I'm trying to decide between the M12 and M18 tyre inflators. Has anyone used both models? Is the M18 worth the price difference, considering it's a bit over double the cost in the UK? I'm mainly looking to use it for occasional top-ups and to keep in my van for emergencies. I already have batteries for both, so I'm open to saving money with the M12 if it's reliable. Any insights would be appreciated!

If it's just for the odd top-up, you’re fine with the M12. It can handle that just great!
I've been using the M12 for a while now. It's great for topping off tires, but my only issue is it doesn't remember the previous pressure setting, which can be a hassle. The M18 can save multiple presets, so that could be handy if you're filling various tires regularly!
Honestly, for rough patches of time, the M12 has been my go-to. I’ve filled my tire from 30 to 40 psi in about 2-3 minutes. It’s portable and serves its purpose well for an emergency kit. No need for the M18 unless you really want the extra features.
The M18 is definitely the better option if you're looking for speed and performance. It's built to handle higher pressures and has a longer duty cycle before it needs to cool down. But if you're just doing some quick top-ups for your car and van, the M12 should work fine too!

Yeah, the M12 does the job for basic needs. It's not as fast as the M18, but for occasional use, it's pretty solid.
