There is an electric version of this tool, superior in every way but flying height, the Electric Jetpack.
The Jetpack is limited to a maximum flying height of ~245 meters (blocks) above the bedrock layer. For comparison, the Electric Jetpack is limited to ~185 meters above bedrock.
When refueling a jetpack you will need to put it in a canning machine, along with some fuel cells. You might have to repeat this multiple times to fill it up to the max.
A jetpack uses 6 biofuel cells per refuel. To fuel a completely empty jetpack to the max, you will need to fuel it 4 times. That is 24 fuel cells in total. 24 fuel cells is equivalent to 192 plants (3 stacks)
With coalfuel cells you only need to fuel 2 times to fill the jetpack up (it still uses 6 cells per refuel). That is 12 cells in total. From scratch you will need 98 coal. (Roughly 1.5 stacks)
