Yes, you can charge a device with a data-only USB cable. Data-only cables include the VBUS and GND wires needed to deliver power, alongside the D+ and D− data lines.
- Cable has all four wires (VBUS, GND, D+, D−)
- Charger or port outputs power on the VBUS line
- Device accepts power without requiring data enumeration
- Cable is physically damaged or has a broken VBUS wire
- Charger does not supply power on VBUS
- You need full data transfer at the same time (charging still works, but data tasks may fail)
Why a Data-Only Cable Still Delivers Power
Every standard USB cable — USB-A, USB-B, Micro-USB, or USB-C — carries at minimum four wires: VBUS (5 V power), GND (ground), D+, and D−. A cable marketed as “data-only” simply means the manufacturer has not removed or blocked the power wires. Power flows the moment you plug it into a charger, regardless of whether data lines are active.
The term “data-only” is sometimes misread as the opposite of a charge-only cable. A charge-only cable drops the D+/D− lines but keeps VBUS and GND. A data-only cable keeps all four wires. Both types can charge a device.
How Much Power Can It Deliver?
Power delivery depends on the charger and the USB standard, not on whether the cable carries data lines. USB-C cables that meet USB Power Delivery specs can carry up to 240 W. Older USB-A data cables typically top out at 5 V / 0.5 A (2.5 W) on a standard port, or up to 5 V / 1.8 A on a charging port. Check the charger’s rated output, not just the cable type, to know how fast your device will charge.

Common Setups at a Glance
| Setup | Works? | Need | Note |
|---|---|---|---|
| USB-A data cable + wall charger | Yes | Charger with VBUS output | Charges at standard rate |
| USB-C data cable + USB PD charger | Yes | PD-rated cable and charger | Up to 240 W possible |
| Data cable + PC USB port | Yes | Nothing extra | Slow charge, ~2.5 W typical |
| Damaged cable (broken VBUS) | No | Replacement cable | No power path |
What the USB Specification Says
According to the USB Implementers Forum cable assembly specification, all compliant USB cables must include the VBUS and GND conductors. A cable missing those wires is non-compliant, not merely “data-only.”
When You Might Still Have a Problem
- Some budget cables use thin VBUS wire that limits current and causes slow or interrupted charging.
- Devices that require USB enumeration before accepting power (rare, mostly industrial hardware) may not charge from a data-blocked port.
- If you are also trying to flash firmware or sync files, a data-only cable handles both tasks fine — but a charge-only cable will block data transfer.
If you are troubleshooting a USB-C connection that is not behaving as expected, the guide on why USB-C to HDMI is not working covers several wiring and compatibility issues that apply broadly to USB-C cables.
Bottom line: A data-only USB cable will charge your device without any issue, provided the cable is undamaged and your charger supplies power on the VBUS line. The presence of data wires does not block or reduce charging — it just means the cable is capable of more than a charge-only cable.
