Charging a laptop

Always like the water description of electricity.
Explains it in a way people can visualise.

Water and electricity are best kept apart.
If someone cannot understand the basics, it's best they don't mess with it.

Absolutely, plenty of good auto electricians out there who will prevent your pride and joy becoming a heap of smoking ashes. The stored power in a vehicle battery is quite something to see if liberated almost instantaneously

The other thing to be wary of with the adaptors with the twin point multi plugs (adaptor,point and plug are all guestimate terms) is that it is easy to "reverse the polarity" and fry the laptop...................I know this to be true.

Yes. This laptop needs to be set so the barrel connector is centre positive.

And the ridge along one side is just that.........not a minus sign............I know this to be true

But don't be too quick to dismiss the inverter option, if used wisely you can charge multiple things at one time, which is what we do and generally on the move, so the battery is effectively not affected

Whenever we move we charge anything that cant be charged via USB outlets, so both laptops and electric bike battery are the main things

Even when charging is needed while not moving or on hook up, the additional power consumption seems negligible, if you already have an inverter try it and see, my controller displays A's being consumed, from memory the 12V / 19V adaptor which will charge Bev's lap top took about 3A, the inverter takes 4A, if we were to use 2 x adaptors in theory we could be taking 6A where the inverter will still only be taking 4A

I also prefer to use a small (300W) inverter to charge the laptop whilst driving - it's connected to the vehicle battery via an ignition controled relay. I intend to use it to top up a small Dyson hand held too!

I have used that company a few times, if your laptop isn't listed contact them and theyare bound to have a suitable one for you.
I don't bother with eBay ones only a few quid cheaper & I've had them go bang.
