Your tire light comes on.
You fix it in the driveway.
Air contracts when it gets cold — about 1 PSI for every 10°F drop. That is why the light shows up in October and keeps showing up until spring. Coldsnap lives in the glovebox so the fix takes two minutes, at home, for free.
Coldsnap Cordless Tire Inflator — Fills Your Tire and Stops By Itself
Set the pressure you want. Clip it on. Press start. It reads the tire first, fills it, and stops at the number you set.
Your dashboard waits until you are nine PSI down
Federal standard FMVSS 138 only requires the warning light once pressure has fallen 25% below what the manufacturer specifies. On a car set to 35 PSI, the light does not appear until 26.
So there is a nine-PSI stretch you drive on with no warning at all — longer braking, worse fuel economy, and tire shoulders wearing out early. The light is a last resort, not a gauge.
The gas station pump is not a gauge either
“Most of the time the ending PSI is lower than what I started with.”
“They’ve never worked well enough to be worth the $1.50 to me — I usually end up with less air than I started.”
“I set the machine to fill to 35 PSI. My TPMS sensor showed 40.”
Three steps, about two minutes
Set your PSI

Clip and press
Screw the hose onto the valve, press start, and let go. The LED lights the wheel well.
It stops itself
Coldsnap cuts out when it reaches your number. No overfilling, no watching a needle.

Questions
When will it arrive?
Free shipping on every order, and most land in 7–12 business days. It ships from our overseas fulfilment partner — we would rather say so up front than surprise you.
Will it fit in my glovebox?
Yes. It is 17.7 cm tall and 510 g, roughly the size of a large water bottle, with the adapters loose in the box beside it.
Is it loud?
Yes. It is a compressor in a housing the size of a phone, so the sound has nowhere to go. Owners mention it constantly and recommend it anyway — but you should know going in.
Can I do all four tires?
Yes. It warms up doing a full set, which is normal for a compressor this small — give it a minute between wheels.
What if I do not like it?
Ninety days to send it back for a full refund. No restocking fee, and return shipping is on us.
It is going to get cold either way
