Video under the Baseus, Remax or nameless Chinese manufacturers, and they also mimic the original connector, while maintaining polarity and voltage.

When choosing, pay attention to:

• 🔌 Type of connector: Mi Band 1-4 requires an adapter with a “pinpin”, for Mi Band 5-8 – with magnetic contacts.
• 🔋 Voltage: should be 5V/0.5A (Charging the original. 1A or 2A They can reduce the battery life.
• 🛡️ Protection: quality adapters have built-in fuses against overheating and short circuit.

MicroUSB Charging: Not Suitable for All Models

The microUSB direct connection method only works for the Mi Band 1-4, and in these models the charging contacts are arranged so that they can be gently pressed against the cable connector, and for the Mi Band 5 and later, this method is not applicable, there is a magnetic connector with a different wiring.

Step-by-step instructions for Mi Band 1-4:

2. Remove the rubber plug from the bracelet and find the metal contacts.
3. Carefully press the bracelet contacts against the inner plates of the microUSB connector (not the outer: 🔴 Red wire (+) — right-hand. ⚫ Black wire (-) - left contact.

Secure the bracelet with tape or rubber band so that the contacts do not shift.

⚠️ Attention: If you confuse polarity, the bracelet can fail, and the risk of damaging the contacts with careless pressing. Mi Band 4 is especially sensitive to this method - it is better to use it only as a last resort.

Instructions:

1. Blow the wires on USB-cable: red (+5V) black (GND).
2. Attach magnets to the wires with tape so that they are attracted to the contacts of the bracelet.
3. Carefully attach the magnets to the back of the bracelet (where charging is usually attached).

• 🔋 The charging speed will be 2-3 times lower than the original cable.
• 💰 Cost of adapter (~600 ₽) comparable to the price of a new charge.

Method 2: Self-refining

For power users, you can sell a Qi module inside the bracelet by plugging it into the battery contacts.

• 🔧 Requires soldering and disassembly skills of electronics.
• ⚠️ Deprives of warranty and can lead to fire in case of error.
• 📉 Reduces battery capacity due to additional module.
