Best is a brand that only focuses on the research and development of mobile power supply, and enjoys a high reputation in the industry.

 

The battery cell is the core of the mobile power supply. The 18650 battery cells used in Best products are mainly imported Samsung/LG, which contains ternary nickel-cobalt-manganese cathode materials with high discharge efficiency, and the discharge efficiency is more than 10% higher than that of ordinary 18650 cells. Moreover, this ternary material has a higher cycle efficiency and longer life than a single lithium cobalt oxide. Therefore, the products are relatively large, small in weight, durable, and have a built-in PTC thermistor, which will automatically cut off the connection between the external current and the battery cell in case of abnormality, and the safety is more guaranteed.

 

Best also has products that use polymer cells, and its suppliers are mainly Ningde ATL, a leading domestic lithium battery company. Polymer cells are extremely safe, excellent in performance, and have twice the energy conversion rate of ordinary cells.

 

There are fewer products from Best, BST-0137DA, BST-0137DT, BST-0197 have a capacity of 10,000mAh, and BST-K6X has a capacity of 20,000mAh. Among them, 0137DA is an ordinary mobile power bank, 0137DT has added a Type-C port, 0197 is an improved model that supports digital display and comes with a folding desk lamp, and K6X is a high-end model made of polymer with high power and fast charging.

 

Among them, BST-0197, also known as Uranus, is compatible with QC3.0, supports bidirectional fast charging, and has excellent performance in basic performance. The fuselage has a built-in LCD display, which can display the power by shaking it. In addition, the product comes with a foldable LED table lamp, which is large enough to meet the normal reading in the dark, and is also the exclusive design of Best.
