Question 1

What size breaker does my EV charger need?

Accepted Answer

At least 125% of the charger's output, because an EV charger is treated as a continuous load. A 40 A charger needs a 50 A breaker, a 48 A charger needs a 60 A, and a 32 A charger needs a 40 A. The wire has to match the breaker, not the charger. Every result on this site shows the breaker its published amperage implies — that figure is arithmetic, not a manufacturer specification, and your electrician signs off the actual install.

Question 2

How many amps do I actually need?

Accepted Answer

Fewer than most buyers assume. A 40 A charger adds roughly 30 miles of range per hour, so an overnight charge covers far more than a typical day's driving. The case for 48 A and above is a long commute, a large battery you regularly run low, or a household sharing one charger. The case against is the install: a 60 A circuit needs heavier wire and more panel capacity than a 50 A one, and that cost does not appear on the charger's listing.

Question 3

Hardwired or plug-in?

Accepted Answer

Above 48 A the choice is made for you — those chargers are hardwired. Below it, a plug-in unit on a NEMA 14-50 outlet can be unplugged and taken with you, and an outlet is useful for other things. Hardwiring is tidier, avoids a plug and receptacle as points of failure, and is generally required outdoors in wet locations. Note that a NEMA 14-50 outlet on a new circuit needs GFCI protection under current code, which adds cost either way.

Question 4

Is J1772 or NACS the right connector?

Accepted Answer

J1772 is the standard on almost every non-Tesla EV sold in North America; NACS is Tesla's connector and is being adopted more widely. In practice the connector rarely decides the purchase, because adapters in both directions are inexpensive and widely available. Buy for the amperage, the install method and the cable length, and treat the connector as the last filter rather than the first.

Question 5

How long should the cable be?

Accepted Answer

Longer than the distance you measure, and this is the specification owners most often say they would change. Twenty-five feet is the common length and it is not generous once the cable routes around the car rather than straight to it: the charge port may be on the far side, the car may be parked nose-out one day and nose-in the next, and a second vehicle may need reaching. Measure from where the charger will actually be mounted to the furthest port position you expect to use.

Question 6

Why do some results say 'not stated'?

Accepted Answer

Because the manufacturer did not publish that specification. This site prints 'not stated' rather than filling the gap with a plausible default, and those products still appear in your results — an incomplete listing is not a worse charger, only a less completely described one. A filter here excludes a product only when its listing positively contradicts what you asked for.

Question 7

Do you test these chargers?

Accepted Answer

No. Every figure is taken from the manufacturer's published listing and normalised into comparable units, then measured against the median for its own install type and amperage class. There is no lab, no load bank and no meter. Nothing here is electrical advice: the circuit and the install are for a licensed electrician, and the breaker figures we publish are arithmetic on a published rating rather than a design.
