7kW vs 22kW EV Chargers: Which One Do You Need?

If you're setting up home charging for an electric car in India, the first real decision isn't the brand — it's the power rating. HevenX sells two home EV chargers, a 7kW wall-mount unit and a 22kW portable round charger, and the right pick comes down to your home's electrical connection and how fast you actually need to charge.

What the numbers mean

An EV charger's kW rating is simply how much power it can deliver to your car per hour. A bigger number charges faster, but only if your car's onboard charger and your home's electrical supply can actually use that much power. Buying a charger rated higher than your connection supports doesn't get you faster charging — it just sits underused.

7kW: the everyday home charger

Our 7kW Wall Mount charger runs on a standard single-phase household connection — the kind most Indian homes already have, with no electrician-arranged phase upgrade needed. Plugged in overnight, it comfortably delivers a full charge for most electric cars sold in India today. For a typical daily commute, an overnight top-up on a 7kW charger is more than enough.

It's a fixed, wall-mounted install — a good fit if you park in the same covered spot every night and want a permanent, weatherproof setup.

22kW: for three-phase connections and faster turnarounds

The 22kW Portable Round charger needs a three-phase electrical connection, which isn't standard in every home. If you have one — or are willing to arrange the upgrade — this charger cuts charging time significantly and adds the flexibility of a portable, carry-anywhere design instead of a fixed wall unit. It suits larger-battery EVs, or households with more than one electric vehicle sharing a single charging point.
