From numb fingers to a pocket-sized personal heater
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.
Care notes
- Keep dry
Wipe with a soft, slightly damp cloth. Never rinse under water.
- Charge properly
Use the included cable or a certified 5V/2A charger. Avoid cheap gas‑station adapters.
- Let it cool
After extended use, let the device cool down to room temperature before storing.
- Clean the chamber
The heating chamber does not need cleaning. Do not insert objects into the grill.
