Magnetic Avocado Pair for Cold Hands

Two rechargeable warmers snap together magnetically and can run independently or as a set. Each unit holds a 2000 mAh cell for a combined 4000 mAh capacity, giving outdoor walkers, golfers and commuters heat without a wall outlet. The avocado-shaped shells fit a coat pocket and come in a gift box with two charging cables and a manual.

Three Heat Levels With Indicator Lights

Settings reach 104–113 °F, 113–131 °F and 131–149 °F within three seconds of activation. A short press shows battery state through blue LEDs: one light for 1–33 %, two for 34–66 % and three for 67–100 %. Built-in protections guard against over-current, over-voltage, over-temperature and short circuits.

Wind-Resistant ABS Shell and Solar Top-Up

The acrylonitrile butadiene styrene body resists wind and water during camping, hunting or stadium events. Solar charging supplements the 2.5-hour mains charge, extending usable time to 2.5–4.5 hours per side depending on the chosen level.

Questions about this item

How do I charge the HW-03 hand warmers and what is the step users often miss?

Connect each unit to its own supplied cable; both 2000 mAh cells charge simultaneously in about 2.5 hours. The step often missed is using both cables at once so the second warmer is ready when the first runs low.

What part of the HW-03 will need replacement first and when?

The internal 2000 mAh lithium-ion cells in each avocado-shaped unit degrade after several hundred charge cycles; once runtime drops well below the 2.5–4.5 hour range, the entire warmer must be replaced.

At the high setting of 131–149 °F, how long before the HW-03 hits its thermal limit and reduces output?

On high, each warmer delivers 2.5 hours before the built-in over-temperature protection lowers power; medium and low settings extend runtime toward 4.5 hours.
