I have never used an electric one but found this review… hope it helps you out some.
Best Value Electric Log Splitter:
We found lots of reviews for the best electric log splitters and 3 models caught our eye as getting the most positive feedback in this calls. The first is the Fisch LS8000 II Electric Log Splitter which several sites say is no longer available, although we found it online at Thelakeshop.com for $520. It gives you 4 tons of force from a 20 amp motor. Owners say you get about 100 splits per hour which is pretty impressive. Will handle logs 2 feet long and up to 1 foot in diameter. If rumors are true and the Fisch electric log splitter is being discontinued, then go with the Ryobi 4 Ton Electric Log Splitter ($379) which we found on Homedepot.com with a 5 out of 5 stars from all the customer reviewers. It features a 1300 watt electric motor, 4 tons of RAM splitting force, and will split up to 20 inch long logs with diameters up to 12″. Owners say the 2 handed operation make it safe to use and the steel construction make it sturdy as well. The two wheels on the unit make it easy to transport around your property as you split up firewood. Owners agree that the Ryobi electric splitter is a “great, affordable, home log splitter”. Lastly, the Pow ‘R’ Kraft 4T Electric Log Splitter ($285) is what Logsplitter.com recommends instead of the Fisch product listed above. The Pow R Kraft is a 1.75 HP electric log splitter that will cut wood up to 20 inches long and 12 inches in diameter. The 4 tons of RAM should be enough splitting force to take on any log pile you have. There is even a video on the website you can watch to see the thing in action.
