Are you inflating your packraft with the inflation bag and heading straight to the water?
AlpackaRaft boats are designed to perform at 1.5–2.0 PSI. The inflation bag alone can’t get there. The Pack-A-Pump is the pump AlpackaRaft developed specifically for their valve system — the tool that gets your boat to the right pressure, and keeps it there.
Why a Dedicated Pump Matters
The standard AlpackaRaft inflation method — the inflation bag — creates the boat’s shape but doesn’t reach operating pressure. An underinflated packraft lacks hull rigidity, requires more paddle effort to move, and doesn’t perform the way it was designed to.
For high-performance whitewater models like the Mage and Valkyrie, running at proper pressure isn’t optional — it’s the difference between the boat performing as intended and fighting you on the water.
There’s also a second factor: water temperature. When you put a cold-water-temperature boat in cold water, the air inside contracts. Pressure drops. The Pack-A-Pump is what you use to bring it back up.
What Is the Pack-A-Pump?
The Pack-A-Pump is AlpackaRaft’s own-developed pump — the result of over a decade of looking for the right solution.
The problem was simple: no existing pump hit all the requirements. Ball pumps were light and cheap but incompatible with packraft valves and unreliable. The K-Pump was well-engineered and trustworthy but too large for a backpack. AlpackaRaft built the Pack-A-Pump to fill the gap.
A polycarbonate tube with a direct-thread valve interface — screws directly onto AlpackaRaft valves. Approximately 30–40 pump strokes to reach operating pressure. Sized to fit in a backpack or bow bag.
“Pack-A-Pump: save your lungs for the hike.”
Key Features
Ultralight and compact Designed to be carried on every trip. Fits in a backpack or bow bag without taking meaningful space or weight.
Direct-thread AlpackaRaft valve interface Screws directly onto AlpackaRaft valves for a secure connection and efficient pressurization. No adapters, no workarounds.
Storage space in the plunger handle The handle interior has room for small items — repair kit components, Cargo Fly maintenance tools, or valve caps.
Compatibility — Read Before Buying
The Pack-A-Pump is AlpackaRaft-specific.
- Compatible: AlpackaRaft temper-assist valves from 2017 onward
- Not compatible: AlpackaRaft dump valves or nozzles from 2016 or earlier
- Not compatible: Any other brand’s inflatable boats or valves
There is no cross-compatibility with other valve systems. If you have an older AlpackaRaft, check the production year before ordering.
How to Use It
Step 1: Inflate the packraft using the inflation bag.
Step 2: Thread the Pack-A-Pump clockwise onto the valve.
Step 3: Pump until the boat feels firm — target 1.5–2.0 PSI. Do not exceed 2.5 PSI.
Step 4: Unthread the pump clockwise and replace the valve cap.
Step 5: Put the boat in the water and splash it to initiate tempering. Cold water will cause the air inside to contract and pressure to drop. Repeat Steps 1–4 until the boat holds firm pressure in the water.
Important Safety Notes
Never over-pressurize. Exceeding 2.5 PSI can cause irreversible damage — including rupture — to the hull or Cargo Fly zipper.
Release pressure when you’re off the water. If you’re taking a break on shore, let the pressure down. Heat — especially direct sun — expands the air inside and can cause damage.
Re-pressurize before paddling again. Always bring the boat back to operating pressure before getting back on the water.
Who Needs This
- Mage or Valkyrie owners who want to run their boat at full performance
- Any AlpackaRaft paddler who doesn’t have a way to reach proper operating pressure
- Paddlers who want a lightweight dedicated pump for every trip
- Anyone buying a new AlpackaRaft — this should come with the boat
