This act as a supplement in case of external connection cable not available.

5. Power Bank Device Charging


There are some people who presume that having power bank is enough for charging of all devices, but this is a wrong conception. For example, if you have a laptop and you have purchased a battery bank of medium capacity, then it would not be possible for you to charge the laptop with it.

Everyone is looking for a durable and compact power bank before buying a power bank. The longevity is contributed by the materials used to make it. Lightweight gadgets are more durable due to their portability nature. As far as durability is concerned, the hardness of the material comes into play. Sturdy casing prevents damages in case of accidental fall.

Most of the problems that affect power banks emanate from the daily activities that we engage in. Regular falls cause short charging destroying the internal components. If the outer material is resistive, the internal elements are protected.

9. Power Bank Power Saving

13. Quick Charge


Quick charging batteries are becoming extremely popular. This has been attributed to the need to hearken the speed of charging. The high charging power banks range between 2-3 Amperes. The demand is based on the nature of the gadget one is using. More sophisticated smartphone with high demand for power is invented at a rapid rate.

The bank with an output of 3A unbelievably charges very fast. It is a perfect choice one can settle for. However, if your phone does not demand such a high output, then 2A is good for you. The higher the output, the higher the cost.

14. Power Bank Battery


If you have multiple big and small devices then you need to make sure that you buy a power bank that will allow you to support charging all of them. You will need to select the power pack with big energy capacity to get the necessary charging of all devices.

Power banks vary in size and shapes. The major idea behind this factor is portability. You need to understand the reason you want to go for buying a power bank. Very large sizes discourage one to carry them. Settling for small sizes, which can be carried around is a good choice. Typically, hand-held size is mostly sought by the buyers.

16. USB Port


The current power bank output is crucial. In most cases, the input is not equal to the output. The running current is the one which determines how fast your gadget charges. Buyers mostly ignore this before buying a power bank.  A lot of focus is directed to capacity rather than giving the same attention to output. At least2.1A is recommended. Settling for higher amperage is allowed. You have heard complaints from the people concerning slow charging when using a power bank. The problem is primarily in the output rate.

Charging multiple devices at the same time is good stuff. One could be having one or more devices to charge simultaneously. For spouses who want to save on cost, the number of ports in a power bank is a strong factor. Two or three ports are sufficient for a single bank. It beats logic when the power bank has only one port. This is the generation where even the phone manufacturers appreciate duo sim card gadgets.

Types of Power Bank


It is comparable to a professional without the right tools of a trade. Technically, the surety of longevity of the charge in a smartphone helps an individual to reduce anxiety. Thankful to the introduction of portable batteries. Well, before you go buying a Power Bank, it is crucial to know the type that you are keen to buy.

Lots of Other Types of Power Bank

There are two base types of power banks. Ones that have high power capacities and ones that have low power capacities. They both hold a strong place with the customer because they each have traits that make them very powerful to use.

1. Small Power banks


Power banks that are small are the ones that are bought and used the most. The reason for that is because they have low power capacities, which means fewer batteries are used, as well as smaller ones. As a result, the power bank is smaller. These are so small that these power banks can fit into your pocket.

With that said, the flaw that they do have is that most are really only able to charge most smartphones at least once or twice before they need to be recharged.

2. Large Power banks


I may be using the word “Large” just a little too freely, but there are power banks that are certainly bigger than Mini power banks. The reason for that is because these have high power capacities, so they have more batteries and larger ones. Not exactly the best to fit into your pocket and they also have heavier weights.

On the bright, power banks that have high power capacities are able to charge smartphones and other devices to their full power many times over. The great thing about having a high power capacity is also that they have many charging ports so that you can charge multiple devices at once.

Lots of Other Types


There are many different types of power banks on the market, and each of them holds their place with people that are looking for certain attributes.

3. Built-in Cables


There are power banks that have built-in cables, and these are the ones that are the most reliable. That’s because there can be times when you forget to bring your charging cable with you when you’re headed out with your power bank. If that happens, then that renders your power bank useless. So not only do these types of power banks have a single built-in cable, but they also have multiple built-in cables that are able to charge your devices if you choose to get one of those.

Built-in Cables for Powrbank

Some even have USB ports to use with any charging cable, as well as built-in methods to recharge the power bank, such as an AC Adapter or a USB cable.

4. Rugged


These types of power banks are very tough; they’re able to withstand things that are able to damage just any normal power bank. That’s because Rugged power banks have reinforcements that can take fall onto the hard ground. They’re also waterproof when their charging ports covers are covering their ports. With that said, just because a Rugged power bank is labeled as “waterproof” does not mean that it’s fully waterproof against everything. Since there are different Enclosure levels that are able to withstand different exposures of water.

Charging, Ports and Special Charging Tech


Power banks that make use of multiple charging ports are great to use. However, many people forget to take a closer look at the charging speeds of each of the ports. The reason for that is because there are power banks that have many charging ports, and yet each of the ports is only capable of charging at 1 Amp speeds.

Charging, Ports and Special Charging Tech on Power Bank

When a power bank has many USB charging ports, then it’s vital that you know what each of the ports is Outputting. So you can charge each of the devices at a good charging speed and have them charge to full promptly. For power banks that have 2-4 ports, each of the ports should at least be able to Output 5V/2.0A or higher since most smartphones and other devices have their max charging speed at or at least close to there.

There’s also special charging tech that you have to take into account while buying a power bank because many smartphones now use Quick Charge and USB-C for charging.

Know the Max Output


The Max Output is just as important as the individual charging speed that each port has. The reason for that is because you want to use each of the ports near or at their full potential. If a power bank has 3 USB ports and each port is able to Output a charging speed of 5V/2.0, and the Max Output is 6 Amps, then that is a good output.

Know the Max Output of your power bank

That’s because you’re able to charge three devices and still use the max power of each of the ports that those devices are charging from.

Input is Just as Important as the Output


The input means the recharging part of the power bank. Most Mini power banks have slow recharging speeds, and it makes sense because they have smaller capacities to recover. However, when it comes to high capacity power banks, the Input charging speed matters a lot. Since a power bank can have a 20,000mAh+ power capacity and yet it has a single Input with a speed of 1 Amp. That is going to take a LONG time to recharge to its full power.

2 Amp recharging speeds and beyond are the best. Some power banks even use two Input ports, and that makes them able to recharge at double the speed. Then there are ones that use special charging tech like Quick Charge or USB-C to recharge, and those are faster options for recharging.

Lots and lots of Brands


There are lots of brands of power banks on the market since many companies know that power banks are popular products, there are lots of them selling. It’s a good and bad thing. There are quite a few companies that are actually innovating with their products and are offering the latest tech. Then some companies still sell power banks that are very outdated.

Lots and lots of Power Bank Brands

That is why it’s vital to purchase power banks from reputable sellers that know their product and have a proven track record of selling great products. One of the most notable ways to tell this is by checking their warranty and see how long it’s for and what it entails.

Final Thoughts


The power bank is one of the major inventions in the present time. It is an impressive move in the era of the smartphone. Most people have appreciated portable batteries which save them the trouble of moving around with uncharged phones. Who doesn’t like using a smartphone? Irrespective of the quality of the phone, low battery is a nuisance to the user.

These are aspects which can be employed before buying a power bank. Take care not to be ripped off by insensitive sellers. Take every detail into consideration to save on cost. Your money should go where efficiency is guaranteed.
