Hand Pump Blackburn Mammoth CO2 Mini Pump by Blackburn — green, portable bicycle CO2 inflator

The Blackburn Mammoth CO2 Mini Pump by Blackburn is a compact, dual-function bicycle inflator combining a manual hand pump with CO2 cartridge compatibility. Finished in green and built for portability, it is intended for roadside use where rapid tire inflation or topping up pressure is required. The design balances a small footprint with practical functionality, offering cyclists a lightweight emergency solution for fixing flats and restoring riding pressure while away from a workshop.

Advantages

The device integrates manual pumping with a threaded CO2 inflator head, giving the user the choice between controlled, steady air delivery and rapid inflation using CO2 cartridges. Its compact construction and low weight make it easy to store in a jersey pocket, saddlebag, or attached to a frame mount. The simple user interface and minimal moving parts reduce maintenance needs and improve reliability for frequent riders and commuters.

Suitable for

• Road cyclists needing a lightweight emergency inflator for rides and races
• Commuters who require a compact pump for daily use and quick repairs
• Gravel and touring riders who want both manual and CO2 inflation options
• Weekend cyclists who prefer a small, portable tool for unexpected flats

When it may not be suitable

Because of its compact size, the Blackburn Mammoth CO2 Mini Pump is not intended as a replacement for a full-sized workshop pump when precise high-volume inflation is required. Long-term use as the primary inflator for frequent high-pressure topping may be less efficient than larger floor pumps. Additionally, CO2 cartridges (if used) are consumables and must be purchased separately.

Key specifications

• Dual-function: manual hand pump with CO2 cartridge compatibility
• Compact, lightweight construction suitable for on-bike storage
• Threaded inflator head compatible with standard threaded CO2 cartridges
• Suitable for bicycle inner tubes and tubeless valves with appropriate adapter use
• Finish color: green

How to use

For manual inflation, attach the pump head to the valve and operate the pump with steady strokes until the desired pressure is reached. For CO2 inflation, securely thread a compatible CO2 cartridge into the inflator head following cartridge instructions, attach the head to the valve, and open the cartridge to deliver gas in short bursts to avoid overinflation. Always check tire pressure with a gauge after inflation and ensure valve attachments are tight to prevent leaks.

What to consider before purchase

• Whether you prefer manual pumping, CO2 rapid inflation, or both
• Compatibility with your valve type and whether an adapter is needed
• Availability and cost of CO2 cartridges if you plan to use the CO2 function
• Storage space on your bike or in your cycling kit for a small inflator

Usage recommendations

Carry at least one spare CO2 cartridge if you rely on rapid inflation, and practice using the inflator at home to familiarize yourself with attaching the head and controlling gas release. Use the manual pump to fine-tune pressure after CO2 inflation and always store the inflator dry to preserve seals and threads.
