Quick answer: The JuiceBox 40 earned its reputation as one of the smartest 40 A home chargers ever sold — but Enel X Way exited the North American residential charging market in 2024, putting long-term app and support expectations in question. Existing owners should keep firmware current and document their warranty paperwork. New buyers in 2026 should generally choose an actively supported alternative unless they find deep clearance pricing.
For years, the JuiceBox 40 topped every "best smart EV charger" list. Then its parent company pivoted. This review covers what made it great, exactly what changed, what it means if you already own one — and which chargers we now recommend instead.
| Spec | Value |
|---|---|
| Max current | 40 A (hardwire or NEMA 14-50 plug variant) |
| Power delivery | ~9.6 kW |
| Connector | J1772, ~25 ft cable |
| Smart features | Wi-Fi, app scheduling, energy metering, voice assistants |
| Standout hardware | Dynamic load balancing (with optional JuiceNet Home sensor) |
| Certifications | UL listed · ENERGY STAR · outdoor-rated (-30°C to 50°C) |
In 2024, Enel X Way announced it was winding down its North American residential charging business, discontinuing new JuiceBox sales and restructuring support operations. Reported details worth knowing:
Support terms have continued to evolve since the announcement — verify the current app-service status directly before relying on smart functions or buying used.
The good news: as a UL-listed, J1772 hardwired/plug-in unit, the physical charger remains fundamentally sound hardware. Worst realistic case is losing app conveniences — not losing charging.
The hardware is genuinely well-built and charges any J1772 car at 40 A reliably even offline. The risk isn't charging — it's the shrinking smart-feature lifespan.
No. Basic charging works without the cloud. App features (remote control, detailed metering) are what depend on continued server support.
Mainly leftover/clearance or second-hand listings. At a steep discount it can still be rational — if you accept the support uncertainty and verify UL labeling on used units.
