A Short Power Banks Guide

The technology advancement over the past years has seen the rise of powerful and useful gadgets such as iPods, iPhones, or tablets, just to name a few. Nonetheless, despite this very advancement, the battery life continues to be one of the major problems that many gadget users have to face on a regular basis. What’s more, this issue does not seem to be solved any time soon. However, there is one available alternative that will allow you to keep enjoying your gadgets for longer periods of time: power banks. For those of you who are not very familiar with power banks, you must know that they are special devices that are used to store power and discharge it only when necessary. Nonetheless, it is very important to keep in mind that these gadgets are available in different sizes and shapes. So, if you are interested in purchasing a printed power bank, one of the most significant factors you need to consider is whether you power bank comes with an industry certification or not. Of course there are various other factors that you need to consider before buying a power bank (for example capacity, portability, input rating, and output rating). But an industry certification is extremely important because it guarantees your safety while using your power bank.

Are industry power bank certifications really necessary?

First of all, it is very important to keep in mind that there are various electronic certification parameters and bodies. However, MSDS and UL certifications are among the most important ones as they not only guarantee safety, but also efficiency through professional testing. Having an electronic certification means that special requirements should be met during the manufacturing process and transportation of products and battery systems. Unfortunately, there are still many manufacturers who do not adhere to these requirements. This is why responsible consumers should check and make sure that the recharging gadget you intend to buy has been carefully tested and certified by accredited bodies and technology institutes. By doing so, consumers are guaranteed safety, performance, and – above all – peace of mind.

The reasons why MSDS and UL certifications are very important

Both MSDS (Material Safety Data Sheet) and UL (Underwriters Laboratories) ensure that products and battery systems have met all the national and international pre-established safety standards. At the same time, they give all the necessary information regarding potential hazards (health, reactivity, environmental and fire) and offer clear instructions on how to use the product safely. Most electrical gadgets – and power banks make no exception – can be hazardous if they are substandard or misused.


How can you check if your power bank is certified or not?

Before opting for a specific external power back-up, it is extremely important to carefully check its packaging and make sure that it features the official UL logo or UL listing Mark. Power banks are potentially dangerous battery products. And it is your duty as a distributor or consumer to avoid purchasing those products that have not been certified, regardless of how good the packaging may look like. Usually, a portable battery charger that has no UL and MSDS certification does not come with important features such as short-circuit protection, over charging protection, or temperature protection. And there is no doubt that these are among the most important features that everybody needs to consider for personal and product safety. Power bank certifications always guarantee the safety of the user. Nonetheless, this is only valid as long as the products are used according to the information provided by the manufacturer. Apart from using certified external power back-up devices, it is also advisable to opt for charging cables that are UL approved. This way, you will be avoiding problems such as melting while charging.


What can a power bank do for your smartphone?


The continuous evolution of smartphones has given birth to numerous articles that focus on teaching users how to efficiently reduce battery drainage, what phone apps drain the battery faster, and the list can go on. However, at the end of the day, it all comes down to the battery. Put simple, what bullets are to a gun, the battery is to a smart phone. Despite its small size, this device has it in its power to transform chemical energy into electric energy, thus giving our smartphones the POWER they require to meet our daily needs and expectations.

In simple words, these rechargeable batteries are a vital part of our smartphones. Without them, we would find ourselves socially impaired in a world in which connectivity makes the difference. Since it is not highly recommended to tune out those apps that make our smartphones be SMART (to save on battery), there is an alternative we can always resort to:  power banks or portable USB battery chargers. All we have to do is to choose the appropriate device for our phones and let the power of Power Banks do their magic.

There is no wonder that more and more smartphone users are quickly gravitating towards Power Banks. Power banks offer a series of important benefits: they are portable and allow users to easily charge them using the phone charger, a computer USB port, or the chargers supplemented by the device itself. Those persons who are more ecologically inclined can always opt for Solar powered Power banks, which are an environment-friendly available option.

The rechargeable battery of a Power Bank is made of Lithium ion. The capacity of a battery is measured in mAh (Milliampere-hour). Though at first sight these terms may intimidate us, we are talking about basic and simple qualities which we definitely need to understand before delving into measuring the power of portable USB chargers.

mAh (Milliampere-hour) simply means the thousandth part of an ampere hour. The Ampere is the unit of electric charge, equalling the charge which is transferred by a steady current of 1 ampere flowing for 1 hour.

Power banks store power as DC current. This is why power banks charge your smartphones much faster than AC chargers (i.e. the chargers which accompany smartphones). The reason is that AC chargers convert AC current to DC, the flow of current not being steady. As a consequence, AC chargers take longer to charge a smartphone than a power bank. Power banks charge phones with their DC output and, due to the steady flow, they charge devices more efficiently and faster.

It is also important to opt for power banks which come with Electric Circuit Protection (this will protect phones from overcharge,) Over-Discharge, Over-Current, and Short-Circuit protection. The electric circuit protection will cut off the power supply when your phone is fully charged.

What to look for in a quality power bank


Below you can find a list of the main features you should pay attention to before buying a power bank:

mAh capacity (milliamp hours)

There is no doubt that the greater the capacity of your power bank, the better service it will provide and the longer will be the internet/talk time offered by it. Nonetheless, keep in mind that a higher capacity might also mean that the power bank will be thicker and heavier. And probably more expensive as well.


A battery pack should have a convenient size, especially since you are going to carry it around with you. If your power bank is too large, it is going to take up lots of space in your carrying case or bag. Large power banks usually have a very big capacity, even sufficient to power a laptop.


Most people have multiple gadgets that need to be recharged. If that is your case as well, then it is advisable to opt for an external battery compatible with a wider variety of devices. Make sure to check this before buying it or you might end up buying more than one single external battery. It is not a bad idea to opt for a device that can charge multiple devices at the same time.


This is an important factor to consider, especially since your smartphone might have already costed you a significant amount of money. Keeping the additional expenses under control might be something you need to consider.


Last, but not least, a nice looking power bank might add to your overall style and look.

The right power pack or power bank can help you make the most of your smartphone, tablet, or other digital gadgets. This is why it is really important to do a thorough comparison of the available external battery packs and choose the one that best suits your needs and budget.

If you manage to choose the right power bank, you will enjoy your smartphone and you will never again be powerless.
