Why it’s winning pockets and hearts
Real owners share how this little astronaut changed their cold-weather game.
My hands are always cold, this is actually life-changing. And my phone never dies on the train now.
Bought it as a cute gift for my girlfriend, but I might steal it. The astronaut is so adorable.
Heats up fast and the display is a nice touch. Only downside: I wish it came in more colors!
I use it on my morning walk and then charge my AirPods at work. Two birds, one stone.
Lasts my entire commute both ways, even on the highest setting. Very impressed.
Gave it as a stocking stuffer and my niece won't put it down. Says it's her fave thing ever.
Great build, love the rose gold. The lanyard is handy. Would buy again.
Used it camping last weekend, kept my hands toasty and topped up my phone. Didn't miss my bulky power bank at all.
Honestly got it for the astronaut. But the hand warmer is legit. Battery lasts forever.
3 steps to toasty hands and a charged phone
Simple enough for anyone to use, right out of the box.
Charge it up
Plug into any USB-C charger until the display shows 100%. Use the included cable or your own.
Adjust your perfect heat
Press the top button to cycle through three temperature levels. The digital screen shows the current setting.
Charge your devices
Connect your phone or earbuds to the USB-A output port. The hand warmer automatically stops heating when you plug in (unless you hold the button to keep heat on).
Proof this tiny thing works harder than you’d think
Specs that translate to real comfort: measurable capacity, lasting heat, and smart safety.
Everything you get in one neat package
No surprises, just the essentials.

You’re out in the cold, and your hands are numb. Disposable warmers are wasteful, chemical heating pads are bulky, and your phone battery is dying faster than your resolve. There had to be a smarter, cuter way to stay warm.
THE TURNING POINT
We combined a high-capacity 10000mAh battery with intelligent temperature control into a pocket-friendly device. Add an adorable astronaut figure, a crisp digital display, and a USB-C charging port, and suddenly you have a hand warmer that’s also your phone’s lifeline.
YOUR NEW NORMAL
