With the incoming winter season we all want to travel. But then for some of us travelling is part of the work process. In these times finding a portable power backup solution can be a daunting task. Whether you are a company executive on tour, a content creator/ vlogger or a leisure traveller the need for emergency power is always felt. However that need can be a thing of the past.

Recently we came across a power bank that-

  • Supports fast charging
  • Charges quickly
  • Comes with its own 65W USB C to C cable

Coolnut 20000mAh Fast Charging Power Bank 100W: in the box

Coolnut 20000mAh Fast Charging Laptop Power Bank 100W version comes in a premium packaging.

So before we took this out on a road we figured why not put it to the test with a powerhouse and actually test it mettle. Yes, of course while one will take this on a road trip you will:

  • Charge the powerbank at a power point
  • Will use it at remote places and campsites
  • Use it to charge other gadgets and batteries while on the go

Typically, the utility of the product is what you derive from it. Having said that we ran some initial tests to understand how this product worked out. Did it impress us, well read on.

Coolnut 20000mAh Fast Charging Power Bank 100W: Out of the box experience

Out of the box, the power bank came a 100% charged. Using the cable, it charged a Dell G3 15 laptop in 2 hours to about 70% of the laptop’s battery capacity. Once the power bank was fully depleted we put it to charge using the power adapter that we got from Coolnut along with it. The 20,000mah battery pack took 1.5 hours to charge a 100%. We then turned the tables and used the power bank and the in box USB C cable to charge a Lenovo ThinkPad business laptop. In one hour it charged this compact machine about 41%, going from 100% to 67% during that period.

Given its weight, compact dimensions and available ports this product goes beyond its application for individuals who are constantly on the go, the Coolnut power bank addresses most of your power backup needs.


Coolnut 20000mAh Fast Charging Power Bank 100W: Applications –

  • Auxiliary/ emergency backup for laptops
  • Power bank to not only smartphones or tablets, it can also charge portable heavy duty photography and videography equipment on the go.
