What is the word for object that take lots of time to prepare, and then you can only use them for a very little time? (like Drones)

What is the word for things that take lots of time to prepare (or charge) and then you are able to use them for a short time until you have to prepare (or charge) them again?

For example, Drones take 2 hours to charge batteries and you can use them for only 15 minutes.

Is there a word describing this?
