If you found a charger you like and noticed it carries the ETL mark instead of UL, you are in good shape, because ETL is a Nationally Recognized Testing Laboratory mark under OSHA with the same legal standing as UL under the National Electrical Code. The chargers below were tested to the same UL 2594 standard by Intertek rather than Underwriters Laboratories. The lab is different; the standard and the rigor are not.
What makes this worth explaining is that ETL appears on some excellent chargers precisely because Intertek’s certification timeline is faster and less expensive than UL’s, which is why brands launching new products or European companies entering the U.S. market often arrive with ETL rather than UL. Since the finished product met the same test criteria, the certification outcome is equivalent, even though the brand name on the mark appears different.
Verification works the same way as UL: find the control number on the product label and search the Intertek Directory of Listed Products, where a genuine ETL listing returns the manufacturer, the product category, and the testing standard applied. Every product in our grid has been verified in that database before inclusion.

ETL Certified EV Chargers are charging stations that have been independently tested and certified by Intertek, a Nationally Recognized Testing Laboratory (NRTL) in the U.S. ETL originally stood for Edison Testing Laboratories and performs the same role as UL (Underwriters Laboratories).
Think of it as a seal of approval that confirms your charger meets strict safety standards established by North American safety codes.
When a product carries the ETL mark, it has been tested to the exact same safety standards, such as UL 2594 for EV supply equipment, as a UL-listed product.
The question buyers ask most often about ETL is whether it is really the same as UL, and the honest answer is yes, from a legal and technical standpoint, because Intertek tests EV chargers to UL 2594, the same document UL uses, and both organizations hold NRTL status under OSHA regulations. Because NRTL status is what gives a mark legal standing under NEC 110.3(B), ETL and UL satisfy the same code requirement.
The bi-national certification framework between U.S. and Canadian electrical standards means UL 2594 and CSA C22.2 No. 280 are harmonized documents, and Intertek is accredited to test to both, which is why a single ETL certification round can cover both U.S. and Canadian market requirements simultaneously. Because UL operates under the same accreditation structure, the testing depth and acceptance criteria are identical regardless of which organization’s name appears on the certificate.
Tesla has used ETL across multiple Wall Connector generations because Intertek’s certification turnaround time better aligns with Tesla’s product launch cycles. At the same time, Wallbox and several other European brands chose ETL because Intertek has deeper European testing infrastructure, making the U.S. certification process simpler for companies already working with Intertek in their home markets. Because neither of these reasons has anything to do with safety testing depth, the fact that a charger is ETL rather than UL tells you about the manufacturer’s supply chain choices rather than about the quality of the safety testing.
Most U.S. electrical inspectors accept ETL without question because they are trained to recognize any NRTL mark as satisfying the listing requirement under the code. However, a small number of inspectors have UL as their personal default and may initially ask about the mark. Because ETL is OSHA-recognized, manufacturers can provide documentation of NRTL status that satisfies any legitimate code challenge, and the ETL Products Certified database serves as the public verification source, as UL Product iQ does for UL marks.
When ETL certifies a charger, they run it through multiple safety tests. The first check focuses on electrical protection. Your charger needs to survive power surges and electrical shorts without sparking fires or harming your vehicle’s battery.
The second test examines grounding and insulation systems. Good grounding prevents you from getting shocked when you touch the charger. Quality insulation keeps the electrical current flowing only through the correct paths.
If you’re buying an outdoor charger, ETL checks its weather resistance. They look at NEMA ratings such as NEMA 3R or 4. These ratings tell you if your charger can really handle bad weather. ETL makes sure that “weatherproof” labels are accurate and that water can’t get inside and cause electrical problems. Your charger should keep working through rain, snow, extreme heat, and freezing cold. It also needs to resist damage from constant sun exposure.
Heat control is another critical test. Level 2 chargers pull high amounts of electricity for hours at a time. This creates a lot of heat. If the charger’s parts can’t handle the temperature, the plastic case might melt. Even worse, it could damage where you plug it into your car. A safe charger stays cool even during long charging sessions. Overheating chargers can become fire hazards.
ETL inspects the emergency stop functions too. You need a way to shut down the charger fast if anything goes wrong. This feature could prevent injuries or damage in an emergency situation.
The final test looks at how tough the charger is built. The cables, connectors, and outer shell need to hold up for years. They can’t crack, snap, or wear out from regular use. All these tests working together guarantee that every component of your charger meets safety standards.
Because every charger in this grid carries ETL certification rather than a range of certification tiers, the buying decisions here are about feature set, amperage, and installation type rather than safety level, and the ETL mark itself serves as the baseline that clears all those units for legal home installation.
