Could be loose solder connection(s) from what you stated. If you know how to solder then closely inspect all connections for quality soldering. Then again if you are not familiar with electronic components and repair, I would make use of the factory warranty and ship it back. A good company should cover return shipping costs or at least point you to an authorized service center to take it to. It is still in warranty, being new, is it?

How much does the voltage vary, particularly as a function of load?

It drops from 12 volts to 10 volts.it seens like it's a loose solder joint somewere. Thanks for the help i will find it hopefuly.
