Hi again,
Firstly I must say I'm loving this site. Enjoying reading
blogs and all the great stories and information.
As I received so much help with our caravan query I thought I'd ask for help again. Some websites don't help newbies at all but this one is the total opposite. Really looking forward to joining some groups now and maybe meeting some members from the site eventually. Considering the
membership on here.
Anyway, we are on our way to pick up our first ever van. I'm using the laptop atm but its a big beast and my battery is very limited in its use. Before leaving we picked up our side mirrors at Repco and I just bought a Projecta Laptop Power Adaptor. Haven't opened the packet yet and was wondering if anyone has had any experience with them. It's a newish laptop and I dont want to wreck it. Ive checked my DC cord and it says 19v so I gather thats what I set it to. I'd just seen somewhere about it causing the internal battery damage?
Any thoughts? I'll
check back intermittently so I don't run the battery down :)

Selina,
Welcome aboard!
Check the voltage and current specified on the laptop's 240V power supply. You should select that same voltage on the new 12V power adapter and ensure that the new adapter can supply as much current as that specified on the 240V one. I'm not familiar with that particular power pack, but it probably comes with a range of plugs to match different laptops, and these then plug into the power pack. If yours is like that, it is VERY important that the little adapter plugs are connected to the power pack the right way round - they can be reversed deliberately or accidentally. If the original power to the laptop connector had positive in the centre and negative on the outside (or the other way round), then the new one MUST be configured the same way. If in doubt,
check with a meter before plugging into the laptop. And, when you've got it right, suggest mark it, or glue permanently together.
I wouldn't be concerned for the battery (or the laptop) provided you set the adapter to the right voltage and make that connection the right way round.
Cheers
John | J and V

Be careful.
I bought a 3500Ma Projecta charger for my NEC laptop which has a 3500Ma charger.
On about the second use the Projecta blew up and damaged the power supply of my NEC.
I now use a Jaycar 300W pure sine wave inverter to power the genuine charger of the HP that I had to buy to replace it..
A bit more hassle but greater peace of mind.
Apparently Projecta Mas are not as big as NEC Mas.

A 6000ma Projecta will provide enough power for most laptops
As you found out a 3500ma one wont
My advice is get the higher capacity one, the smaller one provides enough power to start the machine but not enough to allow it do do very much without stressing the power supply.
If you are worried about the battery take it out most will run on just external power
I have been running
mine for the last 12 months on a 6000ma one with no worries.
