Pretty much every EV charger install we do in the Phoenix metro lands on one of two units: the Tesla Wall Connector or the ChargePoint Home Flex. Both are excellent. Both are wall mounted Level 2 chargers, both can deliver 48 amps when hardwired, both are well supported. The right one for your house depends on what you drive, who else in the household charges, and how much you care about app features.
Here is the honest comparison from an installer's perspective, not a manufacturer brochure.
That covers 90% of decisions. Read on if you want the why.
Both units are rated for 48 amps when hardwired on a 60-amp circuit. That gives you somewhere around 44 miles of range per hour for most EVs, which is more than enough to fully recharge any vehicle on the market overnight. If you only have a 50-amp circuit available, both can be configured down to 40 amps. The speed comparison ends in a wash.
This is the section that has changed the most in the last two years, so pay attention if you are reading older comparison articles.
Tesla Wall Connector comes with a NACS plug, the Tesla connector. For years that meant Tesla only. As of the current Gen 3 unit, Tesla sells a J1772 adapter that lets you charge non-Tesla EVs from the same wall unit. The catch: you have to swap adapters every time you charge a non-Tesla vehicle, and you have to keep track of the adapter.
ChargePoint Home Flex ships with a J1772 plug, which is the universal standard that every non-Tesla EV uses today. To charge a Tesla, you use the small NACS-to-J1772 adapter Tesla includes with every car. The adapter lives in the trunk, you grab it when you plug in.
The auto industry is moving to NACS over the next few years. Ford, GM, Rivian, Hyundai, Kia, and most other major brands have announced they will switch new vehicles to NACS connectors. For now though, J1772 is what most non-Tesla EVs on the road actually use. ChargePoint stays universal regardless of which way the transition shakes out.
Tesla Wall Connector: Connects to the Tesla app if you own a Tesla vehicle. Basic charging info, scheduling, firmware updates. If you do not own a Tesla, the app integration is essentially zero. The unit will still charge any J1772 vehicle (with the adapter), it just will not show up in any meaningful app.
ChargePoint Home Flex: Connects to the ChargePoint app regardless of which vehicle you drive. You get detailed kWh tracking, cost calculations based on your APS or SRP rate plan, scheduling, charging session history, and reminders. The app is the same one used at public ChargePoint stations, which is useful if you also charge away from home.
For Phoenix homeowners on APS time-of-use plans or SRP EV pricing plans, the ChargePoint scheduling and rate-aware features genuinely save money. The Tesla scheduling is fine, but the ChargePoint energy reporting is more thorough.
Pricing moves around but as of this writing:
The Tesla unit is the budget winner for the actual hardware. Installation cost is essentially the same either way, since the wire run, breaker, and labor do not change based on which charger you mount on the wall.
Both units are well built. The Tesla Wall Connector has a slightly more polished aesthetic, matte plastic with hidden cable management, and feels Apple-product clean. The ChargePoint Home Flex is a little more utilitarian but feels solid. Cable lengths run 18 to 24 feet on both, which is plenty for any standard Phoenix garage layout.
One small thing: the ChargePoint cable is a bit stiffer in extreme cold, which is irrelevant in Arizona. The Tesla cable handles Phoenix summer heat fine. Either one is built for our climate.
Whichever charger you pick, two things matter for a Phoenix install:
If you only own Teslas and plan to keep owning Teslas, get the Tesla Wall Connector. It is cheaper, looks great on the wall, and integrates cleanly with the car you already have.
If your household has any mix of brands (one Tesla and one Ford, for example, or you might trade in for a different brand in the next few years), get the ChargePoint Home Flex. The universal J1772 plug with the Tesla adapter is the more flexible setup, and the app is better for anyone not living inside the Tesla ecosystem.
You really cannot make a bad choice between these two. We install both regularly and both perform reliably for years when hardwired correctly.
We are a family owned Phoenix electrical contractor and we install Tesla Wall Connectors and ChargePoint Home Flex units across Mesa, Scottsdale, Gilbert, Chandler, Tempe, Queen Creek, Paradise Valley, and Fountain Hills. If you are not sure which one fits your house, or you want a real estimate on installation, contact us for an estimate. We will look at your panel, your garage, and your charging needs, and give you straight answers. For more on the install itself, see our EV charger installation page.
