Xantrex Powerpack 600 Too many broken features:( I just need the battery !!

***** I just jumped my van using the cigarette lighter !!!! No more popping the hood!!!! Added 5/30/9 **** Review on May 25, 2007: I already have the 400 and the 1500 watt models. I read the other feedback before purchasing this 600 watts. Therefore I was not surprised when my powerpack arrived and didn't work properly. Specifically: the radio was always on draining the battery :( Amazon was GREAT at handling the pick-up and sending out a new unit (5 stars to Amazon!) I ONLY want a power SOURCE. I do NOT want a light, radio, clock, compressor or anything that uses power besides what I plug into it. These other features have a LOT of problems. I don't understand why they include broken junk that causes MANY expensive returns. Now the battery capacity readout is incorrect. However I'm not going to return it since the actual unit works and the radio is not always on. The reason I purchased it was the PRICE: $110 shipped. NONE of the Xantrex PowerPacks provide the amount of battery life stated in their descriptions. That said, they still have the best product out there for the money. Since they are VERY portable, idiot proof and safe, I am comfortable letting kids and the elderly use them. Outside, inside, apartments, condos, schools, street fairs, craft shows, you name it and I've used it there. I can jump cars OR keep lights, fan, water pump or fridg running during power outages, AND use plug-in electrical items ANYWHERE I want to - all for the price of some spoiled meat. Until someone else makes a better, less expensive PowerPack, I will continue to buy Xantrex. I understand the need for a LOUD low battery buzzer when the unit is in a basement or other location far from view. Once I get there, I just wish there was a way to turn off the buzzer so I can conserve power AND still use it to the bitter end without bugging my neighbor (its that loud). Then I switch to another PowerPack. The 600 has a LOT more plastic protecting the unit - more than either of my other units. Its much more rugged so I'm glad they learned (hopefully they'll read this feedback and make an even better model ;) And the handle is easier to hold. Its heavy, but if you don't want to carry it, just get a little suitcase cart or throw it in an old rolling suitcase (CHEAP at garage sales, KMart, etc). Voila, not so heavy ;) SO, if you're looking for a safe, cheap source of power, this is the one for you. If you're looking for a power source that does what the they say it does, you'll be disappointed.
