BergHeat 20,000 mAh power bank in black with carbon texture

Ridge, Grip, Lodge, Massif, Core and the heated base layer all run on this power bank – anything that heats over USB at 5V and 2A. With 20,000 mAh it lasts about four times as long as the 5,000 by our numbers: around 20 to 24 hours on the Grip, and around 32 on the Ridge on the lowest setting – spread over several days.

  • Multi-day trips with no outlet
  • Long sits in the stand and long shifts outside
  • A backup in the car or pack – charges your phone too

Run times are calculated estimates. They depend on the garment, heat setting and outside temperature.

Power

  • Capacity: 20,000 mAh (74 Wh at 3.7V)
  • USB-A output: 5V / 2A
  • Input: 5V / 2.1A via USB-C or Micro-USB

Ports and use

  • 2 × USB-A output, USB-C and Micro-USB for charging
  • The two outputs share the power – for full heat, one heated item per power bank
  • CE compliant to EN IEC 62368-1

Size and what’s in the box

  • About 5.4 × 2.7 × 1.1 in (138 × 68 × 28 mm), around 14 oz (400 g)
  • In the box: power bank, USB-C charging cable, quick guide

Charge it fully before the trip, put it in your pack or jacket pocket and plug the heated item into a USB-A port. No need to top it up on the way – back on a charger when you’re home.

  • Only use with heated apparel rated 5V and 2A.
  • Not for heated socks – Stomp and Stomp 2.0 run at 3.7V and have their own power bank pair.
  • Keep it dry – ideally in an inside compartment of your pack.

Charges via USB-C or Micro-USB from any standard USB charger. At 20,000 mAh that takes a while – overnight is best.

Frequently asked questions

  • Ridge, Grip, Lodge, Massif, Core and the heated base layer – anything that heats over USB at 5V and 2A. Not the heated socks: they run at 3.7V.

  • By our numbers, about four times as long as the 5,000: around 20 to 24 hours on the Grip, around 32 on the Ridge on the lowest setting. Cold, heat setting and battery age shorten the time.

  • For a day in your jacket pocket, 5,000 or 10,000 mAh is enough. The 20,000 is for multi-day trips, long sits and as a backup in the car – at around 14 oz it belongs in your pack.

  • You can – there are two USB-A outputs. They share the power, though. For full heat, one heated item per power bank is better.

  • At 74 Wh it stays below the 100 Wh limit above which airlines require approval. Power banks go in your carry-on, never in checked luggage. Your airline’s rules take precedence.

  • Yes, but cold costs every battery capacity. Carry it in your inside pocket, close to your body. Charge it indoors at room temperature.
