How to Spot a Fake Charger or Cable

Why a fake charger is more than a slow charger

A charger's job is to turn household power into a small, steady current your phone can safely use. Well-made chargers have proper insulation, spacing between high- and low-voltage parts, and protection circuits that shut things down if something goes wrong.

Counterfeit and uncertified chargers often skip those parts to save money. The result can be overheating, melting plastic, electric shock or fire. On the phone side, unstable power can stress the battery and damage the charging port or charging circuitry.

Check for safety certification marks

In Canada, electrical products that plug into the wall should carry a mark from an accredited certification body. Common ones include CSA, cUL and cETL. The small "c" means the product was certified for Canada.

Look for the mark moulded or printed on the charger itself, not just on the box. Counterfeiters sometimes copy logos too, so treat this as one check among several rather than proof on its own.

iPhone cables: MFi and USB-C

For Lightning cables and accessories, look for Apple's MFi ("Made for iPhone") badge on the packaging. Certified Lightning cables include a small chip the iPhone recognizes. Uncertified ones often trigger the message "This accessory may not be supported," and may stop working after an iOS update. Apple's website has a lookup where you can check whether a brand and model are part of the MFi program.

iPhone 15 and later use USB-C instead of Lightning. For those, look for USB-C cables that are USB-IF certified, and a charger that supports USB Power Delivery (USB PD).

Samsung, Pixel and other USB-C phones

The same USB-C rules apply. A certified cable and a USB PD charger are the safe baseline. Samsung's Super Fast Charging uses a USB PD feature called PPS, so a charger that lists PPS support will charge newer Galaxy phones at their intended speed.

A badly made USB-C cable can deliver the wrong power, drop the connection or wear out the port faster. If a cable feels loose the moment you plug it in, that's a sign of a poorly sized connector.

Physical warning signs: a checklist

• Too light. Fakes often leave out internal components and shielding, so they feel hollow.
• Rough build. Seams that don't line up, visible glue, uneven plastic or a wobbly housing.
• Bad printing. Blurry, crooked or misspelled text, or missing model numbers and electrical ratings.
• Loose prongs. Wall prongs that wiggle or sit at slightly different angles.
• Poor connector fit. An end that's oversized, scratchy going in, or falls out easily.
• Suspicious packaging. Typos, low-quality photos, no manufacturer name or contact details.
• A deal that seems too good. A brand-name charger at a fraction of the usual price is a red flag.

Warning signs while it's in use

• The charger becomes too hot to hold comfortably. Slightly warm is normal; hot is not.
• Buzzing, whining or crackling sounds.
• A burning or melting smell, or discolouration on the plug or connector.
• Charging keeps starting and stopping.
• Your phone shows "accessory not supported" or says it isn't charging.
• The phone itself gets unusually hot while charging.

If you notice any of these, unplug it and stop using it. Never leave a suspect charger running overnight, and never charge on a bed, couch or under a pillow where heat can't escape.

Where fakes tend to turn up

Counterfeits often appear on online marketplaces from third-party sellers, in discount bins, and in listings that borrow a brand's official photos. Buying from the phone maker, a well-known accessory brand or a reputable retailer is the simplest protection. Keep your receipt and packaging in case something goes wrong.

What to do if you've been using one

1. Stop using the charger and cable. Take them to an electronics recycling drop-off rather than the garbage.
2. Look at your phone's charging port with a flashlight. Scorch marks, melted plastic or bent pins mean damage.
3. Try charging with a certified cable and charger you trust.
4. If the phone still charges slowly, intermittently or not at all, the port or charging circuitry may need repair.
5. Keep an eye on the battery. Rapid drain, heat or a lifting screen can mean it's been stressed.
