As an EV charger installer, I always purchase and advise clients who buy their chargers to only purchase EV chargers and any other electrical equipment part of EV Charging installation, such as circuit breakers, receptacles, wires, and even EV charging cables, to have a warranty and approved by an accredited certification body.
Having installed hundreds of EV Chargers, I have had my fair share of encounters with different EV charger brands, and I can tell you not all of them are the same in terms of their warranty and customer service.
Best EV Charger Warranty
After comparing multiple EV chargers, I highly recommend the Enphase Level 2 EV Charger for its five-year extensive warranty coverage, robust customer care service, high-quality construction, and smart charging capabilities.
However, potential users should be mindful of the limitations and usage conditions outlined in the warranty to maximize its benefits.
Enphase Level 2 EV Charger, Formerly ClipperCreek
- INSTALL WITH CONFIDENCE: Formerly ClipperCreek, the core technology that comes inside every Enphase EV charger has earned its award-winning reputation by delivering industry-leading durability and reliability. Now they're made even better with a 5-year limited manufacturer warranty and 24/7 customer support. This HCS-40 hardwired home electric car charging station comes fully assembled and offers quick installation to a dedicated 40 Amp circuit with any licensed electrician.
I have also discovered it is essential to make sure you know not only the warranty of the EV charger but also the quality of the EV charger because the quality will likely affect the likelihood of an EV charger requiring repair or replacement due to manufacturer defects, for these reasons, before purchasing an EV charger or recommending an EV charger to a client, I also check if an accredited certification body approves the EV charger.
I always check for product descriptions for certification marks since accredited bodies evaluate and certify products to safety standards to provide EV owners with confidence in knowing the EV charger is safe; since most electrical hazards can emanate from manufacturing defects, this will reduce the chances of EV charger repairs, and replacements – which also reduces your chances of engaging in long warranty battles and customer care services.
Warranty and Customer Services Needs by Levels
Homeowners install two common types of chargers, Level 1 EV chargers, and Level 2 EV chargers; according to my experience, different charging levels will require different approaches to warranty and customer service requirements.
80% of EV chargers that require replacements and customer services are Level 2 chargers because Level 2 chargers have more internal parts than Level 1 chargers, which increases their risk of complications. Level 1 chargers account for 20% of EV chargers that require repair or replacements since they are less complex where parts are concerned.
In this report, we have not included DC or Level 3 chargers because these chargers require extended repair and customer service support because they are found in public and commercial spaces and require a more extended warranty and customer support services based on usage and increased costs.
Comparing EV Charger Warranty and Customer Support
Warranties for EV chargers come in various lengths and options; we always recommend paying attention to which of these options are available; for example, it’s essential to check if the EV charger manufacturer will be responsible for manufacturing defects, wear and tear, and the response time for customer support.
We will compare Warranty and Customer Support from the list of EV home chargers we recommend and have experience with in terms of purchase, installation, and usage: the competitors.

Enphase Level 2 EV Charger Warranty
Enphase Level 2 EV Charger comes with a 5-year limited warranty, one of the most extended warranties we have been offered when purchasing EV chargers.
Enphase Energy’s I.Q. EV Chargers offers a comprehensive and user-friendly solution focusing on intelligent EV charging, which means the charger has many parts and components compared to other EV chargers in the market.
Enphase Level 2 EV Charger
The reason we appreciate the lengthy warranty period that Enphase offers is that innovative EV charging features are powered by hardware and software that are prone to manufacturing defects, wear and tear, software glitches, and compatibility issues.
The Enphase EV charger’s five-year warranty is essential to an intelligent charger because users might experience software glitches over time as software updates fail, software glitches and network connectivity issues; five years is enough for thorough tests and proactive monitoring to ensure your EV charger is in top-notch conditions.
Although the Enphase Level 2 EV Charger has many parts for intelligent EV charging capabilities, such as innovative energy management components and a rigid body structure with a sealed enclosure for all-weather use, they are well built.
The EV charger is tested three times before leaving the factory, and third-party testing and certification have been conducted by ETL in a Nationally Recognized Testing Laboratory (NRTL), giving you confidence in the quality, which means the likelihood of running into issues that require warranties is minimal.
