Xiaomi backpacks: how many liters in different models and how to choose the right volume

Xiaomi backpacks have long since ceased to be just an accessory — they have become a symbol of practicality and modern design. But when choosing, many people are faced with the main question: "How many liters in a Xiaomi backpack?" The answer depends not only on the model, but also on your tasks. Tourist, student, office employee or traveler — everyone needs their own volume.

In this article, we'll take a look at all the current models (2022-2026), compare their actual capacity to the declared capacity, tell you how to fit the right size for specific needs, and even check how many things fit into popular options, and also reveal secrets that the manufacturer does not always specify in the characteristics.

Spoiler: litre volume is not the only criterion, ergonomics, material, mounting system are important, but we start with numbers and facts.

Official data: the volume of backpacks Xiaomi by model

Xiaomi has launched backpacks under several brands: Mi, Xiaomi Youpin, 90FUN and ZMI, each with its own range of different volumes. Below is the current table for 2026 with verified data:

Note that many models have a volume range (e.g., 20 to 24 liters), which is due to the possibility of expanding with lightning or additional pockets. For example, the Mi Business Backpack 2 is a standard 20 liters, but if you unbutton the side zippers, the volume increases to 24 liters.

An important nuance: Chinese manufacturers sometimes round up the numbers, so a backpack for "20 liters" in fact can be 18-19 liters.

Real tests: how many things fit in Xiaomi backpacks

The numbers on paper are good, but how does the backpack work? We tested three popular models to show their real capacity.

1. Xiaomi Mi Business Backpack 2 (20–24 L):

And then there's room for small things in your pockets, and if you unbutton the side zippers, you add space for an umbrella or a small bag of food.

2. 90FUN Travel Backpack Pro (30–35 L):

This backpack replaces hand luggage in the plane - tested in practice with airlines S7 and Aeroflot. the main thing is to distribute the weight correctly so as not to exceed the norm by weight (usually 5-10 kg).

3. Xiaomi Youpin Lightweight Backpack (18–20 L)

This is an option for minimalists. If you need to take more, you better look towards the Mi Business Backpack.

💡

To check the actual volume of the backpack, fill it with packets of rice (1 liter = 1 kg of rice) so you will see how honest the claimed liters are.

How to choose the volume of Xiaomi backpack for your tasks

The size of the bag depends on where and how often you pick up the backpack, and here's a checklist to determine the ideal size:

Volume recommendations:

• 🎒 10-15 liters: for short trips, walks, gym. Examples: Xiaomi Mi Sports Backpack, Youpin Mini Backpack.
• 💼 15-25 liters: universal option for the city, study, office.
• ✈️ 25-35 liters: for travel, hiking, long business trips: 90FUN Travel, ZMI Classic.
• 🏕️ 35+ For serious tourism or changing bags at the airport, Xiaomi has few of these models, but there are many. 90FUN Hiking Backpack at 40l.

⚠️ Note: If you take a backpack under your laptop, check not only the volume, but also the size of the compartment! For example, Mi Business Backpack 2 fits a laptop up to 15.6, and Youpin Lightweight only up to 13".

Another thing is ergonomics. A 30 liter backpack might look huge, but if it has narrow straps or no belt, it's not comfortable to wear it. Xiaomi has a nice order of things, and almost all models have soft straps with a gasket and back ventilation.

Secrets that don’t write in the characters

Manufacturers often keep silent about the nuances that affect comfort. We have collected 5 hidden facts about Xiaomi backpacks:

1. Water-repellent ≠ Most models have a rain-proof coating, but they won't withstand the dives — 90FUN Waterproof Backpack (up to 5000 mm water column).
2. USB-The port is not always useful. ZMI some 90FUN There's a charging outlet, but you have to buy the powerbank separately, and the wire often gets in the way.
3. Expandable volume is not always a plus, for example, in Mi Business Backpack 2, as the maximum expansion of the center of gravity shifts, and the backpack begins to hang.
4. Color affects the visibility of dirt: Gray and black models (Classic Black) are less visually dirty, and white (Pure White) require frequent cleaning.
5. Not all lightning is equally reliable. In low-end models (like the Youpin Lightweight), lightning can catch after a year of use. In premium ones (ZMI), metal ones, with a 5-year warranty.

⚠️ WARNING: If you buy a backpack on AliExpress or in unofficial stores, be prepared for fakes. Xiaomi's original models have: Logo with a metal patch (not a sticker!), Suture label with a serial number inside. The smell of quality polyester (fakes often smell like chemistry).

Comparison with competitors: who offers more liters for the same money

Xiaomi backpacks are known for their price/quality ratio, but let’s see how they compete with other brands in terms of volume.

The bottom line: Xiaomi wins in price and functionality, but loses to premium brands in durability. If you need a backpack for 1-2 years, Xiaomi is a great choice. If 5+ years, it is better than Samsonite or Deuter.

💡

Xiaomi backpacks are ideal for those who value the balance between price, volume and modern design, but if you want maximum strength or specialized features (for example, for mountaineering), it is worth considering other brands.
