Okay...

What voltage is the class 2 giving the EZ-B?

How many amps is the class 2 power supply supplying to the EZ-B?

Sorry about that I'm getting ready for work but the power supply input 120vac 60hz 14w Output 9vdc 800mA

Hmmm.... 800mah may not be enough... especially since power supply manufacturers have a habit of over estimating their output....

Agreed. 800mah may be a problem. Could you beg, borrow, but not steal another power supply to try to eliminate power as a problem? Something with at least 2 or 3 amp output, and over 6 volts. A LiPo or Nimh battery pack would be ideal to test this.

Ok thanks I'm going buy one this week sorry not being more specific..

Alright then. Get yourself a 7.4 v LiPo battery or a 7.2 NiMH battery pack with at least 1000mah and try again, and report back with your results. Good luck.

@Steve G.... the battery capacity doesn't really matter that much... what's important is the amount of current it can provide... The LIPOs that power the ez robot are only 1300 mah, but can provide a crap load of current...

@Richard.

I know, and fair point. I just didn't want him running out and getting something that will only last a few minutes before recharging. A 1000mah pack is pretty cheap and should get a reasonable run time.

EDIT: And I see your point now. I added too many zeros. Should have read 1000 and not 10.000 mah. Oops. blush
