is this safe to use with a generator?
should i use the power board from my home computer?
cheers

just buy a decent sinewave inverter and you dont have to worry.
i got my 1000w sinewave for around $300

Most laptop powerpacks will swallow anythign from 100v to 260v at 50-60hz. In other words, they are pretty tolerant. They convert straight to DC anyway, so apart from big spikes from changing the load too quickly, it should be fine.
You don't need sinewave inverters with decent quality switchmode power supplies.

That would be a modified sine wave inverter. to run most appliances it OK, but more sensitive equipment may not be so happy with you.j-top paj wrote:just buy a decent sinewave inverter and you dont have to worry.

That said laptop power supplies are pretty tough and will cope with relatively dirty power no probs.
" If governments are involved in the covering up the knowledge of aliens, Then they are doing a much better job of it than they do of everything else "
Laptop SMPSUs will run off a wide voltage/frequency range, they will even happily run from 400v DC 
Most generators would be fine - even the cheap GMC ones because they are more or less stable, doesn't matter if the voltage is 10v low or the frequency is 10Hz fast, the SMPSU will be fine.
It's the massive spikes in a waveform distorting under load from cheap MSW inverters that kill laptops and their batteries.
It's correct you don't need a true sinewave inverter to power a SMPSU, but don't use little POS MSW inverters if you can avoid it.

I have heard of some switch mode power supplied not coping with a square wave input from an inverter due to the first stage rectifier diodes not being fast switching types. The high frequency component of the square wave destroyed the diodes. That was a long time ago however, and related to CFL's at the time. The solution was to run them from 240 DC by throwing a good quality bridge rectifier in front of them.
The other thing that could give you problems is if you are running one of these cheap gensets near rated capacity and abruptly switch load on / off. It's easy to induce large spikes from teh coils with relativley large load changes. A 240v fridge cycling would probably be bad. If it's just the laptop and other constant loads, you would hav eto be unlucky to have a problem.
Thanx

In the past I have used an old 1400VA ups that only had one 12V battery .. just hooked it up to the car battery.. dodgy but it worked (only to run a few sets of christmas lights)

Do it you will be fine. Laptop power supplies are pretty tough .. especailly if the main unit is turned off. ( I would happily plug any of my equipement or any of the machines I am responsible for) full time professional computer nerdthunder wrote:its for willowglen..my daughter has a lap top.

I was thinking to charge the computer while it is off.
I was thinking kids get bored too quick and they need something to
occupy them

Sorry, but I couldn't resist.
