Great idea aside, there are practical limitations for this USBCELL:
- It is very expensive (about 4 times the cost of a typical AA NiMH cell).
- Its capacity is only 1300mAh (compared to 2000-2700mAh for a typical AA NiMH cell).
- Its charging time is relatively long (5 hours to charge to 90%)
The product description claims that you can also recharge the USBCELL in an "approved NiMH charger" at 250mA for 7 Hours. But make sure that the charger is a 'smart' one. A timer-based 'dumb' charger will badly overcharge the USBCELL, because it treats all cells as having a typical capacity of 2500mAh.
It is true that you don't need to buy a separate charger for the USBCELL. But the economy of scale is stacked against it in any demanding appliances such as digital camera. For the price of just two USBCELL, you can buy a good charger+battery package (such as the Sanyo USB Charger or Sanyo Travel Charger). This way, you get much greater battery capacity and shorter charging time.Read more ›
I started using them with my xbox controller I use to play pc games and so far the experience has been good, I keep two charged or charging while I use the other two because I'm never sure when the other two are going to die and I hate being in the middle of a game and having to search for my stash of regular batteries.
The only complaint I could give is that they aren't easy to get out of the controller, but that's more of a combination of the way the xbox batteries slide in snagging the cap of the battery, more traditionally loaded battery operated devices shouldn't have that problem at all.
I haven't had time to test the longevity and memory effect on the batteries, but so far it beats keeping a stash of batteries on hand, since the computer is right there that I can plug them in and charge them with.

Great batteries. Should not put them in anything that you use constantly. USB charge seems to take awhile to charge.Published 22 months ago by Jesse
