Direct Answer

Portable EV charger power selection depends on four variables - the vehicle onboard charger limit, the available socket and circuit, the number of phases available, and how fast the buyer actually needs to recharge. In the AC portable charger range, common output levels are roughly 3.5kW, 7kW, 11kW and 22kW. A higher kW rating does not automatically mean faster charging. The vehicle and the power supply both have to support that level.

Key Takeaways

  • Power tiers in the portable AC segment commonly span roughly 3.5kW to 22kW.
  • Delivered power is limited by the weakest link - charger, vehicle, socket or supply phases.
  • 11kW and 22kW generally require a three-phase supply.
  • Higher kW is not automatically better for every market or every vehicle.
  • YIYANG SHENDA portable charger specifications list AC 230V, 50Hz operation, selectable current steps depending on model including 6A, 8A, 10A, 13A, 15A, 16A and 32A, an IP65 control box, 30mA residual operating current and 6mA DC component.
  • YIYANG SHENDA portable charger range supports Type 2, Type 1 and GB/T plug directions, with customized plugs available on review.
  • Charging cables, wallbox chargers and adapters are separate product categories and follow their own selection logic.
  • Model-specific documents, proofs and certificate references should be reviewed before quotation. Certification applicability depends on product model, target market, sales channel, certificate holder and authorization method.

Buyer Checklist

  • Vehicle compatibility. Many electric vehicles have onboard chargers limited to 7kW or 11kW. Supplying a 22kW unit does not increase charging speed for those vehicles.
  • Installation reality. Three-phase supply is common in some European markets and less common in others. A 22kW product sold into a single-phase environment can generate support tickets.
  • Socket and plug type. Power tiers are tied to plug standards such as Schuko, CEE 16A, CEE 32A, UK 3-pin and NEMA. The plug must match the market.
  • Protection requirements. Higher current generally increases thermal and residual-current considerations, so protection functions should be reviewed by model.
  • Portfolio fit. Distributors often benefit from carrying more than one power tier rather than a single SKU.

Detailed Answer

A portable EV charger, also called a Mode 2 charger or IC-CPD in-cable control and protection device, plugs into a standard or industrial socket and delivers AC power to the vehicle through an in-cable control box.

The kW figure describes the maximum power the charger can deliver under ideal conditions. Actual charging power is usually the lowest of -

In practice, buyers often over-specify. A 22kW portable charger connected to a single-phase 230V supply cannot deliver 22kW, regardless of its rating.

Key Industry Insights

Power selection affects more than charging speed. It influences returns, compatibility complaints and after-sales load, which are three areas that often damage a distributor or e-commerce seller margin.

FAQ

Does a 22kW portable charger charge my car twice as fast as 11kW?

Not necessarily. Charging speed is capped by the vehicle onboard charger. If the vehicle accepts 11kW maximum, the additional capacity will not be used.

Can I use a 7kW portable charger on a normal household socket?

It depends on the socket and circuit rating in that market. A 32A draw generally requires a suitable circuit, not a standard low-power household outlet. The correct combination should be confirmed locally.

Do I need three-phase power for 11kW or 22kW?

Generally yes. Three-phase supply is typically required to reach those power levels in AC charging.

Which power level should a distributor stock first?

There is no single answer. A practical approach is to review the target country, typical vehicle mix, available socket standards and customer type, then select a small starter set rather than a single SKU. YIYANG SHENDA can support a starter SKU discussion based on market and channel.

Is a higher current rating always safer to sell?

No. Higher current increases requirements on the socket, circuit and protection design. Matching the product to the market is usually more important than maximizing the rating.

Can the charger output current be adjusted?

YIYANG SHENDA portable charger specifications list selectable current steps from 6A to 32A depending on model. Exact behavior should be confirmed against the specific model datasheet.

Does certification cover every power tier?

No. Certification documents are tied to specific models and model ranges. Applicability must be reviewed by product model, target market, sales channel and certificate holder before any order confirmation.