The installation and use of the Enphase Level 2 EV Charger are quick and easy due to the conveniently built structure that makes it easy to install the EV charger; however, if you have problems, Enphase has a robust 24/7 online reputation for customer service.
The limited warranty on the Enphase Level 2 EV Charger doesn’t cover defects or parts requiring replacement due to wear and tear, for example, if the plug connectors of the plugs are loose due to frequent use; however, if the Enphase Level 2 EV Charger has manufacturer defects causing poor contacts of the connectors, the warranty offers options for repair or replacement instead of a payout.
Grizzl-E Smart Level 2 Charger Warranty
The Grizzl-E Smart Level 2 Charger is our #2 recommended EV charger based on its flexible three-year or five-year warranty coverage.
Grizzl-E Smart Level 2 Charger
While certain limitations and responsibilities exist, customers can benefit from the options provided and the manufacturer’s assurance of product quality being Energy Star and UL/cUL certified.
One of the features of the Grizzl-E Smart Level 2 Charger features that is prone to problems is related to software and communication problems; when we purchased the EV charger, it came out of the box pre-configured with OCPP software from a third-party dealer ChargeLab, we experienced compatibility issues during upgrade of the firmware which caused charging interruptions and inaccurate reporting of data.
We purchased another Grizzl-E Smart Level 2 Charger this year, and we are glad the company now has its software, the Glizzl-E Connect App, to solve this problem. However, being a new software released in OCT 2023, the three years of Grizzl-E software is enough for thorough testing and proactive software monitoring and communication.
Over the next few years, we expect software updates from the Grizzl-E Connect App to fix bugs, release new features and overall performance improvement, software and communication problems being one of the issues that can interrupt your EV charging or provide inaccurate reporting of charging data the three years warranty from Grizzl-E offers its buyers the confidence in the manufacturing and development processes.
For users who would like an extended warranty to hedge themselves against the issues emanating from Grizzl-E’s new software problems, Grizzl-E offers a flexible warranty option of 3 or five years.
Autel MaxiCharger Home EV Charger Warranty
Autel offers a three-year warranty on its Autel MaxiCharger Home EV Charger.
Autel MaxiCharger Home EV Charger is one of the best EV chargers when it comes to its specifications; being a Level 2 charger, it comes with more parts that can be faulty; however, to ease our minds, Autel MaxiCharger Home EV Charger has gone the extra length to comply with safety certifications and standards.
Some of the certifications and standards include UL 2231-1, UL 2231-2, UL2594, NEC Article 625, CSA C22.2, UL 916 safety compliance; FCC 15 Class B EMC compliance; Energy Star, OpenADR 2.0b certification; and top it all a 3-year warranty.
Autel MaxiCharger Home EV Charger
One of the differentiating features of the Autel MaxiCharger Home EV Charger is the integration of accessories and Add-ons such as the Autel RFID cards that enhance the EV charger functions; the Autel RFID cards use can be interrupted by network connectivity issues, which can affect user authentication, payment processing, and monitoring.
A warranty in check is a hedge against connectivity issues, and three years is enough time to test and inspect any network connectivity issues between the EV charger and its additional accessories.
Autel understands that three years is enough time to check for manufacturing defects, software issues, and communication issues that can prevent its EV charger users from initiating a charging session or hinder the collection of crucial charging data.
JuiceBox 40 Smart EV Charging Station Warranty
JuiceBox 40 Smart EV Charging Station is an EV Charger manufactured by Enel X and offers a three-year manufacturer’s warranty.
Enel X provides a manufacturer’s warranty for residential and commercial charging stations in the United States and Canada. Residential warranties cover defects for three years under normal conditions, while commercial warranties last up to three years.
The warranty excludes mishandling, improper installation, and extreme weather damage. Enel X covers shipping costs for residential customers within the United States. During the warranty period, the company will repair or replace defective units.
JuiceBox 40 Smart EV Charging Station
Residential units, including JuiceBox models, provide a three-year warranty under normal usage conditions.
