How to charge Xiaomi Mi Band 5 without original charging: working methods and life hacks

The situation is familiar to many: you take the Xiaomi Mi Band 5 out of the drawer after a long break, and the native charging is gone somewhere, or the contacts on the cable have become oxidized, and there is no place to buy a new one. What to do if the bracelet is dead and there is no standard way to recharge it? It turns out that there is a way out, and there is not one.

In this article, we will discuss all the working methods of charging the Mi Band 5 without the original cable, from the simplest (using improvised means) to the more complex ( soldering, adapters). Importantly, not all methods are equally safe. Some can damage the bracelet or even cause a short circuit. So we will not only describe the process, but also indicate the risks of each method, and also give checklists for checks before connecting.

If you’ve never done electronics repair, start with the most gentle options — for example, using charging from other Xiaomi models or universal holders. For experienced users, connection schemes via USB-Type-C or even a solar panel will come in handy.

Warning: All methods, except the use of original or compatible cable, can cancel the warranty on the device.

1.Use of charging from other Mi Band models

The most obvious and safe way to do this is to try out the charging cable from other Xiaomi fitness bracelets. Not all models are compatible, but some will work without any improvements.

Here is a list of devices that might be suitable for the Mi Band 5:

• 🔌 Xiaomi Mi Band 4 – full compatibility in connector and voltage (5V, 0.1A). The only difference is the shape of the clips, but the contacts are identical.
• 🔌 Xiaomi Mi Band 6 – suitable, but it may require careful positioning of the bracelet in the holder due to the modified body design.
• ❌ Xiaomi Mi Band 3 and older – not compatible due to a different type of connector (round vs rectangular).
• 🔌 Amazfit Bip U or Amazfit Bip U GTS 2 Mini – some users confirm performance, but the voltage may vary (check multimeter!).

If you have a charger from the Mi Band 4/6, Just insert the bracelet into the holder and connect to USB-port 5V/1A. Charging should start automatically. If the indicator on the screen does not light up, try it:

1. Clean the contacts of the bracelet and charging with an alcohol napkin.
2. Change. USB-port or adapter (sometimes power is lacking).
3. Turn the bracelet in the holder - the contacts should fit tightly.

⚠️ Note: Do not use chargers from devices with higher voltage 5V (For example, from the power bank to 9V/12V). This can burn the power controller of the bracelet.

2. Charging through a universal holder for smart watches

There are universal charging docks for fitness bracelets and smartwatches on sale that are suitable for the Mi Band 5. They are equipped with adjustable contacts or magnetic holders.

Examples of such devices:

• 🛒 Universal charging base with spring contacts (for example, Baseus or UGREEN). Suitable for most bracelets with flat contacts.
• 🛒 Magnetic USB-Nillkin cable magnetized to the metallic body of the Mi Band 5 and transmits charge through the contacts.
• 🛒 Pogo-pin charging adapter (sold on AliExpress as a "universal charger for fitness bracelets").

How to use:

1. Connect the universal holder to USB-port.
2. Place the Mi Band 5 in the docking station so that the bracelet contacts match the charging contacts.
3. If charging does not begin, slightly move the bracelet - sometimes you need to find a "point of contact".

Pros of the method: safe, does not require disassembly of the bracelet, suitable for regular use. Cons: you need to buy an additional device (cost from 300 to 1000 rubles).

3. Connecting directly to USB through the wires (for experienced)

If you are ready to tinker with a soldering iron or at least know how to work with wires, you can connect Mi Band 5 directly to the air. USB-This is a method that requires care, but it's almost free.

What you need:

• 🔧 soldering iron (or conductive glue).
• 🔧 Multi-core wire (for example, from unnecessary wire) USB-cable).
• 🔧 Multimeter (to check polarity).
• 🔧 Strain or shrink tube.

Connection diagram:

On the back of the Mi Band 5 (under the strap) there are two charging contacts. USB-port as follows:

Step-by-step:

1. Cut off the unnecessary USB-cable and clean the wires (only red and black are needed).
2. Seal the red wire to the left contact of the bracelet, black to the right.
3. Insulate the bare areas to avoid short circuits.
4. Connect the other end of the cable to USB-port of the computer or charger.

