Smartphones have transformed our lives. They have become so important that some of us cannot even imagine our life without them. From talking and texting to checking social accounts and playing games, we using smartphones to do multiple tasks. The constantly running OS and performing all these actions quickly drains the smartphone’s battery, often restricting its on-the-go use. Earlier people often used to keep a secondary battery to combat the problem of draining battery, but now with a majority of smartphones don’t feature a removable battery, buying extra mobile batteries is not a feasible solution. Also, keeping the phone plugged into charging point all the time is not possible. Over the last few years, power banks have emerged as an excellent alternative to keep the mobiles charged even on-the-go. With the market brimming with plethora of options,
buying a mobile power bank can be overwhelming. To help you make a smart choice, we have prepared this comprehensive buying guide for mobile power bank.
Value Capacity Over Portability
The capacity of the power bank is the defining factor of your purchase. Its capacity is measured in milliampere-hour (mAh), similar to mobile’s battery capacity. This means, if your smartphone features a 2600 mAh battery, you require a 2600 mAh power bank to charge your mobile completely once. That said, factors such as power loss during voltage conversion and circuit resistance means that the power bank of same capacity as the mobile battery’s capacity is unable to charge the mobile completely. So, you need to buy a power bank with a higher capacity. It is recommended that the power bank’s capacity should at least be twice your phone’s battery capacity, so that you can charge your smartphone multiple times. Although bigger capacity means bigger and heavier power bank, your focus must be on the capacity and not weight and size.
Know Your Phone’s Input Current
Most smartphones support charging at 1A over the USB port, however, if the phone accepts a higher current, the users start to feel that the smartphone is taking time to charge. Recent crop of smartphones feature charging interface in the range of 1.5 to 2.0A. Using a power bank that outputs less power may result in slow charging, while using a higher-powered port to charge the smartphone can lead to faster charging without hampering its battery for it draws only the required amount of current.
Check Power Bank’s Input Current
Going by the earlier point and the benefits on offer, it is easy to get attracted to large-capacity power banks but remember that higher the capacity the longer it will take to charge the power bank. You may, for instance, have to leave the power bank on charging overnight. The power bank’s input current to affects its charging ability. Many power banks have input current range of 0.8A to 1.5A. If you find two power banks worth considering, their input current range can be a deciding factor.
Notice the Number of Ports
Number of charging ports too play a crucial role in selection of power bank. High-capacity power banks usually have more than one charging ports. Having additional ports comes in handy for it allows you to charge more mobiles simultaneously. When buying multiple port power banks, note the output current of its ports. A power bank with a 2A output current port may deliver 2A only when single port is in use but may limit the total output to 3A when both the ports are used for charging, limiting each port’s capacity to 1.5A. That said, you may find power banks with total output of 4A for faster charging, but it will come at a price. The number of ports also affects the cost of the power bank, so make sure you choose it wisely.
Don’t Compromise on Quality for Price
You will find a plethora of power banks listed on leading electronic stores. Their inventory is filled with both local and banded products. While the local power bank may be available at lesser price, there’s doubt surrounding their quality and performance. The branded power banks, on the other hand, will be a little pricier but offer a more reliable and lasting performance. Also, branded power banks have advanced features such as temperature protection mechanisms that saves the mobile’s battery from overheating.
