Recently, many people involved in smart lock sales have been asking: Why can't smart lock lithium batteries use fast charging? JJR Laboratory, which has been specializing in locks for 18 years, provides a professional explanation for this confusion.
Most smart lock lithium batteries on the market have a cycle charging capacity of 250-300 times, with standard capacities of 4200mAh and 5000mAh. The charging input is typically 5V2A, with some earlier models using 5V1A.
Smart lock lithium batteries are mainly composed of two parts: the battery cell and the protection board. The current smart lock market is highly competitive, with many companies focusing on cost-cutting, resulting in the compression of costs at every step. Going back to the source, the reason why smart lock lithium batteries can't use fast charging is primarily due to cost. The battery cells used in most major smart lock brands do not support fast charging.
Therefore, it is recommended that consumers use dedicated chargers for smart lock lithium batteries or 5V2A phone chargers.
