They are charged from the normal USB sources like USB chargers or cords, as it is fully charged, there is indication on the power bank to show the state of charge..

Now, we are sure that you are all already thinking about buying the best power bank, however before you go further, make sure you take care of these factors before you make the buying decision. 

Factors to consider before buying the best power bank, include:

Capacity

The most important thing to remember is that the capacity of a power bank should always be more than the capacity your phone requires. For example, a 2400 mAh capacity will not be able to fully charge a phone with a requirement of 3200 mAh capacity, a power bank with 6000 mAh would be able to charge the phone fully.  

Ask the following questions to yourself before going forward with this:

  • How often would you like to charge your electronic devices without charging your power bank? – this will tell the capacity required. 
  • For what device you are going to use your power bank? – This is important because obviously a laptop needs more power than a smartphone. 

Pro tip: Keep in mind the mAh of the device you want to charge. The mAh of the Power bank should be higher than that of your phone or device you use. To know the same of your phone, do the following – 

Go to the settings options -> About Phone -> Battery information.

Under this option, there’s the capacity of the device that is measured in milliamp hours (mAh). 

The Number Of Outputs

The power banks of these days are so advanced that you don’t need to make a preference for this query. Do you operate your tablet and smartphone concurrently and extensively? Some power banks have 1 output outlet; some have 2, and so forth. Choosing one relies upon how many gadgets you will need to charge at the same time. You will discover a variety of power banks with five USB ports available inside the market. These power banks not only offer excellent multi-charging alternatives but also can be used as a charging hub for a couple of digital gadgets.

Size

While travelling, we have discovered that there are a few people who choose to keep their cell phones in their hand no matter how crowded it is. Whereas, there are a few who additionally opt to maintain their devices in their pockets even when traveling. What category do you fall in? In both cases, choosing something weighing approximately around 86 to 92 grams is a good choice. The size consideration is essential as you need to take the power bank with you. A power bank of your smartphone or tablet is capable for your pocket but a larger laptop power bank isn’t. A laptop electricity bank does match your backpack or handbag. They weigh around 300-500 grams and will be a great choice as it could be effortlessly carried around in the bag without being stressed.

Ampère or speed of charging

Besides the capacity of the power bank, another important thing is the amperage. It tells you how fast the power bank will charge your electronic devices. Higher the current (amp) the device charges rapidly. Many economic power banks come with a charging speed of 1 Amp. If your portable power bank has 1 Amp charging current then you are likely to experience a fairly slow charging process. Whereas, in case of dual or multi-port banks you may find each port carrying different amperage. With advanced technology, there are several power banks with rapid charging facilities, however not every phone can support the full power of a rapid charger. Therefore, it is absolutely essential to check if your phone supports quick charging technology or not and decide the pick for power bank. 

Now that you have a list of factors to see before you head out to pick the right power, prepare a quick checklist for your purchase because we are listing the top 10 power banks that you must check to finalise your buying decision.
