External Battery (Pack) for Laptop

[Nagunae]

WCIF an external battery pack for charging and running a laptop computer and that ideally can be used for charging my cell phone? And how do I make sense of the specifications once I find a place that sells them (so that I can compare between the various models)? Thank you.

I asked about this at 3C and was told that one doesn't exist. Their solution was an extra back up battery which is spendy. Clearly, the small cell phone back up supply units do not work. There is just not enough juice to do the job but I sure like it for my power hungry droid.
My solution for my laptop is plug it in during classes to recharge. Also, I try to find a coffee shop table with a nearby plugin during lunch and 7-11 is always helpful in letting me recharge while I have a beer. I also spotted a guy plugging in on the MRT. There are a few plugins, like one per carriage, but I know that it is discouraged (read illegal) but I have seen it and nobody got outraged.

Enigma, thanks for that. I know they exist (see here: http://www.thebatterygeeks.com/), and I bet many are manufactured by Taiwanese companies. I have no idea how good they work, though, since I've never known anyone to own an external battery pack. They must be sold somewhere!

3C as usual are struggling with the reality that things exist which are not stocked in their stores... external battery packs for notebooks have been around for quite a long time, url below is for online US store that sells quite a few different versions, once you know what your looking for they become easier to find.

Nice site. I actually thought I was being pressured into an extra battery at about 3,000NT. However, I note the prices on the site and the size of the packs. I'm not sure that I would want to spend that amount for something that I can do much cheaper with a simple purchase of an extra battery but . . .
It's nice to know they are available and it could be used if I upgrade my laptop. That's a definite plus. Thanks

Does size matter to you? (get your mind out of the gutter) look at car boosters or jump starters with an ac outlet. Had one that I could plug a coffee machine in and make a full pot on one charge, with a little power left over.
