Key Guidelines for Buying a Power Bank

A power bank, also known as a "power bank", is a portable battery device that can store electrical energy and be used to charge various electronic devices. Its small size, high capacity and versatility make it a must-have in people's daily lives and travels. There are some important considerations when choosing to purchase a power bank, and below we will provide some guidelines:

1. Choose the place of purchase: It is recommended to go to shopping malls, specialty stores or trusted online stores with larger scale and better service quality. This makes it easier to find products with guaranteed quality.

2. Brand reputation: Choose mobile power products from well-known brands. These brands usually have advanced manufacturing processes and quality management systems, and product quality is more guaranteed.

3. Outer packaging and logo: Check whether the outer packaging of the mobile power supply is intact and contains basic accessories such as product qualification certificate, Chinese instruction manual and warranty. At the same time, carefully check the appearance of the product to ensure there are no cracks or burrs, no rust on the interface, and regular buttons. The product body should have standardized Chinese logos, manufacturer names or trademarks, warning instructions and other information. Avoid buying "three no's" mobile power supplies that have no Chinese information, no manufacturer information or trademarks, and no electrical parameters.

4. Safety certification: Check whether the use of restrictions on hazardous substances in electronic and electrical products is marked on the product manual or outer packaging. The relevant information should be clearly visible.

5. Charger selection: Choose a charger with CCC certification mark to charge the mobile power supply, and avoid using the "three noes" charger without CCC certification mark, no Chinese information, and no manufacturer information or trademark.

6. Charging precautions: Do not charge and discharge the power bank frequently, and avoid charging for long periods of time. When charging, pay attention to whether the outer shell temperature is abnormal to avoid damaging the internal protection circuit and causing accidents.

7. Check the status of the mobile power supply: If the mobile power supply is accidentally dropped or hit by a heavy object, please do not rush to use it. Check whether the outer casing is cracked or bulging, and whether there are any loose parts inside that are making abnormal noises. If the above situation occurs, you should stop using the mobile power supply and contact after-sales maintenance. If there is no after-sales service, it should be scrapped.

8. Storage and protection: When the mobile power supply is not in use, it is recommended to put it in a protective box or store it separately to avoid contact with metal objects to avoid short circuits. If it will not be used for a long time, it is best to retain about 80% of the power before storage, then package it and store it in a dry, cool place.

9. Check the quality certificate: If you have any questions about the product, you can ask the merchant to provide product quality certificate documents issued by the market supervision department or a third-party testing agency, such as test reports, sampling reports and certification certificates, etc., to check whether they contain the test content of the relevant products. And whether each test item is qualified. If there is a certification certificate, confirm whether it is applicable to the product model.

Buying the right power bank ensures that you always have enough power when you need to charge it to meet your daily life and travel needs.
