The GP B421 charger, charges four AA 2100mAh batteries in six hours via USB connection. You can view the charging progress through the LED indicator which displays charging status as well as if any single-use or bad batteries are inserted. Another safety detail is auto power cut-off by using negative delta V and safety timer protection, which helps you avoid over-charging, over- voltage and short circuiting, as well as preventing damage to the battery lifespan.
With four AA 2,100mAh rechargeable batteries included, you're good to go with this optimal charging solution.
