How to distinguish the original charger Xiaomi from a fake: 12 proven ways

With each passing year, counterfeit chargers are becoming more sophisticated, copying not only the appearance but also packaging, labeling, and sometimes even serial numbers. According to Xiaomi Russia, up to 40 percent of charging sold on marketplaces under the Mi or Redmi brand is counterfeit.

In this article, we will discuss 12 key differences between the original Xiaomi chargers and fakes, from visual details to technical tests. QR-code, what does marking mean MDY-12-ES, And why even a box can give you a counterfeit, and at the end, there's a list of trusted sellers where the risk of getting a fake is minimal.

1.Packaging: 5 signs of counterfeiting that are immediately visible

Xiaomi’s original box is not just cardboard: it’s protected from counterfeiting with holograms, embossing and even microtext. Counterfeiting often saves on the little things that catch your eye when you look closely.

• 📦 Print quality: The original packaging is clear, blurry. Counterfeiting is often caused by uneven paint or color shift. Check the Mi or Redmi labels, they should be perfectly flat.
• 🔍 Hologram: The original box (usually on the end) has a rainbow-effect holographic sticker, which flickers when you change the angle of view, and the fakes either don't have a hologram or look like a shiny film.
• 📏 Embossed: Xiaomi's logo on the original packaging is bulging - it can be felt with your fingers.Fake boxes often print the logo flat or with barely noticeable relief.
• 📌 Barcode and QR: The original box has a barcode that's laser-painted, not printed. Swipe it with your nail -- if the paint is erased, it's a fake. QR-The code must be sent to the official website of Xiaomi (domain mi.com).
• 📝 Serial number: There should be a unique box at the bottom SN (for example, 22081A1C03012345). It can be checked out on the Mi Verify website, where fakes often use repeating numbers or don't specify them at all.

⚠️ Warning: Fraudsters sometimes repackage fakes into original boxes from other Xiaomi devices (e.g. headphones or powerbank).Always check the model match on the box and the adapter itself!

2. Appearance of the adapter: details that give off fake

Even if the box looks perfect, the adapter itself could be a fake.The original Xiaomi chargers have strict build standards that are difficult for pirate manufacturers to replicate.

Let's start with the hull:

• 🔧 Material: The original is made of matového plastic with a soft touch. Counterfeiting is often made from glossy or rough plastic that creaks when compressed.
• 🎨 Color: Xiaomi's white adapters are warm (with a slight yellow) rather than cold bluish. Black models must be deep matte without shine.
• 📐 Geometry: The original has all the corners and ribs perfectly smooth. Counterfeiters often have burrs or asymmetrical fork holes.

Now connectors and contacts:

• ⚡ USB-Port: In the original adapters, the USB-Type C or Micro-USB connector (in older models) has golden contacts with perfectly flat edges.
• 🔌 Fork: European models (EU plug) pins of the fork should be 4 mm thick and rounded edges. Counterfeit saves on copper - pins are thinner (3.5 mm) and can bend.

💡

To check the weight of the adapter without weights, compare it to a coin: the original charging Xiaomi 20 watts weighs about 5 coins at 5 rubles.

3. Marking: What should be written on the original adapter

The back of Xiaomi’s original charger is marked with detailed markings that include model, power, certificates and factory code, and counterfeits often simplify or distort this data.

Consider the Mi 20W Fast Charge (MDY-12-ES):

• 📋 Adapter model: Must match the box (e.g, MDY-12-ES, ADP-40WY). Counterfeit codes write similar but non-existent codes (e.g., fake codes, MDY-12-EU).
• ⚡ Power: Indicated in W (W) and B/A (V/A). Original: 5V≈3A / 9V≈2.22A / 12V≈1.67A. Counterfeiting often understates the meaning (for example, 5V≈2A) or write round numbers.
• 🏭 Factory code: Starts with letters HCN, CMIT or CCC (For example, China: HCN: G22081A1C03. For counterfeits, the code is either missing or consists of random numbers.
• 📜 Certificates: Mandatory marks CE, RoHS and UKCA (Forgeries can forge these signs, but they are often blurred or crooked.

The critical sign of fake: if the adapter says "Made in China" but there's no Chinese CCC certificate, it's 100% fake. The original Xiaomi for China always has that sign.

