The XIAOMI Mi Power Bank 2 (5000 mAh) portable charger attracts the buyer’s attention with an affordable price. The electronic device costs only $10. The device is suitable for charging any mobile technology that requires 1-2 Amperes and a stable 5 Volts from the power bank. This includes phones, tablets, portable camcorders or recorders, flashlights, and other non-standard gadgets.
XIAOMI Mi Power Bank 2: passions in the mobile market
The price of $10 and a modest capacity of 5000 mAh categorize this portable charger in the budget segment. According to many users, the device is suitable for use with low-cost technology. Even sellers, succumbing to the general opinion, often offer Power Banks mainly to owners of inexpensive Chinese smartphones.
This is what “proper advertising” means
The essence of any portable charger is to support the operability of mobile devices for a short period. Initially, this period was understood as the phone’s operation on a single charge (from 0 to 100%). Most manufacturers still adhere to these standards.
Considering that almost all mobile devices have built-in batteries with less than 5000 mAh capacity, there is no point in increasing the power of the charger. But the market for chargers is not standing still. To outdo competitors, manufacturers have started increasing the capacity of portable devices while reducing the cost of production.
It cannot be said that high-capacity chargers are ineffective or worse. They are just not efficient for consumers. This is confirmed by the following factors:
- High-capacity portable chargers (over 5000 mAh) are significantly larger and heavier.
- They are more expensive in terms of cost per unit. When calculating the cost-effectiveness per thousand mAh, the scales tip in favor of higher-capacity devices.
- Most high-capacity portable chargers are made by low-quality Chinese brands, which means lower current and fewer battery cell cycles.

Advantages and disadvantages of the gadget
The low price, small size and weight, excellent battery capacity are the list of advantages that attract the buyer’s attention to the XIAOMI Mi Power Bank 2 portable charger. Thousands of positive reviews on social networks and online stores are a great indicator for this type of device.
Along with the advantages, if you conduct thorough testing, you can find some drawbacks. Due to the price, users tend to overlook these. The quality of the power bank’s operation mainly depends on the power supply used to charge the battery. Using switching power supplies with different phones and a wattmeter can quickly reveal shortcomings. These include discrepancies between the charging time to 100% and the battery capacity in the portable device. Additionally, negative reviews often mention the very short USB cable included with the XIAOMI Mi Power Bank 2. Plus, the outdated micro-USB connector of the cable.
Overall, the portable device evokes positive emotions. Its weight and dimensions resemble a 5-inch smartphone and fit well in a jacket or pants pocket. Thanks to the aluminum body, the device does not heat up significantly during operation and is partially resistant to drops from height. At a price of $10, it is unreasonable to expect more from this gadget.
