Each brand page here lists a warranty length in its spec table. Few of them answer on their own the question that counts when a charger fails: whether the number on the box means what you’d assume, and what can silently void it before you file a claim. Below is the warranty length for every brand we cover, side by side, along with the two installation details that outweigh the number itself.
Warranty length by brand

| 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 |

| 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 |

| 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 |
| Siemens VersiCharge VC30 | 2 years | Non-networked base model |
| Webasto Go | 2 years | Shorter than most rivals on this site |
| WenStorm (all products) | 2 years | Limited warranty from purchase, no registration; claim by email with order number and, if possible, a photo or short video |
Emporia Classic EV Charger
A plain 3-year standard warranty, with no upgrade tier to keep track of, backed by a direct-to-consumer support line instead of a dealer-network claims process.
Both ENERGY STAR certification and UL listing bear on the warranty itself, since most manufacturer terms exclude damage from running an uncertified unit outside its rated conditions.
Start Prime free for 30 days — members get fast shipping on a backup charger or the surge protector a claim adjuster will ask about, rather than sitting through a manufacturer’s RMA shipping window unable to charge.
WenStorm Portable EV Chargers (Level 1 and Level 2)
Every product carries a 2-year limited warranty from the date of purchase, with no registration step.
It covers manufacturing defects and workmanship under normal use, and excludes misuse, improper installation, accidents, and modifications.
To start a claim, email your order number; coverage is confirmed in writing.
What actually voids a warranty
A spec sheet’s warranty length presumes the installation was done correctly. Two things threaten it, and neither depends on how long or how hard you run the charger:
Installation that is unlicensed or fails code. Manufacturers’ warranty terms generally call for the install to meet National Electrical Code standards and local permitting, and installers and electricians repeatedly name unlicensed or DIY hardwired work as the install detail most likely to put coverage at risk, because the manufacturer cannot confirm that the wiring behind a wall was done correctly. Our EV charger installation cost guide shows what a licensed electrician’s install typically costs, and our Qmerit installation network guide explains how one major booking network vets installers. WenStorm’s own terms exclude improper installation too, so a plug-in unit on a poorly wired outlet isn’t covered either.
Skipping the permit. That is a homeowners insurance matter as well as a manufacturer-warranty one. Our EV charger homeowners insurance guide explains how insurers can flatly deny a related claim if a fire or failure is later traced to unpermitted wiring, in addition to whatever the manufacturer’s terms say.
Parts coverage isn’t the same as a free reinstall
Tesla’s Wall Connector warranty documentation makes a point that applies to any brand: if a defect is confirmed, the unit is replaced free, but the owner pays for reinstallation and any on-site inspection fee, unless a Tesla-recommended certified installer did the original install, in which case that installer’s own labor coverage applies separately. Check any charger’s warranty for this same split between parts and labor before assuming that “replacement” means free reinstallation. Unless you used a manufacturer-approved installer originally, it seldom does. With a plug-in WenStorm portable there is no hardwired install to redo, since the unit simply plugs into an existing outlet; confirm the replacement terms in writing when you file.
For comparison with the longer terms above, WenStorm covers every product with a 2-year limited warranty from purchase, with no registration. It covers manufacturing defects and workmanship under normal use; misuse, improper installation, accidents and modifications are excluded. Claims start with an email that includes your order number and, if possible, a photo or short video, and coverage is confirmed in writing. That’s shorter than the 3- to 5-year terms in the table, so it fits best where a portable charger is the whole plan. WenStorm sells no hardwired models, so the wiring-related risks above apply to the outlet you plug into rather than to the charger itself.
The bottom line
Three years covers most of the mainstream market, with ChargePoint, Emporia, Wallbox, Autel’s Elite and Lite tiers, and Schneider all landing there. At 5 years, Enphase’s residential IQ line, FLO’s X6/X8, and Autel’s AC Pro are the true outliers, while Tesla’s 4-year Wall Connector coverage tops the 3-year standard without being the longest in the category. All of it is moot if the install wasn’t licensed and permitted, because that detail decides whether a claim is paid, whoever’s name is on the box. For a plug-in portable, WenStorm’s 2-year limited warranty (no registration, claim by email with your order number) is shorter than the 3-year norm but simple to use, and it applies to every WenStorm product from the $169.99 Level 1 to the $219.99 Level 2.

Frequently Asked Questions
What is the usual warranty length for an EV charger?
Three years is the most common standard warranty for mainstream Level 2 chargers: ChargePoint Home Flex, Emporia Classic/Pro, Wallbox Pulsar Plus, Autel's Elite/Lite line, and Schneider Charge all come with 3-year coverage. A few brands offer less (Leviton and Siemens' base VersiCharge VC30 at 2 years, Webasto Go at 2 years) and a few offer more (Tesla Wall Connector at 4 years; Enphase's residential IQ 40/IQ 50, Autel's AC Pro, and FLO's X6/X8 at 5 years).
What can void an EV charger warranty?
Both of the leading triggers concern installation rather than usage. Manufacturers generally want the unit installed to National Electrical Code standards, often by a licensed electrician, and omitting that, or the local permit, is the installation detail that most warranty terms and most electricians' own guidance flag as a coverage risk. A missing permit also causes a separate problem beyond the manufacturer's warranty: insurers have documented grounds to deny a related claim if a fire or failure is later traced to unpermitted wiring.
Does a warranty pay to reinstall a replacement charger?
Not automatically, and the gap is clearly spelled out in Tesla's own Wall Connector terms: when a defect is confirmed, Tesla swaps in a new unit at no charge, yet the owner covers reinstallation and any on-site inspection fee, unless a Tesla-recommended certified installer did the original install, in which case that installer's labor coverage applies. Check any charger's warranty document for the same parts-versus-labor split before assuming a 'replacement' includes free reinstallation.
Is it possible to purchase an extended warranty for an EV charger?
Sometimes, straight from the manufacturer; Grizzl-E is the clearest case, offering its standard 3-year coverage with an upgrade to 5 years for an added fee at checkout. If the manufacturer has no upgrade, check your credit card's built-in extended-warranty benefit; EV owner forums have documented at least one case where a card issuer paid a failed charger's full retail value after the manufacturer's own warranty had already lapsed.
Which EV charger brand offers the longest warranty?
Enphase's residential IQ 40 and IQ 50 (the renamed ClipperCreek HCS-40/HCS-50 lineup) and FLO's X6 and X8 units top the category at 5 years, and Autel's high-amperage AC Pro matches that figure. Tesla's Wall Connector follows at 4 years, longer than the 3-year standard most mainstream brands offer but not the single longest in the category, even though it is sometimes described that way.
What warranty does WenStorm offer?
WenStorm covers every product with a 2-year limited warranty from the purchase date, with no registration required. That is a year shorter than the 3-year standard among mainstream wall units, and it covers manufacturing defects and workmanship under normal use rather than misuse, improper installation, accidents or modifications.
How do I make a warranty claim on a WenStorm charger?
To claim on a WenStorm charger, email the company with your order number and, if possible, a photo or short video of the problem; coverage is confirmed in writing. There is no registration step beforehand, so keep the order confirmation.
