Portable Charger Battery Bank

We recommend using a Portable Charger Battery Bank with at least 20000mAh capacity. This will run your camera and cooling fans almost all day as the fan(s) draw very little power. I’ve recorded five games once and still had power remaining. (your results may vary.)  These can be purchased for $30 to $100, and I’ve had great success with the less expensive ones. I prefer a battery with the new USB C (PD In/Out) and at lease two USB A power outlets.

  • USB-C port powers your GoPro, Mevo, or Smartphone
  • USB-A port powers the cooling fan

For the GoPro 9 and later, we recommend using a USB C to USB C cable and a Portable Charger Battery Bank with a USB C (PD Out) port. USB-C supports the USB Power Delivery (USB PD) specification. The older USB ports can deliver just 2.5 to 15 watts of power, and your GoPro might not operate with that, depending on the firmware version installed. But USB PD can deliver up to 100 watts, more than six times what older USB ports can do.

Anker Power Banks need “Trickle Charging Mode” to work with our cooling fans. The minimum current requirement (the lowest amount of power a device needs to draw from the battery so that it doesn’t turn off) for the Anker battery is about 30mA to 90mA. When the required input of low-powered devices is less than the battery’s minimum current requirement, there will be no current to charge or operate the device.   To activate it, press the button twice. The LED indicator will turn green, indicating that the trickle charging mode is on. It will turn off 2 hours later when unused. You may check out their listings and see if your Anker power bank supports trickle charge mode.
