You are not mistaken about the pneumatic pick of the generator, the power source is wrong.
The air compressor comes with pneumatic tools
The generator comes with power tools
Regarding your question, I can only understand if 800W is enough for power picks used in municipal construction. Generally, the electric peak power is more than 800W. This is already the limit for choosing 800W motor. The working efficiency of the generator is not high, the service life will not be long and it cannot be driven at all when working under high load. 1500W generator.< /p>
