Product Information
Full details
The Topeak Airbooster Nano is designed for road cyclists and commuters who need an ultralight, rapid inflation solution for roadside repairs. Its key benefit is its extreme portability and ease of use, allowing you to inflate a flat tire in seconds during an emergency. The primary caveat is that it requires manual handling of CO2 cartridges, meaning users must carry spare cartridges and exercise caution when handling them to avoid skin contact with freezing metal.

FAQs
Does this work with threadless CO2 cartridges?
No, the Airbooster Nano is strictly designed for threaded 16g and 25g CO2 cartridges.
Can I use this on mountain bike tires?
Yes, it is compatible with Schrader valves, but keep in mind that a 16g or 25g cartridge may not fully inflate a high-volume mountain bike tire to the desired pressure.
How heavy is the unit?
The inflator head weighs only 8.2 grams, making it one of the lightest options available.
Is the protective shell reusable?
Yes, the shell is made of durable material designed to be used repeatedly with different cartridges.
Why is my tire not reaching full pressure?
Ensure you are using a cartridge size appropriate for your tire volume; if you have a large tire, you may need a 25g cartridge rather than a 16g.
Troubleshooting
Air is leaking between the head and the valve.
Ensure the inflator head is pushed firmly onto the valve stem to create a complete seal.
CO2 is not releasing from the cartridge.
Check that the cartridge is fully threaded and the puncture pin inside the head is not blocked.
The inflator feels cold during use.
Ensure the protective CO2 shell is covering the cartridge to insulate your hands.

Setup, Compatibility & Care
To set up the device, ensure your CO2 cartridge is fully threaded into the head before attaching it to the tire valve. This prevents accidental discharge. The unit is universally compatible with Presta and Schrader valves, meaning no mechanical adjustments are required when switching between bikes.
For care, wipe the head clean after every use to ensure no debris enters the seal. Store the inflator in a dry place to prevent aluminum oxidation. If you notice the seal becoming stiff or leaking, inspect the internal O-ring for wear and replace if necessary to maintain a perfect air-tight connection.
