The difference between charging treasure 1a and 2a is 1. The appearance of 2A is obviously larger than that of 1A;
2. Then there is the charging speed. Theoretically, the charging time of 2 A can be shortened by half compared with1a. However, if the battery capacity is small, it is easy to damage the battery or shorten its life by using 2A charger. Generally, the charging current of lithium battery should not exceed 0.5C.
Suggestions on charging treasure purchase 1. Buy brand-new lithium polymer batteries and high-quality imported lithium-ion (18650) batteries to manufacture high-credibility brand mobile power supply. 2. The bigger the capacity, the bigger the volume. For friends who have a lot of digital products, often go out and have a great demand for electricity, they can choose a power supply around 10000 mA, and the power supply above 10000 mA is relatively poor in portability; For friends who don't go out often and have high requirements for beauty and portability, it is recommended to buy a power supply of 3000-8000 mA. It is very necessary to choose an exquisite and beautiful power supply. Exquisite appearance is usually a barometer of power supply material and quality. Suggested method for judging the quality of charging treasure: 1. In the same environment, charging the same amount of electricity (for example, from 50% to 100%), the charging treasure with short power consumption time is better than the charging treasure with long power consumption time. 2. In the same environment, charging the same amount of electricity (for example, from 50% to 100%), the charging treasure with high shell temperature has poor quality.

How to prolong the service life of the mobile power supply First of all, please don't put the mobile power supply and mobile phone charging treasure in the bag to charge the mobile phone, because the bag is sealed and ventilated, and the heat dissipation is extremely poor, which will lead to the heating of the mobile power charging treasure and mobile phone, reduce the service life of the mobile power supply and mobile phone, and may also lead to the damage of the mobile power charging treasure and mobile phone. It is recommended to charge the plate in a ventilated place or in an air-conditioned environment.
Secondly, there are two ways to charge the mobile power supply. One is plugged into the USB port of the computer, and the other is plugged into the household power supply. When charging the household power supply, please don't plug it into the wall socket, because the length of the adapter cable of the mobile power supply is limited (hanging charging will lead to the failure of the mobile power supply). It is suggested that the mobile power supply should be placed flat and plugged into the socket of the multi-function wiring board for charging.
Several methods to prolong the life of lithium battery;
1, there is no need to charge the power supply to 100% full charge, let alone run out of power. If the situation permits, try to keep the battery close to half full, and the smaller the charging and discharging range, the better;
2. Generally, the factory design of Chevrolet Volt electric vehicle is to force the battery charge to be maintained at 20% to 80%, and the built-in battery of Apple notebook computer may also adopt this method (including some other notebook computers and electronic products) to increase the number of charge and discharge cycles of the battery.
3. Do not operate lithium batteries (especially notebook lithium batteries) for a long time when the equipment has an external power supply. Even if your notebook has good heat dissipation, long-term 100% power is equivalent to the murder of lithium batteries.
