This will greatly depend on the capacity of the power bank you are charging. Assuming ideal conditions (i.e., the Packr is angled toward the sun and not behind a window), the Packr will output at around 600mA.Using the Packr to charge our Jumpr Mini (1,700mAh capacity) may as little as 3.5 hours, while our Jumpr Prime 10400 (10,400mAh capacity) may take around 19 hours to charge.You can see more charging time estimates for different power sources by visiting our Charge Time Calculator page, found under the All Products link at the top navigation bar.
