The new Higher Capacity AA 2500 mAh rechargeable batteries have greater power capacity but can only be recharged approx 500 times in the overnight mode. Many campers will use these power banks when they’re out in the wilderness. The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. NiMH batteries stay at about 1.2 volts for almost 80% of their discharge cycle. Would highly recommend to anyone who is outdoorsy or is a student in a college setting.
This way, their power bank will be fully charged when they leave, and the charge will last for a long period of time. The white pot-shaped plastic base is home to a 2500 mAh lithium battery (almost twice the capacity of the 1300 mAh Window Charger), from which sprouts an 8-cm (3.14-inch) stem flanked by two green plastic leaves for decoration. Charging via Micro-USB or via the solar panel.

The only reason I gave it 4 vs 5 stars is because of the mah rating. I was not aware from anywhere on the site that the mah hours cannot be directly correlated to battery size on a device. After spending some 30 daylight hours at the window (spread over four consecutive days), however, the Sunflower’s PV panel failed to collect enough energy to give its battery sufficient juice to more than half-charge my smartphone’s almost lifeless 1350 mAh Li-ion battery. Not cool. Im not sure if its possible to recalibrate remotely or if its a complete wash. Being in the military and having to be out in the field for days at a time this with the nomad 7 keeps me charged and in touch. Overall, I still consider this a useful charger for the money.
