Both charge-only USB-C cables and data blocker dongles can prevent USB data transfer while still allowing a connected device to charge. For everyday use, a charge-only cable is often simpler because the data-blocking protection is built into the cable and doesn't require a separate adapter.
How Do Charge-Only Cables and Data Blocker Dongles Compare?
| Feature | Charge-Only Cable | Data Blocker Dongle |
|---|---|---|
| Simplicity | One cable with data blocking built in | Requires a separate dongle and cable |
| Data Blocking | USB data lines are physically omitted | Depends on the design of the data blocker |
| Reliability | Fewer separate connection points | Adds another connection between the cable and device or charger |
| Charging Performance | Plugable charge-only USB-C cables support USB Power Delivery up to 240W | Charging capabilities vary depending on the dongle |
| Best Use Case | Regular charging, travel kits, classrooms, shared spaces, and managed deployments | Adding data blocking to an existing compatible cable when replacing the cable is not practical |
When Should I Use a Charge-Only Cable?
Charge-only cables are a good option for travel kits, classrooms, shared charging areas, and other environments where you don't need USB data transfer. Because the cable blocks data, you don't need an extra dongle to carry, lose, or accidentally leave behind.
Plugable offers three charge-only USB-C cable options:
-
USBC-CC1M: 1 meter (3.3 feet)

USBC-CC2M: 2 meters (6.6 feet)

USBC-CCS5X: 6-inch charge-only cables, pack of five

When Might a Data Blocker Dongle Make Sense?
A data blocker dongle can be useful if you already have data-capable USB cables that you need to continue using. It can provide a convenient way to add data blocking without replacing the existing cable.
For regular use, however, a dedicated charge-only cable reduces the number of separate components and helps ensure the cable cannot provide a normal USB data connection.
