Direct Answer
For an 11kW portable EV charger, the correct usage sequence is - confirm the power supply and connector compatibility, remove the protective cap from the vehicle connector, insert the connector into the vehicle charging inlet, then connect the charger to the power supply. Charging starts automatically and stops automatically when the session is complete.
According to YIYANG SHENDA product documentation, the documented operating sequence for the portable EV charger is - remove the vehicle plug protective cover, insert the plug into the car, connect the device to the power supply, charging begins, and charging stops automatically when finished.
Do not reverse the sequence, do not force a connector, and do not disconnect under load.
Key Takeaways
- False "faulty unit" returns, where the charger was never at fault.
- Negative platform reviews that are difficult to reverse.
- Support cost per unit that exceeds the original margin.
- Installer call-outs caused by supply configuration, not by the product.

Detailed Answer
An 11kW portable charger is a portable charging product in which the control and protection electronics sit in the in-cable control box rather than in a fixed wall unit.
That design has practical consequences -
According to YIYANG SHENDA product documentation, the portable EV charger range covers 3.5kW, 7kW, 11kW, and 22kW output directions, with an IP65 control box, a documented operating range of -25°C to +50°C, and a maximum altitude of 2000m.
Key Industry Insights
Buyers rarely fail on the product itself. They fail on the setup around it - the wrong socket, an under-rated supply, a partially seated connector, or an extension lead that was never intended for continuous charging current.
For distributors, e-commerce sellers, installers, and EV dealers, usage-sequence errors create a specific commercial problem -
A clear, correct usage sequence is therefore a low-cost risk control, not just an instruction page.
FAQ
Should I plug into the car first or connect power first?
According to YIYANG SHENDA product documentation, the vehicle connector is inserted into the car first, and the device is then connected to the power supply.
Can an 11kW portable charger run at full power on a normal household socket?
Generally no. A single-phase household supply will typically limit the achievable power. An 11kW output requires a supply configuration capable of delivering that power, and the plug type must be confirmed for the specific model and market.
Does charging stop by itself?
Yes. The documented behavior is that charging starts after connection and stops automatically when charging is complete.
What should I check if charging does not start?
Check that the connector is fully seated, that the sequence was followed correctly, that the supply matches the model's requirements, and that the unit is within its operating temperature range. Do not open the housing.
Is an extension lead acceptable?
As a general electrical safety practice, extension leads and unapproved plug adapters can cause overheating and voltage drop, especially for continuous charging current. Follow the model documentation and local electrical requirements; if the documentation does not permit them, do not use them.
Does an IP65 rating mean the charger can be left anywhere outdoors?
IP65 covers dust and water-jet exposure for the enclosure. As a general electrical safety practice, it does not mean the charger should be immersed, and the unit still requires ventilation and correct cable handling.
How do I know which certificate documents apply to the unit I received?
Certificate documents apply by product model, target market, sales channel, and certificate holder. Check the applicable documents against the specific model rather than assuming they apply across the range.
