Spare Battery Pack

Going on an extra-long trek? Don't run out of juice midway! Bring along extra ExtremeMIST® PCS battery packs to ensure lasting cool comfort!

The battery pack lasts at least 12 hours on the lower speeds and at least 5 hours on the highest speed. Please make sure you first check what charging port the pump has before ordering, some pumps have a USB-C port, and some have a Micro USB port. The pumps can only be charged with the cable for their specific port. All Pro Kit batteries will have a Micro USB port. Battery doubles as a Power Bank to charge your phone or gadgets.

The standard USB-C and Micro USB charged pumps are 6600 mAh and Pro Kit batteries are 9000 mAh.

Important: When ordering a spare battery, Make sure you order the right "Generation" Battery. If you have a Gen 1 battery, please call the office at (602) 368-9625 to let us know so we can send you the right battery. A Gen 1 (prior to 2020) battery will damage a Gen 2 PCS Pump. A Gen 2 battery won't power a Gen 1 PCS Pump. (Gen 2 battery has a button with 4 lights on the top as well as a USB port on each side. Gen 1 only has a micro USB port on the left side.)
