If you play tennis, then you know why people always bring so many balls during practice or games. You never know when one of your balls will lose enough air pressure to turn into a dud, so having all those extra balls ensure a dead ball won’t ruin your game. Problem is, going through all those dead balls and throwing them away just seems too wasteful. The Boundless Airmaster lets you easily repressurize them back to life.
Styled to look like a tennis ball can, the device can hold a stack of three tennis balls inside much like any regular can, preserving the balls’ internal pressure to ensure they maintain their bounce during use. Unlike traditional cans, though, it’s designed to repressurize the balls when you put them inside. That means, if you have a bunch of dead balls, all you need to do is put them in the container, press a button, and wait for them to repressurize.
The Boundless Airmaster comes with an airtight pressure chamber similar to tennis ball cans, with the compartment fitting up to three tennis balls at the same time. The airtight construction ensures the balls don’t lose pressure the entire time they sit in the compartment, so you can throw them in the duffel bag, transport them in the car, or even take them on a flight knowing they’ll be ready to play as soon as they pop out of storage. Unlike your typical tennis ball can, of course, it’s designed to do quite a bit more.
At the bottom of the device is an integrated electric pump that it uses to repressurize balls on the fly. All you need to do is press the button at the lower section and the electric pump automatically activate, repressurizing the balls inside. It does this automatically, too, with no need to mess with valves or any other accessories. Above the button is a LED indicator, by the way, which glows in red when it’s pressurizing and turns to green when it’s done. According to the outfit, it can properly pressurize a trio of balls in around 50 seconds.
The Boundless Airmaster comes with a companion app that lets you pair with the device over Bluetooth, allowing you to set the desired pressure levels manually. If you’re using the balls for tennis, the outfit recommends 30 PSI; if you’re using it for padel, then they recommend 26. You can also use the app to check the current pressure levels of the balls sitting inside, so you don’t have to test them out to know when they need repressurizing.
An integrated battery powers the pump and Bluetooth connection, by the way, which, the outfit claims, is rated for about a full month of use. You can recharge it via the built-in USB-C port. Other features include a high-strength plastic body, a lid that automatically locks in tight once the chamber is pressurized, a valve release button (you have to press it to open the screw-on cap), and over-pressure protection (so it won’t ruin your ball).
A Kickstarter campaign is currently running for the Boundless Airmaster. Pledges to reserve a unit start at $60.
