XIAOMI Mi Power Bank 2 (5000mAh): review
The portable charger XIAOMI Mi Power Bank 2 (5000 mAh) attracts the attention of the buyer at an affordable price. The cost of an electronic device is only $ 10. The device is suitable for charging any mobile equipment that requires a current of 1-2 amperes from the power supply unit and a stable 5 volts. And these are phones, tablets, portable video cameras or recorders, flashlights and other oversized gadgets.
XIAOMI Mi Power Bank 2: passions in the mobile market
The price of 10 US dollars and a small capacity of 5000 mAh, prescribes portable charging in a budget class. According to many users, the device is suitable for use with the appropriate low-price segment technology. And even sellers, succumbing to universal opinion, offer Power Bank more often to owners of inexpensive Chinese smartphones.
That's what “right advertising” means.
The essence of any portable charger is to maintain the operability of mobile equipment for a short period of time. Initially, this period of time meant the period of operation of the phone on a single battery charge (from 0 to 100%). And most manufacturers still adhere to such standards.
Given that almost all mobile equipment has a built-in battery with a capacity of less than 5000 mAh, it makes no sense to increase the performance of the charger. But the memory market does not stand still. In order to somehow move the competitor, manufacturers rushed to increase the capacity of portable devices, not forgetting to reduce the cost of products along the way.
This is not to say that chargers of large capacity are not effective and are somewhat worse. Just for the consumer, they are not effective. The following factors confirm this:
- Portable storage devices of increased power (with a capacity of more than 5000 mAh) are much larger and heavier.
- They come out more expensive in the context of prices for the final product. If we calculate the feasibility of buying every thousand mAh, then the scales are inclined in favor of devices with increased capacity.
- Well, most portable chargers of enormous capacity are made by low-grade Chinese brands. And this is an understated current and a small resource of the battery cells.

Advantages and disadvantages of the gadget
Low price, small dimensions and weight, excellent battery capacity - a list of advantages that attract customer's attention to the portable charger XIAOMI Mi Power Bank 2. Thousands of positive reviews in social networks and online stores - an excellent indicator for such a technique.
Along with the advantages, if you conduct rigorous testing, you can find a number of shortcomings. For which, because of the price, users simply turn a blind eye. First of all, the quality of the memory directly depends on the power supply, which charges the battery. Using pulse PSUs for different phones and a wattmeter, you can quickly find flaws. This is a discrepancy between charging times of up to 100% and the battery capacity in a portable device. You can also find negative reviews on a too short USB cable that comes bundled with XIAOMI Mi Power Bank 2. Plus, the ancient cable connector is micro-USB.
But overall, the portable device evokes positive emotions. In weight and dimensions, the gadget resembles a smartphone with a diagonal of 5 inches and fits perfectly in the pocket of a jacket or trousers. Due to the aluminum case, charging is not particularly heated during operation. Yes, and partially resistant to falling from a height. At a price of $ 10, it’s not worth it to demand more from the gadget.
