The 21st century is nothing but humans powered by the best available technologies and promising solutions. Without any doubt, our lives are completely dependent on electronic gadgets like smartphones and laptops. These devices have become power-efficient; however, we still need to charge them multiple times a day. It is safe to say; modern smartphones aren’t able to manage 24 hours, even with moderate uses. 

Contemplating the problem, technology furthered to building portable batteries that don’t need a socket to charge your electrical gadgets. The device was called a power bank. Known around the world for its immense usability, power banks have been in the market for quite some time. However, considering the huge customer base for such products, several manufacturers started launching their power banks in the market. The result, an overwhelming number of options for users. This made the task of buying power banks extremely difficult. 

Mostly, customers judge a product with its price, however, that is not always true. It is, therefore, important for customers to study the device to find the best one in the market. Although power banks are a plug and play product, there are still some things that you need to know about these sophisticated gadgets.

Here are some essential facts about power banks, that’ll designate you as a smart customer. 

1.) Power banks use lithium-ion batteries

Battery technology is much better than it was before. There was a time when people used older technologies like nickel-cadmium that took forever to charge and barely held any power. There were occurrences when the battery simply blasted due to faulty architecture. The only reason the accidental rates have dropped down is because of the amount of safety and research put into lithium batteries used inside the power banks. However, if you don’t use your power banks in the right manner, it can turn into a dangerous object. 

This includes instances like lying in a hot car window or being too close to a heat source. The way you handle your power bank decides its lifespan and efficiency. 

2.) Power banks capacity isn’t always what it is said 

This is a very common manufacturer practice of listing the mAh or milliampere-hours that aren’t actually consistent with the power bank’s capacity. mAh measures the total electrical charge that a battery can hold. The battery inside your laptop and smartphone is also abbreviated in the same way. 

This means, if you buy a battery of 10,000 mAh, and your phone’s battery needs 2500 mAh, then you must get 4 full cycles, right?

Well, as much as disappointed we are to tell you this, but it is not the case. You need to consider the watt-hour (Wh) and the acceptable voltage for lithium batteries, i.e., 3.7 voltage. Furthermore, you also need to take the lossless energy conversion into account. Converting the chemical energy in the power bank to electricity, and then back to chemical storage will dump some heat as waste. Make sure you buy power banks with at least 10,000 mAh or 20,000 mAh, just like the ones sold by Smartcell.

3.) The current matters too 

Smartphones and tablets charge at 2.1A. Consequently, most of the power banks have at least one port rated 2.1A or 2.4A. Even if the port offers more charge, your device will only take as much it can. Plugging in the device in such ports will only charge it at a speed like that of a wall charger. 

4.) Quality charge standards are going to make all the difference 

If you’ve recently bought a phone, you know how fast it charges when connected to a wall charger. Well, it might come as a surprise for you when your power bank takes up the entire day for charging. There are several reasons for it, therefore, it is better to keep your power bank charged for emergencies only. 

Take note of the charging standards mentioned with the power bank. Therefore, just confirm that the power bank is qualified as per the set quality standards. 

5.) You can even charge your laptops with the power banks

Some power banks support laptop charging as well. However, these larger devices accept 12V power from a supply that converts high-voltage AC coming from the wall. You can check whether your power bank supports laptop charging. 

Conclusion

The more you educate yourself with the workings of a power bank, the easier it will be for you to buy a good one. Smartcell power banks are one of the most trusted in the matter, cheaper than the top competitors, yet better in quality, mAh, and efficiency. Take note of the brand when you buy a power bank, and indulge only with the top-quality products. As for Smartcell, currently, there are 10,000 mAh or 20,000 mAh power banks available.
