Power supply for Xiaomi camera: how to choose the right and not to burn the device

Why is Xiaomi’s standard power supply not always suitable?

You bought it. IP-Xiaomi Mi Home Security Camera or Xiaomi Smart Camera, but faced with a problem: the native adapter is lost, broke or simply does not reach the socket? or maybe you want to install a camera on the street, where you need a sealed power supply with moisture protection? In any case, choosing the right power source is not just a matter of convenience, but a guarantee of stable operation and safety of your device.

Many users mistakenly believe that any power supply with a suitable Micro-USB or USB Type-C connector is suitable for the camera, but this is not true: improper voltage, insufficient power or poor build can lead to overheating of the camera, malfunctions or even fire, especially for models with rotary mechanism support (Xiaomi Mi Home Camera 360°) or night vision, which consume more energy.

In this article, we will discuss:

• 🔌 Technical requirements for power supplies for Xiaomi cameras (voltage, current, connectors).
• ⚡ Typical selection errors and their consequences (from image flickering to camera failure).
• 🏆 Top.-5 Proven models of power supplies for different scenarios (home use, street installation, backup power supply).
• 🛠️ How to modify power for PoE cameras or battery models.

Technical specifications: what should be on the label of the power supply?

The first thing to look at is the power output settings. For most Xiaomi cameras, the standard requirements are as follows:

• 🔋 Voltage (V): 5V ± 0.25V — Even a small deviation can cause unstable work.
• ⚡ Current (A): minimum 1A (base-model), 2A for cameras with rotary mechanism or night vision.
• 🔌 Connector: Micro-USB (Old Models) USB Type-C (new cameras, for example, Xiaomi Smart Camera) 2K).

Important: if the power supply is specified 5V/2A, this means that it can output up to 2A, but the camera will only take what it needs (for example, 1A). However, using a lower current unit (for example, 5V/0.5A) is categorically impossible - the camera will work incorrectly or will not turn on at all.

Look at the power supply certification. Good adapters are labeled CE, RoHS or UL. Cheap Chinese units without certificates can not only damage the camera, but also cause short circuit.

⚠️ Note: Some Xiaomi cameras (e.g. Xiaomi Mi Home Camera 2) are sensitive to voltage pulsations. If the power supply produces a "dirty" voltage (with interference), the camera can spontaneously reboot or give artifacts in the video.

Top.-5 Power supplies for Xiaomi cameras: from budget to premium

We tested dozens of models and selected the best options for different tasks, all power supplies in this ranking meet the requirements of Xiaomi and have positive user feedback.

1. Original Xiaomi power supply (5V/2A, Micro-USB)

Pros: full compatibility, stable voltage, compact size. Cons: short cable (1.5 m), difficult to find on sale separately from the camera. Price: ~500-700 rubles. For whom: those who want a 100% guarantee of compatibility.

2. Baseus GaN 2 (20W, USB Type-C)

Pros: support for fast charging, compact size, high build quality. Cons: more expensive than analogues, excess power for most cameras. Price: ~1 200-1 500 rubles. For whom: owners of Xiaomi Smart Camera 2K or those who plan to use the unit for other devices.

3. Ugreen 5V/2A (Micro-USB, sealed)

Pros: protection from moisture (IP67), long cable (2 m), stable voltage. Cons: a little bulky. Price: ~ 800-1000 rubles. For whom: outdoor camera installation (for example, Xiaomi Outdoor Camera).

4. Anker PowerPort III Nano (5V/3A, USB Type-C)

Pros: ultra-compact, reliable brand, support for PowerIQ. Cons: high price. Price: ~ 1,500-1,800 rubles. For whom: those who value reliability and are willing to overpay.

5. Xiaomi Mi Compact Bluetooth Speaker Power Adapter (5V/2A, Micro-USB)

Pros: inexpensive, compatible with most cameras, easy to find on sale. Cons: leaky, short cable. Price: ~ 400-600 rubles. For whom: a budget solution for home use.

💡

For cameras with a rotary mechanism (360°) be sure to choose a power supply with a current of at least 2A - otherwise the engine will work in jerks or will refuse to turn at all.

