Hand Warmer Power Bank — 10000mAh, 7-Hour Heat, Astronaut
A Hand Warmer That Lasts All Day — and Charges Your Phone
Meet the astronaut-heated 2-in-1 that wraps your hands in 7 hours of continuous warmth, then tops up your devices from its 10000mAh power bank. Finally, cold commutes and dead batteries are a thing of the past.
More than just a hand warmer
Three reasons this outshines the disposable pack and the cheap metal egg.
Real‑time temperature at a glance
A crisp digital screen shows the exact heat level. No guessing, no burning. Dual buttons let you cycle through three gears — gentle warmth for a chilly desk, toasty heat for a ski lift.
Your backup battery in the cold
When your phone hits 1% on a winter hike, this hand warmer becomes a power bank. It charges any USB device — so you keep maps, music, and emergency calls alive.
Explosion‑proof and constant heat
An advanced chip regulates temperature and prevents overheating. The high‑density battery passes safety certifications for worry‑free warmth all winter long.
Real warmth, real words
What happens when people actually get their hands on it.
I’ve blown through three cheap hand warmers that died by lunch. This one got me through a whole outdoor market shift — and charged my phone for the ride home. The astronaut design is just adorable.
Bought the rose gold for my teen daughter. She says it’s the only thing that makes waiting for the bus bearable. I‘ve borrowed it twice. Ordering the white one for myself.
Small enough to live in my coat pocket. The lanyard is great for dog walks — I don’t drop it when I’m holding the leash. Heat is instantly noticeable, not a slow creep.
Looks as premium as the photos. The warmth is lovely. Only wish the lowest setting was a touch cooler — on mild days it's a bit toasty. But the power bank feature has saved my butt twice already.
Gift for my girlfriend who is always freezing. She shows everyone the little astronaut inside. I get boyfriend points every time she pulls it out at a restaurant.
I’m a photographer, my hands get numb on long winter shoots. This tucks into my glove and lasts through the whole session. Took one star off because the charging port cover is fiddly with cold fingers.
My old Zippo warmer was heavy and took forever to heat. This is lighter, cuter, and the LED display tells me exactly where the heat is. 10000mAh is no joke — I forget to charge it for days.
Ordered for a weekend ski trip. Held up beautifully on the chairlift — warm the whole ride up, then used it to charge my AirPods at lunch. The pearl finish looks like a high‑end gadget, not a gimmick.
Perfect stocking stuffer. My sister thought it was an actual space toy until it got hot. Now she texts me when she uses it.
How to use your hand warmer
Charge it fully
Connect the included cable to any USB‑A port. The digital display will light up and show the battery level. A full charge takes about 3.5 hours.
Power on and pick your heat
Press and hold the power button for 2 seconds. Tap the side buttons to cycle through three temperature gears — the display shows your current level.
Warm your hands or charge your device
Hold the warm side against your palms. To use the power bank, plug your phone into the USB‑A output on the side. The hand warmer will prioritize heating while charging.
Attach the lanyard for on‑the‑go
Thread the included rope through the attachment point. Hang it from your wrist or bag so it's always within reach.
Warmth you can measure
No marketing fluff — just what this little device delivers.

Everything you get
From numb fingers to a pocket-sized personal heater
We've all been there: waiting for the train with hands stuffed deep into pockets, or typing at a desk with fingers so cold they forget how to move. Those one-time-use chemical packs? Weak, wasteful, and dead after 20 minutes. This little spacecraft changed everything.
The cold that crept into everything
Winter mornings meant a choice: thick gloves that killed phone dexterity, or icy fingers. Disposable hand warmers were a half-hearted answer — lukewarm at best, useless after an hour, and another thing to throw away.
A tiny astronaut with a huge heart
The heating core — a miniature chrome chamber with an astronaut motif — pumps constant, safe warmth at three adjustable levels. An imported chip inside keeps the temperature steady, so you're never cycling between too hot and too cold. And the 10000mAh battery? It lasts up to 7 hours on a single charge. While it warms your hands, it'll also give your dying phone an emergency boost.
Fits in the palm of your hand