EV owners purchase the JuiceBox 40 Smart EV Charging Station because of its innovative features, capabilities, and integration with third-party accessories providers such as Alexa. Users also choose the EV charger due to its 25-foot EV charging cable, and these key features are why you will need its three-year warranty.
Software Glitches, communication issues, and network connectivity issues are some of the problems that can affect the innovative EV charging features that users go for when they purchase the JuiceBox 40 Smart EV charging station, especially when they need to integrate the EV charger with third party accessories such as Alexa.
Three years of warranty coverage gives JuiceBox 40 Smart EV Charging Station users enough time to test and monitor the EV charger software and communication problems, especially when there are regular software updates by both the EV charger JuicePass mobile app and Alexa that can cause glitches interrupting your EV charging sessions and giving inaccurate reporting of charging data.
Another issue that users need the warranty for is the extended 25 feet that can experience physical damage that can affect the JuiceBox 40 Smart EV charging station functionality and pose safety hazards; we recommend inspecting these key features and any physical damage to ensure safety and reliability of the EV charger after purchase.
Wallbox Pulsar Plus Level 2 Smart Charger Warranty
Wallbox USA Inc. provides a three-year limited warranty for its intelligent charging hardware device and accessories. Pros include a reasonable warranty length, comprehensive coverage for components, and options for repair, replacement, or refund.
The warranty covers shipment costs for repaired or replacement equipment. However, cons include the lack of clarity on uninstallation and installation coverage, the absence of a payout option, non-coverage of labor costs (except shipment), uncertainty regarding wear and tear, non-transferability, a broad disclaimer of warranties, and limitations on liability for damages.
Users should consider these factors when assessing the overall value of the warranty.
Wallbox Pulsar Plus Level 2 Smart Charger
The flexibility to repair, replace, or refund provides options for users facing issues. Comprehensive coverage for essential components is a notable advantage.
Some of the features of the Wallbox Pulsar Plus Level 2 Smart Charger that buyers purchase the EV charger for are onboard intelligence for smart EV functions and compact design, and these are the key features why you will need a three-year warranty for the EV charger.
The compact design of the Wallbox Pulsar Plus Level 2 Smart Charger is due to the densely packed internal components that generate high heat density, resulting in poor thermal management.
Wallbox Pulsar Plus Level 2 Smart Chargers can be susceptible to heat-induced physical damage, affecting the EV charger functionality and posing safety hazards.
Wallbox Pulsar Plus Level 2 Smart Charger guarantees the EV charger is free from defects and workmanship under normal use. However, the three-year warranty is recommended for users who want a compact EV charger.
Another feature that is susceptible to issues is the onboard intelligence functions; since the intelligent features of the EV charger occur in the charger itself rather than the cloud, this means regular software updates and real-time software monitoring can be an issue, the Wallbox Pulsar Plus Level 2 Smart Charger covers the intelligence charging hardware parts ensuring coverage for essential components.
To top it all off, Wallbox offers flexibility by providing the option to repair, replace, or refund defective equipment in case of software or hardware issues at their sole discretion.
ChargePoint Level 2 Charger Warranty
ChargePoint’s Level 2 Charger offers a reliable three-year warranty, covering defects in materials or workmanship. While the warranty is non-transferrable, it includes comprehensive coverage for essential components. Users must handle installation and uninstallation, with on-site labor costs excluded.
ChargePoint Level 2 Charger
Its components are well-covered, but users should note non-transferrable terms and excluded labor costs. With a strong presence and reliable service, it’s a suitable choice for residential electric vehicle charging, offering peace of mind and support.
One of the most loved EV chargers is the ChargePoint Level 2 Charger; having installed countless of them, I have had my fair share of problems with the charger, mainly related to hardware, software, and communication issues. I have had power supply issues, but a few of them.
I believe the three-year warranty offered by ChargePoint Level 2 Charger Warranty is enough to ensure your charger is working perfectly; some of the key features covered by the warranty include hardware and software issues if a certified electrician installs the charger.
Some critical hardware problems you should check include broken clips, which will result in the charger not working; the main issues of the ChargePoint Level 2 Charger are related to software issues; some of the problems include innovative features not working and software update errors, we also suggest contacting customer care if the charger reports charging errors or current drops as this might be related to power supply issues.
