Symptoms
- Device doesn't charge when connected through the adapter
- Device isn't recognized for data transfer
- Adapter feels loose or wiggly at either connection
- Works for one function (charging) but not another (data)
Likely causes
- CommonAdapter is data-only, not rated for charging currentMany cheap adapters are designed for data or peripherals, not for delivering meaningful charging power.
- CommonUnderlying USB-A port is a low-power portPorts on some hubs, older computers, or airplane seats often supply less current.
- PossibleLoose physical connection at either endA worn or slightly bent connector can cause intermittent contact.
- PossibleAdapter itself is defectiveManufacturing defects are common in low-cost adapters.
- Less commonCable or device incompatibility beyond the adapterThe issue may lie with the cable or device rather than the adapter.
What to do
- Check the adapter's packaging or listing for whether it explicitly supports charging, not just data.
- Try the adapter in a different USB-A port, ideally directly on a computer or a powered hub rather than a low-power port.
- Wiggle-test both connections to rule out a loose fit.
- Test the same setup with a different device to isolate whether the adapter or the device is the problem.
- Replace the adapter with one explicitly rated for charging if that's your main use case.
