inverter for laptop

Ad, your going to need a pure sine wave inverter for the laptop. If you run a standard one you risk a surge and mashing your laptop.

can you not get a 12v adaptor for it? some companies do them, might be a better alt.

Hi

Can anyone reccomend a good quality inverter for me to put in the landy to run a laptop on?

We had invertors in the fire service for some of the kit, and I thought of using one but when I researched it for solar systems it seems that the sin waves are not pure and bad for some things. You might want to search compatability first, the ones with pure sin waves if you can call it that seemed to be costly.

I browse the tech pc forum, you might want to try there as well.
 
I bought a laptop convertor that steps the power upto 21v (it's adjustable depending on your laptop. and comes with a set of adaptors to fit any Laptop). cost about £25 I think. If it's only for the laptop. It seems silly stepping the voltage upto 240v then using the laptops power supply to step it back down to 18v again..
 
I would go with pikeys suggestion.

You will also find that it takes a lot of power to run a higher wattage inverter. people say bigger is better, but if your only using smaller items there is no need for a 1000w unit. This will only add to the ampage draw on your batts that you can ill afford.

I have a 300w unit that i only use to charge the girlfriends pentax camera battery. I bought it not nowing what i would use it for and so far this is all i have used it for! almost a waste of time.

hi mate

having problems trying to get a sim card that wont cost us a arm and a leg to run, no chance for a pay and go and the cheapest we have been quoted was £45 plus roaming charge!!!!!

Still looking but if we havent got a good deal by then end of the week then it will have to go back to ryder :(:(:(

Any chance of a link?

It does seem silly to go up to 240 only to come back down again. That said, I am not sure I trust my laptop to a £25 charger from E bay!

You could go for an o2 simplicity SIM card £20 per month with a free bolt on of unlimited data in the UK (1 month contract). Add Data Abroad 50, which is an additional £48.95 for 50mb of data regardless where you are. I would have thought you would struggle to do more than 50mb of data per month if the tracker is set-up with a good interval before it sends data back to the server. They do a Data Abroad 10, which is £20 for 10mb.

We are still waiting on our data costs from abroad as they have not yet come through.
 
Use any inverter. Square waves or sine waves the laptop won't care.

The first thing the laptop does is run all the incoming power supply through it's internal power controller, and RECTIFIES it to ultra-smooth DC .

Maplins £20 - £40 depending on output.

I fitted one to run the sheep shears from the inverter in the Defender dash shelf.
Amazing how many people TELL ME I CAN'T plug the 240 volt shears into the Defender.

I just say electricity is electricity, plug it in and shear the daggy bits off the sheep!

So it look like it would be around a extra £840 if we end up going for 12 months and thats a bit to much just for a tracker my good man.
 
Just buy a Maplins £20 inverter and plug the bugger in!

The laptop unit's power supply (between the mains plug and the laptop plug) WILL sort this all out.

The power supply is there to stand guard between the mains supply and the laptop, and it will assume the mains power is lousy quality - which now hardly matters, because the power supply will sort it out regardless.

Probably the first thing it will do is transform the 240 volt AC down to a lower voltage, then rectify it to ultra-smooth DC, then run it past all sorts of surge and spike protection, then run it past some sort of "crowbar protection", and if it's happy after all that it will send the correct regulated DC voltage to the laptop.

If the output from your power supply is AC in any form, it will be low voltage, and all the rectification and quality assurance of the incoming electricity will be achieved IN the laptop.

Maplins .... £20 up depending on the rating.
