Five suggestions for choosing a mobile power bank

With the popularity of smartphones and tablets, batteries are no longer able to keep up with the times, so high-capacity mobile power banks are widely favored by mobile phone experts and business travelers. However, the mobile power market currently lacks unified industry standards. Many products on the market have defects such as poor battery quality, false capacity, shortened life, and insufficient safety. In serious cases, they may even explode, threatening consumers' interests and personal safety. So, how should we choose a mobile power product with safety guarantees? You can refer to the following 5 suggestions:

1. Never choose a copycat power supply product that has no brand and no manufacturer address.

2. Pay attention to what kind of battery cells the product uses. If it uses batteries from brands such as ATL, Sony, and BYD, you can buy it with confidence.

3. Don’t pursue high battery capacity too much. The higher the battery capacity, the harder it is to control the stability inside the battery. Generally speaking, a 3000mAh power bank with no false labeling can fully charge a mobile phone twice.

4. Understand the efficiency conversion rate of the mobile power bank. If the efficiency conversion rate of the battery is less than 80%, it means that the mobile power bank circuit is damaged, the battery cell itself generates a lot of heat, and there are safety risks.

5. UL of the United States is one of the most authoritative safety certification organizations in the world. If a mobile power product is certified by this organization, you can buy it with confidence.
