Every brand page on this site lists a warranty length in its spec table. What almost none of them answer on its own is the question that actually matters when a charger fails: does the number on the box mean what you’d assume, and what can quietly void it before you ever file a claim? Here’s the warranty length for every brand covered on this site, side by side, plus the two installation details that matter more than the number itself.
Warranty length by brand
| Brand / model | Standard warranty | Notes |
|---|---|---|
| Enphase IQ 40 / IQ 50 (ex-ClipperCreek) | 5 years | Longest residential coverage on this site; commercial CS-100 is 3 years |
| FLO X6 / X8 | 5 years | Budget X3 drops to 3 years |
| Autel AC Pro | 5 years | Elite Home and Lite tiers are 3 years |
| Tesla Wall Connector (Gen 3) | 4 years | 48 months from invoice date, per Tesla's own warranty documentation; 12 months for commercial use |
| ChargePoint Home Flex | 3 years | Standard across all six Home Flex amperage versions |
| Emporia Classic / Pro | 3 years | Same coverage on both tiers |
| Wallbox Pulsar Plus | 3 years | A year short of Tesla's Wall Connector |
| Grizzl-E (all models) | 3 years | Upgradable to 5 years for an added fee at purchase |
| Autel Elite Home / Lite | 3 years | AC Pro only steps up to 5 years |
| Schneider Charge | 3 years | Built-in SmartAmp load management included |
| Siemens VersiCharge AC Series | 3 years | Base VersiCharge VC30 (non-networked) is 2 years |
| Webasto TurboDX | 3 years | A year longer than the Go's standard coverage |
| Lectron (all models) | Standard, unspecified length | Thinner published warranty track record than established competitors |
| Leviton EV32W / EV40P / EV48W | 2 years | Shortest standard coverage on this site |

| Webasto Go | 2 years | Shorter than most rivals on this site |
Emporia Classic EV Charger
- A straightforward 3-year standard warranty with no upgrade tier to track, from a brand with a direct-to-consumer support line rather than a dealer-network claims process.
- ENERGY STAR certification and UL listing both matter for the warranty itself — most manufacturer terms exclude damage from using an uncertified unit outside its rated conditions.

What actually voids a warranty
The warranty length on a spec sheet assumes a correct installation. The two things that put it at risk have nothing to do with how long or hard you use the charger:
- Unlicensed or non-code-compliant installation. Manufacturer warranty terms generally require the install to follow National Electrical Code standards and local permitting — installers and electricians consistently flag unlicensed or DIY hardwired work as the install detail most likely to jeopardize coverage, since the manufacturer has no way to verify the wiring behind a wall was done correctly. See our EV charger installation cost guide for what a licensed electrician’s install typically runs, and our Qmerit installation network guide for how one major booking network vets installers.
- Skipping the permit. This isn’t just a manufacturer-warranty issue — it’s a homeowners insurance issue too. Our EV charger homeowners insurance guide covers how insurers can deny a related claim outright if a fire or failure is later traced to unpermitted wiring, on top of whatever the manufacturer’s own terms say.
Parts coverage isn’t the same as a free reinstall
Tesla’s own Wall Connector warranty documentation draws a distinction worth generalizing to any brand: a confirmed defect gets the unit replaced at no charge, but the owner is responsible for the reinstallation cost and any on-site inspection fee — unless the original install was done by a Tesla-recommended certified installer, whose own labor coverage then applies separately. Read any charger’s warranty terms for this same parts-vs-labor split before assuming “replacement” means a free reinstall. It rarely does unless you used a manufacturer-approved installer the first time.
The bottom line
Three years covers most of the mainstream market — ChargePoint, Emporia, Wallbox, Autel’s Elite and Lite tiers, and Schneider all land there. Enphase’s residential IQ line, FLO’s X6/X8, and Autel’s AC Pro are the real outliers at 5 years, and Tesla’s 4-year Wall Connector coverage beats the 3-year standard without being the single longest in the category. None of that matters if the install itself wasn’t licensed and permitted — that’s the detail that actually determines whether a warranty claim gets paid, regardless of whose name is on the box.
