⚠️ Note: If the box says "Made in China" but does not have the manufacturer's address or importer's data, it is 100% fake.

Body and assembly: parts that give rise to counterfeiting

Even if the packaging looks perfect, the case of the device can be counterfeited. The original Mi Power Bank is characterized by perfect fitting of parts and using quality materials.

• 🔧 The gaps between the parts of the case: the original does not. Counterfeiting often have visible gaps, especially around the switch button.
• 🎨 The color and texture of the plastic: the original uses matte plastic with a uniform color.
• 🔢 Labeling on the case: at the bottom of the original device, the serial number, model and certification data are engraved (CE, On fakes, these inscriptions are often painted with paint that is erased.

3. USB ports and connectors: technical nuances

One of the most difficult things to fake is USB-In the original devices, they are manufactured with high precision, whereas in fakes, they often save on small things:

• ⚡ Quality of the soldering: in the original contacts USB-The ports are flat, without solder marks, and the counterfeits may have uneven or oxidized contacts.
• 🔌 The density of the cable: insert the charging cable into the port. In the original, it holds tight, without backlash. In fakes, the connector often hangs around.
• 📊 Port Marking: Original Mi Power Bank models 4 ports are marked as USB-A (Quick Charge and USB-C (Input/Output). Forgeries, the inscriptions may be missing or curved.

The most common fraud with fake Mi Power Banks is overcapacity, such as a device labeled as 20,000 mAh, and in fact gives no more than 10,000-12,000 mAh.

• 🔋 Discharge test: fully charge the power bank, then discharge it through a device with known consumption (for example, a smartphone with a battery of 4000 mAh). the original Mi Power Bank 3 Pro (20000 mAh) should fully charge such a smartphone 4-5 times.
• 📉 Monitoring applications: Use programs like AccuBattery (Android) or CoconutBattery (iOS) to measure your actual energy output.
• 🔧 Body autopsy: If you're willing to sacrifice the warranty, you can gently open the case and look at the battery marking.The original Xiaomi batteries have a logo ATL Lishen (manufacturers that supply components for Xiaomi).

Note the weight of the battery. Capacity is directly related to weight: if the device is too light for the claimed 20,000 mAh, this is a sure sign of fraud. For example, the original 20,000 mAh battery weighs at least 180-200 g, whereas in counterfeits this figure is often underestimated by 1.5-2 times.

⚠️ Warning: Some counterfeits use inflated batteries, batteries with artificially high voltages that drop rapidly after the first charging cycles, which can fail after 2-3 months of use.

5.Indication and electronics: hidden signs

Pay special attention to the sound signals. The original Xiaomi models do not make any sounds when you plug in or turn off the load. If your power bank beeps or clicks, it is a fake with cheap electronics.
