How Does Reverse Charging Work on OPPO Phones
Imagine your OPPO phone acting as a mini power bank for another device when that device runs out of battery. That’s what Reverse Charging allows you to do. With this feature, you can transfer power from your charged OPPO phone to another device over a wired connection—useful especially in emergencies, so knowing how it works and how to use it safely can help you make the most of it.
What You Need to Know Before Trying Reverse Charging
To use reverse charging on your OPPO phone, it needs to meet two basic conditions:
Support for OTG (On‑The‑Go) — This lets your phone act like a host and supply power through USB.
A Type‑C USB port — This is the connector used for most modern OPPO devices.
How to Use Reverse Charging on OPPO Phones
Before you begin, ensure you have the following:
Your OPPO phone with sufficient battery.
The other device that needs charging.
A reverse charging cable or an OTG adapter + USB cable (these are usually sold separately).
There are two common methods:
Method 1: Using a Reverse Charging Cable
Go to [Settings] > [Accessibility & convenience] / [Additional Settings] / [System Settings] .
Turn on [OTG Connection] on your OPPO phone.
Connect the reverse charging cable—make sure the OPPO phone is supplying power (OTG on) and the device receiving charge has OTG turned off.
The device should begin charging.
Method 2: Using OTG Adapter + USB Cable
This method allows you to reverse charge even if you don’t have a dedicated reverse charging cable.
Attach the OTG adapter to your OPPO phone.
Plug a USB cable into the OTG adapter.
Connect the other end of the USB cable to the phone or device needing power.
Ensure the OTG adapter is on the device that has battery, and the cable goes to the low-battery device. The device with low battery should not have OTG active.
Common Questions & Troubleshooting
Does my phone need a minimum charge to reverse charge?
No, reverse power output does not require a minimum battery threshold as long as the phone has some power.
When does reverse charging stop?
It stops when your OPPO phone is turned off, or when the other device is fully charged.
Why doesn’t my other device charge?
It could be the cable’s resistance. If the cable’s resistance is over 250 milliohms, it may not transfer power efficiently. Try a different cable.
Why is the charging so slow?
OTG output current is limited, so charging might be slow—this is normal. For urgent charging, use regular charging instead.
Can reverse charging damage my phone?
Generally no. Reverse charging is designed for emergency use and stays within safe output levels. However, performance may be affected if your phone is also running power-hungry tasks (watching videos, gaming) while charging.
Tips for Safe and Effective Use
Use certified cables and adapters to avoid high resistance.
Avoid heavy tasks on your OPPO phone while it is supplying power.
Monitor temperature; if your phone becomes very hot, disconnect and rest.
