Probably be enough power, the chain saw is only a 12" blade and those size saws will more often than not only have the 25cc motor anyway unless they are one of the more expensive brands. My main concern would be back up. Who is their warranty agent, where will you take it if it needs something done to it? Aldi have a habit of buying like a container full of one product, selling them all out at a low price for a quick turn over and then possibly never carrying it again. It looks a lot like the same unit that is sold under various names through Home Hardware and Mitre 10. My neighbour has one and so far he hasn't managed to destroy it other than the line trimmer head split when he hit a rock hidden in the long grass. Even from Mitre 10 it took him nearly a month to get a replacement head.
