    I know I have pointed this out before to you, but could you please write with real words?
    Not only does what you write look like random letters and numbers at first glance making it hard to read, but if you can't even be arsed to type out the words, why should people spend the effort of helping you?

    Hm... what about an AC power brick?

    Apart from an extended battery the only way to extend "mobile life" s to lug a generator around...
    (or several batteries)
    You can't produce 90W "on the go" any other way.
    (if you use your car, that's the same as a generator)
    If you are in the sahara solar cells may work for charging if you cover a large enoug area.

    Also consider that options differ depending on the laptop.

    I do have to agree to some extent :)

    That's a deal, Butter.

    Using an external powersupply is annoying at best. You will have a cumbersome brick hanging there, have it in your bag and so on.

    Another thing is, that unless the laptop is capable of receiving external power, but not charge the internal whenever external power is supplied, you have a huge loss of energy.

    Apart from the wasted energy purely from a pollution and economical point of view, you also loose quite a lot of energy using a battery to charge another battery, which means you will have to carry around a bigger battery to make up for the loss when recharging.
    Of course, the latter can be made up for by using the external battery _first_, having the internal battery at full charge from the get go, but tat means your "normal" laptop is not a one-piece, but a box with another another box dangling from it.

    In short, what I'm saying is that all things considered you're much better off buying extra laptop batteries. In most cases, they will be much more efficient, both with regards to weight and bulk, but also just plain ease of use.

    My advice would have been a tad different if you were, say, a boater (with no engine) or some such.
