eBay has 2 AA 3000mAh NiMH Batteries w/ USB Charger for $3.89 shipped
$4.60
although this is an interesting 'built-in' idea, USB charging takes a long time and the computer has to be on unless you are using a powered USB hub or AC USB charger.
Coupon MAY6OFF might get 6% more off to focalprice btw
The skeptic in me says that since they state a 3000mAh rating on the batteries, that is enough to make me know it's junk right from the get-go.
And as far as the USB batteries, the one reviewer said they got only a 300 mAh rating. lol.
I have no idea why you would get these over conventional quality rechargeable..Pass
Agreed with #3. If a regular NiMh AA has a capacity around 2500 then how can they make a USB-AA with 3000, especially when it looks like 20% of the battery is missing to put on the USB connector and cap???
^ Far more than 20% of the cell length is taken up by the USB plug and whatever they're using for either current limiting or charge termination behind the plug.
500mAH seems about right as one time I saw a similar cell with around that rating, though I'm not seeing the 3000mAH rating that you guys mentioned, anywhere on FP's site.
I own these, well I should say I own 1, 1 came dead, they did refund me half the money. Def worth the money
The USB batteries do not have the 3000 mA rating those are the regular ones on Ebay. The highest capacity AA hit 3000 mA and obviously once the USB plug and transformer are added in you lose a lot of capacity. Besides the 3000 mA ones have high power leakage rates that's why the low self discharge ones tend to be 2000 mA.. The 3000 mA ones are fine for things that suck a lot of juice and you don't expect to sit in the drawer for months and still work. Neither of these are of much use to me, I use mostly Eneloops or equivalent these days. I need them to hold a charge for a while.
