How to Tell If Phone Chargers From Amazon Are Fake: 7 Checks
By Global Swanky | Last updated: October 13, 2026 | Safety tests and brand checks verified on October 13, 2026.
Here's how to tell if phone chargers from Amazon are fake, in seven checks to run before you plug in. A fake charger isn't just wasted money; it can be a shock or fire risk.
Key takeaways
- Check the Sold by line first: Amazon.com or the brand's own store is lowest risk.
- Genuine chargers show the maker, model and output ratings clearly on the case.
- Look for the MFi badge on Lightning gear and a UL or ETL mark on wall chargers.
- Fakes can be weighted with clay or metal, so heft alone proves nothing.
- If a new charger gets hot, buzzes or smells, unplug it and return it.
A fake phone charger is a counterfeit: a charger or cable sold under a brand's name or logo, usually Apple's, that the brand never made. An uncertified charger uses its own name but skips proper safety testing. These checks help you spot both.

How to tell if phone chargers from Amazon are fake: the quick version
Run seven checks: who's selling, the price, the box and paperwork, the markings on the charger, the certification marks, the plug pins and build, and the cable ends and charging behavior. Two or three red flags together almost always means a fake. With chargers, one serious red flag, like heat or buzzing, is enough to unplug it.
For how common fakes are, with Apple's lawsuit and lab results, see our report on fake phone chargers on Amazon. This guide is the hands-on checklist.
Here are the 7 checks in the order to run them:
- Check who's selling: Amazon's own stock or the brand's own store is lowest risk.
- Check the price against the brand's site and big electronics stores.
- Inspect the box, instructions and safety warnings.
- Read the markings on the charger: maker, model and output ratings.
- Look for real certification: the MFi badge, a UL or ETL mark.
- Check the plug pins, casing and weight.
- Inspect the cable ends, then watch the first charge closely.
Why chargers need extra care
In 2016, UL bought 400 counterfeit Apple chargers online for the UK Chartered Trading Standards Institute, and 397 failed a basic safety test. A fake charger is almost always a shock risk, so these checks matter more than they do for most products.
Check 1: Who's actually selling the charger?
Look at the Sold by line under the price before anything else. Chargers shipped and sold by Amazon.com, or sold by the brand's own store, carry the lowest risk. Third-party sellers carry the most, especially on listings claiming to be genuine Apple, though even Amazon's own stock was hit by fakes in 2016.
What to look for on the seller's profile
Open the seller's profile and check:
- Whether the name matches the brand's official store or Amazon.com.
- How long they've sold and how many ratings they have.
- Whether they sell named electronics brands or random unbranded gear.
- Recent feedback mentioning heat, sparks, burning smells or fakes.
Check authorized resellers
Apple publishes a list of authorized resellers, and many accessory brands do the same. If a seller isn't on the list and isn't Amazon.com, look harder at everything else.
Check 2: Is the price too good to be true?
Often, yes. Apple's 20W USB-C adapter sold for $19 in July 2025, Money Digest reported, while uncertified knockoffs on Amazon sold for far less. A genuine Apple or brand-name charger at a fraction of the brand's price is a red flag, and so is a no-name charger that seems impossibly cheap for its wattage.
Price alone can't clear a listing
Some fakes are priced near retail to look trustworthy. A normal price doesn't make a charger safe, so use price to rule listings out, never to rule them in.

Check 3: What do the box and instructions show?
A genuine charger comes with proper packaging and safety information. UK Trading Standards says user instructions should cover the conditions and limits of use, how to operate the charger safely, basic electrical safety and safe disposal. When Which? tested 15 marketplace chargers in 2026, every one was missing key information on the packaging, the charger or the documentation.
Packaging red flags
Treat these as warning signs:
- No instructions or safety warnings at all.
- Spelling mistakes or odd wording on the box.
- A brand logo on the box but no maker's name or address.
- A plain bag or blister pack for something sold as a genuine brand product.
Check 4: Do the markings on the charger look right?
Read the small print on the charger itself. Trading Standards says to look for the maker's name or logo, the model and a batch number, and BGR notes that missing output ratings are a sign of a counterfeit. UL even found fake Apple adapters printed with “Power A dapeer.”
What the label should show
On a genuine charger, expect to see:
- The maker's name or logo and a model number.
- Input and output ratings, such as volts and amps, that match the listing.
- Clean, correctly spelled text with even spacing.
- Safety marks printed or molded neatly, not as loose stickers.
Apple-specific tells
UL says all genuine UL-certified Apple adapters are white. If a charger sold as genuine Apple comes in another color or carries blurry print, treat it as fake.
Check 5: Is it properly certified?
Look for the right marks. Apple says certified third-party Lightning accessories carry the MFi badge on their packaging, and Money Digest notes the UL Listed and ETL Listed marks show a charger passed independent North American safety testing. But marks can be faked: Trading Standards warns the CE mark is easily forged.
