Both options prevent data transfer while allowing power to flow, but charge-only cables are usually the better long-term solution.
Quick comparison
| Feature | Charge-only cable | Data blocker dongle |
|---|---|---|
| Simplicity | One piece, nothing extra to carry | Extra dongle to remember |
| Security | No data pins at all, cannot transfer data | Blocks data, but relies on existing cable |
| Reliability | Fewer failure points | Adds a weak link, may reduce reliability |
| Charging performance | Full power support with quality cables | Some dongles limit current or slow charging |
| Best use case | Everyday charging, travel kits, and classrooms | Short-term fix with mixed legacy cables |
When to choose each
-
Travel kits, classrooms, and shared spaces
Use charge-only cables to reduce mistakes and avoid extra parts.
We offer three charge-only solutions at varying lengths that are an excellent all-in-one option:USBC-CC1M (1m),USBC-CC2M (2m),USBC-CCS5X (6-inch) -
Mixed legacy cabling
Dongles can serve as a stopgap if you already have a variety of older cables, but plan to phase in charge-only cables over time. -
General recommendation
Charge-only cables are the optimal choice as they integrate security directly into the cable, making them simpler, safer, and more reliable than dongles.
