7/14    Do DC to AC power inverters cause any strain / damage to car batteries?
        Would the car battery wear out faster from continued use of the
        inverter?  Specifically, I'm looking at the Xantrex XPower 75 watt DC
        to AC inverter, available on http://buy.com at http://csua.org/u/3m8  If it
        does not damage the car battery or the device, is this a good price?
        \_ no, no, yes
           \_ Thanks for the validation.  Quick search on the web shows prices
              of $28-$29 for that model.  One site also showed 60W continuous,
              75W for 5 minutes, 150W surge for the XPower 75.  However, my
              laptop (Tecra 9100) requires 15V and 5A, so it seems it would
              only get charged for 5 minutes.  Is that the case, or would
              laptop batteries charge on 60W continous?  -op
              laptop batteries charge on 60W continuous?  -op
        \_ discharging your battery will destroy it eventually. loading your
           electrical system while the engine is running is fine, as
           long as your alternator isn't on its last legs.

8/29    I have 2 AA rechargeable batteries. One is at 300mAH and the other
        one is at 600mAH. They used to be 2400mAH. Is there anything useful
        I can use them for?
        \_ How do you know this?

9/11    Is it practical to have, say, a large portion of CA or AZ running
        on solar power? My coworker runs his entire household via solar
        and it got me to wondering what would happen if everyone did this.
        Obviously industrial plants need more power, but could we do away
        with a lot of our polluting plants if everyone went solar? If so,
        then why don't we? What are the technological obstacles, if any?

Satisified customer from NY rated this item 5 of 5 Nice Electronic accessory I bought this because I was sick of purchasing a wall adapter and a car adapter for every accessory I have. I use the Xantrex car adapter for my cellphone, laptop, and anything else that I have in my car. Make sure you have a little spare room near your lighter. It is very useful as I can now just use wall plugs in the car instead of buying a DC adapter for everything I own. It works well and is easy to use, but you will want to check your PC to make sure that it doesn't use up too much power (most PCs should be fine).
