What wattage for *cheap* electric demo hammer

[cameronwhite]

I've used a cheaper demolition hammer for a similar project, and it held up surprisingly well. For breaking up an old concrete post, I'd lean toward the 3500-watt model for more power, especially if the concrete is thicker or reinforced. The lower watt ones might work for smaller jobs but could struggle with anything tougher. If you’re not sure about the power requirements, I found a kW to Amps calculator on allcalculators.net super helpful to figure out what my tools could handle safely. It made a difference for me when using it on older electrical setups!
