Quick answer: Hydrogen Sports Proton is the lightest machine in the current database at 17 lb. Spinshot Lite and the Sports Tutor Tennis Cube are quoted at 22 lb, while Tennibot Partner Lite is 25 lb. But “weight” is not always measured on the same basis.

*Spinshot publishes the comparison weight without the battery installed. Treat the numbers as manufacturer-quoted comparison values, not a lab-controlled weigh-in.
Portability is more than the lightest number
- Car-to-court distance: a 10–20 lb difference becomes real when parking is far from the baseline.
- Stairs and storage: shape, wheels and whether you must lift the machine into a trunk can matter as much as raw weight.
- Battery basis: verify whether a published weight includes the battery, charger or accessories you actually carry.
- Regional support: Proton is especially light, but the manufacturer currently restricts direct shipping/use to the contiguous United States in our source record.
When a heavier machine is still the better portable choice
If you roll from a nearby car to the court, a 33–35 lb machine with a larger hopper may be easier to live with than a lighter machine that needs more refills or lacks the drills you want. Portability should be a veto only when transport is a recurring friction point.
Use the exact model source before buying. Prices, stock, regional shipping and quoted weights can change. Our full table keeps the caveats beside the numbers.
