You need to purchase a standard USB battery pack in order to use the Smartsuit Pro. It should deliver at least 2A/2000mA from a single output.
The capacity of the battery depends on the operation time you are seeking. You can expect around 5-6 hours of operation at 5000mA, but this can vary depending on the quality of the battery pack therefore we encourage our customers to use high-quality well-known brands.
There is a pocket specifically dedicated to the power bank on the back of the Smartsuit Pro and it is designed to fit batteries around:
4.5 x 2.6 x 0.5 inches
11,5 x 6,6 x 1,3 cm
The front pocket can also hold larger batteries.
