| 392330 | 2005-09-30 21:58:00 | I am looking for a car power supply for my Dell Inspiron 6000. I tried Dick Smiths and the one they have does not fit my laptop. Anyone know of an alternative source as Dell don't seem to have them and have yet to reply to my requests. | Big John (551) | ||
| 392331 | 2005-10-01 02:37:00 | Try Jaycar (www.jaycar.co.nz). The alternative, (check DSE as well to see who has them on special) is a 100W or 150W inverter. That produces 230V ac, and you plug your laptop's standard power supply into it. This is cheaper than a DC-DC converter ($50 or $60 versus $112 - $204 at Jaycars). (In Jaycar's site, search for "laptop" to find the "proper" things; and use the Category select of "inverter" for inverters.) |

| 392333 | 2005-10-01 03:41:00 | ;) going for a wardrive BJ? Hey now thats an idea ;) But no, I have a GPS attachment for my PC that connects with TUMONZ and tracks live as you drive. Great for finding those streets you dont know about but need to find in the big smokes. Saves stopping and looking at maps all the time. Just follow the dotted line. |

Thanks, I had not thought of using a 230 inverter. Thats a great idea |

| 392335 | 2005-10-05 07:50:00 | ;) going for a wardrive BJ? Well I got my 230V inverter to from Dick Smith and then went down by Harvey Norman for a look at what games were there. Nothing new so decided to try it out and fired it up and it came up perfect. Next thing up pops the question. There are two wireless networks available. A quick look and one showed it was protected but the other was open and a pretty good signal as well. 54kps connect and it was away. A quick web page test just to confirm and yep fully open. Oh well had to go home so no point in downloadng stuff. Just shows how east it is to find open networks. And the inverter is great. I can plug in a tele as well if I got bored with the laptop. |

| 392336 | 2005-10-05 07:57:00 | What Inverter did you get, Big john? This one? (www.dse.co.nz) Sounds interesting :) My laptop's power unit says 19V 3.42Amps. Does watts = amps x volts? Trying to remember the triangle thing here from school about 20 years ago lol) So that's 65Amps draw? I also see that the input supply to the laptop charger is 100~240V so I guess if the voltage drops it will still work. How is 'inverted' 12V AC Power for charging the laptop, is it as efficient as pure mains power? Sorry about the questions, but this will solve my "going away at Xams without any power" problem :D |

| 392338 | 2005-10-05 09:54:00 | How is 'inverted' 12V AC Power for charging the laptop, is it as efficient as pure mains power? Inverter "modified sine wave" 230v output is not pure, but all the laptop power pack does is convert it to high voltage DC and then high frequency chop it and transform it down again, rectifying to DC (just as a PC power supply does) so the "purity" of the 230v is not an issue, the laptop PSU couldn't care less about the purity within reason. And Watts = amps x volts so your laptop needs about 65 Watts, more like 75 Watts allowing for losses in heat. I use a cheap 100 Watt /150 Watt surge inverter for mobile use, cheap and effective for my 70 Watt laptop. Some TVs have a problem starting from the lower power inverters due to the very high "surge" at turn-on tripping the inverter out. |

You can take the meaty edge off that surge by putting a manual disconnect switch in the degauss circuit if you are dead keen. IIRC 12v/230v models used to disconnect the degauss when on 12 volt supplies and you had to press a button if you wanted it to operate. Could be wrong on that though, it's been a while!!
