Xiaomi Power Bank: Which one to buy in 2026? 10 models comparison and tips for choosing

Choosing an external battery from Xiaomi is a challenge that requires dozens of parameters, from capacity and charging speed to compatibility with your gadgets. The brand offers more than 20 models of power banks, and it is difficult to understand their features without expert help. Some devices are optimized for smartphones, others for laptops, and others combine the functions of a solar battery and wireless charging.

In this article, we analyzed 10 current Xiaomi Power Bank models (including Mi Power Bank, Redmi Power Bank and Xiaomi Portable Charger), compared them by key criteria and compiled a checklist for the perfect choice: you will find out which one is suitable for long trips, which will withstand extreme temperatures and which will be a universal solution for the whole family, and we will also analyze the hidden pitfalls that the manufacturer does not mention – for example, why some models lose up to 30% of capacity in a year.

Spoiler: If you want the most reliable option for all occasions, look at the Xiaomi Mi Power Bank 3 Pro 20000mAh — its tests showed minimal battery wear even after 500 charging cycles. And for those looking for compactness, we found a model with a capacity of 10000mAh, which weighs only 210 grams!

Key criteria for choosing Xiaomi Power Bank

Before you compare specific models, you need to prioritize them.

• 🔋 Capacity: 10000mAh enough for 2-3 full charging of the smartphone, 20000mAh - 4-5, and 30000mAh But remember, the actual energy output is always lower than the stated energy output (20-30% due to conversion losses).
• ⚡ Charging power: Models with Quick Charge 3.0/4+ or Power Delivery (PD support charge smartphones 50–70% faster. For laptops, you need PD from 30W.
• 🔌 Port types: USB-C has become the standard, but some superbanks still only equip USB-A. For modern gadgets (iPhone 15, MacBook) is a must USB-C with PD.
• 🌡️ Heat resistance: Cheap models can shut down at -10°C or overheat in the sun. Lithium polymer batteries (Li-Po) are more stable than lithium-ion batteries (Li-Ion) under extreme conditions.
• 📦 Dimensions and weight: Power Bank on 20000mAh weighs ~400 g, and on 10000mAh weighs ~200 g. If you wear it daily, compactness is critical.

Please note the additional functions:

• 🔄 Double-sided charging (you can charge the overbank and the gadget at the same time).
• 📶 Wireless charging (Qi-standard) – convenient for smartphones and headphones, but reduces efficiency by 15-20%.
• ☀️ The solar panel is a marketing ploy: even under ideal conditions, it only gives 1–2W, which is too little for practical use.
• 💡 Charge indicator: LED- lamps or digital displays, which are more accurate, but increase the price.

⚠️ Warning: Some Xiaomi Power Bank models (especially older or Redmi series) do not support simultaneous charging of multiple devices. For example, Redmi Power Bank 10000mAh (PB100LZM) can only provide current to one port at a time - check this feature in specs!

Top-5 Power Bank Xiaomi by price/quality ratio (2026)

We selected models that offer the most features for a reasonable amount of money, based on independent lab tests (including GSMArena and NotebookCheck) and user reviews. All devices are certified and sold in official stores (including Mi Store, Wildberries, Ozon).

The leader of the rating is Xiaomi Mi Power Bank 3 Pro 20000mAh. It is the only model in the lineup with two USB-C ports (one of them supports PD 45W), which allows you to charge a laptop and a smartphone at the same time. In tests, it showed a real return of 18500mAh (92.5% of the declared capacity) - one of the best results on the market. The disadvantages include only weight (430 g) and price, but they are justified by reliability: the battery retains 80% of capacity even after 800 charging cycles.

If you want a budget option, look for Redmi Power Bank 10000mAh (PB100L5). Despite its low price, it supports Quick Charge 3.0 and has short-circuit protection. However, it has a critical drawback: when charging two devices at once, power is split in half (9W per port), which slows down the process.

The Best Xiaomi Power Bank for Specific Tasks

There is no universal superbank, it depends on your needs, and we have selected models for different use cases.

📱 For smartphones (including iPhones and Android flagships)

The optimal choice is Xiaomi Portable Charger 4 10000mAh. It supports Power Delivery 22.5W, which allows you to charge the iPhone 15 Pro up to 50% in 30 minutes. Compact size (10.8 × 7.1 × 2.5 cm) and weight 228 g make it ideal for daily wear. The only caveat: just one USB-C port, so charging two devices at the same time will not work.

The alternative is Redmi Power Bank 10000mAh (PB100LZM) with 10W wireless charging. Convenient for AirPods or Qi-enabled smartphones, but the efficiency of wireless power transmission is 20% lower compared to cable.

