The power bank is mainly composed of battery cells and PCB circuit boards. The battery cells determine the capacity; the PCB circuit boards play a management control function. As long as it is not a counterfeit or three-no power bank, it is completely fine if the brand is marked with charging and charging.
The IC (chip) used in many mobile power products is of good quality, and the control IC has a built-in high-precision voltage detection circuit and a multi-level current detection circuit. There is no need to worry too much about the safety of the power bank with its own charging and discharging function. Most of them have overcharge, overdischarge, and short circuit protection circuits. It comes with a charging cable and supports charging and discharging power banks, which can improve efficiency for users and is convenient and practical.
1. The main component of the bai inside the power bank is the battery. The quality of the battery is good or the battery is bad. If the inferior battery is discharged while charging, it will be dangerous if it takes a long time, such as Lutu and anchor The batteries used in the brand's products are high-quality batteries and well-known foreign brand batteries, such as LG, Panasonic, etc., to ensure the quality of the batteries.
2. The lithium battery is equipped with a protection board, and the step-down circuit is fully self-powered, and the electrical appliances will no longer work if the voltage is below 2.7V, ensuring safety.
3. With temperature control circuit, the lithium battery will automatically cut off power when overheated, which plays a protective role.
4. The ICs (chips) used by the big brands of mobile power products are of good quality, and the control IC has built-in high-precision voltage detection circuits and multi-level current detection circuits. Built-in charging and discharging function, with overcharge, overdischarge and short circuit protection circuit.
5. Charging and discharging are also related to the charging adapter. Using a high-quality adapter for charging is also conducive to normal operation while charging.