Name of the model, for example, MDY-12-ES)|Power in W and B/A|Factory code (HCN, CMIT)|Certificates CE, RoHS, UKCA|Country of production and mark CCC (China)-->

4. Verification of QR-code and serial number

The most reliable way to check the originality is to scan. QR-But the scammers have learned to fake them, so it's important to know the nuances.

How to check on QR-code:

1. Find it. QR-code on the box or adapter itself (usually on a labeled sticker).
2. Scan it with the Mi Home app or any other QR-scanner.
3. The link should lead to the mi.com page with information about the model, and if an unknown site (for example, mi-shop.ru) opens, it is a fake.

Check by serial number (SN):

1. Find the SN on the box or adapter (format: 10-12 characters, for example 22081A1C03AB).
2. Go to the Xiaomi verification page.
3. Enter the number and the captcha. The original device will show the model, the date of production and the status of the warranty.

⚠️ Warning: Scammers sometimes clone serial numbers from original devices, and if a site shows that the adapter is already activated in another country (e.g. India, and you are in Russia), this is a cause for suspicion.

5.Technical tests: how to check charging with a multimeter

If the visual check fails, you can test the adapter with a multimeter or specialized applications, which will help to identify fakes that copy the appearance, but not the specifications.

Testing of voltage and current strength:

• 🔌 Connect the adapter to the socket without loading (do not connect the phone!).
• 📊 Set the multimeter in constant voltage measurement mode (DC) up to 20 V.
• 🔴 Connect the probes to the contacts +5V (red GND (black USB-plug.
• ✅ The original adapter will show 5.0-5.2 V. Counterfeit can produce 4.5 V or 5.5 V and higher, which is dangerous for the battery.

Load check (for experienced users):

• Connect the adapter to the phone and measure the current in DC 10A mode.
• The original charging Xiaomi 20W should give 3.0-3.5 A at 5 V. Counterfeiting rarely exceeds 2.0 A.
• Use apps like AccuBattery or Ampere to monitor real power.

💡

If the adapter warms more than 50°C when charging or emits a high-frequency squeak, this is a sure sign of a fake. Xiaomi’s original chargers work almost silently and heat up to 40–45°C maximum.

6.Where to buy: official and vetted sellers

Even if you know all the signs of counterfeiting, it is easier to avoid the risk by buying chargers from official partners. Here is a list of reliable sources (current for Russia and the CIS for 2026):

• 🏬 Official store Mi Store: mi-store.ru or mi.com/ua. Here. 100% Original but higher than the market price 10–15%.
• 🛒 Authorized Resellers: Svyaznoy (Series "Premium") M. Video (Section "Original Accessories") Citilink (marked "Official Xiaomi")
• 🌍 Foreign stores with warranty: AliExpress (only sellers with a rating of 98%+ Amazon (tag: "Ships from and sold by Amazon")

What to avoid:

• 🚫 Marketplaces (Wildberries, Ozon, Yandex Market) without the mark "Original" Even top sellers are up to 30% of fakes.
• 🚫 Social media (VK, Telegram, Instagram. 99% of "beneficial offers" are counterfeit.
• 🚫 All-phone shops or stalls, often selling repackaged fakes for the price of the original.

⚠️ Warning: On AliExpress, scammers sometimes say "100% original" in the description, but send a fake. Always check reviews with photos and videos where customers show the package and adapter close by.

7.What happens if you use a fake charger

Not only do counterfeit adapters slow the charge of the phone, they also cause irreversible damage to the battery and the device itself, and these are the real consequences that users face:

• 🔋 Battery degradation: Counterfeiting often produces unstable voltages, resulting in battery bloating or capacity reductions of 30-50% in 6 months.
• 🔥 Overheating and fire: Cheap components can't withstand the load, according to Rospotrebnadzor, 12% of fires from electronics in 2023 are associated with poor-quality charging.
• ⚡ Charging port damage: Incorrect current can melt contacts in the phone. repair costs 3-5 thousand rubles.
• 📉 Decreased performance: Unstable power leads to trottling (automatically reducing processor power), especially in games.

Real case: Redmi Note 11 user used a fake 33W charger for a month, the result: the phone stopped turning on, the diagnostics showed a short circuit in the power circuit, repairs cost 8 thousand rubles — almost like a new smartphone.
