Bottom line: Pick the Tesla Universal Wall Connector if your garage is Tesla or NACS-first — it charges Teslas fastest and includes a J1772 adapter for everything else. Pick the ChargePoint Home Flex if you run J1772 EVs and want adjustable amperage plus built-in energy monitoring.

The verdict#
These two sit in the same 48–50A performance class, so daily charging speed is close for most J1772 vehicles. The real difference is the connector and the software. The Tesla Universal Wall Connector speaks NACS natively, which is the fastest path for a Tesla and comes with a J1772 adapter so other EVs still work. It also carries the category's longest warranty at four years, but it has no built-in energy monitoring.
The ChargePoint Home Flex is J1772-native and its headline feature is adjustable amperage from 16A to 50A, which lets you match a constrained electrical panel without buying a different charger. Its app ecosystem and energy monitoring are the most polished in the category, which matters if you want to track cost per session or manage charging on a time-of-use rate.
Which should you choose?#
- You drive a Tesla or another NACS vehicle and want native charging speed
- You want the longest warranty in the category (4 years)
- You have a mixed garage and can use the included J1772 adapter for a second EV
- Your household runs J1772 EVs (most non-Tesla brands)
- Your panel is tight and you need to dial output down from 50A
- You want detailed energy monitoring and the most established charging app

Common questions#
Yes. The Universal version includes a J1772 adapter, so it charges any J1772-compatible EV, though non-Tesla vehicles charge at standard J1772 speeds rather than the faster NACS-native rate.
Yes, using the J1772-to-Tesla adapter that ships with the vehicle. The Home Flex delivers up to 50A to a Tesla the same way it does to any J1772 EV.
