Mopar 12-Volt Emergency Roadside Tire Inflator With Sealant Injector
It is a very robust and durable inflator. Made in America which is rare for something like this, but very important given that you will be relying on this inflator when you are in desperate need. The quality and reliability of a made in USA product in a bad situation like a flat tire in a bad area at night is worth a lot for your peace of mind especially if it will be in the car of your wife, daughter, etc.
It is easy to use, you can use it for air only or to inject sealant. The reservoir holds enough sealant to seal a large tire or two small tires. You can refill the sealant yourself with tire slime or fix a flat. You can carry an extra bottle of sealant along with it if needed.
