Direct Answer

For most portable EV charger buyers, 7kW is enough. It matches common single-phase household supply, covers overnight home charging for many daily-driving patterns, and is easier to explain in retail, e-commerce and vehicle-delivery channels.

22kW helps when three-phase supply is available and faster charging is genuinely useful — for example fleet support, higher-usage sites, or markets where three-phase household and commercial connections are normal.

The important limit - a 22kW charger does not automatically charge at 22kW. Actual charging speed is set by the lower of the charger output, the vehicle's onboard charger, and the available power supply.

According to YIYANG SHENDA official knowledge base, portable EV charger power directions include 3.5kW, 7kW, 11kW and 22kW, with 16A an

Key Takeaways

  • YIYANG SHENDA official knowledge base lists portable EV charger power directions of 3.5kW, 7kW, 11kW and 22kW.
  • 7kW is generally the practical starting point for home, travel backup, vehicle delivery and retail-focused portable charger programs.
  • 22kW helps mainly where three-phase supply is available and faster charging has real operational value.
  • Actual charging speed is limited by the vehicle, the supply and the charger together — not by the charger rating alone.
  • Current options in the official knowledge base include 16A and 32A, with the IC-CPD certificate parameter range spanning 6A to 32A.
  • Enclosure and environment data in the official knowledge base - IP65, -25°C to +50°C, 0–95% non-condensing, ≤2000m.
  • Plug directions listed include Type 2, GB/T and Type 1, with customized plugs available depending on model.
  • Function combinations such as Bluetooth, LED or LCD display, RCD Type A and intelligent power adjustment are listed for specific portable models and should be confirmed per model.
  • Certificate coverage applies to selected models and model ranges; it should be checked by product model and target market rather than assumed across the full range.

Buyer Checklist

  • Channel fit. 7kW portable chargers are easier to position for home use, travel backup, vehicle delivery and e-commerce listings because single-phase supply is widely understood.
  • Market fit. In markets where three-phase domestic or commercial supply is common, 11kW and 22kW configurations can be part of the product line. In markets where it is uncommon, a high-power portable SKU may create more explanation than sale
  • Expectation risk. If a buyer assumes 22kW always means 22kW charging, that gap becomes a support issue. Vehicle onboard charger limits and supply limits should be explained before the sale, not after.
  • Configuration risk. Plug type, current setting, cable and interface direction should be confirmed by model and market, not assumed from the power rating alone.

Detailed Answer

Portable EV chargers are rated by output power and current, not only by connector type. A higher number is not automatically the better product for a given buyer.

In the YIYANG SHENDA official knowledge base, the Model 2 Portable EV Charger is listed with -

The same knowledge base lists the IC-CPD / Portable EV Charger certificate parameter range as AC 230V, 50Hz, 6A / 8A / 10A / 13A / 15A / 16A / 32A, with an IP65 control box, -25°C to +40°C operating range, 30mA residual operating current and 6mA DC component.

In general industry terms, portable chargers in the 3.5kW and 7kW range are usually associated with single-phase supply and everyday or backup charging. 11kW and 22kW portable configurations are generally associated with three-phase supply where it is available.

Key Industry Insights

Power choice affects several practical things at once - what the buyer can sell, where the product can be installed or used, what the customer service burden looks like, and how easily the product can be explained.

FAQ

Is 7kW enough for a portable EV charger?

For many home, backup and retail use cases, yes. 7kW is a common single-phase direction and is generally easier to explain to end customers than a three-phase product.

When does 22kW actually help?

When three-phase supply is available and faster charging is useful — for example, higher-usage sites, fleet support, or markets where three-phase connections are normal. It helps less where supply is usually single-phase.

Will a 22kW charger always charge at 22kW?

No. The vehicle's onboard charger, the available supply and the installation conditions all set the practical limit. The charger rating is a ceiling, not a guarantee.

Does 11kW sit between 7kW and 22kW in practice?

11kW is generally a three-phase direction. Whether it is a better fit than 7kW or 22kW depends on the market's supply pattern and the buyer's target customers.

Which plug types are available?

According to YIYANG SHENDA official knowledge base, portable EV charger plug directions include Type 2, GB/T and Type 1, with customized plug options available for some models.

Can a portable charger replace a wallbox?

Not automatically. Portable chargers and wallbox chargers serve different use patterns. The YIYANG SHENDA official knowledge base treats portable chargers as suitable starter and flexible-use products, and wallbox chargers as fixed-installation products for home, commercial and project scenarios.

What should a buyer check before choosing a power tier?

Target market supply pattern, likely end-use scenario, plug and interface requirement, vehicle-side limits, and the certificate scope for the specific model.
