Having a power bank is almost like having insurance for your electronic devices. You never know when you’ll require it, and there’s no way to predict what might happen. Your phone might die right when you’re in the middle of an important call, or your laptop might run out of battery just as you’re about to finish a project. However, if you have a power bank, those problems are easy to solve.

What is a power bank?

Power banks are portable batteries that can charge a range of devices. They’re a convenient backup charging solution for mobile devices. They can be handy when you’re away from home or the office or traveling and don’t have access to a power point.

A power bank is essentially just a battery in a box, but it needs to connect with the device it’s charging — phones, tablets, and so on — to know how much power to deliver at what voltage and so on.

Why do you need a power bank?

Power banks are essential for anyone who owns a smartphone, tablet, or any electronic gadget. The best thing about the power bank is that you can use it anytime and even when you are outdoors. This means that your phone will never run out of power no matter where you go.

Types of Power Banks

Power banks can be found in a variety of shapes and sizes, but most fall under the following categories:

Portable Battery Banks:

These portable chargers are ubiquitous and typically resemble a small brick or box. They are usually not much bigger than your smartphone and usually have one or two USB ports, charging a wide range of devices. These chargers come in various shapes, sizes, and capacities, which is how many charges they hold. They are one of the best power banks present in the market.

Solar Power Banks:

Solar power banks are like traditional power banks with the added benefit of being charged through solar energy. Because they take longer to charge than regular chargers, they should never be used as your primary charger.

Lithium-Ion (Li-Ion) Power Banks:

Lithium-Ion batteries, or Li-ion batteries, are the most popular type of power bank since they have a high energy density and are rechargeable. The Li-Ion battery can only hold a reduced charge if partially depleted before recharging.

This makes it easier to charge your phone as often as you want without having to wait for the battery to discharge entirely first. Li-ion batteries also have one of the best energy-to-weight ratios and do not contain toxic metals as some other battery types do.

You can choose the best power bank depending upon your budget and needs.

Concluding the Thoughts!

Battery technology is advancing rapidly, and so are cell phones. As such, it’s essential to be familiar with some of the various power banks offered on the market. Whether you need a portable power bank for your cell phone, tablet or laptop is up to you.
