If you are just using it for a trim, not a hack, the Ozito power X change one should be OK, it won't be as good or as quick as a Stihl or Shindaiwa units ( I have both) but should still get the job done. One thing to consider when looking is weight, if you aren't used to using them, you will discover muscles you didn't know you have. The Ozito Power X Change one is what I recommended to my Dad, and had a go at his hedge with it last year, It went well for the price, and your arms are probably going to give up before the battery.
