put several pairs in parallel to give you the 18v but with more 'beef' - will last longer but cost more

a couple of car batteries in series would run it no problem, providing the laptop can regulate the voltage without the adapter - a few volts over should be ok

get a million lemons the stick a nickle coin and a copper coin in the lemons - make an array of series and parrallel connections to get the required voltage/current bob's yer uncle and fanny's yer aunt - green and practical.

would it work with 999999 lemons - waitrose has sold out

Two nine volt batteries in series gives 18v

See if that gives you anything. Could prove expensive.

Different approach

why not set your corp email account to auto forward any mail to your home account, power down the laptop until you need to connect to get corp files and then just post here all day.


Edit: Last point was a bit redundant really

Update

Thanks for suggestions - I have a universal transformer but only goes to 12v


Muppet rooted through the collected assortment of redundant transformers accumulated over the years - result found an old Dell 20v baby

cut off the connector and wires shoved into socket - no joy

Stripped docking station and hard wired onto socket outlet - no joy

Hmmm no meter to check if there is actually 20v coming out ... off to local garage to buy meter... distant recollection that I had to buy a second psu for the Dell as the first died which may be this one... search underway for other one

A muppet "friend" of mine did exactly the same once. "He" had to nip down the Tottenham Court Road first thing to buy a replacement, costing a crazy £99, and has been much more careful since.

A Muppet 'friend' left the AC power supply to laptop at work, said muppet is working from home today but needs laptop to access corporate email & file systems - general surfing activities can be done on home 'puter

How to get 20 volts into charging system of laptop to ensure 'working from home' is as productive as usual -also laptop needs to be left on to pickup emails etc

Lots of lateral thinking needed
