To the right. Generally, the two charging ports will be marked 2.0A or 1A, and the use of 2A's jack is faster to charge. A is the basic unit of current, 1A=1000mA, 1mA=1000.
Select the power button as the first port next to the starting point to charge the phone. Because the two charging ports have a very clear difference, the first lightning symbol represents 1A, and the second lightning symbol represents 2.1A. The mobile phone has two ports with the current of 1A and 2.1A respectively, usually the 1A output port is to charge the mobile phone, and the 2.1A port is to charge the tablet computer.
Charging bank use precautions
When choosing a charging treasure, it is necessary to choose a good quality, a regular manufacturer's production, the quality is guaranteed, otherwise there will be an explosion or other accidents during the charging process, this is not cheap, buy some charging treasure without a safety guarantee.
When the charging bank is not used, it should be placed in a ventilated and dry place to avoid short-circuit contact with metal materials, especially when putting pockets and bags, pay attention to small metal items entering the USB output, resulting in short circuit of the mobile power supply
1 USB-C port charges the fastest.
The 2 USB-C charging port has a higher power delivery capacity, allowing the charger to deliver higher current and higher voltage, which makes charging faster.
3 In addition, the USB-C charging port is also more intelligent, and the charging power can be automatically adjusted according to the charging state of the device, achieving a faster and safer charging experience. Therefore, if you want to quickly fill your phone or other mobile device, choosing a power bank with a USB-C charging port is a good choice.
There are three scenarios
The first and third exits are the same
The three outputs are connected in parallel, so theoretically the power is the same. Over time, the degree of aging is different, there will be some differences. The 1A and 2A engraved on the exterior are purely customary and look more upscale.
Two, flash charging bank
One of the three output outlets is dedicated to flash charging, and the plastic parts of the jack are different colors. The other two are generally the same, but some have a Type-C jack.
Three, three outputs really according to the identification of 1A, 2A difference
This is a more traditional and expensive design, which is rarely seen today. The use of 1A jack is more power-saving, and there is a limited current guarantee for some special electrical appliances.
Look carefully at the fast charge line, this is the fastest
The three charging ports of the charging bank, if only one is the fastest, if two are charged at the same time, the charging speed will be slowed down due to the diversion
