To get at least two full phone charges, a 10,000 mAh capacity power bank is the sweet spot. Due to power conversion efficiency loss (heat, voltage stepping), a 10,000 mAh battery typically delivers about 1.5 to 2 full smartphone charges depending on your phone's battery size. If you want a comfortable buffer for two guaranteed full charges, a 10,000 mAh high-efficiency pack or a slightly larger 20,000 mAh brick is ideal.
