The second battery for a full day out

The power bank that comes with your heated vest or gloves covers a good part of the day. The EmberThreads Power Bank 5,000 mAh covers the rest: unplug the empty one, plug this one in and keep going – no socket, no break.

5,000 mAh (18.5 Wh) – the same capacity as the power bank included with the vest and touchscreen gloves
Steady 5V / 2A – exactly what heated apparel is designed for
USB-A and USB-C – for the heating cable and for topping up your phone
4-LED charge indicator – check what is left before you head out
Protection circuits against overcharging, short circuits and overheating
Around 4.2 oz (120 g), slim enough for an inner pocket

Why a second power bank

On the vest, one charge lasts eight hours on level one, four on level two and two at full power – measured at 23 °F (−5 °C), worn on the body. The touchscreen gloves run for around five to six hours. That covers plenty of days. A long day by the lake, a ski tour that ends at the hut or a full shift outdoors can take longer. With a second power bank in your pocket you double the run time instead of turning the heat down. And if you wear the vest and gloves together, each one gets its own power source.

5V and 2A – nothing more

For heated apparel, fast-charging wattage is beside the point. What matters is a steady current at 5 volts. This power bank delivers 5V on both outputs – up to 2.1A on USB-A and 2A on USB-C. That is what the vest and touchscreen gloves are built for.

Cold and batteries

Lithium batteries do not like frost. This power bank discharges down to 14 °F (−10 °C) and charges between 32 °F and 113 °F (0 to 45 °C). Keep it in an inner pocket close to your body – it stays warmer there and lasts longer. The inner pocket of the vest is made for exactly that.

Charging and travel

It charges via USB-C at 5V/2A, and the cable is in the box. The four LEDs show the charge level in quarters. It cannot charge and supply power at the same time, so top it up before you head out. At 18.5 Wh it sits well below the 100 Wh limit that applies to power banks in cabin baggage. Power banks never belong in checked luggage.

Yes, via USB-A or USB-C at 5V. It does not support fast charging – it is not built for that.
