TeeBoxx: Finally Leave the Course on a Full Charge
Keep your charge from the first tee to the last green without ditching music and maps

The front nine is full charge. Bluetooth speaker cranking, GPS map pulled up, phone snapped to the cart, everything's working exactly like it's supposed to.
Then you make the turn. Somewhere around hole 12, that same phone that's been mapping your round, spitting out distances and playing music for three hours flashes the low battery warning, but you've still got an hour-plus of golf left. Now you're thinking about your battery instead of your next shot.
That's the problem TeeBoxx solves. I’m not sure if I’d call this nifty device a phone mount, a bluetooth speaker, or a wireless power bank, because it does each of the three as if that’s its primary function.
The magnetic RexxGrip system holds your phone rock-solid over rough terrain, while a Bluetooth speaker plays the music, and the power bank keeps your battery at 100% for the entire round.
Plus, with your phone mounted right to the cart, you can open your GPS app of choice and get the same hole maps and GPS distances you’re familiar with throughout your entire round without checking your battery status.
Just snap your phone in and play.
TeeBoxx Specs

- RexxGrip™ magnetic mount — snaps a phone into place and holds it through bumps, tilts, and rough terrain
- Built-in Bluetooth speaker for clear audio
- Battery rated for 2+ full rounds of continuous use with phone screen on
- Run any app on your phone — GPS, scorekeeping, music, messages
Here's why $179 is the right number instead of the $100 you'd spend on a regular cart speaker: other speakers play music. Some GPS-specific mounts show you the map. Neither one solves the actual problem, which is that your phone runs out of juice around hole 13 no matter which app you're using.
TeeBoxx charges passively the whole round, so whatever GPS app you've already got dialed in — with your saved courses, your yardage history, whatever data you've built up — keeps running without a fight for battery. You're not switching platforms. You're just not losing power to them anymore.
Who it's For
- Cart golfers: this mounts to a cart, so it's built for the rounds where you're riding, not carrying
- Anyone using a phone-based GPS app: since TeeBoxx removes the battery risk that usually comes with running GPS passively for 4+ hours
- Golfers who play music on the course: no more phone dying on the back 9
- Players with history in a specific golf app: don't to switch to a device with its own closed system just to get maps or charging
From the First TeeBoxx to the Last Green
TeeBoxx doesn't ask you to change how you play golf, just how much you think about your phone while you're doing it.
Snap it in on the first tee, and you'll still be at full charge when you tap in on 18.
