If the pump chatters I suggest you get yourself a large accumulator tank. Put 20 or 30 psi air pressure in it, the pump will run intermittently and never chatter again. The chattering is more than just annoying it a waste of energy and destructive to the pump.
Please do not toss your defective Converters / Inverters / etc. in the trash
The manual for my SureFlow pump has instructions on setting the pump using the screw mentioned above. It says to open a faucet just enough to allow a small stream and adjust the screw untill the pump cycles about every couple of seconds.
When you open the faucet more the pump should then run continuously,

I generally turn the faucet on full, and the pump runs, when I cut it off, the pump stops as well. Sounds like your pump cannot adjust to a changing water supply which may be normal. Adjusting pressure as others have suggested may work for you, good luck.
