As you know, fast charging is so familiar and popular on smartphones, recently this technology has begun to appear on some laptops. And soon, lassho.edu.vn will inform you about the most basic information about fast charging technology on laptops, and is there any difference compared to smartphones?
What is fast charging technology on laptops?
Fast charging is increasing the output power (W) on the charger many times to shorten the charging time. To increase capacity, manufacturers often choose to increase voltage (V), or simultaneously increase both voltage (V) and amperage (A).
Thus, fast charging is similar to drinking 1 glass of water through a straw, if using a large diameter straw, it will reduce the time compared to using a smaller straw.
A regular charger for a laptop will have an output parameter of 19.5 V, 3.34 A equivalent to 65 W, to enable fast battery charging, the manufacturer will increase the voltage (V) or increase the amperage (A). higher than the normal norm. For example, the MacBook Pro charger supports a charging capacity of up to 85 W.
How does fast charging on laptops work?
To fast charge a laptop, you need to equip a fast charger and especially the charging device must support the fast charging standard. Most laptops that support fast charging are usually equipped with a USB Type C charging port to connect to a Type C or Thunderbolt 3 laptop charging cable like MacBook Pro or Xiaomi Mi NoteBook.
Fast charging will have 2 main stages, the first stage accelerates with maximum charging capacity. However, when the battery is almost full (from 75-85% battery) the parameters will be adjusted to default to reduce the charging speed, to protect the device from overheating or damage to the battery.
Fast charging technology for laptops is still not clearly defined, each different laptop brand silently creates its own different charging standards. For example, fast charging on the HP Pavilion 15 is called fastcharge with the ability to fully charge 90% of the battery within 90 minutes (equivalent to 9 hours of use).
Does the battery with more cells charge faster?
You must have also heard when the phrase cell battery, this is the term referring to the battery capacity on the laptop. And each battery on a laptop is made up of many different battery cells.
In particular, each battery cell is a Li-ion battery with a voltage of 3.6-3.7 V and a capacity of 2,200 – 2,600mAh. When put together, they will form a complete battery. The more cells, the higher the battery capacity on the laptop.
Many people mistakenly believe that the larger the battery cell, the longer the battery life on the laptop, which is absolutely not true. Because the usage time depends on many different factors such as: screen size, processor technology, power-saving technology and especially operating performance. So it can be said that the battery cell has absolutely nothing to do with fast charging technology on laptops.
Thus, lassho.edu.vn has sent you the most basic information about fast charging technology on laptops. At the same time, also answer the question of what is a battery cell and the higher the battery cell, the faster it will charge or not? Hopefully the above information will help you more in the process of choosing to buy a laptop with fast charging technology in the future.
