Best USB-C Cables for the Anker 733 GaNPrime 65W
The Anker 733 is only as fast as the cable connecting it to your device. Using an underpowered cable dramatically reduces charging speed — sometimes to as low as 5W for a 65W-capable charger.

Why Cable Quality Matters for GaN Chargers
High-wattage USB-C charging (27W, 45W, 65W) requires cables rated for the corresponding power level:
| Cable Rating | Max Safe Wattage | Wire Gauge |
|---|---|---|
| USB 2.0 (old cables) | 5W (1A@5V) | Thin |
| USB-C 3A rated | 60W (3A@20V) | Medium |
| USB-C 5A (E-Marked) | 100W+ (5A@20V) | Thick |
| USB4 / Thunderbolt | 240W | Thick + E-Marker chip |
For the Anker 733’s 65W output, you need a USB-C 3A rated cable minimum — ideally with an E-Marker chip for guaranteed compatibility and safe power negotiation above 60W.
Recommended Cable Specs for the Anker 733
| Use Case | Minimum Spec | Recommended |
|---|---|---|
| Charging iPhone/AirPods | USB-C 3A, 1m | Any certified 3A cable |
| Charging Android phones | USB-C 3A, 1–2m | Braided 3A cable |
| Charging MacBook Air | USB-C 5A E-Marked | 100W+ rated cable |
| Charging MacBook Pro | USB-C 5A E-Marked | 140W+ rated cable |
Cable Length Recommendations
| Scenario | Recommended Length |
|---|---|
| Desktop / desk use | 1m (3.3ft) — minimal resistance |
| Couch / bed casual | 2m (6.6ft) |
| Travel / bag use | 0.5–1m (1.6–3.3ft) — compact |
| Laptop under desk | 1.5m (5ft) |
Cable length affects charging speed: Longer cables have more resistance, which reduces effective wattage at the device end. For 65W+ charging, keep cables at 2m or under.
What to Avoid
| Cable Type | Problem |
|---|---|
| Old USB-A to USB-C | Maximum 18W; doesn’t support USB-PD |
| Non-certified “60W” cheap cables | May limit at 5W due to missing E-marker |
| Cables over 3m | Resistance causes meaningful speed loss at 65W |
| Cables without E-marker (for 65W+) | Will cap at 60W, not 65W |
One Cable Tip: The Anker 733 Includes a Cable
The Anker 733 ships with a USB-C to USB-C cable rated for 60W in the box — sufficient for charging phones and tablets at full speed. For laptop charging at full 65W, an E-marked cable provides the last 5W increment, though many users won’t notice the difference.