Although these errors are rare, three years of ChargePoint Level 2 Charger Warranty is enough to hedge you against the issues mentioned that might be related to manufacturing defects.
Siemens US2 VersiCharge Universal Charger Warranty
The Siemens VersiCharge™ AC Series three-year limited warranty is commendable for its reasonable duration, comprehensive coverage, and flexibility through registration.
We recommend the Siemens US2 VersiCharge Universal Charger to clients with older homes that need an EV charger with power output adjustment capabilities; this EV charger offers increments range of 7.2 kW down to 1.8 kW; the EV charger should not be another issue on top of your old electrical system as the EV charger complies with safety and operational standards (cUL, SAE J1772, NEC® 625, FCC Part 15 Class B)
Siemens US2 VersiCharge Universal Charger
One of the critical features of the Siemens US2 VersiCharge Universal Charger is its innovative charging capabilities that allow delayed charging (scheduled charging) for up to 8 hours; for the innovative features to work, there must be a seamless integration of the hardware and software.
We have had issues with the Siemens US2 VersiCharge Universal Charger ourselves, all related to software glitches and hardware issues. We are all tied to innovative EV charging capabilities. Sometimes, the software will not connect to WIFI, or the charger will stop working or go to pause mode unexpectedly. However, in a rare situation, the three-year warranty is enough to get you to monitor and inspect software and hardware issues that might crop up after the EV charger’s purchase, affecting the EV charger’s functioning.
Lectron Level 1 EV Charger Warranty
Lectron’s products are backed by a commendable two-year limited warranty, offering assurance against defects in materials and assembly. However, customers should know potential costs, as labor and transportation expenses are not explicitly covered. The warranty lacks details on uninstallation/installation services and its transferability.
Lectron Level 1 EV Charger
The Lectron Level 1 EV Charger is one of the first chargers we recommend when a client is looking for a Level 1 charger. It’s a simple EV charger with fewer internal components, and its main unique feature is short circuit protection.
We have had clients ring us for us to inspect overheating and, in the worst cases, melting of components due to the charger overheating; most cases are due to the short circuit protection not working as intended, causing excessive current flow into the elements that overheat and melt the components.
We have also had issues with the same short-circuit protector not working, causing the charger to stop or slow charging your EV.
We highly recommend inspecting the hardware of the Lectron Level 1 EV Charger after purchase, and in case of any overheating, stop charging and contact customer care or a certified electrician for inspection of the EV charger.
We recommend the Lectron Level 1 EV Charger because hardware issues are a rare case, and having a two-year warranty is enough to inspect and monitor the overheating and hardware issues that might crop up, affecting the functionality of the Lectron Level 1 EV Charger.
Webasto Go Dual Voltage Portable EV Charger Warranty
The Webasto Go Dual Voltage Portable EV charger offers a compact design, robust safety features, and an auto-restart function for uninterrupted charging.
However, its two-year warranty falls short of the industry’s three-year standard. Users must be cautious as the warranty becomes void if non-contracted electricians conduct repairs, non-original parts are used, or unauthorized unit conversions occur, emphasizing the importance of professional installation.
Webasto Go Dual Voltage Portable EV Charger
However, buyers should note the two-year warranty and adhere to proper installation guidelines to avoid warranty voidance. It’s a reliable choice for those seeking portability and safety in an EV charger.
Some features marketed by Webasto Go Dual Voltage Portable EV Charger are thermal detection, auto-restart and recovery, and ground detection against faults, and these are the reasons why most EV owners will consider purchasing the Webasto Go Dual Voltage Portable EV Charger.
Most of the features work well out of the box. However, we have had cases of the Webasto Go Dual Voltage Portable EV Charger overheating due to the closely packed internal parts to accommodate the compact design of the EV charger, which results in poor thermal management.
Webasto Go Dual Voltage Portable EV Charger comes with a two-year warranty, and we do believe this is enough time to inspect and monitor cases that might arise related to hardware and thermal management issues; it’s important to note that such cases are rare, but might happen due to manufacturing defects.