The MFi badge for Lightning gear
MFi stands for Made for iPhone, iPad and iPod. Apple's guide to counterfeit Lightning accessories recommends using only accessories Apple has certified with the MFi badge, and Apple runs an online MFi accessory search where you can look up certified products.
UL and ETL marks for wall chargers
A UL or ETL mark means the design passed safety testing. Even so, in a 2018 government test buy, one supposedly UL-certified phone charger from a third-party seller turned out to be counterfeit, so a mark is a minimum, not a guarantee.
Check 6: How do the plug pins, casing and weight feel?
Check the physical build closely. UK Trading Standards suggests plugging the charger into a socket without switching on or connecting a device, because a charger that doesn't fit easily may have wrongly sized pins. Look for even seams and solid casing, but don't trust weight: Which? found 2026 fakes padded with modelling clay and metal weights.
Plug pins and fit
Pins should be straight, solid and the right size for your outlet, and the charger should seat firmly without wobbling. Trading Standards also specifies a minimum gap between the pins and the edge of the case for UK plugs, which shows how much spacing matters for safety.
Casing and seams
A genuine charger usually has tight, even seams and a solid shell. Gaps, rough edges, loose parts or a case that creaks when pressed are warning signs.
Why weight can fool you
In Which?'s 2026 tests, two chargers were filled with modelling clay and one with a metal weight to make them feel substantial, including a fake “Apple” 35W adapter. A heavy charger can still be a fake.
Check 7: Do the cable ends and first charge check out?
Inspect the cable connector, then watch the first charge. Apple says a genuine Lightning connector is one smooth piece with rounded contacts and a gray or metallic faceplate, while counterfeits often have squared contacts and a white or black faceplate. If the charger gets hot, buzzes, smells or charges erratically, unplug it at once.
Apple's Lightning cable tells
| Feature | Apple-branded cable | Counterfeit or uncertified cable |
|---|---|---|
| Lightning connector | Single piece, smooth finish | More than one piece, rough or uneven finish |
| Contacts | Rounded, smooth, gold- or silver-colored | Squared contacts with an uneven surface |
| Boot size | Consistent 7.7 mm x 12 mm | Varying width, length or thickness |
| Connector faceplate | Gray or metallic | White or black |
A genuine Apple Lightning to USB cable also has “Designed by Apple in California” and an assembly location printed about seven inches from the USB end, followed by a 12-digit serial number.
Watch the first charge
Charge a phone while you're nearby, on a hard surface, and unplug at once if:
- The charger gets hot to the touch within a few minutes.
- You hear buzzing or crackling, or smell burning plastic.
- Your phone charges erratically, shows an accessory warning or stops charging.
- The plug or connector feels loose in the socket or port.
Which? reported that one fake charger it tested made arcing sounds within about 10 seconds of use, which can cause fires, explosions or electric shock. Never leave a charger you're unsure of running overnight.
Quick checks when your charger arrives
Use this table on delivery day, before the charger goes anywhere near your nightstand.
| What to check | Usually on a genuine charger | Warning sign |
|---|---|---|
| Markings | Maker, model and output ratings printed clearly | Missing ratings, misspellings or blurry print |
| Certification | MFi badge on Lightning gear; UL or ETL mark on wall chargers | No marks, or only a CE mark |
| Instructions | Safety guidance and disposal advice included | No paperwork at all |
| Plug pins | Straight, solid, firm fit in the socket | Loose, bent or a tight, awkward fit |
| Casing | Tight seams, solid shell | Gaps, rough edges or rattling |
| First charge | Warm at most, quiet, steady charging | Hot, buzzing, burning smell or errors |
Which checks are hardest for fakes to pass?
The cable-end details and the first-charge behavior, followed by the markings. Boxes, weight and even certification marks are easier for counterfeiters to copy. The table below ranks each check by how often a convincing fake can slip past it, based on the tests and guidance cited here.
| Check | Can a good fake pass it? | Our reliability read |
|---|---|---|
| Seller | Not applicable | Best way to avoid fakes in the first place |
| First-charge behavior | Rarely for long | Strong warning sign, but test only while supervised |
| Cable connector details | Sometimes | Strong for Apple Lightning cables |
| Markings and ratings | Sometimes | Moderate to strong |
| Certification marks | Often, marks can be forged | A minimum, not a guarantee |
| Box and instructions | Often | Moderate |
| Weight | Yes, with clay or metal fillers | Unreliable on its own |
| Price | Yes, if priced near retail | Rules listings out, never in |
These are our reliability reads, not lab ratings. They follow UL, Trading Standards, Which? and Apple guidance.
Is a cheap unbranded charger always fake or unsafe?
