inverters

[delicagirl]

Inverters are not the work of the devil.

More powerful inverters can use more standby power when not in use, so switch it off.

Yes you have to consider that they do use power when they are connected and switched on even if nothing is plugged in, so switch it off if you are not using it

Laptop chargers that run off 12 volts are not that economical and that is why they get hot.

:ninja::ninja::ninja:

You could leave the van engine running while you use the laptop.......

my inverter has never been switched on. maybe you mis-read my original figures - my laptop is 19v.

For goodness sake, we've already been over this. I remember telling you that cigar lighter sockets were not suitable for providing power for a long time and that they would overheat. I even explained why. But going from a 12v charger to an inverter won't fix the problem. What you need to do is wire the charger into a switched, fused supply, not connected through a cigar lighter socket. I told you that before too.
An inverter is the last thing you want. They waste power turning 12v to 230v and the laptop adapter wastes more turning 230v into 20v. Just to avoid a bad plug/socket connection. You'd need to insane to consider it.

I must be insane then.:lol-053:

I have fitted a CBE type twin socket(240/12v).The 12v socket is the cigar lighter type and is rated at 10A,it is wired directly to the leisure battery using 2.5mm cable through an in line fuse.My laptop specs are 2.37A @19v and even with prolonged use with a dc/dc converter the plug and socket connection barely get warm to the touch.

NO the supply to your van laptop charger is 12 volts, and in your case is increased to 19 volts, so is in effect is an inverter itself.:wave::wave::wave:

AAARRRGGGHHH I've got a headache now !!!!!

Well the simple thing is you can't get something for nothing.

If you convert your leisure battery voltage say 12 volts to 230 volts there are overheads hence you feel thing getting warm or even hot.

If you have a plug in cigarette lighter adaptor that converts 12 volts to 19 volts the conversion process causes heat and hence additional power consumption.

If you have a brand new TV at home, yes it is wonderful modern technology, but it still gets warm at the back, hence addition energy required to operate it.

As I say if you are on your own and there is no one around to annoy, you could always leave the engine running and that would keep the batteries topped up.

No

An inverter changes 12V DC to (usually) 24 V AC So canhanging both voltage and the nature of the supply
The laptop power supply the "does the opposite" cahnging 240V AC to 19V DC
So an unneccessary and wasteful method

There are many suppliers of Devices for laptops which change 12V DC to 19V DC This must be better !

Maplin for one
power for laptops as well

Not the home mains charger.

I've just read through all this thread, and I also now have a a headache.......c:

This could get sillly but

Power inverter - Wikipedia

Thus as I posted !2V DC Inverter to 240V aC
Power supply Then to 19V DC

12V DC to 19V DC is one device rather than two without requiring DC to AC and back to DC

I will refrain from any further replies on this subject as it will get us nowhere !
I might not be an electrician but I do understand !

Always understood inverters converted dc to ac ?

 

[Nesting Zombie]

LOL LOL LOL, OH MY WORD !,

Inverted Inverters, Converted Converters, 12v-19v-230v. AC-DC & we haven't even got on to Pure Sinewave or Modified Sinewave yet !.

Just out of interest DG, How have you been coping with your Laptop Charging up to Now !, Could you maybe just buy a 2nd Laptop Battery ?.

 

[sparrks]

Always understood inverters converted dc to ac ?

A poor form of ac For more info

 

[jagmanx]

Yes Indeed

A poor form of ac For more info

It may well cause a laptop power supply (240V AC to 19V DC) to fail !

So I read this as another thumbs up for a GOOD 12V DC to 19V DC device !

I think it is important for readers to understand that there is a lot of personal opinions in this thread.

The 12v power socket is used by the World's largest companies in their vehicles and in their products. These products under go testing to ensure that they are safe for long term use. If they were not fit for purpose, then they would not use them.

The main problem is when people use cheap versions of these sockets to power high loads of over 10Amps, like inverters.

Good quality sockets from companies like CBE, installed correctly, will handle the 120w that they are generally rated at. They will do this 24 hours a day. If they could not, then they would not be selling them.

It is important to ensure that the plug is clean and inserted correctly into the socket.

This plug and socket

It's just a CHEAP Chinese version of the Hella Plug and Socket ..

It is in deed but uses very little current/amps,so a cigy socket will be ok with this but not for the big inverters which must be wired direct to battery via a fuse.

A small jump without any convesion and a lot less power used.

 

[Deleted member 9849]

This is the CBE socket I have fitted which is good quality and doesn't overheat when supplying the laptop with a dc/dc converter(12v-19v)for prolonged periods

Because when i bought the van and knew nothing i was conned and overcharged by charlatans and moneymakers who convinced me these were the things i needed ..... this forum and its wealth of advice has been a dogsend to me oops !!! godsend

Well some very interesting thoughts here. the reason i need a laptop is that i write and am a touch typist and need a proper keyboard.

So 10" Tablet with a bluetooth keyboard ( Large as you like ) .. No reason why you have to have a PC. My IMac uses a bluetooth keyboard .. Perhaps you should visit PC World and give the keyboards a bashing .. You can even back everything up to an external hard drive via USB .. Tablet will run off 12v socket using a USB Adaptor ..

lot cheaper to buy a 12v power charger
