With the development of technology and network upgrades, more and more electronic products such as smart watches and phones seem to be inseparable from the power bank.
The ensuing problem is that people gradually find that the small-capacity power bank is not enough. Therefore, the capacity of the power bank in the market continues to rise from 5000mAh, 8000mAh, and 10000mAh. Many enterprises that saw the “business opportunity” immediately changed their guns, they changed directly from “small” to “large” on the label. The virtual standard power: the 5000mAh power bank is sold as 7500mAh, and the 15000 mAh power bank is 20000 mAh.
In the case of a power bank with a virtual capacity, the consumer will encounter a wrong estimate of the power during the use process, obviously buying 20000mAh, but charging the phone once or twice will not work, resulting in a mobile phone at a critical moment. Or digital devices have no electricity to charge.
In addition to the capacity of the virtual standard, the choice of charging battery is also very knowledgeable. The poor quality charging battery was mainly used for cottage mobile phones or assembled battery packs. The price of these batteries is relatively low. Some mobile power companies are shoddy. Even some merchants simply use metal instead of battery modules to put them into power bank. Bringing no small security risks to users.
As we know the incident occurred before, the power bank was spontaneously burned on the flight, that is, the passenger used the inferior power bank, causing a fire.
Therefore, a power bank with both large capacity and safety is definitely our first choice. So, what kind of a power bank we can choose?
First of all, the brand must be guaranteed. The big-name products are not only of good quality, but also strictly enforce national standards. They must comply with a number of rigorous tests and tests by manufacturers. Such as electrostatic discharge test, partial pressure test, static self-consumption test, charge performance test. At the same time, you should choose a regular channel to buy a power bank, reject unbranded models, no manufacturers, no electrical parameters, no warning instructions.
Secondly, the purchase of power bank should also pay attention to the internal component quality, connection methods and other aspects. High-quality charging treasure products generally use 18650 batteries or polymer batteries. The high-quality 18650 battery core has flexible combination, high internal resistance, high capacity, high voltage, high safety and long service life. The polymer battery has good safety performance, small thickness, light weight, working temperature range, cycle life and environmental performance. Therefore, consumers should carefully check the internal components and connection methods when purchasing. For the same type of products, the higher the capacity, the weight should be relatively heavy, and the inferior product weight of the internal components is relatively light.
Again, it depends on whether the output voltage/current is up to standard, stable, the conversion rate is not high, the safety protection design is in place, the cycle life is not high, the casing is strong, flame retardant, and so on.
