What is a Power Bank?

Let’s firstly understand the mechanism of a power bank. A power bank is a simple lithium battery-laden device with a bare OS system that transfers its juice to the laptop. Upon complete drainage, we will have to charge the power bank too. This way, the circle goes on and on until the battery of the power bank completes its lifetime, mainly 1000+ charge cycles for Lithium Polymer batteries. 

Is it a pertinent idea to charge a Laptop with a Portable Power Bank?

Yes! Why not. It’s perhaps the best idea to prevent your laptop from nodding off during work. Nonetheless, we must opt-in for quality brands. A cheap but faulty power bank may ring the death knell for the laptop.

Things you must notice before buying a power bank for the laptop.

Before striking the power bank deal, we should make sure of a big tick on the following points.

  1. Battery recharge timing: As laptops have spacious batteries than cell phones, so in the same way, the power banks must have shorter battery recharge timing to keep our power banks ready to meet any untoward situation. 
  2. Airline compatible: We need to travel domestically or internationally by air, and just like the laptop, our power bank should also be airworthy; we mean TSA compliant. Otherwise, your investment would be rotting on the terminals.
  3. Capacity: More technically, we could call it the mAh or only the juice. More the mAh, more the strength of your power bank, and ultimately good milage. For better results, we must select the power option of a minimum of 20,000 mAh.
  4. USB ports: Another critical aspect of the laptop power banks is the inclusion of USB ports. Professional brands incorporate Type-A, C, and USB ports by default.
