Why Can’t RecDual Dongle Charge My Phone?¶
If your phone is not charging while connected to RecDual Dongle, this guide explains the common causes and solutions.
Understanding the Charging Mechanism¶
RecDual Dongle’s Type-C PWR port:
Supports USB PD (Power Delivery) protocol
Maximum power: 66W
Does NOT support QC (Quick Charge) protocol
For charging to work, your phone must support PD protocol, not just any fast charging.
Common Cause: Protocol Incompatibility¶
The Issue:
RecDual Dongle PWR port only supports PD protocol.
If your phone uses:
QC (Quick Charge) only → Will NOT charge
USB PD → Will charge
Both PD and QC → Will charge via PD
Affected Devices:
Some older or budget smartphones only support QC fast charging without PD support. These devices may not charge through RecDual Dongle.
Checking Your Device¶
PD-Compatible Devices (Will Charge):
iPhone 15 and newer (all Type-C models)
Samsung Galaxy S21 and newer
Google Pixel 6 and newer
Most recent flagship phones
Potentially Incompatible:
Older phones with QC-only charging
Some budget smartphones
Some regional phone variants
How to Check:
Look up your phone’s specifications
Search for “USB PD” or “Power Delivery” support
Check manufacturer’s charging specifications
Troubleshooting Steps¶
Step 1: Verify Power Adapter
Ensure your power adapter supports PD:
Use a USB-C PD adapter
Apple USB-C adapters support PD
Many laptop chargers support PD
Check adapter for “PD” marking
Step 2: Check Connections
Power adapter → Type-C PWR port
Phone → Type-C DP IN port
All cables securely connected
Step 3: Try a Different Adapter
Use a known PD-compatible adapter
Try 45W or 65W PD adapters
Apple or Samsung official chargers work well
Step 4: Verify Phone PD Support
If using a QC-only phone:
Charging through RecDual Dongle is not possible
Use alternative charging method
Alternative Solutions¶
If your phone doesn’t support PD:
Option 1: Charge Separately
Record without charging through RecDual Dongle
Charge phone with its original charger when not recording
Option 2: Use a PD-Compatible Device
Most modern phones support PD
Consider upgrading if frequent recording is needed
Option 3: Monitor Battery
Start recording with full battery
Take breaks to charge when needed
What Should Work¶
Correctly working setup:
Phone supports USB PD
PD adapter connected to Type-C PWR
Phone connected to Type-C DP IN
Charging indicator shows on phone
Expected behavior:
Phone charges while recording
Charging speed depends on phone’s maximum PD rate
Some heat during use is normal
