I bought a new one and received an item with a number on it, customer support told me it’s a complete new item and not one that someone had returned. I have used it 4 times and so far it has worked fine and very quick to add some air to the tires. It just after 3-4 minutes of use, I can smell like burnt plastic from the inside. Battery life is pretty good. I haven’t changed since I received the item.

I have a wired analog portable tire inflator from Canadian Tire. It emits a noise that suggests it might explode at any moment. It takes approximately 5 minutes to inflate a tire from 25 PSI to 32 PSI. After charging this inflator for about 3 hours straight out of the box, it only took 3 minutes to inflate all four tires from 25.5 PSI to 32.0 PSI. The inflation process was remarkably efficient, with approximately 30 seconds or less required per tire. I am genuinely impressed with its performance.

This is a great device. It is light, powerful and will not exceed the preset inflation pressure. It stops, preventing over inflation. It also shows pressure in Imperial (psi) and metric measurements. Being battery powered it is very portable. The battery is easy to remove for charging.

Je ne savais pas trop à quoi m'attendre comme puissance ou durabilité mais c'est un très bon achat!

Works pretty well for the price point.

Used it like 20 times for bicycle and car tires over a few years. It was in room temperature storage for a year. The battery can no longer be charged, and I can't find a replacement battery. What a waste of money and resource.
