Forklift Hangzhou forklift battery voltage is 12V, if you want to load 220V electric fan on the forklift, how to do to be effective?

I think the most cost-effective, but also the most trouble-free way is to buy a 12-volt fan, should be up to more than 100 bucks, or else is to buy an inverter, at that time, there is no guarantee that the electricity generated by your generator can be long enough to use this 220-volt fan. I think you this person's idea is very strange, creative, but also a little bit belong to the kind of people who are full of nothing to do, so I also want to think of a somewhat difficult way for you to refer to, from the engine fan pulley side, install a belt to drive the fan, but this is a little complicated, have to spend a lot of trouble, I think it can still work, can be used for a long time for you to use, the speed is also fast.
