| 1123676 | 2010-08-01 05:14:00 | Hi all I need to be able to use a laptop while traveling on a bus. Getting access to the cigarette lighter won't be an issue as it is the bus we will be using for our rep rugby team. Been looking at these and was after some advice; www.trademe.co.nz www.trademe.co.nz www.trademe.co.nz www.trademe.co.nz What would be the best bet for running a laptop? I'm presuming that any 12v inverter is what I am after. We need to be able to make the use of traveling time to carry out video analysis and the laptop battery will not suffice. Any thoughts/suggestions/recommendations gratefuly accepted. Thanks. |

| 1123678 | 2010-08-01 06:03:00 | I wondered that as well but found this www.trademe.co.nz which says truck or bus and is 12v. Can anyone confirm this? Thanks. |

| 1123679 | 2010-08-01 06:36:00 | Tukapa. All those devices run on twelve volts. As somebody said, trucks and buses are often 24 volts. I have seen a truck with 24 volts that had a 12 volt cigarette light but dont know if that is general. Before you spend money needlessly check with the bus company, firstly if the buses do have a cigarette lighter and secondly what voltage it is. Putting a 12 volt inverter on 24 volts lets the smoke out out of it.That is not good. |

| 1123681 | 2010-08-01 10:35:00 | Something like this (www.dealextreme.com)? Takes a 12v input, I'm sure I've seen 12/24v versions... Edit: here's a 12/24v version: www.dealextreme.com |

| 1123682 | 2010-08-01 10:39:00 | Hi Again I guess the problem is whether it is 12v or 24v on the bus. I will have to make a phone call and find out. There seems to be plenty of options for 12v - not so many for 24v. Thanks. |

| 1123683 | 2010-08-01 11:32:00 | There is one way since its a rugby piss trip. Borrow a 6 cylinder sized lead acid car battery and make a wooden box for it put on the floor under the next seat. Run inverter and lap top adaptor from battery, take a battery charger to charge at the motel you are staying at. Maybe if you know who owns the bus ask them to run a wire from the battery compartment thru a window to your seat they can pick 12vdc from the 24vdc system. You may not have enough time to use the lappie as you undoubtedly will be playing drinking games. You will need a minimum of 100watt inverter dont get one of those small ones they are under stress an burn out. Beware of negative dip***** who tell you cant do this you cant do that. |

Any thoughts/suggestions/recommendations gratefuly accepted. Thanks. www.trademe.co.nz this device is CLOSE to what you need but not big enough. the rest are crap. you must check wether the bus lighter outlet is 12 or 24 v, and get an inverter to match that output/input voltage. Also you must check the voltage and amperage drawn by the laptop power adapter. I have a 12 vehicle with 150 amp hours batterys, it does not like running a 20 v 95 watt power adapter off of a high quality 300w inverter, if the battery in the laptop is low or flat. simply because you are trying to take out more than is going in. If I take out the lappy battery and run it on the inverter only it will frequently shut down when the engine goes to idle as it draws to much power. :) |
