Now here is my question. I have a similar device that takes AA batteries. I have four Eneloop AA batteries rated at "Tyep 2,000 mAh min 1,900 mAh"
I believe from reading that the Energizer unit is an 8,000 mAh unit. So if my present unit holds 4 of the AA batteries is it approximately the same thing? Or, is there some other item to look at. The Energizer unit will run a netbook for about 3 hours. It seems to me I would have a hard time getting 3 hours out of four AA batteries.
you are forgetting volts
the Energizer is 8000mAh @ 5V
aa rechargeables are about 1.4 volts
Volts times amps equals watts
4 AAs in series give you 5-6 volts but still only 2000 mah (because it's in series
6 at max termiinal voltage but it drops to 5 after 2/3 use
so it takes 4 times that (roughly)
So its equivalent to about 16 AA batteries connected in a 4x4 matix
