At some point in our lives, we’ve all had the annoying experience of having a low battery. Mobile devices like tablets, smartphones and even laptops are designed to make your life easier and more fun. Sometimes, you enjoy using these devices so much that you almost feel invincible; and then the fun is cut short when these devices run out of battery and there’s nowhere to charge them. Generally, this is when power packs come in.

If you search for the power packs on the internet, the keyword you probably type in the Google search bar is “power bank”. However, you may realize that the search result can be confusing. Why?

Actually, not all the power packs are designed for smartphones and tablets.  If the search results include “power bank 110v”, they mainly refer to power banks for laptops. Actually, power banks of 20V output can also power up your laptops if they are the latest models with Type-C output.

Another kind of power pack is usually called power bank jump starter and comes with “power bank 12v output”, which is to revive  cars when the car battery dies. This is very convenient since you don’t need to be stranded on the roadside for a longer time to find a kind-hearted driver who’s willing to lend you his own battery to jump start yours.

To avoid going through too many websites to get what you want exactly, it’s necessary to figure out what is the difference of the three kinds of charging packs. Here is the comparison by capacity and output voltage, which are the main difference for these  power packs.
