I just thought I post a quick update to my Tekkeon 1550 + Official Nokia usb->power cable usage. I had said in my previous post that once I got the Nokia cable that the batteries in the Tekkeon started running out of juice pretty quickly and it was pointed out that the Nokia cable pulls more from the charger than the stock cable that comes with the Tekkeon. This allows the Tekkeon+Nokia Cable to actually charge my device as opposed to just keeping it at a constant level.

Well, last week I picked up some Sanyo 2700 batteries and must say - these are incredible!! I was expecting a ~30% increase (my previous batteries were 2000 mAh) in the amount of use I would get out of a fully charger set in the Tekkeon, but instead I'm seeing ~70% increase in the amount of time between recharges I used to have to recharge the batteries in the Tekkeon pack every day because I used it frequently throughout the day to top off my N810 battery. Now with the same amount of usage I'm able to go for almost 3 days before I have to recharge.

If you use your portable battery pack a lot and it can use AA batteries - you've really got to get Sanyo 2700 (I also read that Duracell 2650 are good but can't speak from personal experience).
