How to charge Xiaomi Mi Band without original charging: all ways 2026

The Xiaomi Mi Band fitness bracelet has become an indispensable assistant for millions of users, but its miniature charger is easily lost or fails. What to do if the original cable is lost and the bracelet is discharged to zero? In this article, we will discuss 7 proven ways to charge the Mi Band without native charging, including methods using improvised means and adapters from other devices.

It's important to understand that not all methods are equally safe. Incorrect charging can lead to contact damage, battery overheating or even a complete failure of the bracelet, and we will analyze each method in detail, indicate its pros and cons, and provide recommendations for minimizing risks. We will pay special attention to the Mi Band 3/4/5/6/7/8 models, as their design and connectors have key differences.

If you find yourself in a situation where the bracelet is dead and you don't have charge on hand, don't panic. In 80% of cases, the problem is solved using a standard USB- cable or even wireless charging (for new models), the main thing is to follow the instructions and not improvising with voltage.

1 Charging via USB- Cable: universal method for all models

The most affordable way is to use a standard USB- cable (such as from a smartphone) with an adapter or direct connection, which works for all versions of the Mi Band, but requires accuracy when connecting.

For the Mi Band 3/4/5/6 models, you will need:

• 🔌 USB- Micro-USB or Type-C cable (depending on adapter)
• 📌 Paperclip or thin metal object for fixing contacts
• 🔋 Power supply: computer, power bank or phone charger (5V/1A)

Algorithm of action:

1. Disconnect the bracelet capsule from the strap.
2. Take the USB- cable and expose the wires (red - +, black - - -).
3. Attach the bare ends to the contacts on the back of the capsule (see diagram below).
4. Secure the wires with a paper clip or tape to avoid breaking the contact.
5. Connect the cable to the power source.

Determine the polarity of the contacts (usually marked on the bracelet board)

Use a power source not exceeding 5V/1A

Make sure that the wires do not run between each other.

Do not leave the bracelet unattended while charging-->

Warning: this method requires precision. If you confuse polarity, the bracelet may fail. For the Mi Band 7/8, it is better to use magnetic adapters (see section 3).

2.Use of charging from other fitness bracelets

If you have a charger from another fitness tracker, there is a chance that it will be suitable for the Xiaomi Mi Band.

The table below shows the compatibility of chargers:

How to check compatibility:

• 🔍 Compare the connectors visually — they should match in shape and number of contacts.
• 📊 Check voltage: Mi Band requires 5V ± 0.2V.
• ⚡ Connect the charger and watch the indicator: if it catches fire, everything is fine.

💡

If the charge from the other bracelet is not tightly fixed, use a thin tape for additional fixation.This will prevent the contact from breaking during charging.

Warning: Do not use smartwatch chargers (such as the Apple Watch or Samsung Galaxy Watch) and their voltage and current can damage the Mi Band battery.

3 Magnetic charging: solution for Mi Band 7/8 and new models

Starting with the Mi Band 7, Xiaomi has switched to magnetic charging connectors, which has made it easier.

• 🧲 Use a magnetic charger from Xiaomi Smart Band Pro or Huawei Band 7.
• 🔌 Purchase a universal magnetic adapter (e.g., Qi-compatible).
• 🔋 Connect to wireless charging (only for Mi Band 8 Pro).

For magnetic charging:

1. Apply a magnetic connector to the back of the bracelet.
2. Make sure the charging indicator is on fire (usually red or green).
3. Connect the other end of the cable to the power source.

The Mi Band 8 Pro supports Qi wireless charging, but only with up to 2W. Using charging stations above 5W can lead to overheating.

4.A homemade adapter from an old charger for the phone

If you have unnecessary charging from your smartphone (such as Xiaomi Redmi or Samsung), you can remake it as the Mi Band, a method that requires minimal soldering or wire skills.

You'll need:

• 🔌 Charging from a phone (5V/1A or 5V/2A).
• 🔧 A soldering iron or crocodile clamps.
• 📏 Thin wires (e.g. from headphones).

Step-by-step:

1. Disassemble the charger and find the output contacts (+ and -).
2. Seal or fasten with clamps thin wires to contacts.
3. Connect the wires to the contacts on the bracelet (see the diagram for your model).
4. Set the connection with tape.
5. Connect the charger to the grid.

Note: If you are not sure about your soldering skills, it is better to use the method with USB- cable (section 1). Incorrect soldering can lead to short circuit.

5. Wireless charging: Does it work for the Mi Band?

Only the Mi Band 8 Pro officially supports Qi wireless charging, and for other models, this method either does not work or requires improvements.

How to charge Mi Band 8 Pro wirelessly:

• 📱 Use a Qi-enabled charging station (power no more than 5W).
• 🔄 Place the bracelet on the charger with the contacts down.
• ⏳ Wait for the charging indicator to appear (usually in 5-10 seconds).

For other models (Mi Band 3-7), wireless charging is possible only with homemade adapters:

• 🔧 Seal the coil from the wireless module to the bracelet contacts.
• 📶 Place the bracelet on a Qi charge.

💡

Wireless charging for the Mi Band 3-7 is an experimental method with a high risk of battery damage, and is recommended only in extreme cases.

If you decide to do this, remember:

• ⚡ The charging power shall not exceed 2W.
• 🔥 Watch the temperature of the bracelet - if overheated, turn off the power immediately.

6. Alternative power sources: power bank, solar panel, AA- batteries

In field conditions, when there is no access to the outlet, alternative power sources can be used:

• 🔋 Power bank: connect via USB- cable (method from Section 1).
• ☀️ Solar panel: with USB- output only and voltage stabilizer.
• 🔄 Batteries AA/AAA: via an adapter with a USB- port (e.g. for tourist lights).

Example of battery connection scheme:

1. Buy a 2×AA → USB adapter (sold in electronics stores).
2. Put the batteries in the adapter.
3. Connect the USB- cable to the adapter and the other end to the bracelet (as in the 1 section).

Warning: The voltage from the batteries must be 3V-5V. Using 9V batteries or 12V batteries will damage the Mi Band.

7.What to do if the bracelet is not charged?

If none of the methods worked, check the following points:

• 🔌 Contact state: Clean them with alcohol or eraser from oxidation.
• 🔋 Battery: If the bracelet does not respond to charging, it is possible that the battery is completely discharged (you need to hold on charging 10-15 minutes).
• 📱 Software glitch: Try resetting the bracelet through the Mi Fitness app (Device Profile → Reset).

If the bracelet is not charged:

• 🔧 Check the integrity of the cable with a multimeter.
• 📊 Make sure the power supply is giving 5V.
• 🛠️ Contact the service center (if the bracelet is warranty).

💡

If the Mi Band shows charging but the percentage is not increasing, try using another power source. Sometimes the problem lies in insufficient current (for example, when connecting to the USB- port of the computer).
