Buying Xiaomi Power Bank is always a risk of getting a fake, especially if you choose a device on marketplaces or from unverified sellers. According to Counterpoint Research 2023, up to 30% of Xiaomi accessories in the secondary market are counterfeit. Fake power banks not only hold their charge worse, but can also explode due to poor-quality batteries or protection schemes. In this article, we will analyze 7 reliable ways to verify originality, including visual signs, tests through official Xiaomi services, and even physical experiments with a multimeter.
It's important to understand that fraudsters are constantly improving fakes by copying packaging, fonts and even holograms. So a visual inspection is not enough, you need a comprehensive check on several criteria. We have compiled current methods for 2026, given the latest updates to Xiaomi's verification system and typical tricks of counterfeit manufacturers. If you have already bought a power bank and doubt its authenticity, follow all the steps from this manual - it will take no more than 15 minutes.
1.Packaging check: 5 parts that are the worst forged
Packaging is the first and most obvious sign of the original. Counterfeit Power Banks often come in boxes with blurry fonts, crooked seams, or color mismatches.
- π¦ Material box: Original - matte cardboard of high density (does not bend when compressed), fake - glossy or thin paper with roughness.
- π Fonts and logos: The original Mi is clear, with uniform lines thick, and forgeries often blur the letter angles or indentation between characters.
- π¨ Color gamut: Xiaomi's original boxes use the Pantone 186 C for orange (deep, no reddish hue) counterfeits are usually brighter or paler.
- π Hologram: The original packaging of the hologram changes color when tilted (from green to blue), not just shiny.
- π Box sizes: Compare it to the official model settings. For example, Mi Power Bank. 3 Pro 20000mAh box 16.5 Γ 8.5 Γ 3.5 see the deviation more than 2 mm - cause for doubt.
Pay special attention to the model article on the box. The original Xiaomi Power Bank has 11 characters (example: MDY-12-EM). Counterfeit codes like the PB20000 often use simplified codes or omit them altogether. Check the article on Xiaomi's official website - if there is no model with such code, you are 100% counterfeit.
Serial number and QR-Code: How to check through official services
Each Xiaomi Power Bank has a unique serial number (SN) and QR-This is a code linked to the manufacturer's database, and you can check it through official tools:
- Find the serial number: It is listed on the sticker under the box (format: 12 digits and letters, for example L3N7A1B2C3D4) and duplicated on the powerbank itself under the label.
- Scan it. QR-Code: Use the Mi Home app (Devices section) β Add it manually. β Power Bank. The original code will redirect you to the product page with specifications.
- Check on Xiaomi's website: Go to the verification page, type in SN and CAPTCHA. The system will show the status of the device.
β οΈ Warning: Fraudsters have learned to fake QR-codes that lead to real Xiaomi pages, but with other people's serial numbers. SN It's a sticker with what's displayed after the scan, and if they don't match, it's a fake.

Compare them to matching symbols
Check out SN via Mi Home and official website
Make sure the model in the database matches yours.-->
If the serial number doesn't pass verification, but the packaging looks perfect, you may be dealing with a "premium replica" that even copies holograms, but uses the broken SNs from other devices, in which case only physical verification (see section 5) will help.
3.Visual inspection of power bank: 8 signs of forgery
Even if the packaging and documents look perfect, the power bank itself can issue a fake.
| Sign. | Original | Fake. |
|---|---|---|
| Case material | Matte plastic with soft touch, without barbs | Glossy or rough, with sharp edges |
| Weight. | Corresponds to the stated (for example, 20000mAh weighs 350-370 g) | Too light (battery of less capacity) or heavy (cheap metal) |
| Charge indicators | 4 LEDs with smooth switching, uniform lighting | 2-3 LEDs, flicker or burn dimly |
| USB ports | Tightened tight, without backlash, with laser engraving | Whistleblower, with gaps, inscriptions erased or painted |
| Inscriptions on the hull | Clear, uniform relief, no typos. | Blurred, with errors (e.g., "Made in Chna") |
Note the smell: the original Xiaomi power banks do not smell of chemicals or plastic. The pungent smell may indicate cheap glue or poor-quality batteries. Also check the equipment - only the cable (if provided) and the manual should be in the box. The presence of additional adapters or cases often indicates a fake (the original does not include them).
What to do if the power bank has already been used?
