Ohme, Hypervolt or Zappi EV Charger?

An honest comparison of the home EV chargers Jack fits, Ohme, Hypervolt and Zappi, with the real pros and cons of each from a fitter's point of view.

Written by Jack Snelling, qualified electrician Plain English, no jargon Updated June 2026

There is no single “best” home EV charger, only the right one for your car, your tariff and how you want to use it. The three brands Jack fits, Ohme, Hypervolt and Zappi, are all solid 7kW units that do the core job well. The differences come down to smart-tariff integration, the app, the look, and whether you want clever solar features. Here is an honest run through each, from the point of view of someone who fits them.

What do these chargers have in common?

Before the differences, the things they share. All three are 7kW single-phase units, which add roughly 25 to 30 miles of range per hour, plenty to fully charge overnight. They all need to be installed by a qualified electrician, certified and notified, and they all work with off-peak EV tariffs to cut your charging cost dramatically versus standard rate. So whichever you pick, the fundamentals are covered. The brand mostly changes the experience around the charging, not whether your car charges.

Ohme

Ohme has become a favourite for tariff-led charging. Its big strength is deep integration with smart tariffs, so it can automatically charge when electricity is cheapest and greenest without you fiddling. If your priority is squeezing every penny out of an off-peak EV tariff, Ohme is consistently one of the best at it.

  • Pros: excellent smart-tariff integration, strong app, great for minimising cost automatically.
  • Cons: the design is more functional than premium, and it leans heavily on the app, which suits some people more than others.

Hypervolt

Hypervolt is the design-led option, a good-looking unit with an LED-lit fascia and a polished app. It handles solar integration and load management well, and it tends to appeal to people who want the charger to look the part on the front of the house as well as work properly.

  • Pros: premium look, capable app, solar and load-management features, made in the UK.
  • Cons: sits at the higher end on price, and the styling is a “want” rather than a “need.”

Zappi (myenergi)

Zappi is the one to look at if you have, or plan to have, solar panels. Its standout feature is the ability to charge your car using surplus solar energy that would otherwise be exported, so you run the car on your own generation. Even without solar it is a capable 7kW charger, but the solar features are where it earns its place.

  • Pros: best-in-class solar diversion, flexible charging modes, well established.
  • Cons: the solar features are wasted if you have no panels, and it is at the pricier end, so you pay for capability you may not use.

What about Tesla or Pod Point?

You will see other well-known names too, like the Tesla Wall Connector and Pod Point, and they are perfectly good chargers in their own right. Jack fits and recommends Hypervolt, Zappi and Ohme, because between them they cover the three things people actually want, cheap smart-tariff charging, a premium look, and proper solar diversion. If you have a specific reason to want a different make, just ask and he will give you a straight view.

So which should I actually choose?

Honestly, it comes down to three questions. If you have solar or are getting it, Zappi is the obvious starting point. If your priority is automatically charging as cheaply as possible on a smart tariff, Ohme is hard to beat. And if you want it to look smart on the wall with a capable app behind it, Hypervolt leads.

Jack fits all three and will give you a straight recommendation based on your car, your tariff and your house, not on whichever one carries the best margin. The install also includes the important bit nobody mentions in the brochures: checking your fuse board and supply can take the charger in the first place.

What does fitting cost, whichever brand I pick?

Snelling Electrical fits home EV chargers from £900 fully fitted, including the survey, installation and certification. The exact figure depends on the charger you choose and your property, which you can read about on the EV charger installation page.
