CO2 tyre inflators

I've bought a PDW Shiny Object CO2 Inflater and was wondering how far a single CO2 cartridge will inflate a road bike tyre. This is in case I ever have to use one to pump up a spare tube.
Essentially I'd like to know the process of pumping up tyres in the event of a puncture - is it just one or more CO2 cartridges on their own, or CO2 plus using a manual pump based on your experiences.

A single 16g cartridge can get a 25mm road tyre up to a decent pressure - I don't carry a pump, just a co2 cartridge.
Yes that's good advice. On the few occasions I've used the co2, I've emptied the tyre and reinflated properly when I got home.
Don't buy them in blister packs of 2 from a bike shop; go to any online catering supplier and buy them in bulk for a fraction of the price. I had a lifetime's supply a few years ago (box of 32) for £17 + p&p, compared to 2 for £7.99. Shops have to make a living but there's a limit.
I do that but only because I've only ever used the co2 once so still not comfortable without a known backup. The once I did use it was a revelation though.
Ah, good point!
I got one CO2 canister with the inflater and that is threaded as the inflater is threaded so will be fine, but I also ordered a bulk pack of 6 more CO2 cartridges as they were on special offer and I've just checked and they are also threaded. Thanks for the heads up.
Also remember it's always worth checking the previous posts ;-)
Always carry a pump as well by the way...

Worth reinforcing
To counter the endothermic reaction I use 2" of an old inner tube over the cannister when inflating, much cheaper.
Make sure the tube is in the tyre correctly and not pinched by it. A gentle inflation by a hand pump can move the tube as it inflates but a sudden 100psi can make the new tube useless and a waste of a cannister. It happened to me first time I used cannisters.
Another problem I had is....
Inflate the inner tube
Unscrew pump off the inner tube
Pssssst ! The inner core of the valve got stuck inside the pump. 100psi to 0psi in 1 second.
I screwed the inner core back in the valve and tried again, It took me a few attempts to sort out the sticky inner core (used a bit of chain oil in the end). Thankfully it was with a hand pump. If it was a CO2 canister I would have been f**ked.
