Low batteries are one of the greatest fears for most of us these days. Of course, in the grand scale of things, this problem might seem like a minor discomfort, but if you’ve ever been in a situation where it is crucial to have a full battery, you’d be surprised what having a recharged battery really means.

Furthermore, we’ve become so accustomed to being reachable and reaching everyone from almost any part of the world, having a recharged battery all the time is not only convenient but can also be a bare necessity of sorts. This comes as no surprise. Modern times have changed. Before mobile phones were invented, we never thought about the concept of being reachable anytime, anywhere.

With technological progress, our mindset progressed as well. Being able to reach friends and family wherever they might be has become a standard we simply live with, without really thinking about how it was before. That’s why an empty phone battery is a nightmare for most people.

Technological Progress And Phone Equipment

Luckily, technological progress didn’t stop with inventing the mobile phone. People tend to make their lives and the lives of other people easier every step of the way. That’s why today we have an ever-growing technological industry that seems to progress faster than we can comprehend. Phones become smarter and are not just used to make and receive phone calls.

The first major breakthrough in communication after the invention of the mobile phone, was, without a doubt, text messaging. This little invention echoes through the concepts of modern communication even today. Text messaging made it much more convenient to reach people in an instant manner and without getting needing to have a whole conversation.

Human language always tends to be as concise as possible, which means that text messaging (or instant messaging) is a logical step communication technology took on the way to the modern phones we have today.

The Quest For Coverage

As phones became smaller and more sophisticated, it seemed as if there were no real problems or boundaries in terms of the device we hold in our hands. The main problem lied with the mobile providers who were just discovering what it meant to offer the best possible service.

Phone batteries were still no issue. Phones were mostly still monochromatic, and their displays didn’t consume much power anyway. Furthermore, batteries were big enough to store a lot of power (the design features of mobile phones were still in the background of everyone’s mind). Functionality was important.

The best phones were those that could make the most of the scarce coverage mobile operators provided. This means that phone manufacturers gave their best to provide you with service. Hence, the antennas of older phone models. As the technology progressed, more and more features were put into phones: color displays, polyphonic music and one of the biggest inventions of that time, phone cameras.

More Features Means More Power Needed

Once people get used to their phones having cameras and color displays, the issue of battery life came up once again. Before, people were used to charging their phone’s battery in a matter of every 4-5 days. Now it seemed as if everyone had to get used to a new way of thinking when it came to charging his or her phone.

As features of mobile phones became more and more sophisticated, their power usage grew exponentially. This led to drastic changes in the industry. No one wanted to buy phones with fancy cameras displays and all kinds of other gimmicks if it meant that they had to charge their phone as many times as twice a day in some cases.

Compromises had to be made throughout the industry. However, in the end, everyone in the tech industry knew that this wasn’t enough. New batteries had to be invented in order to accompany the ever-growing power that phones consumed on a daily basis.

Better Batteries Still Need To Be Recharged

After the old types of phone batteries became extinct, it was time to find a new way to store power on a daily basis, without wearing out the battery. Lithium-ion batteries were the answer.

The old-fashioned Nickel Metal Hydride batteries, old phone models were equipped with, had one important and devastating flaw: every time they were recharged, they lost storing space, making them somewhat obsolete in the long run.

The answer was either buying a new battery pack every time the lifespan of the battery came to an end, or to live with charging your phones sometimes even several times a day.

Lithium-ion batteries didn’t have that problem. They could be recharged millions of times without losing their “spark”. Furthermore, they were much lighter than the old Nickel Metal Hydride batteries, which made them much more comfortable to wear.

This all happened in the early 2000s, which lead many manufacturers to think about not only features but also the design of the phones themselves. They saw that people like lighter phones, which made them think about other physical features they could change.

Thinner Batteries For Better Looks

Since bulky wasn’t in anymore, the batteries had to become thinner. However, they still needed to store enough power for all the features contemporary mobile phones were equipped with. When we look at the evolution of batteries, we can track the evolution of the mobile phone design as well.

Thinner batteries meant that they needed to be bigger in size. This lead to a trend of phones becoming bigger once again.

While in the early 2000s smaller phones meant that they were “better”, by the end of the decade so-called smartphones took over. Bigger displays, better cameras, and louder speakers, all of these needed a power source that could handle usage over a longer period of time.

However, there were other changes in the communication industry happening that had an influence on the phones (and batteries) we use today.

WiFi Consumes A Lot Of Power

By the end of the 2000s, the internet was being widely used. However, WiFi still wasn’t a thing as it is now. Being connected to the internet meant sitting behind your computer and looking at the display monitor. If one would say to me back then that I could have a phone in my hands and access with it the internet sitting in a cafe, I would find it hard to believe. However, 6 years later we don’t really think about the times without WiFi.

Internet was, however, just another feature costumers longed for, which meant that manufacturers had to give their best to come up with a way of making batteries last longer. WiFi receivers in our modern day smartphones consume a lot of energy. You might be aware of it yourself. The battery really drains fast when your WiFi is active and you’re surfing the web.

This brings us to today. We are aware of the battery lives of all of our devices. Today we don’t only think about mobile phones, but also about tablets, smartwatches, laptops, and even phablets (phones almost as big as smaller tablets). However, if you were to look at the small print of the batteries, you’d still find that they are Lithium-ion or the slightly newer Li-Polymer batteries.

Don’t get me wrong, batteries have become much better at handling our phone’s power consummation when compared to the first Lithium-ion batteries, it’s just that our needs have steadily grown so that batteries simply couldn’t keep up with our demands.

The Modern Era And Battery Chargers

When phone manufacturers became aware of the hard truth (that batteries simply couldn’t keep up), they made a decision to put something else on the market. So-called battery chargers were conceptualized as separate external batteries you can charge with the same charger that you charge your phone with. However, this battery would then be able to act as a power outlet you could hook your phone on and charge it when it runs out of battery.

Today, battery chargers have become a hit amongst those who travel a lot. Having a separate battery unit has become rather important in many situations. We’re not talking here just about you missing the latest episode of your favorite TV show while on the road. Battery packs can come in handy in more dangerous situations that can potentially have drastic consequences.

People who get lost in the wild, or simply need to call for help, now can think ahead when going on potentially dangerous adventures. People who depend on their devices for work and other important activities, now have a way to oppose the dread of running out of “juice” in the middle of an important phone call or presentation.

With this in mind, it becomes apparent that battery chargers or battery packs have to be not only able to recharge your device, but also to be as reliable as technologically possible. That’s why we’re going to take a look at some of the best battery chargers today and compare them.

We hope this review will help you to make an informed decision if you’re in the market for a battery charger. Furthermore, we will provide you with information about the models of phones that can be charged with the models we’re reviewing here.
