The time it takes to charge a laptop for the first time mainly depends on the laptop battery capacity and the charging energy efficiency it supports. Generally speaking, with the same charging power, the larger the notebook capacitance, the longer the charging time required. Similarly, under the same capacity, the higher the charging energy efficiency supported by the notebook, the faster the charging speed, and the shorter the required charging time.
For example, the HP Zhan 66 uses a 3-cell lithium battery, while the Shadow Elf 4 uses a 4-cell lithium battery. The latter has a larger battery capacity and longer charging time. Under the same battery capacity, the Zhan 66 supports fast charging and can be charged to 90% in 90 minutes, which is shorter than the charging time of ordinary notebooks.
At the same time, the time required for the first charge of a laptop is also affected by the original power and the energy consumption of the laptop. The higher the original power, the shorter the charging time. The higher the energy consumption of a laptop, the longer it takes to charge.
