In terms of safety, as long as you are looking for a good reputation, businesses with their own brands can guarantee safety.

"If the battery capacity of the mobile phone reaches 4000 mAh, it is already very dangerous, and the risk that the manufacturer has to bear is very large." He Shijiang, general manager of Shenzhen Nosil Energy Company, said that if the 4,000 mA battery is short-circuited, the consequences will be unimaginable. Mobile phone manufacturers and battery manufacturers are well aware of this danger and generally do not take this risk.

According to reports, whether it is a brand mobile phone or a brand mobile phone, the requirements for the quality of mobile phones are very high, and the requirements for mobile phone accessories suppliers are also very strict. Generally, so-called security agreements will be signed. Once the mobile phone burns and explodes due to battery problems, the compensation amount of the mobile phone battery supplier may range from 50,000 yuan to 65,438+10,000 yuan. From a technical point of view, at the current technical level, the maximum battery capacity of a general mobile phone is only 1000 mA, and it can be increased to 1700~ 1800 mA. If the battery capacity exceeds 3000 mA, the general mobile phone battery factory can no longer produce, let alone produce 4000 mA batteries.
