Quick-Change Power Pack (for AA batteries)

The Quick-Change Power Pack holds 8 AA alkaline (single use) or 10 AA NiMH Rechargeable batteries to power the pump in the Backpack or either of the Coolers for 8 hours of continuous operation. Add convenience by carrying a spare Power Pack pre-loaded with AA batteries (not included) with you on the road and save time by not having to replace individual batteries one at a time in the Power Pack.
