Top 10 Best Power Banks

Smartphones have become part and parcel of everyone’s life. The credit for this goes to the innumerable functionalities a smartphone offers. Some of these functionalities could be online shopping, trading and managing business etc. The smartphone is powered by a battery that is lodged inside the smartphone.

Present day mobiles’ battery consumption rate is very high considering all the multiple functionalities that it needs support. A mobile’s basic functionality which is making and receiving calls tops the list of power consumption of the battery. The rate of consumption depends on whether the phone is in a low signal area or high signal area etc.

Apart from this, display of the phone, data services, and GPS etc. are the most common battery drainers in a smartphone. All these add up to the huge demand for power in smartphones. Now let’s try and understand how a power bank works and also review a bit about the multiple different types of power banks available in the market.

Types of Power banks:

Universal Power bank:  Coming supplied in different sizes and configuration, these power banks, based on our budget and purpose of use, can be tailored according to our need.

Solar charged power bank: Equipped with photovoltaic cells, solar charged power banks can charge the internal battery when exposed to sunlight. However, the downside with these is getting the batteries charged with sunlight is a long process. Hence, these power banks are also capable of getting charged via USB cable.

Battery phone case:  These devices are narrow when it comes to device compatibility as they are made device specific. As we all are already aware that Apple has bigger acceptance rate and large market in the US. Owing to the bigger acceptance rate and larger market for Apple products in the US, these battery phone cases are more common with iPhones. Battery phone cases are made exclusively fo iPhones and hence they cannot be used to recharge the batteries of other phones.

Lithium ion vs Lithium Polymer:  Power banks with Lithium-ion battery are generally cheaper and are not as efficient as Lithium Polymer when it comes to power retention.  Meaning, Lithium Polymer have slower battery discharge rate when compared to Lithium-ion. Further, the Lithium Polymer batteries get charged at a faster rate when compared to the Lithium-ion power banks.

Lithium Polymer power banks also have an increased life span providing more recharge cycles than the Lithium-ion power banks that have less number of recharge cycles.  There are the Nickel Cadmium and Nickel Metal Hydride batteries as well available in the market.  However, they suffer from ‘memory effect’.  Due to the memory effect they can hold less battery.  Hence, Lithium Polymer power bank is best power bank.

mAH: An unit of electric charge mAH is the most common way to express the capacity of batteries.  ‘milli-amp hour’ or ‘mill-ampere hour’ is the full form of mAH.  The mAH of a battery is directly proportional to the storage of battery meaning more mAH batteries will have more storage capacity.

How do I charge a power bank?

Power banks are equipped with a USB input socket and output socket.  The number of sockets may vary in some of the power banks.  Power banks can be charged by plugging in the USB cable into a laptop or directly into a wall socket. It is time-consuming to charge the power bank by plugging the USB cable into a laptop.

Charging the power bank by inserting the USB cable into a wall socket will be less time-consuming.  Nature of the battery is a deciding factor for the rate of charging, the power retention time and also the rate power discharge.  As mentioned above, Lithium Polymer batteries are extremely efficient in power retention and also have a slow power discharge rate when compared to their peers.

The total capacity of the battery is also an important factor that effects the rate at which the power bank gets completely charged.  Charging a power bank with higher capacity or mAH is usually more time consuming than charging the one with lower capacity.  As mentioned in the beginning, the power source also plays a determining role in the total time at which the power bank gets charged.

Best practices while using a power bank:

  • Charge the power bank completely before using it
  • Do not charge the power banks in the middle. Charge them only when they are completely depleted of their power
  • If the power bank is not charging even after proper connection with a smartphone or tablet, it could be because of the safety feature that is preventing to charge the device because of compatibility issue. Hence, ensure to check the safety feature before trying to recharge the device
  • Do not overcharge the power bank by leaving it for charging overnight. This may be unsafe to the consumer.  It could also damage the device
  • Do not expose the power bank to sunlight unless it is a solar chargeable power bank
  • Do not expose the power bank to exceeding temperatures

Tips for determining best power bank:

While determining the best power bank, one needs to know the various functionalities that a power bank can provide and ensure that the power bank we are going to judge is equipped with all those functionalities.

  • When it comes to longevity of power bank, Lithium Polymer power banks are unbeatable as they provide more number of recharge cycles
  • People owning more than one electronic devices for charging should go for power banks with more mAH as more mAH translates to more power the power bank can supply
  • Power bank price is but a deciding factor while purchasing power banks. The Lithium Polymer power banks are expensive when compared with Lithium-ion battery power banks. Hence, power bank price in India is also a determining factor while choosing the best power bank
  • Power banks are generally used for charging devices on the move such as outing, adventurous trips and traveling or any personal or business trips. Hence, it is advisable to purchase those that are sturdy and are wear and tear resistant
  • With the stiff competition in the power bank market, companies are adding new and innovative features to power banks such as a torch, data cable etc. Hence, consumer needs to take into account those additional features while making a purchase
  • More USB ports translate into the ability to charge multiple devices simultaneously. Hence, one needs to go with a power bank that has more number of USB ports
  • Safety features such as surge protection and high voltage protection are cardinal features that need to be taken into account while purchasing a power bank as voltage fluctuations in India are common and without these features, the device may not survive for long due to the changing voltage.
  • LED indicators is another key feature that comes handy in understanding the battery level and this feature is extremely helpful while traveling.  The reason is based on the LED indicator if the power bank is running low on power, it can be immediately charged
  • USB cables come in varied lengths and varieties. However, USB cables that are being provided by the companies such as Mi-do not get tangled.  Further, these USB cables can also be used for data transfer.  This multipurpose functionality of USB cables can be a deciding factor in purchasing the best power bank
  • Auto hibernation is another noticeable feature wherein the best power bank goes into hibernation mode once the device it is connected to is completely charged. This has dual benefits.  One is, the charge in the power bank is saved and the second benefit is over charging of the connected device is prevented.  Hence, this feature is a safety and power saving feature.
  • Last but not the least is the build quality of the power bank. Power bank made of plastic is more prone to overheating than the one that is made of a different material.  Hence, build quality also needs to be considered while buying a power bank.

All the above prove important in determining the best power bank.
