Know the battery.
Cell supplier qualification, incoming inspection and documented battery pack checks are part of our planned release criteria.
Safety-led personal warmth
Safety first.
Warmth follows.
Meet Magnetic Duo: split or joined warmth, backup power and a flashlight. Two 5,000mAh modules with LCD status and USB-C PD 3.0, developed with safety at the core.

Safety at the core
Warmth starts
with the details.
Our development priorities: battery quality, controlled heat and a product history that can be traced.
Manage the heat.
Temperature sensing, an independent over-temperature cutoff, and over-current and short-circuit protection are design requirements.
Trace every batch.
We plan model and batch identification linked to manufacturing and inspection records, with clear support and incident reporting.
For her. For loved ones.
Give warmth.
Share the moment.
From a mountain morning to a family walk, the best winter moments are the ones we share.
FOR HER
Her winter. Her way.
Ski-lodge mornings, fresh-air walks and a gift that says “I thought of you.”
FAMILY MOMENTS
Little adventures, together.
Snowy trails, rosy cheeks and time with the people who make winter special.
FOR SOMEONE DEAR
A little care, close at hand.
A gentle winter stroll, a moment to pause and an easy companion for a winter rest stop.

Winter has a place for you
From the slopes
to the last conversation.
Take a warmer break.
Between runs, slow down at the lodge. Snowy views, good company and a little warmth in your hands.
The questions behind a better winter day
Warmth, without
the guesswork.
How long does it stay warm on a winter walk?
A tested runtime is not available yet. The figures in our design brief are test targets, not a promise for a cold day. We plan to report runtime per module and heat setting, with ambient temperature and test conditions. Heating, phone output and lighting draw from the same battery budget.
Does 10,000mAh mean 10,000mAh in each hand?
No. The current design target is two 5,000mAh modules: 10,000mAh combined nominal cell capacity. Each module has its own energy budget. Nominal mAh is not the same as usable USB output energy; the final specification will state each module’s voltage, Wh and measured output.
Does magnetic mean MagSafe or wireless charging?
No. Magnetic Duo refers to the two warmer modules joining for carrying. Wireless charging and MagSafe compatibility are not claimed. Phone power in the design brief is through a cable.
Can I heat my hands and charge a phone at the same time?
This combination is not yet verified. It is also different from heating while recharging the warmer’s own battery. Each combination requires its own electrical and thermal validation. Do not assume either is supported; the final manual will identify permitted modes.
