Characteristics
| Purpose | Let a supported portable device communicate directly with selected USB peripherals |

| Common legacy connector | Micro-USB OTG |
| Host capability | Must be supported by the phone, tablet, or other portable device |
| Typical peripherals | Flash drives, keyboards, mice, controllers, card readers, and some audio devices |
| Power consideration | The portable host may not supply enough power for every peripheral |
| Modern USB-C note | USB-C uses newer role and configuration mechanisms, although products may still market simple host adapters as OTG |
