Using OTG USB for Charging an Android Device from Another Device

While unconventional, it’s possible to use OTG USB to charge an Android device from another device, such as another Android phone or a computer. This method, however, requires careful consideration of power delivery and is often more of a temporary solution than a primary charging method.Here’s a step-by-step guide:

1. Requirements: You will need an OTG USB adapter and a USB cable (e.g., a USB-A to Micro-USB or USB-C cable, depending on your devices). You will also need two devices, one to act as the power source (the “charging” device) and one to be charged (the “receiving” device).
2. Connecting the Devices: Connect the OTG adapter to the “charging” device (the device providing power). Then, connect the USB cable to the OTG adapter and the “receiving” device.
3. Checking the Connection: The “receiving” device should ideally indicate that it is charging. The charging speed will likely be slow.
4. Troubleshooting: If the device doesn’t charge, ensure the “charging” device has sufficient battery life. Some devices may have power-saving features that limit OTG power output.

It is important to be aware of the following:

• Power Output: The charging speed will be significantly slower compared to using a wall charger. The power output from another device is typically limited by the OTG standard.
• Battery Drain on the Charging Device: The “charging” device will experience a significant battery drain, as it is supplying power to the other device.
• Compatibility: Not all devices support charging another device via OTG. Some devices may have built-in safeguards to prevent this functionality.

Limitations of OTG USB Power Delivery

Understanding the limitations of OTG USB power delivery is crucial for managing expectations and avoiding potential issues. These limitations stem from the standard itself and the power capabilities of the devices involved.The following factors influence the power delivery capabilities of OTG USB:

• Power Source Limitations: The power source (typically the Android device) has a limited power output. The OTG standard specifies a maximum current that can be delivered through the OTG port, typically around 500mA for USB 2.0 and up to 900mA for USB 3.0.
• Cable Resistance: The USB cable itself has some electrical resistance. Longer or lower-quality cables can result in voltage drop, further limiting the power delivered to the connected device.
• Device Compatibility: Some devices may have power-saving features or limitations that restrict the amount of power they can draw via OTG.
• Battery Drain: When using OTG to charge another device, the “charging” device’s battery drains quickly.

It’s also worth noting:

OTG USB is not designed for fast charging.

The power delivery capabilities are generally insufficient for fast charging. Users should rely on wall chargers or power banks designed for faster charging speeds.These limitations have real-world implications:

• External Hard Drives: Many external hard drives require more power than an Android device can provide via OTG. This is why a powered USB hub is often necessary.
• Charging Other Devices: Charging another Android device via OTG will be slow, and the charging device will experience significant battery drain.
• Peripheral Functionality: Power-hungry peripherals, such as some USB-powered speakers or high-wattage USB lights, may not function correctly or at all when connected via OTG.
