External components
In this section, we will discuss external components that will be useful for a penetration tester who is using Kali NetHunter to simulate attacks on a target.
Wireless adapters
As a penetration tester, an essential piece of hardware is an external wireless adapter for executing various wireless attacks on a target network. The following is a list of supported wireless adapters that are compatible with the Kali NetHunter kernels:

Note
Some adapters may not work for various reasons, such as an incompatible kernel and driver – the adapter may not be receiving sufficient power from the Android device; in this situation, a Y-cable with an external power source is recommended.
OTG cables
Additionally, an on-the-go (OTG) cable should be part of your list of components when using Kali NetHunter. The OTG cable will allow USB devices, such as external wireless adapters, to interface with NetHunter.
The following is an image of an OTG cable with an RT5370 mini USB WiFi adapter:
