Buy the Grizzl-E Ultimate if you want the toughest full-speed charger to hardwire to a wall and forget - a cast-aluminum, IP67 48-amp box with no app dependency. Buy the ChargePoint Home Flex if you want flexible, selectable amperage, a polished app, and a public-charging network in the same account. One is built like a tank; the other is built to be smart and connected.
These two answer opposite priorities. The Grizzl-E Ultimate leads our best 48-amp roundup on sheer durability; the ChargePoint is one of the most recognized smart chargers in North America. Here is how they compare. We compile published specs and do the math rather than bench-testing either.
Speed
Effectively a tie at the top. The Grizzl-E Ultimate is a dedicated 48-amp / 11.5 kW unit, adjustable from 16 to 48 amps; the ChargePoint is selectable up to 50 amps (typically run at 48). Both need a 60-amp circuit and hardwiring to hit full speed, and both drop to whatever your car accepts. There is no meaningful charging-speed gap - the difference is everything around the speed.
Build and weather
The Grizzl-E, decisively. Its cast-aluminum enclosure is rated IP67 and NEMA 4X - the most weather-resistant shell of any 48-amp pick we rank, built to shrug off an exposed wall or a hard winter, with UL certification and built-in GFCI. The ChargePoint is rated for outdoor use and perfectly sturdy, but the Grizzl-E is in another class for ruggedness. For a carport or exterior mount, the Ultimate is the tank.
Smart features
The ChargePoint, clearly. It brings a mature app, scheduling, energy tracking, selectable amperage, and - uniquely - access to ChargePoint's large public network from the same account. The Grizzl-E Ultimate is deliberately spare on software; it is a rugged charger, not a connected gadget. If smart features and network access are the point, this is not close.
Value
It depends what you value. The Grizzl-E spends its budget on a shell and a service life that will outlast several app redesigns; the ChargePoint spends it on flexibility, an app, and a network. Neither is overpriced - they buy different things. For a permanent outdoor install you will never touch again, the Grizzl-E is the durable-dollar winner; for a connected, adjustable home unit, the ChargePoint earns its price.
The verdict
Grizzl-E Ultimate for durability and a hardwired, weatherproof, forget-about-it install; ChargePoint Home Flex for flexibility, app polish and network access. Read the full Grizzl-E Ultimate and ChargePoint reviews, and confirm your circuit in the amperage guide first.
How to choose between them
Where will it live?
If the charger mounts outdoors or in a harsh environment, the Grizzl-E Ultimate's IP67 cast-aluminum shell is the safer, longer-lasting choice. If it lives in a sheltered garage, the ChargePoint's enclosure is plenty and its flexibility becomes the bigger factor.
Do you want an app and a network?
The ChargePoint bundles scheduling, energy data and public-network access into one account - real value if you use public charging or a time-of-use rate. The Grizzl-E gives you none of that on purpose; if you want a charger, not a connected device, that simplicity is a feature.
Both are hardwired 48-amp units - size the circuit right
To get full speed from either you need a 60-amp circuit and a hardwired install, plus a car that accepts 48 amps. If your car caps lower, both back down to match. A licensed electrician confirms your panel can carry the circuit - see 60-amp vs 50-amp circuit.