⚠️ Note: If you confuse polarity (+ Before soldering, check the multimeter, where the plus and minus are on the contacts of the bracelet (in constant voltage mode).

Charging via Type-C or Micro-USB adapter

On the Internet, special adapters are sold that allow you to connect the Mi Band 5 to standard Type-C or Micro-USB connectors. They look like a small plastic box with contacts for the bracelet on one side and a standard connector on the other.

How it works:

• 🔌 The adapter connects to a charger or powerbank.
• 🔌 The bracelet is inserted into the holder on the adapter (similar to the original charging).
• 🔌 Charging with standard parameters begins (5V/0.1A).

Where to buy it?

• 🛒 AliExpress (Search for "Mi Band 5") USB adapter").
• 🛒 Wildberries or Ozon (in the accessories section for Xiaomi).
• 🛒 Radio stores (sometimes marketed as "universal fitness adapters").

Pros: you do not need to disassemble the bracelet, the adapter can be used repeatedly. Cons: price (from 500 rubles), the risk of running into a low-quality product.

💡

Before buying an adapter, check the reviews - some models warm up while charging. The best option is an adapter with a metal body for better heat sink.

5. Alternative power sources: solar panel, powerbank, batteries

If you're not on hand USB-But there are other power sources, so you can try charging the bracelet from them (5V) polarity.

Option 1: Solar panel

Small solar panels (such as from a garden light) can produce enough current to charge the Mi Band 5.

1. Connect the panel to the bracelet through wires (as in the method with the USB).
2. Place the panel under a bright light (sun or powerful lamp).
3. Charging will go very slowly (a few hours), but in an emergency will be useful.

Option 2: Batteries. AA/AAA

You can build a simple circuit of two batteries AA (1.5V each = 3V And the resistor to limit the current, but it's a very risky method, and the voltage is lower. 5V may not start charging, and without a resistor, overheating is possible.

Option 3: Powerbank with USB-exit

If you have an external battery but no cable, you can:

• 🔋 Use the method of soldering wires directly to USB-port.
• 🔋 Buy an adapter USB → pogo-pin (as in section 4).

⚠️ Note: Do not connect the bracelet directly to the car lighter (12V) router-powered (9V/12V). Even through the resistor, it can damage the battery.

Charging through an induction coil (wireless method)

Theoretically, Xiaomi Mi Band 5 can be charged wirelessly using an induction coil from an old Qi-enabled smartphone.

• ⚡ Small battery size bracelet (only 125 mAh).
• ⚡ No built-in Qi receiver in Mi Band 5.
• ⚡ Low energy efficiency for such small devices.

How to try it (if you really want to):

1. Disassemble the bracelet and find the contacts of the battery.
2. Seal wires from the induction coil (for example, from a broken Xiaomi smartphone with Qi) to them.
3. Place the bracelet on wireless charging for the phone.

This method is not recommended due to the high risk of damage to the board, it is better to use it only as a last resort if there are no other options.

💡

Wireless charging for the Mi Band 5 is an experiment, not a reliable method, and it's 90 percent easier and safer to use a solder or a universal adapter.

7 What to do if the bracelet is not charged in any way

If you’ve tried all the techniques, but the Mi Band 5 stubbornly doesn’t want to charge, the problem may be:

• 🔋 Battery – over time, lithium-polymer batteries lose capacity and can fail.
• 🔧 Power controller – if the bracelet has been subjected to mechanical stress or overheating.
• 💧 Oxidized contacts – especially if the device has been in water or humid environment.

Diagnosis:

1. Try to clean the contacts of the bracelet and charging with alcohol or eraser.
2. Check the multimeter voltage on the contacts of the bracelet when connecting the charging (should be ~5V).
3. If the bracelet does not respond at all, connect it to the USB and check if it is defined as a device in the computer task manager (an unknown device should appear).

If the bracelet is not charged, there are two options:

1. Contact the Xiaomi service center (if the device is warranty).
2. Buy a new battery and replace it yourself (cost) ~500 rubles, rations skills are required).