Covers, extension cords and other accessories: what else can you need?

Sometimes one power supply is not enough, for example, if the camera is installed far from the socket or you need additional protection from moisture.

• 🔌 Extensioner with USB-port: allows you to extend power to a distance of 5 meters without voltage loss: UGREEN USB Extension (3m, Micro-USB).
• 🌧️ Sealed power supply case: protects the adapter from rain and dust.
• ⚡ PoE splitter: If your camera doesn’t support PoE directly, but you want to power it over a network cable, you can use a splitter (e.g., TP-Link). TL-POE10R).
• 🔋 Power Bank with Exit 5V: Important: The capacity must be at least 10,000 mAh.

If you use an extension cord, pay attention to the cable cross section. For a length of more than 3 meters, a cable with a cross section of at least 0.75 mm2 is recommended, otherwise there will be voltage drawdowns and the camera may work unstable.

Make sure the block voltage is exactly 5V (no deviations)

Check current: for cameras with motor – minimum 2A

Frequent Mistakes When Choosing a Power Supply Unit and How to Avoid Them

Even experienced users sometimes make mistakes that cause the camera to break down, and here are the most common ones:

1. Many people take a smartphone adapter, thinking that "everything is 5V." However, the current of phone charges is often lower (0.5A-1A), which leads to underpowering of the camera, especially in night mode.
2. Ignoring polarity: In rare cases (such as using unoriginal cables), a repolarization can occur, causing the camera to fail. Always check the markings on the unit and the camera.
3. Quality savings: Cheap power supplies without certificates often have unstable voltages, resulting in image flickering or overheating of the camera.

⚠️ Warning: If the camera starts to warm up more than usual after the new power supply is connected, turn it off immediately! This is a sign that the adapter is giving off high voltage or has poor stabilization.

Another common problem is the use of USB-Many hubs are not designed for long-term loading and can overheat. If you need to connect the camera to a hub (for example, to write to a hard drive), use a hub with separate power (for example, Anker). 7-port USB Hub).

PoE, batteries and other alternative power sources

Not all Xiaomi cameras support PoE (Ethernet power), but if your model is compatible (e.g. Xiaomi Mi Home Security Camera 2K Pro), this could be a great solution for:

• 🏢 Office or industrial installations where you need to minimize the number of cables.
• 🌳 Street cameras, which require reliable food without sockets.
• 🔄 Systems with backup power (via PoE-injector with UPS).

To connect via PoE, you will need:

1. A PoE injector (e.g., TP-Link TL-POE150S) or a PoE switch (e.g., Zyxel GS1900-8HP).
2. Cat.5e or higher network cable.
3. Splitter (if the camera does not support PoE directly)

If your camera is battery-powered (like the Xiaomi Mi Home Camera Battery) but you want to use it stationary, you can purchase a docking station for continuous charging, but keep in mind that frequent charging/discharge cycles shorten battery life.

Where to buy a power supply: official and alternative options

The best option is to buy an original power supply from Xiaomi.

• 🛒 In the official Mi Store (guarantee of authenticity, but the price is higher).
• 🌍 AliExpress (cheap, but the risk of running into a fake).
• 🏬 In large chain stores (M.Video, Svyaznoy, Citilink).

If the original block could not be found, pay attention to certified analogues from proven brands:

• Baseus - reliable power supplies with good stabilization.
• UGREEN - a wide range, including sealed models.
• Anker is a premium quality, but a high price.

⚠️ Note: When buying on AliExpress or Amazon, be sure to check reviews! Often under the guise of "original" blocks, fakes with understated characteristics are sold. Pay attention to photos of real buyers and the seller's rating (at least 98%).

If you buy a used power supply (for example, on Avito or Yula), be sure to check its performance with a multimeter. Measure the voltage at the output - it should be exactly 5V (permissible deviation ± 0.2V).

💡

Before buying a power supply on AliExpress, write the seller a message: “Is this adapter original Xiaomi? Can you provide a photo of the label?” – this will help to weed out scammers.
