Cool! This might be a good solution to feed my power hungry Sony Behemoth. I swear, the thing sucks juice like water through the Hoover Dam. And my friends lovingly refer to the fan as a “jet engine” and “leaf blower.”
Seriously, this is an awesome device to have on hand for traveling or a long day of meetings. You never know when your laptop will be without a plug and you just need a little more juice.
I REALLY like this, I am in the process of acquiring a new laptop to replace my desktop (I am not dragging this monster on the beach) and now there are finally some attractive alternatives to buying a bunch of what are essentially overpriced bricks in your backpack. What would be even better is if there was a way to hook a few of them together, so put a stack of 3 held together with duck tape and the power should last longer then simply using one at a time. Where the heck is my hydrogen battery now that I actually WANT one? That will be the best!

For PDA’s and Mp3 players that accept 5V inputs, you can create your own. However, the 20 dollar price (if thats for the 4 AAA battery version, it might just be cheap enough to go buy this). Plus this looks a lot slicker than an Altoid box with a bunch of wires sticking out of it.

Has anybody managed to find the version powered by 4 AAA batteries? I can only find the Lithium powered versions.
Thanks.
Or why not never carry anything, other than using better batteries themselves, like the new AA USBCELL Rechargeable batteries available in North America and Europe , or phone cell batteries http://www.usbcell.com/products
