If you’re looking for a portable storage container solution for moving or storing your belongings, you’re likely to come across U-Box® containers by U-Haul and UNITS® Moving and Portable Storage. But which one should you choose? In this complete comparison guide, we’ll go over how UNITS Moving and Portable Storage works and how it compares to U-Box containers.

Key Takeaways

• If you need to cancel your container reservation within 24 hours of your delivery time, UNITS will charge a cancellation fee. U-Box containers have no cancellation fee.
• UNITS containers only have one delivery method and charge a delivery fee. U-Box containers offer free delivery options.

UNITS Moving and Portable Storage Container Size vs. U-Box Container Size

U-Box Container Size

U-Box containers come in one size measuring 5x8x7.5, totaling 257 cubic feet. The container features dual locking latches and multiple vents to prevent mold and mildew buildup. U-Box containers also feature multiple tie-down rings that let you secure your belongings during loading, storage, and transit.

This container is made with a galvanized steel frame and a single-piece roof to combat the elements.

UNITS Container Size

UNITS offers two container sizes for storage: 12’ (768 cu. ft.) and 16’ (1,024 cu. ft.)containers. UNITS sometimes offers an 8’ container size, but it is not available in most  markets or for long-distance moving, nor does it provide measurements for the container on its website.

Like U-Box containers, UNITS containers have a metal frame, sit low to the ground, and feature numerous vents. A great benefit of U-Box containers is that you’re provided 24 rental furniture pads with every container rental to protect your belongings and cushion fragile items, while UNITS provides none.

Unsure how many containers you need? You can simply use the U-Box containers online estimator tool to get the best idea of what you need for your move. If you order more containers than you need, no worries, you’ll be refunded for those containers you didn’t use.

How Do UNITS Containers and U-Box Containers Work?

Both UNITS and U-Box containers are portable storage units that are used for on-site storage or moving local or long-distance. With UNITS, you’ll either pick a 12’ or 16’ container that gets delivered to you by truck. Once you're done loading the container, it’ll be stored at a UNITS facility or on your own property; it can also be shipped around the country.

U-Box containers work similarly, but offer additional delivery and loading options. U-Box can be delivered and loaded by local labor-only movers booked through Moving Help®.  You can easily add Moving Helpers to your U-Box order. You can also pick up a U-Box container on a trailer or load it at a local U-Haul center for free! UNITS containers only give recommendations for local movers that you’ll need to coordinate outside of your order.

UNITS Portable Storage vs. U-Box Container Cost

UNITS and U-Box containers are designed for both moving, local or long-distance, and storage, either at a local facility or on your own property. But costs vary because of the limited locations; UNITS typically charges more for container rental and delivery, and have longer transit times.
