This product (Moixa MXAA02 USBCell) is based on a great idea - the kind of idea that makes you smack your forehead and exclaim "Why didn't *I* think of that!" Basically you take a '2/3 AA' NiMH cell, and attach an USB-powered charger on top of it. Now you've got a rechargeable AA battery that can be charged from any USB port. So you'll never be caught without a battery charger - as long as there is a computer nearby.

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.

I've had four of these for well over a year, they have mostly made for good conversation and I hadn't used them much and honestly didn't ever know when they were charged or not. Mostly figured they would be good for controllers and wireless mice and keyboards.

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.

Verified Purchase
They stay in the charging (solid green) state, and never seem to fully charge (flash green/orange or turn orange) even if left charging for many hours.

i bought these in 2008 to use in low-power items like TV remotes. unfortunately, not only do they have less capacity than full-size batteries (requiring frequent recharge), after a year of intermittent use they completely succumbed to the "memory effect" and will not hold any charge at all. nice idea, but a practical failure.
