CO2 inflators are a quick way to inflate tires on the go. They are made up of a small metal canister filled with CO2. Attached to a nozzle which has a quick release trigger to deliver CO2 at high pressure. The compressed CO2 gas leaves the canister at a very speed when the top is punctured. Allowing the tire to fill quickly. Some of the advantages of using a CO2 inflator are A) they are quick and easy to use, B) require less effort with just one pull on the trigger, C) they weigh less than a pump which btw may require a mechanical or battery operated mechanism to work, and D) they have a lower initial investment. You usually have to buy a valve with 2 cartridges which seems cheaper than a small portable pump.

Why you need a CO2 Inflator when cycling
CO2 inflators are an important component to carry with you at all times if you are an enthusiastic biker. Even if you aren’t, these inflators can save you a lot of trouble on a flat tire.
They can practically enable you to get to your nearest bike repair shop for a quick fix, and you never know when you might need it.
CO2 inflators can inflate your bike tires within seconds. All one has to do is fit the valve onto the canister nozzle and let it flow.
They also require a lot less effort as compared to pumps that require physical pumping while inflating the tire. These inflators weigh less than a pump and are also easy to carry around as they fit perfectly and easily in your back pack or your bike side holder.
These inflators have a low initial investment as most of them come with 2 cartridges along with the nozzle valve holder in the package.
What we look for in our top picks
The inflators we looked at today had to offer a lot and they really redefined what a CO2 inflator can do in terms of reducing hassle while inflating.
All inflators were compatible with Presta and Schrader valves, which are the most common valves on bike tires. Some offered sleeves to insulate the canister while pumping to avoid cold hands, while others provided a textured finish to avoid cold cans. Some had the flexibility to attach to multiple different capacity options when it comes to cartridges while others only came with the inflator head and no cartridge.
All in all, price was kept in mind and there were a lot of appealing options in the CO2 inflators we looked at today.
