Description
Ldnio SC3319 65W Fast Charging Desktop Charging Station
The SC3319 is a compact cube desktop hub that combines 3 AC outlets, 2 USB-C ports, and 1 USB-A port with up to 2500W mains capacity and 65W USB output. Gallium-nitride (GaN) circuitry delivers high wattage in a small footprint for laptops, tablets, phones, and wearables from one platform.
Port power sharing
- Two USB-C Power Delivery ports share the 65 W budget—for example 45 W + 20 W when both are in use, or up to 65 W on a single USB-C for demanding notebooks.
- Two USB-A Quick Charge slots deliver 18 W each for legacy phones or power banks.
- Smart-IC negotiation monitors each device’s draw about every 0.1 second when ports are loaded.
- Protocols include PD3.0, QC4+, and PPS.
Safety & materials
- Nine-point MultiProtect against over-current, over-voltage, short circuits, and thermal issues.
- Dual NTC thermistors feed temperature data for output throttling before overheating.
- V-0 flame-retardant ABS housing; internal fuses respond to surge spikes.
- LDNIO smart chip helps prevent overcharging, over-current, and short circuits.
Design & input
- Sandblasted aluminum top plate; front-facing USB ports.
- Soft-glow LED ring for power status; power button cuts all ports.
- Anti-slip silicone pad on the base.
- 1.5 m power cord; 100–240 V input range with EU plug.
Typical desk setups

Efficiency & packaging
GaN switching can reduce wasted heat compared with conventional silicon designs. Packaging uses recycled pulp trays with water-based ink printing. The product is engineered for an extended service life to limit charger turnover.
Quick setup
- Place the station with clearance for airflow.
- Connect a high-draw laptop to USB-C1 for up to 65 W solo or shared 45 W.
- Use USB-C2 for a second device; Smart-IC allocates power.
- Attach Quick Charge gear to USB-A ports.
- Use the power button to disable all outputs when not needed.
