When you receive your new ThermoTorch 3 Hand Warmer and Power Bank, you'll want to know how long it takes to power up. While the device may have a partial charge upon arrival, the manual recommends a full charge before the first use. To charge your ThermoTorch 3, use the included USB cable and plug it into a USB port on a computer, laptop, car charger, or a USB 5V 2.1A Max adapter. The blue LEDs will blink during charging, and once all four LEDs remain solid, the ThermoTorch 3 is fully charged. Although the manual doesn't specify an exact charging time, waiting for all LEDs to stop blinking guarantees a complete charge for optimal performance.
