You can use the IC2 chainsaw to cut down some trees. However, it seems to only drain battery for breaking a single block, unlike how axes are handled. (Where it multiplies the durability loss by however many blocks broke)

minecraft 1.12.2
mod 1.2.4
does not work with IC2 Chainsaw

But sometimes this mod doesn't work even if your chainsaw have enough power (EU). It is annoyed when you want to cut down jungle tree or dark oak tree. I think there must be something wrong when program change EU to durability.
