidewall. The handle slides from and within the second frame. The luggage body has a load sensor built into the first sidewall to measure the weight of the luggage body and its contents. A display attached to the sensor displays the weight on the exterior of the module. No more overweight luggage and carts.