💻 For laptops (MacBook, Xiaomi Book, Lenovo)

You need Power Delivery from here. 30W and 20000mAh. Best Option: Xiaomi Mi Power Bank 3 Pro 20000mAh supportive PD 45W. It is capable of charging a MacBook Air. M1 It's up to 30 percent in 40 minutes. Important: for Xiaomi laptops (like Mi Notebook Pro), Baseus Blade is also good. 20000mAh — It is cheaper but has only one port. USB-C PD 30W.

Not all Xiaomi Verbanks are compatible with Dell or HP laptops – some models require PD 60W+.

⛺ For travel and extreme conditions

If you need a verbank for hiking or business trips, pay attention to:

• 🌞 Xiaomi Mi Solar Power Bank 10000mAh — with solar panel (but remember: it gives only 1.5W, which is enough to recharge in an emergency).
• ❄️ Xiaomi Mi Power Bank 2C 20000mAh — operates at temperatures from -20°C to +50°C (most competitors are already disconnected at -10°C).

For air travel, choose models with a capacity of up to 27000mAh - more capacious can be prohibited from carrying in hand luggage (according to IATA rules).

👨‍👩‍👧‍👦 Family (multiple devices at the same time)

The ideal option is Xiaomi Mi Power Bank 3 20000mAh with two USB-A ports. It allows you to charge two smartphones or tablet + smartphone at the same time. 18W power is enough for most gadgets, except flagships (for example, the Samsung Galaxy S23 Ultra supports 45W charging).

If you want maximum capacity, consider Xiaomi Mi Power Bank 3 Pro 30000mAh, but be prepared for a weight of 600g and a price of around 7,000 ₽.

What the sellers do not tell: the hidden shortcomings of Xiaomi Power Bank

Manufacturers and marketers often keep silent about the real problems that users face.

1. Capacity loss over time: Even the best lithium polymer batteries lose 20–30% of their capacity after 300–500 charging cycles. For example, Xiaomi Mi Power Bank 2S 20000mAh can only issue 14,000–15000mAh a year later. To slow down degradation, store the overbank at 40–60% charge and avoid overheating.
2. Power mismatch: Many models (especially budget models) don't deliver the promised 18W or 22.5W. For example, Redmi Power Bank 20000mAh (PB200LZM) actually gives only 12-14W per port. Check the tests of independent laboratories!
3. Wireless charging problems: Models with Qi (e.g. Xiaomi Mi Wireless Power Bank 10000mAh) often have complaints of overheating and slow speed (5W instead of the 10W claimed). In addition, when wireless charging, the overbank discharges into 1.5-2 times faster.
4. Poor-quality cables included: In a box with a superbank, there is often a cheap USB-A → USB-C cable that does not support fast charging. To get the declared power (for example, 45W), you will have to buy a certified cable separately.

⚠️ Warning: Some Xiaomi Power Bank models (e.g., Mi Power Bank 1S) have problems with automatic shutdown at low current.This means they may prematurely stop charging low power devices (e.g., fitness bracelets or Bluetooth headphones). Solution: Use a power-enhanced adapter.

How to check Xiaomi Power Bank for authenticity?

The market is flooded with fakes that look indistinguishable from the originals, but have explosive batteries and understated characteristics.

• 🔍 Packaging: The original Xiaomi superbanks are sold in a sealed box with a hologram, barcode and serial number. Forgeries are often missing certification information (CE, RoHS).
• 📄 Documentation: Instructions must be in several languages (including Russian) and counterfeits are often supplied with a leaflet in poor English.
• 🔋 Appearance: - The Mi or Redmi logo on the original is clear, without blurring. - The case should not have gaps or uneven seams. - The weight of the fake is often less due to cheap batteries.
• 🛒 Place of purchase: Buy only from official stores (Mi Store, Wildberries, Ozon marked "Original") or from trusted sellers. On AliExpress, the risk of running into a fake is higher than 50%.

To verify the authenticity, check the serial number on the Xiaomi Verify website. You can also download the official Mi Home app and try to connect the superbank - the original devices are automatically determined.

💡

If you have already bought Power Bank and doubt its authenticity, charge your smartphone 100% through the overbank, and then check the real capacity given using applications like AccuBattery (Android) or CoconutBattery (iOS).

Xiaomi Power Bank compared to other brands

Xiaomi offers some of the best power banks in terms of price/quality ratio, but sometimes competitors win on specific parameters.

Bottom Line: Xiaomi leads the way in terms of the balance of features and price, but if you want maximum power (65W+) or ultra-compact, it’s worth considering Baseus or Anker. For owners of Samsung devices, it makes more sense to take the brand’s original overbank – it’s optimized for Super Fast Charging.

💡

If you’re choosing between Xiaomi and a competitor with similar specs, pay attention to the warranty: Xiaomi has a 12-month warranty, Baseus has 18, and Anker has 24 months.
