Jetboil is the way to make quick tea and coffee.
Got one in the van , spot on for a pot noodle where ever you are too
there is a lot to be said for diversity .. when the car breaks you can still brew up.
I carry a trangia meths stove in the grab bag and its in whatever car I'm in whenever I'm travelling more than a few Km..

and it contains dog poo bags, water, biscuits etc........ and an RAC recovery card :-)
But back to your inverter needs, your chargers will struggle with even a big power (relatively old) square wave inverter whereas the more modern almost sine wave ones work better. The auto sensing 110/240 chargers are particularly confused by the wave form.
Now I have a very old 2Kw square wave thing that will boil a kettle as long as the engine is running. Of course a traditional kettle doesnt care what shape the wave is, but my soft start grinder trips the inverter out.

Fluro lights also don't like square wave (modified sine wave ) invertors. I have been using only pure sine wave invertors and all seems to be fine. I did tests on invertors years ago for backup power on fishing boats (live bait tanks). These invertors (ups) had to be pure sine wave and generator friendly.

so what is the difference between pure sine wave and modified sine wave ? I got to get this right for my needs, no point in buying twice

ah I see just read up on sine waves interesting stuff

a pure sine wave is as described (if you know what a sine wave is), however a modified sine wave is closer to a square wave pattern. I know what I am trying to say, but getting it accross is difficult. Google sine wave and modified sine wave, there should be some pics. Modified has a higher 'reactive' component

what is this pure or modified I can work it out? http://www.ebay.co.uk/itm/Assembled...009010?hash=item4d599e0132:g:xYQAAOSwKytZFDLv

The product is a modified sine wave inverter

I believe, putting it into simple terms (mainly for me) is that "pure" is a cleaner signal and more appropriate for delicate electronics and modified sine is for everything else. Your research probably showed the pure stuff is roughly twice the price for given power

it is dont milwakee and makita do a 12V charger?

hmm.. in theory yes its inefficient but the losses in modern switching inverters is relatively small, you can easily see that there are of course losses or you wouldn't need heat sinks and cooling fans.
But the convenience of being able to charge up anything that you already have a mains charger for, or anything you borrow etc.. far outweighs the losses.
Lets face it, turning unleaded or diesel into energy to charge a battery drill isnt the most sensible approach but its very often the most convenient way.

All the big boys do one, but they are pretty expensive .
If all your kit is one brand then it's probably sensible to get one, but if it's a mixture then the inverter is the way to go
Hmmm, so the 30 min rating is lower than continuous... so continuous must be less time than 30 mins
Indeed, done a couple of 2Kw inverter installs, we use 95mm2 cable to the batteries and keep the lengths as short as possible preferably under 2m to minimise volt drop. When you're pulling nearly 200amp from the batteries (testing to max and overload to ensure it first warns us then shuts down properly) you need a decent battery bank, usually around 1000AhGood morning 123hotchef.
To boil a kettle on a 12v to 240v invertor is a scary proposition. A normal kettle here in Au is between 1600w to 2000w at 240v. So assuming 100% efficiency (just for arguments sake)
P=IV
2000=I*12 so
I (current)=2000/12
1=166.6amps
That means you will require significant welding leeds from the battery to power the invertor plus the 12v battery will need to be 'QUITE' big