4. Charging test: how to detect a fake by speed and capacity
The most reliable way to test is through practical tests, and fakes often underestimate the actual capacity of the battery or use cheap controllers that limit the current.
- π± Smartphone with Quick Charge support 3.0/4.0 (for example, Xiaomi 12 Pro or Redmi Note 11).
- β‘ Cable USB-C to USB-C (Type-C models or the original Xiaomi cable.
- β±οΈ Stopwatch or current measurement application (e.g. AccuBattery).
Instructions for testing:
- Completely deplete the power bank (indicators must go out).
- Connect it to an 18W+ charger and keep the time up to 100%. The original Mi Power Bank 3 20000mAh charges in 6-7 hours, the fake charges in 3-4 hours (due to less real capacity).
- Connect the power bank to a discharged smartphone and measure the current through AccuBattery. The original gives stable 2.4A-3A, the fake gives galloping values of 1A-1.5A.
- Count how many full chargers a smartphone provides powerbank. For example, 20000mAh must charge Redmi Note 10 Pro (5020mAh) at least 3 times. Counterfeit often gives 1.5-2 charges.
β οΈ Warning: Some fakes mimic fast charging, but actually overheat.If the power bank case heats up above 40Β°C when charging your smartphone is dangerous! Turn off the device and don't use it any further.
π‘
For an accurate test of capacity, use USB-Tester (e.g. Xiaomi) USB Put it between the power bank and the smartphone, and it shows the real mAh that the battery is giving off, and if it's 20 percent or more below the declared value, it's a fake.
5. Multimeter Verification: for Advanced Users
If you have a multimeter, you can check the internal resistance of the battery and the voltage at the outputs. This is the most accurate method, but it requires caution:
Step 1. Voltage check:
- Put the multimeter into DC 20V mode.
- Connect the probes to the + and - outputs of the power bank (use the USB-A or Type-C connector).
- The original Xiaomi Power Bank voltage should be 5.1V Β± 0.1V. Counterfeiting often gives 4.8V-5.3V (which is harmful to smartphones).
Step 2: Resistance test:
- Switch the multimeter to Ξ© (200Ξ©).
- Touch the battery contacts (if available) or the battery contacts with probes. USB-port.
- The original controller resists 0.1-0.3Ξ©, and counterfeits have a resistance higher than 0.5Ξ©, which means cheaper components.
β οΈ Warning: Don't disassemble a power bank unless you're confident in your skills! Lithium batteries can ignite if damaged. If you find unmarked cells or a low-quality solder inside, stop using the device immediately.
π‘
Even if the multimeter is normal, it doesn't guarantee originality. Some fakes copy electrical parameters, but use poor-quality batteries that degrade in 3-6 months.
6. Check through the Mi Home app (new models only)
New Xiaomi Power Bank models (such as Mi Power Bank 4 or Mi Smart Power Bank) support connection to the Mi Home app, which allows you to authenticate and even update the controller firmware.
- Download Mi Home from Google Play or App Store.
- Sign up or sign in to your Xiaomi account.
- Click Add Device β Power Bank and follow the instructions.
- If the device plugs in and displays capacity, temperature and charging times, that's the original, and the fakes either don't plug in, or they show a "Device not supported" error.
You can also check the number of charging cycles in the app, and if the power bank is new, but it shows 50+ cycles, it's already been used or it's been tampered with, and the original devices have a cycle counter that you can't reset.
7 Where to buy to avoid getting a fake: checklist of safe sources
The best anti-counterfeiting protection is buying from a legitimate partner, and here's a list of proven sources for 2026:
- π¬ Xiaomi official store: mi.com or branded stores in your city.
- π Authorized resellers: Svyaznoy, M. Video, Citilink (check the availability of the certificate on the showcase).
- π Global marketplaces: Only sellers with the status of βOfficial Xiaomi Storeβ on AliExpress or Amazon.
- π Secondary Market: Only with a check, warranty card and the possibility of checking through Mi Home.
β οΈ Note: Avoid buying from sellers with:
- π© The original is here, but it works".
- π© Prices below 70% of the market average (e.g. Xiaomi) 20000mAh It's not worth 800. β½).
- π© Photo of goods without logos or with a blurred background.
π‘
If the seller refuses to provide a photo of the serial number before the purchase, this is a cause for suspicion. Original devices always have an SN, and its verification should not be a problem.
