Living in the mobile world means that wherever we go, most
of them take their smartphones and tablets. But, what happens when our mobile
device runs on electricity? There can be a lot of inconveniences when we
recharge our device while sitting and waiting. This hassle can be eliminated by
having a small portable power bank.
If you want to buy a power bank but don't know what to consider, we will give you an idea of
what type of power bank may suit your specific needs.
What is a power bank?
Essentially, a power bank is a portable charger for mobile
devices. Think of it as a rechargeable external battery that can be used to
charge other devices via a USB connection while running.
Choosing the Right Power Bank
Because they are so useful, power banks are great
promotional items. To select the right power bank, you should consider your specific needs as well as user
needs.
What does mAh mean?
mAh means milli Ampere /hour. It is a measure of the energy
storage capacity of a battery. If you think of a battery as a small fuel
storage tank, which in a sense is a measure of how much "fuel" the
battery holds.
How much power capacity do I need to
charge my phone?
The most important difference between power banks is their
charging capacity. The capacity of power banks ranges from 2,200 mAh to over
20,000 mAh. Power banks with higher mAh capacity can recharge devices more
often than power banks with lower mAh capacity.
Another factor is the mAh capacity of the battery of the
device being charged. For example, the Apple iPhone 11 has a capacity of 3,110 mAh.
And, a Samsung Galaxy S10 Lite has a
capacity of 4,500 mAh. So, if you are using a power bank with a capacity of 10,000
mAh, you can charge at least twice of your mobile battery capacity.
How do you charge a power bank?
You can charge the power bank with the charger using your
phone, computer USB port or simply any other power bank.
What is the time does it take to
fully charge a power bank?
It varies on the battery capacity of the power bank.
The larger the battery capacity, the more charging time you can expect. Type
of charging (like charging on a wall
unit or charging with a computer USB power source) methods may result in different charging
times. Charging with the original power charger will be faster than charging
with a computer USB port.
Number of USB slots
All power banks have at least one standard USB slot for
charging, along with a mini-USB slot for charging the power bank. The large
capacity power banks provide two standard USB slots so that the user can charge
two devices at a time.
Power banks are available in round or rectangular shape.
Therefore, choose a power bank on its size and colour that works well with your
likes.
Additionally, both the size and value of power banks
increase with the increase in capacity. Therefore buy a power bank that has
sufficient capacity to charge a specific phone or tablet at least twice. The power bank with 10000 mAh is good to
buy in the present scenario.
A power bank is not just an emergency device. It is also great
to carry around every day to support almost non-stop connectivity for mobile
devices without tethering to the wall. Since power banks are so useful, they
are a great way to carry with you. Check with different power banks models
before buying. Nowadays there are few attachments like LED lights, small fans
available in the market which can be connected to power banks and used as the
need arises.
