People have lots of confusion when they buy power banks, how to choose?
How to avoid cheating?
Here, i will analyze how to choose
1) If it is famous brands?
Famous brands power banks usually have good quality, they have circuit protection function, more safe for using and storing; And have good packing.
But their prices are not cheap!because famous brands spend lots of cost on brand promotion and channel construction, sure, their material costs are higher. For customers, this part cost of promotion is with no value for them, so our goal is finding the right power bank or the right power bank suppliers, but not the most expensive one, or we will lose the fun of online shopping.
2) The key parts of Power Bank
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) Battery cell quality
Currently, batteries of power banks are divided into three main types: square aluminum case, 18650 type cylindrical battery, and polymer battery. Now power banks with more than 10,000 mAh capacity generally adopt 18650 batteries.
4) How to difference the PCBA board quality?
This is more difficult to distinguishing batteries. Only professional testing equipments can test out their quality. Now PCBA boards of power banks on the market are superior if their conversion rate reaches more than 80%.
5) Why have some cheap price in the market
Why there have 10000 mAh power bank sold only at 8 dollars in the market? Some undesirable businessmen adopt B products, C products, or even old batteries dismantled for the power banks.
Batteries will be divided into A, B and C products in its formal production company categories. B products used on power banks have no guarantee of capacity and service life. 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. High quality PCB boards are sold at different prices based on different sizes and components quantity. Generally PCB boards used on power banks of 10000 mAh cost 2 – 4 dollars.
JLW power bank always provide the quality but reasonable price Power Banks.
