CO2 Inflator Kits with 9X16g or 5 X 16g CO2 Cartridges, Presta and Schrader Valve Compatible, Bike Tire CO2 Pump, Included Insulated Sleeve

I was out on a ride and noticed I must have picked up a small puncture or pinch flat on my gravel bike. Since I like to ride far out on secluded roads, I always carry a spare tube, tools, and this inflator since it's nice and compact. I was able to use this inflator to fill up a 700x45 gravel tube nice and quickly. I like the valve feature for getting the right pressure and the included sleeve since the cartridge gets very cold!

Worked perfectly and was very easy to use.

I should have researched the cartridge capacity before ordering. The container indicates that 16 gram cartridge will fill my 700 x 38 tires to 58 PSI which is just enough. I should have ordered the 20 gram. Definitely need the larger size for mountain bikes.

It works as it should!

What a great alternative to a hand pump when you have to replace a high pressure bicycle tire tube on the road! It's small, convenient and easy to take along. Just be careful to open that valve slowly the first time you use one of these to make sure you don't overfill I especially if you're riding on thin tires.

Got a new ebike and needed something to refill the tubes if I ever got a flat. Didn't want a hand pump or anything battery powered, so I thought I'd get these. Fortunately, I haven't had to use it yet, but looking at it, it looks simple enough. Screw a bottle on, put the insulator over the bottle as it'll get cold when in use, then open the valve and fill the tube.

Haven't had a need to use yet but nice to have a a good price

Great alternative for flats while biking! I carry a spare tube and this item. I ride 14 to 20 miles and should I have a flat away from the home I have the ability to repair on the spot.
