EV charger specifications, compared against the category

A charger’s amperage is only half the decision. The other half is the circuit it needs — and almost no listing tells you that. This site computes both.

Most EV charger advice tells you which one is best. This site tells you what the market looks like, so you can see where any particular unit sits in it — and what installing it will actually ask of your panel. The median charger here outputs 40 A and needs a 50 A breaker.

Start with the finder

Five questions about your car, your panel and where the charger will go, and the EV charger finder narrows the catalogue to the ones that fit. Every result carries the breaker its output implies.

Browse by how it installs

Hardwired EV Chargers — A hardwired charger is wired straight to the panel with no plug in the path.
Plug-In EV Chargers — A plug-in charger hangs on the wall and plugs into an outlet, almost always a NEMA 14-50.
Portable EV Chargers — A portable charger lives in the car rather than on the wall, and usually runs from either a household socket or a dryer outlet.

Browse by output, connector or feature

The same catalogue cut the other ways people shop for it — by the amperage the panel can carry, by the plug the car takes, or by what the charger does beyond charging.

The number nobody puts on the box

An EV charger runs at full output for hours at a stretch, which makes it a continuous load. The branch circuit therefore has to be rated at least 125% of what the charger draws. A 40 A charger needs a 50 A breaker; a 48 A charger needs a 60 A; a 50 A charger needs a 70 A, because 62.5 is not a size anyone manufactures.

That single rule is the largest hidden cost in buying a home charger, and it is the reason two chargers eight amps apart on a listing can be hundreds of dollars apart once installed. Every result on this site carries the breaker its published output implies.

This is arithmetic, not a design. The breaker figures here are the manufacturer’s published output multiplied by 1.25 and rounded up to the next standard size, which is what the continuous-load rule requires. They tell you what to expect before you call an electrician; they are not a substitute for one, and they say nothing about whether your panel has the capacity, what wire the run needs, or what your local code requires.

What a baseline is, and why it is the whole point

A single average across every EV charger would be meaningless. This corpus runs from 10 A travel units to 80 A commercial-adjacent wall boxes, and someone shopping a garage charger is not served by a number spanning both. So baselines are computed per install method, per output class and per connector — each axis on its own, because 3 install types by five output classes is fifteen cells over 71 products and almost none of them would clear the floor.

That produces 10 baselines across 10 groups. Where a group holds fewer than 8 listings, no baseline is published at all.

What we do not do

We do not test chargers, and we say so on every page. There is no lab here, no load bank, no meter. What we have is the whole catalogue read consistently, which is a different kind of useful and an honest one.

We are also not electricians, and nothing here is electrical advice. The breaker figures are arithmetic on a published rating; the panel, the wire and the sign-off belong to someone licensed.

We do not publish star ratings or review counts, and we do not print exact prices. Where a listing does not state a specification, we print not stated rather than a plausible default.

How the corpus is cleaned

Search results for EV chargers are mostly not EV chargers. Adapters and extension cords outnumber the chargers, and they are the hard case, because an adapter publishes an amperage and a connector exactly as a charger does. Every one of them is excluded before a figure is published, and the methodology page documents exactly how, including where the rule fails.

About this site

EV Charger Data is written by a named editor working from published specifications, and funded by affiliate commission on Amazon purchases. Both of those facts are documented rather than buried:

How we compile these figures — the full method, including where it fails.
Affiliate disclosure — how this site earns, and what that does not influence.
Contact — corrections to published figures are the most useful thing you can send.
