30 days from purchase date

I don't know how long the warranty is. I suggest you contact Vevor directly. My Vevor jack was defective. I returned it.

Don't remember. This floor jack did not work out of the box so I returned it!!!

I don’t really know, but this isn't an ideal jack. Spend a few extra bucks , get a better jack. Cheap jack for a high price compared to what you get.

Number of pistons ..... more pistons will mean faster pump rate. If thats what you need. Also means more expensive, larger, heavier and higher maintenance. If you need a smaller jack for small to medium sized vehicles this jack works great.

Single pump jacks have only one hydraulic Double pump has two hydraulic

Higher capacity… hence quicker lift.

The double pump has two oil outlets vs one on the single making it somewhat faster.
