Industry and products

mobile storage

Mobile storage is storage that moves to the customer. The term is often used the same way as portable storage. NPSA's mobile self-storage page describes an empty mobile storage container delivered to your location, loaded at your own pace, then moved to a new place. Companies define the term differently.

Why it matters

Some providers use mobile storage for small box-style units and portable storage for steel shipping containers, while others use both for the same thing. A shopper should look at the unit, not the label: its size, material, door type, delivery method and security. A common mistake is to assume two quotes for mobile storage are for the same product. One may be an 8-foot unit and another a 20-foot steel container. Operators should state the size and type in each listing. NPSA's members offer many forms of storage, from small units to large containers and trailers.
