USB cell are rechargeable AA batteries that can be charged from any USB port – I’ve had them for a day or so and they work as expected, exactly like a rechargeable AA, I just don’t need the charger, only my computer – Link.
I use a wireless mouse that needs an AA and also always have a USB charger for my phone, music player, etc. So, I’m pretty happy with the USB cell in the first round of testing. I’ll use them a lot over the next week and report back more.
Here are the specs:
- Rechargeable AA NiMH Battery 1.2v 1300mah
- Built in Intelligent Charger
- Charge by powered USB
- NiMH – Nickel Metal Hyrdride
- 90%+ Charged after 5 Hours by powered USB
- Also rechargeable by approved NiMH charger at 250ma for 7 Hours
As I was posting this one of our makers from the Flickr pool asked if you could use the USB cells to power a USB charger like the one we sell in the MAKE store – sure can. It’s a little recursive, USB charger batteries for a USB charger… but it works as expected.
