USB charger with 4 channels?

[Weylan]

I am looking for a reasonable quality 4 channel USB charger for NMIH AA and AAA batteries.

Any one got any pointers and recommendations?

Most of the ones I've seen have 2 channels. Remember that you can only get 500 mA (2.5 watts) from even a high powered USB port. The most you're supposed to draw without special power negotiation protocols which I've never seen in a charger is 100 mA (0.5 W). With four AA cells you are talking about 24 hour charge time.
