7kW vs 11kW vs 22kW EV Charger

EV charger distributors often ask for 7kW, 11kW, and 22kW units as if those numbers are a simple price ladder. They are really a channel ladder. 7kW fits entry residential charging and single-phase markets. 11kW is a strong EU three-phase home charger. 22kW becomes the flagship wallbox for distributors and a better fit for light commercial positioning when the site can support it. A portable 16A charger fills a different role: travel, backup, and accessory sales.

Spire ESS EV charging products are built around EU wallbox and portable formats. This comparison explains how to choose the first assortment, what to confirm before an OEM or distribution quote, and how to connect chargers to a broader solar-storage catalog instead of treating them as standalone electrical accessories.

7kW: entry home charging and single-phase markets

A 7kW wallbox is the easiest product to explain for many home buyers. It suits overnight charging, driveway use, and markets where single-phase residential supply dominates. For a distributor, 7kW is often the entry SKU that creates volume and keeps price accessible. The RFQ should still clarify cable length, connector type, enclosure rating, app feature, and packaging, because home installers and retail buyers judge the whole experience, not only the power number. If the buyer also sells residential solar or storage, the 7kW charger can sit beside a home battery package as a simple energy upgrade.

11kW: the balanced EU three-phase option

An 11kW wallbox is a practical middle SKU for EU residential and light commercial channels with three-phase supply. It is faster than 7kW without pushing the site requirements as hard as 22kW. Installers like it because it can be positioned as a stronger home charging upgrade, and distributors like it because it creates a step-up offer without making the product line too narrow. Confirm the destination market's three-phase norms, connector format, cable or socket preference, app requirement, and certificate scope before ordering.

22kW: flagship SKU, not always the default

A 22kW charger is attractive because buyers often associate it with higher performance. In practice it only makes sense when the installation has enough electrical capacity and the vehicle or use case can take advantage of it. For distributors, 22kW is still important because it anchors the premium tier and helps with commercial or semi-public positioning. The risk is overselling it into homes where the site cannot support the load. A serious quote should include site type, expected installation environment, cable and connector details, enclosure requirement, and target documentation.

• Use 22kW as the premium wallbox and light commercial SKU.
• Confirm the site electrical capacity and installation environment before promising fit.
• Pair with solar and storage pages for buyers building a full energy catalog.
• Keep 7kW and 11kW in the assortment to avoid a one-dimensional product line.

Where the 16A portable charger fits

Portable EV chargers are not a replacement for wallbox distribution. They serve a different buyer: travel, emergency, second-home, dealership accessory, and low-commitment retail. The quote conversation should focus on plug standard, current setting, cable protection, instruction language, and packaging. For marketplace sellers, the portable SKU can test demand before committing to wallbox inventory. For solar-storage distributors, it is a useful add-on that keeps the EV category visible even when the customer is not ready for wallbox installation.

OEM and packaging choices

EV charger OEM work is more sensitive than simple logo placement because the buyer must preserve certification scope and installation clarity. Keep the electrical product standard unless sales confirms a change. Start with logo, manual language, carton, label, SKU code, and accessory kit. If the buyer needs app branding, cable length changes, or color changes, treat them as separate feasibility items. The RFQ should state target country, volume tier, packaging format, warranty expectation, and whether the charger will be sold alone or bundled with solar and storage.

Build the distributor assortment

A first EU assortment can be simple: 7kW for entry home use, 11kW for balanced three-phase home charging, 22kW as the premium wallbox, and a 16A portable charger as the accessory SKU. The mix depends on the buyer's country and channel. Installer-focused buyers may carry more 11kW and 22kW. Marketplace sellers may test portable and 7kW first. Solar distributors should include at least one wallbox that pairs naturally with home battery and PV packages.
