Comprehensive Analysis of Power Bank to Keep Away from Cheating

A lot of people have a lot of confusion when they buy power banks. Thus, I'm here to analyze how to choose a good mobile power.

1. Are power banks of famous brands the best?

Famous brands power banks have no problems on the security issue, and their quality are also guaranteed. But their prices are relatively higher, generally costing hundreds of money. If you shop online, they will be cheaper, but there are still some expensive, and why? Famous brands spend a lot on brand promotion and channel construction, and of course, this part of costs is added to the price. For consumers, this part of costs for is of no value. So our goal is finding the right power bank or the right power bank manufacturer, but not the most expensive one, or we will lose the fun of online shopping.

The most important parts of power bank are two parts: battery cells and the PCB board. Battery cells are batteries, and PCB board is the part managing the batteries charging and discharging. Many popular international brands sell high quality batteries, such as Sanyo, Samsung, Panasonic, and etc.

3. How do you know whether the batteries are good or not?

C products cannot be used absolutely, or serious accidents will occur. B battery cells only cost one-third of A products price, and C products are sold by weight as complete waste products. That is why some people can sell power bank at such low prices. As to PCB board, imported electronic components cost about 3 dollars. Also some manufacturers dismantle components on old electronic products down and reassemble again so that the prices are much cheaper.
