Portable charger on the Aliexpress marketplace
Nowadays we are so accustomed to our gadgets that without them - "like without hands", especially without a phone. Often there are times when you need to go to the country house, and the battery is discharged, and it is not possible to charge it at the country house, due to the lack of electricity. Fortunately, there are Power Banks, with the help of which it is possible to "feed" your phone, navigator or other electronics anywhere, be it a bus or a summer cottage. On the website of Chinese goods "Aliexpress" such a portable device is presented at a price of 1900 rubles 94 kopecks to 2,218 rubles 16 kopecks, depending on the chosen delivery method (differs in speed) and getting into the "promotional days" with 23% discounts on the cost of the goods.
Device characteristics:
- battery capacity - 20,000 mAh 77Wh;
- battery type - lithium polymer battery;
- weight - 330.5g.
Components:
- portable battery - 1 piece;
- USB cable 1 pc.
According to the seller - 20,000 mAh is the actual capacity of the portable charger, but due to losses in the system, cables and connectors, the actual battery capacity is approximately 14,000 mAh. The device has 2 output USB ports, theoretically you can charge 2 phones or tablets at the same time, the main thing is that there is enough charging. Also included in the package is an instruction manual, but unfortunately in Chinese.
A similar portable device is presented on the Svyaznoy website, but its price is exactly 2,999 rubles, and with a promotion (which one is not specified) the price will be 2,190 rubles.
Device characteristics:
- battery capacity - 10,000 mAh;
- supply voltage - 5 V;
- the power of the string - 2 100 mA;
- weight - 207 g;
- body material - plastic.
The price on this site is about 1,000 rubles higher, and the capacity is 2 times less. But on the website of Chinese goods, they announced right away - in fact, the capacity is 6,000 mAh less, and Svyaznoy does not indicate such information, although there are "losses" of capacity in any case.
In conclusion, we can say that such a thing is necessary and very convenient to use, and if you have not yet purchased the "Energy Bank", be sure to buy it. However, it is better to buy such things in specialized stores, for example, computer centers, because the declared characteristics of Chinese manufacturers often do not coincide with reality, and even “14,000 mAh” may simply not be enough for you to charge a phone with a battery capacity of 2,000 mAh ...
