The key to mobile power is lithium battery technology, and lithium-ion batteries were first developed by Sony in 1990. As a pioneer in lithium battery technology, Sony's mobile power supply performance is also remarkable.
The Sony power bank is not outstanding in terms of functionality, but it is outstanding in the charging and discharging capacity of the core. Sony has eliminated traditional lithium-ion battery technology with more advanced polymer lithium battery technology and has the ability to mass-produce polymer lithium batteries. Most products on the market use the lower-cost 18650 battery, which has a large power attenuation after multiple charges and discharges, and is not as safe as polymer batteries. The gelatinous polymer battery cells used by Sony can keep 90% of the chargeable and discharging power of the mobile power supply after 1,000 uses, which is better than the level of most brands of lithium polymer batteries on the market, while the mobile power supply with 18650 cells cannot even reach 1,000 cycle life.
Sony's power bank has only four products, namely CP-V10B, CP-VC10, CP-SC10, and CP-V20, priced at 239-499 yuan. The number 10 represents 10,000mAh and 20 represents 20,000mAh. Among them, CP-VC10 and CP-SC10 have Type-C ports, which can support QC and PD fast charging protocols to quickly charge mobile phones and laptops, and it only takes 5 hours to fully charge their own power.
Sony CP-V10B is mainly thin and portable, the price is 239 yuan, the capacity is 10000mAh, and the thickness is only 16mm, which is almost the thinnest among the same power products. Users can hold the mobile phone and the power bank at the same time with one hand, and play while charging, which is more suitable for daily commuting or slow-paced scenarios with little power demand.
Sony mobile power banks are all self-produced battery cells, which are more guaranteed in quality. It is suitable for people who use mobile power banks frequently, and higher security and portability are also its shining points.
