I do this with my Iphone on the golf course. Went to frys picked up a lead acid 12v battery, they have a number of sizes i got the 9 amp hour variety, cig adaptor socket, pack of connectors and soldered everything together. Now when golfing I just take usb cig. charger and cable from my car plug everything in and I can leave phone on full brightness running golflogix. Have not needed to charge 12v lead acid batter yet 3 full rounds completed. Obviously for laptop sub inverter for cig charger and you are good to go. I will try charging my laptop from a fully charged 12v lead acid battery and let you know if or how many times it fully charges ]]>Apr 30th 2010 12:47PMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/

If you have a PC, maybe you can try getting a Hypermac and using a cable that connects to the Hypermac and your PC.

Either way, the Hypermac is pretty much your best choice (defiantly for Mac) assuming you can get it to work on a non-Mac [if possible].]]>Apr 30th 2010 3:07AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/
You could always go for http://www.batterygeek.net who provide an adaptor for every computer (every electronics device) - including an MagSafe for about $30. Ive had a couple of these - they work great on PC's. I've had some problems with my rather old mac, but a friend of mine bought one for his and he loves it. I bought the more expesive option, so it has a USB port in it too, so I can basically run everything from this one brick.]]>Apr 30th 2010 5:57AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.alibaba.com/product-gs/52064595/3_7V_60Ah_Polymer_Battery.html]]>Apr 30th 2010 3:14AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/Apr 30th 2010 3:17AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/P.S. i love the hp tm2...its so.....magical......]]>Apr 30th 2010 3:25AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/

The Tekkeon external batteries come with a lot of tips (others can be purchased for around $5-$8 shipped) and can often be charged by your laptop's charger (with the right tip).

I have had a MP3450 for over a year. It works great and I have found Tekkeon's customer service to be very good. I've used mine with a Dell Mini 9, Dell Mini 10 and a Fujitsu U820. I have not tried it (yet) with my new HP tm2t.]]>Apr 30th 2010 5:11AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/i have purchased numerous of every brand out there
(there used to be some good ones from APC, Targus...but are long discontinued)

at this time the ones i find best and "readily available" (i.e. in stock)
are the ones from
http://www.batterygeek.net/Laptop-Tablet-PC-Battery-Packs-s/1.htm

they come in different sizes (from about 60 WH - to something like 800 WH)

to me they seem to be the same batteries as the HyperMac (same Chinese manufacturer - just in black case - which can be sourced directly from alibaba in quantities) but come with a bunch of tips for PC's
and if it doesn't come with your tip most likely they can get a tip for you

i have about 100 of these currently in deployment - i wont say i love their quality - but i will say they are better than any of the others currently available (at least the ones i know about)]]>Apr 30th 2010 6:13AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.powertraveller.com
It's the size of a thin A5 paperback, charges from any adapter (it comes with A LOT of tips/pins to convert any notebook adapter) at any voltage, supplies any voltage upto 24v and comes with a HUGE array of tips and pins for charging mobile devices and laptops (which you can do simultaneously.) It even comes with a cigarette lighter adapter and a neoprene case.
I own one of these and they're extremely handy to charge random mobile phones and gadgets as well as juice up my laptop.
Hope this helps.]]>Apr 30th 2010 7:17AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/Apr 30th 2010 10:49AMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/

CNet has a review on it and they rate it well but if you look at people who've used it, they claim it's pretty bad. Here's the CNet review link: http://reviews.cnet.com/notebook-batteries/electrovaya-powerpad-160/4505-19216_7-30159269.html]]>Apr 30th 2010 12:27PMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/I use a electrovaya powerpad and have been very happy with it. (FYI The version reviewed in CNET is quite old and I only have experience with the newer models)
In particular I have the PowerPad 95. I'm not sure what the total battery life works out to be, but I can say that I was able to use my Toshiba R500 on >10 hour international flights without a problem, and have never had a battery problem during a day away from power outlets. Size wise its about the same size and weight as my R500 (10.6" x 8.2" x 0.6" and 1.8lbs). And yes it has USB ports for charging ipods etc...
I did have one problem with a defective powerpad (it died in 1 day), however my experience with the company was excellent and I had a replacement quickly.
You do need to figure out which adapters to order from them. Their compatibility list is hardly complete, but its usually easy to figure out as manufacturers tend to use only a limited number of voltages and plug styles.

Hope that helps with your decision.]]>Apr 30th 2010 6:55PMhttp://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/http://www.engadget.com/2010/04/30/ask-engadget-best-external-laptop-battery/
