WARMTH + POWER
Two everyday functions.
The supplied product image describes a rechargeable hand warmer and power bank. Charging output and permitted operating modes will be verified on the sample.
Magnetic Duo / Product design
Snap together.
Warm separately.
A magnetic 3-in-1 hand warmer concept: two 5,000mAh modules, LCD battery and temperature display, USB-C bidirectional PD 3.0 charging and a built-in flashlight. Designed around our latest reference silhouette.
MAGNETIC DUO / 10,000mAh COMBINEDWarmth. Power.
Warmth. Power.
A little light.
Two magnetic modules to split or join. LCD status at a glance. USB-C power in both directions. A flashlight for everyday low-light moments. Silver grey and peach pink retain the distinctive metallic details of the supplied reference.
DIGITAL DISPLAY
Clear at a glance.
A front digital display is visible in the reference. The LCD design will show battery percentage, selected heat level and temperature. Sensor location and display accuracy will be validated on prototypes.
QUICK START
3–5 seconds to start warming.
Our quick-start target is initial perceptible warming in 3–5 seconds. Time to the full setpoint depends on conditions and will be measured separately.
Designed around real questions
Useful warmth.
Clearly explained.
These are our development priorities. Sample testing is still required before any performance claim is confirmed.
Even warmth, in both hands.
Independent controls should make a pair useful. Heat distribution and consistency between modules matter as much as a quick start.
To verify Surface temperature maps, hot spots, paired-unit consistency and cutoff response.
How will warmth be tested? →A runtime with context.
A low-setting indoor result does not tell you how long a cold outdoor walk will last. Heating and phone backup share the battery’s energy.
To publish Runtime per module, heat setting, ambient temperature and operating mode.
Understand winter runtime →One pair. Two energy budgets.
The design target is 2 × 5,000mAh, not 10,000mAh per hand. Usable phone-charging energy differs from nominal cell capacity.
To measure Per-module Wh, usable USB output and losses under stated test conditions.
What does capacity mean? →Magnetic carry. Cabled power.
Magnetic joining does not mean wireless charging. USB-C PD 3.0 is a design target; connector shape alone does not guarantee fast charging.
To verify Input/output profiles, cables, phone compatibility and simultaneous operating modes.
Check charging expectations →Easy to hold. Easy to read.
For winter walks and lodge breaks, weight, grip and readable controls matter. The display must make settings and measured values distinguishable.
To evaluate Weight per unit, dimensions, gloved operation, display accuracy and accidental activation.
Find the right fit →A clear path when things go wrong.
Model identification and clear fault reporting should make support easier. Abnormal battery symptoms need a different process from a routine return.
Before sale Publish seller details, support contact, warranty terms and battery return instructions.
Read about support & returns →Five features. One considered design.
Built around
your winter day.
01 / MAGNETIC SPLIT & JOINOne pair.
One pair.
Two independent warmers.
Separate the modules for independent heat control. Snap them together for compact carry. Two 5,000mAh packs provide 10,000mAh combined nominal capacity.
Know your warmth.
Battery percentage, temperature and heat setting in one readable display. Accuracy and sensor placement will be confirmed on prototypes.
Power both ways.
Bidirectional charging and output, with a proposed 18W maximum per module. Final negotiated profiles and device compatibility require testing.
A quick start.
The initial warming target is 3–5 seconds. Full-setpoint time, surface uniformity and real cold-weather performance will be measured separately.
Light when you need it.
A built-in LED adds everyday illumination to warmth and phone power. Brightness, modes and runtime will be published after testing.
Safety remains the starting point
More than
a feature list.
Cell qualification, temperature sensing, independent cutoff and batch traceability are part of the release plan. Performance claims will be supported by measured evidence.

An optional 10,000mAh single-body version can be evaluated alongside the dual 5,000mAh flagship. It remains a proposed variant with a separate specification and validation plan.
Comfort at home.
Heated throws and blankets, developed around thermal distribution, timed shutoff, controller safety and care instructions.
Warmth outside.
Heated gloves, wearable layers and portable seat pads. Each model will have its own battery, exposure and use requirements.
