40 Amp J1772 / Tesla Portable EV Charger (Level 1 & Level 2)

The KingVlotix 40A portable EV charger is designed for drivers who want one device that works everywhere: at home, on the road, and across different EV brands. With built-in support for both Level 1 (120V) and Level 2 (240V) charging, it eliminates the need to carry multiple chargers.

Dual-Voltage Charging Without Guesswork

This charger automatically detects input voltage and adjusts output safely:

  • 240V / up to 40A (Level 2) – fast home or garage charging via NEMA 14-50
  • 120V / up to 13A (Level 1) – emergency or travel charging via standard outlet

The smart power system prevents overload while maintaining optimal charging speed for each circuit.

One Charger for J1772 and Tesla

Equipped with a SAE J1772 connector and an included J1772-to-Tesla (NACS) adapter, this charger supports:

  • All J1772 EVs (Ford, GM, Hyundai, Kia, Nissan, BMW, Audi, etc.)
  • All Tesla models (Model 3 / Y / S / X)

This makes it an excellent choice for mixed-EV households or future vehicle upgrades.

Adjustable Current & Scheduled Charging

Charging current can be manually adjusted from 6A to 40A, allowing you to match older wiring or maximize speed on stronger circuits. Scheduled charging enables off-peak use, helping reduce electricity costs and grid strain.

25FT Cold-Resistant Charging Cable

The 25-foot cable easily reaches vehicles with rear or side charge ports, even in tight garages. Rated to operate down to -22°F, it remains flexible and safe in winter conditions without requiring extension cords.

Comprehensive Safety Protection

Built-in protections include:

  • Over-voltage / under-voltage protection
  • Over-current & over-temperature protection
  • Leakage and short-circuit protection

These safeguards ensure consistent, reliable charging for both your vehicle and your home electrical system.

Who This Is Best For: EV owners who want a single portable charger that works with both Tesla and non-Tesla vehicles, supports Level 1 and Level 2 charging, and adapts safely to different power sources.