No, an unbranded charger isn't a counterfeit, and in Which?'s 2026 test, two unbranded Amazon chargers at £2.99 and £3.99 passed electrical safety testing. But both still lacked the markings and paperwork needed for legal sale in the UK, so you had nothing to verify. A named brand with MFi or UL marks is the safer buy.
For portable power, our power bank buying guide and portable charger picks stick to named makers with proper certification.
What to do if your charger fails a check
Unplug it first, then document, return and escalate. Don't keep using a charger you suspect, especially overnight or near anything flammable.
Document everything
Photograph the markings, plug pins, cable ends, box and instructions, and screenshot the listing and the Sold by name.
Return through Amazon
Open the order in Your Orders and say plainly that you believe the charger is counterfeit or unsafe. Choosing that reason helps the report reach the right team.
File an A-to-z Guarantee claim if a seller stalls
If a third-party seller won't help, message them through Amazon first and give them 48 hours. Then file an A-to-z Guarantee claim, which you can do within 90 days of the latest estimated delivery date.

Frequently asked questions about spotting fake phone chargers from Amazon
How can I tell if my phone charger from Amazon is fake?
Run seven checks: the seller, the price, the box and instructions, the markings, the certification marks, the plug pins and build, and the cable ends and first charge. Missing output ratings, misspellings or a charger that gets hot or buzzes are strong signs. Unplug anything suspicious and return it.
Are chargers sold by Amazon.com genuine?
Chargers shipped and sold by Amazon.com are a low-risk offer, because Amazon itself is the seller rather than an unknown third party. But fakes reached Amazon's own stock through a supplier in 2016, so still check the markings, certification and cable ends when your charger arrives.
How do I know if an Apple charger is real?
Check that it's white, with clean print and correct spelling, and that the cable has Apple's printing about seven inches from the USB end with a 12-digit serial. A genuine Lightning connector is one smooth piece with rounded contacts and a gray or metallic faceplate, according to Apple.
What is the MFi badge?
MFi stands for Made for iPhone, iPad and iPod. Apple says certified third-party Lightning accessories carry the MFi badge on their packaging, and it recommends using only certified accessories. Apple also runs an online MFi accessory search where you can look up certified products before you buy.
Does a UL or CE mark mean a charger is safe?
It's a good sign, not a guarantee. A UL or ETL mark means a design passed North American safety testing, but Trading Standards warns the CE mark is easily forged, and a 2018 government test buy found a counterfeit charger carrying a UL certification. Combine marks with the other checks.
Why are some fake chargers heavy?
To feel genuine: in Which?'s 2026 tests, two marketplace chargers were filled with modelling clay and one with a metal weight, including a fake Apple 35W adapter. Buyers associate heft with quality, so counterfeiters add weight. A heavy charger can still be a dangerous fake.
Are fake chargers dangerous?
Yes. In 2016, 397 of 400 counterfeit Apple chargers bought online failed a basic safety test in UL testing for UK Trading Standards, and Which? found 9 of 15 marketplace chargers posed a shock risk in 2026. Unplug any charger that gets hot, buzzes or smells of burning.
How do I test the plug pins on a charger?
UK Trading Standards suggests plugging the charger into a socket without switching it on or connecting a device. If it doesn't fit easily, the pins may be the wrong size. Pins should be straight and solid, and the charger should sit firmly without wobbling or feeling loose.
What should I do if my charger from Amazon is fake?
Unplug it, photograph the markings, pins, cable ends and box, and start a return from Your Orders saying you believe it's counterfeit or unsafe. If a third-party seller doesn't help within 48 hours, file an A-to-z Guarantee claim within 90 days of the latest estimated delivery date.
Are cheap unbranded chargers on Amazon safe?
Some are: in Which?'s 2026 test, two unbranded Amazon chargers passed electrical safety testing, though they lacked the markings and paperwork needed for legal sale in the UK. Others failed badly. A named brand with MFi or UL marks gives you something to check and someone accountable.
Can I tell if a charger is fake before buying it?
Partly. Before buying, check the Sold by line, the seller's history and the price against the brand's site, and look for MFi or UL marks in the listing photos. The strongest checks, the markings, cable ends and first-charge behavior, only work once it arrives, so buy where returns are easy.
Is it safe to charge my phone overnight with a new charger?
Not until you've checked it: run the physical checks first, then charge while you're nearby on a hard surface for the first few sessions. If it stays cool, quiet and charges steadily, it's likely fine. Never leave a charger you're unsure of running overnight or near anything flammable.
The bottom line on spotting fake phone chargers from Amazon
If you want to know how to tell if phone chargers from Amazon are fake, stack the checks. The seller and price help you avoid fakes, while markings, certification, pins, cable ends and the first charge catch the ones that slip through.
Your next step: check the Sold by line on the charger you want before you buy. When it arrives, read the markings and inspect the pins and cable ends, then supervise the first charge before trusting it overnight.
