The cell is the core component of the power bank supply. It plays a vital role in the safety, service life and fast charging performance of power bank supply. So, what are the more well-known power bank battery brands? In the face of many power bank battery brands, how should brand owners choose? This article with this question, come to understand it!
Before understanding the battery brand, we first understand the key parameters of the power bank battery.
1 Key parameters of power bank supply cell
Energy density (Wh/kg): The larger the energy density, the smaller the volume and the lighter the weight at the same capacity.
Cycle life (times): the complete charge and discharge times of the battery. The greater the cycle life, the longer the service life of the power bank supply, and the longer the power consumption is not much reduced.
Discharge rate (C): The greater the discharge rate, the greater the potential to support fast charging. High-power fast charging requires the support of high-rate batteries, which is very important.
Safety: Safety performance usually means that the battery can pass overcharge, overdischarge, high and low temperature, drop, impact, acupuncture test and other test items, and meet the certification requirements of the target market.

3 power bank battery brand selection considerations
There are many details that need to be paid attention to in the selection of power bank battery suppliers. In addition to reviewing the size of the supplier, the overall qualification and the quality of the battery, the following aspects are also important to consider:
3.1 Don ‘t over-press the cost of the battery. Pursuing the lowest quotation may encounter risks such as second-hand batteries and B-product batteries;
3.2 Priority selection of high-profile, strong comprehensive strength of the battery brand. Reasonable choice combined with the market positioning of the product;
3.3 Identify the situation of capacity virtual scale and energy density exaggeration. This will lead to security risks and poor user experience, and will affect brand reputation. It is necessary to allow suppliers to provide standard rate discharge test reports;
3.4 Lack of certification experience will delay the progress of the project. It will also increase the hidden cost, delay product listing and other issues!
Although power bank products are mature, there are many details in R&D, testing, production and inspection. Cell selection is the key link. As a power bank source factory with more than 20 years of experience, Joway has established a long-term and stable cooperative relationship with many well-known cell brands.
