Fengyang people hurry up and check themselves! Prevent explosions!
Recently, a blogger posted
I bought a 10,000 mAh power bank 6 years ago
The tail is a bit bulging
So, "After six years, do you want to change it?"
Related topics have sparked heated discussions
Some netizens reminded:
▼
"The old advice was to throw it in a special recycling place, and the power bank looked like it was going to explode. ”
"It's time to replace the power bank, and the power bank battery also has a service life. ”
Some netizens are worried:
▼
"The power bank I used hasn't swollen for ten years, but now the battery is not good. ”
"The same power bank is also deformed and cracked, and it can still be used, but it is worrying. ”
There are also netizens who analyzed:
▼
"It depends on the recycling of the power bank identification number, and there will be problems if the power bank exceeds this number. ”
Domestic first-line brand power bank manufacturers
The relevant technical personnel responded:
"On the side of the brand power bank, there is a recyclable logo, and the number in the middle represents the recyclable life of the battery in the power bank.
If the number is 5, it means that the rechargeable battery has a recyclable life of 5 years. If a rechargeable battery is a consumable and exceeds its recyclable life during frequent use, the battery may become abnormal.
In addition, there are many reasons for the bulging of the power bank, one is the aging of the battery itself, and the enriched gas accumulates to a certain extent, and the shell is lifted. The second is improper charging, which may be caused by inferior charging heads, etc., which may cause the temperature of the power bank to rise and the battery to swell. The third is the quality of the battery itself. ”

The circle is marked by the 5-year recyclable battery on the power bank.
Regarding the situation reported by netizens, the staff finally analyzed and believed:
"The power bank has been used for 6 years, which has exceeded the battery recyclable life of 5 years, and it is recommended to replace it with a new power bank.
In addition, judging from the picture, the power bank has been bulging, pay attention not to touch it with sharp objects to avoid accidents, and should be placed in a special battery recycling point. Generally, the power bank produced by regular manufacturers has a 12-month warranty period, and if it is overwarranted, it will not provide free warranty. ”
Shop for power banks
What should I pay attention to?
1. Look at the logo information
Pay attention to the information on the product identification information and product manual, and after August 1, 2024, the power bank that has not obtained the CCC certification certificate and marked with the certification mark shall not be shipped, sold, imported or used in other business activities.
2. Look at the rated capacity
In order to show the large capacity of the power bank, the business generally marks the capacity of the rechargeable battery (such as 1000mA·h) in a conspicuous place, but during normal charging, the power bank is actually unable to reach the battery capacity due to the energy loss such as voltage conversion and heating.
The rated capacity is the effective discharge capacity of the power bank determined by the manufacturer, and the higher the rated capacity, the more power the power bank can charge the mobile phone!
3. Check whether the fast charging protocol matches
The PD protocol refers to the USB-PD protocol, which is a fast charging protocol proposed by the USB-IF organization, which aims to provide high power transmission and faster charging speed. The fast charging protocol can be understood as a kind of code between the mobile phone and the power bank. If both the phone and the power bank support the PD protocol, you can charge faster.
4. Pay attention to the rated capacity when taking the plane
According to the relevant regulations of the Civil Aviation Administration, the rated capacity of the personal power bank shall not exceed 100Wh, and the rated capacity shall exceed 100Wh but not exceed 160Wh, and it can only be carried after approval by the airline.
What circumstances
Want to stop using the power bank?