The ETL control number on the product label is the key to confirming the certification is genuine, since searching it at the Intertek directory returns the manufacturer and the testing standard if the listing is valid. Counterfeit ETL marks are less common than counterfeit UL marks because the ETL brand has less consumer recognition. Still, they do appear on imported chargers, so verifying an unfamiliar brand before purchase is a two-minute step worth taking.
Several ETL-listed chargers also carry ENERGY STAR certification, and owning both marks means the charger has passed independent safety and efficiency testing, which is the combination most utility rebate programs require. Because stacking the federal tax credit and a utility rebate can offset a large part of the install cost, checking whether an ETL charger is also ENERGY STAR certified is worth doing before finalizing the purchase. Our ENERGY STAR-certified charger page lists the rebate programs and qualifying models.
Many of the strongest performers in this ETL category are European brands that arrived in the U.S. market with Intertek certification already in hand from their European testing. Because European electrical standards tend to emphasize cold-weather durability, several ETL-listed chargers carry colder operating temperature ratings than comparable UL-only units. For buyers in northern states or Canada-adjacent markets, the ETL category tends to have more options rated to minus 40 degrees Fahrenheit than the UL category does.
The NEC (National Electrical Code) requires licensed electricians to install only “listed” equipment. If they install a non-certified charger, they are violating the code. Most local electrical codes and building regulations accept ETL-listed electrical equipment as meeting safety standards. Installing a non-certified charger could violate code, fail inspection, or even void your homeowner’s insurance.
In the rare event of a garage fire, insurance adjusters look for the certification mark. If the device causing the fire wasn’t safety-tested by an NRTL, the insurance company has a strong legal ground to deny the claim. Many insurance companies specifically require third-party safety certification for high-power electrical equipment. Using an uncertified charger could complicate claims if an electrical fire or other incident occurs.
EV chargers operate at high voltages (240V for Level 2 chargers) and high currents (up to 80 amps). That’s a lot of electrical power flowing through equipment in your garage or driveway. ETL certification provides confidence that the charger won’t pose fire or shock hazards to your family.
Utility companies like PG&E and ConEd want to ensure the grid is safe. They almost universally require ETL or UL listing plus ENERGY STAR certification to qualify for their rebate programs, which can range from $250 to $1,000. Choosing a non-certified charger could cost you hundreds of dollars in potential incentives.

Look for the ETL listed mark, a circle with “ETL” in the middle, on the product itself, usually on a label affixed to the charger housing. You should also find a control number (7 digits) on the back of the unit. You can verify this number on Intertek’s official directory to confirm authenticity.
You’ve Got ETL Listed EV Charger Questions, We’ve Got Answers.
Yes, because both marks require testing to the same UL 2594 safety standard and both testing organizations hold NRTL status under OSHA, which gives both marks identical legal standing under the National Electrical Code. The lab performing the tests is different, but the standard and acceptance criteria remain the same.
In nearly all cases, yes, because licensed electricians are trained to recognize any NRTL mark as satisfying the listing requirement under NEC 110.3(B), and ETL is one of OSHA's recognized marks. A small number of inspectors default to UL out of habit, and if that happens, the manufacturer can provide documentation of ETL's NRTL status to resolve any concern.
Find the ETL control number on the product label and search it in the Intertek Directory of Listed Products. A valid listing returns the manufacturer name and the product category, confirming the certification is genuine. The search is free and public, and every product in our grid has passed this verification before inclusion.
Tesla chose Intertek for some Wall Connector certifications because Intertek's certification timeline better fit Tesla's product launch schedules, not because UL's testing is more rigorous. Both marks indicate that the product meets the UL 2594 standard, so a Tesla Wall Connector with an ETL mark is equally certified from a safety and code standpoint.
ETL certification alone usually does not qualify for utility rebates, as most rebate programs require ENERGY STAR certification as the qualifying criterion. Still, some ETL-listed chargers also carry ENERGY STAR certification. Check the ENERGY STAR database and your utility's rebate program terms to confirm which certification combination your program requires.
When an ETL listing also covers the CSA C22.2 standard, yes, and many Intertek certifications cover both standards simultaneously because the two are harmonized. Confirm the specific listing covers CSA if a Canadian installation is the goal, since a U.S.-only ETL listing may not satisfy the Canadian Electrical Code without the additional CSA coverage.
Stop using the product, document the control number that returned no result in the Intertek directory, report the seller to Intertek's brand protection team, and return the product for a refund. A charger with a counterfeit ETL mark has no verified safety testing and should not be connected to household wiring.
Yes, connector compatibility is independent of certification, so any ETL Listed charger with a NACS connector works directly with a Tesla, and a J1772 charger works with a J1772-to-NACS adapter. The ETL mark does not affect which vehicles the charger is compatible with.
Both terms refer to the same Intertek certification, with ETL Listed being the precise technical term and ETL Certified being the more marketing-friendly version used by some manufacturers. The underlying certification document and verification process are identical regardless of which phrase appears on the product.
