XtremepowerUS 1400W Electric Demolition Jack Hammer, 3900 BPM Heavy Duty Concrete Breaker with Point & Flat Chisel Bits, Adjustable Handle, Carrying Case for Concrete, Brick, Asphalt & Masonry

This has been an outstanding power hammer. I have used this to shape cured concrete, to demo solid core concrete block, and to jack hammer a drainage ditch into a rock face along my woodland access road. This hammer is extremely durable. I have used and abused this tool and it just keep running without flaw. Along my woodland path, there isn't any power. To power this tool, I used a 1280W LiFePO4 battery bank attached to a 1000W Inverter. My inverter peaks at 2000W for a few seconds and that was enough to sustain this hammer. This hammer pulls about 900W while fully engaged, but will peak up to 1400W for 1-2 seconds in order to get up to speed. This thing is very straight forward to use, just install the bit, plug it in and you are good to go. I would say this tool is very affordable compared to other jack hammers of equal ability. This tool is heavy, but it is a jack hammer it needs to be somewhat heavy. if you can't lift and hold a standard 16" concrete block for more than 3 minutes, then you probably shouldn't be using a jack hammer.

Works well and easy

This thing is Awesome!! I am using it to bust off concrete from steel poles supporting a heavy structure embedded in 3' deep concrete, and it's so easy. On my first pole before getting this, quickly learned using a chisel, sledge, etc was a very time consuming task. So, bought this, and, it's a few minutes work. So worth it. I've also had a surgically replace (reverse) shoulder and was worried there would be too much vibration, but there really isn't.

The tools itself looks well made and it works, I gave the product review a 4 star, becuase the case was delivered damaged. Based on the quality of the case (material), it won't last too long.

Great item Powerful Definitely worth it

I thought that this was going to be a flimsy product. I was very surprised when I found that this was very sturdy and it operates well. It it is not heavy and it is very easy to use. Noise level and vibration is minimal. This operates just as well as the high end and more expensive jack hammers. I am very pleased with my purchase.

Its very usefull during house renovation.

I love this jackhammer. It’s strong and dorable. I was able to complete my task of rebuilding my yard. I recommend this to anybody that will want one.

Lo use dos veces con uso moderado, ya no funciona y el bobinado estator esta quemado
