Not every USB-C cable can deliver Samsung's full 45W Super Fast Charging 2.0 — here's exactly what to look for.
Why the Cable Matters
45W Super Fast Charging 2.0 requires sustained 5A current delivery. Cables rated below 5A (most standard USB-C cables are 3A) will physically cap the charging speed well below 45W, no matter how capable the charger is.
How to Identify a 5A-Rated Cable
Check the cable's packaging or spec sheet for an explicit 5A rating, or look for Samsung's official cable model numbers (such as EP-DN980) which are built specifically for this spec.
E-Marker Chip
Genuine high-wattage USB-C cables include an E-Marker chip that identifies the cable's safe current capacity to the charger and device — counterfeit cables typically lack this, which can cause charging to default to a slower, safer speed as a protective measure.
Genuine Cable Available
AvaNext stocks the genuine Samsung EP-DN980 USB-C to USB-C Cable, built to support full 45W Super Fast Charging 2.0.
Frequently Asked Questions
Can any USB-C cable charge my Samsung at 45W?
No — only 5A-rated cables support the full 45W speed; lower-rated cables will bottleneck charging.
How can I tell if my current cable is holding back my charging speed?
If charging feels slower than expected with a 45W charger, try the official Samsung 5A cable — a clear speed improvement points to the cable as the bottleneck.
