First and foremost, a Power Bank is one type of portable lithium battery pack. Portable Power Banks are comprised of a special battery in a special case with a special circuit to control power flow. They allow you to store electrical energy (deposit it in the bank) and later use it charge up a mobile device withdrawing the power from the bank.
Actually, the Power Banks comes with a package of 5V 1A and or 2A (sometimes 500mA in very small devices) USB output for charging minimal size handsets, digital cameras, MP3 Music Players, MP4 iPods, iPads, tablet, satellite phones or any product that can be charged from standard USB V5 charging.
Now a days, Power Banks have become increasingly popular as the battery life of our beloved high-end phones, tablets and portable media players is outstripped by the amount of time we spend using them each day. Power Banks heels you keeping a battery backup close by, you can top-up your device while far from the wall outlet.
That’s what is Power Bank and how they can charge.
There are some of the most popular and reliable Power Banks available in the market right now. Are good for almost any USB-charged devices, such as Cameras, GoPros, Potable speakers, GPS systems, MP3 players, smartphones and even slates that can be charged connecting via Power Bank. Particularly, anything that charges from USB at Home can be charged from a Power Bank, but the only note to remember is to keep your Power Bank charged fully.
Types of Power Banks Out there?
There are almost three types of chargers found in the market today. One of which is an Universal Power Bank. Comes in many sizes and configurations which can be tailored to your device requirements and to your budget. Secondly, the Solar-Charged Power Bank, these have photo-voltaic panels which can trickle-charge the internal battery when placed in sunlight. Notably, Solar charging isn’t that fast enough, so they can be usually charge via cable as well.
Third and the final cutout is the older-style battery phone case. This Power Bank initiative can be handy and this type of the gadget has a very narrow device compatibility, so don’t go this way anymore.
Last but not least, the Power Banks you choose before you go buying them. You will need to conduct a test drive or read all the specifications and capabilities of those Power Banks. Most commonly, a Power Bank will have a dedicated input socket for receiving power. This can be obtained from a USB socket on your computer, but may charge faster when using a wall socket adapter. Power Banks use a Mini or Micro-USB port for charging and a full-sized USB sockets for discharging.
Power Banks can also use the same USB socket for input and output, but this type is rare and should not be assumed of any Power Bank, as trying to force into an output can damage the battery. For that guidelines, always check the manual for specific instructions if you’re not able to find a clearly marked input socket
Depending on the Power Bank capacity and its current charging level, it can take quite a while to fill up. For example, a 1500mAh rated Power Bank should take about the same time as your typical smartphone with 1500mAh battery package to charge. For larger banks, this time can be doubled, tripled or quadrupled. Most Power Banks have both an LED indicator to show when they are at capacity, and safety cut-off to prevent overcharging and overheating. Once found that, remove the Power Bank from charge when it seems to be fully charged, or at least avoid leaving it connected long-term after its full. Ambient temperature and power flow will also affect charge times, so it’s better to keep it topped off regularly.
Long lasting Power Banks
Considering that there are two important life expectancy on how long does the Power Bank last.
1. The number of charge/discharge cycles a Power Bank can reliably perform in its lifetime.
2. Retain its charge when not in use.
At this point, one can differ between Power Bank models and their inernal components and the quality of their manufacturing. Don’t stock Power Banks which have fewer than 500 charge cycles in them. This would allow you to charge a device from the Power Bank every day for a 1.5 years before it started to lose its ability to hold charge long-term. A cheaper and smaller units may fall short depending on their treatment. Best and more relatively expensive Power Banks with 10,000mAh or 160000mAh banks can last longer.
The quality of the controller circuitry and batter cells depends in two. A good Power Bank can hold from 3 to 6 months with minimal loss. Lower-end Power Banks may struggle to retain a useful charge more than 4 to 6 weeks. Most of which will slowly lose charge over time, Like, leaving a Power Bank in the car where the temperature can fluctuate greatly over time can shorten its lifespan.

Formula that assumes an average device capacity of 1500mAh, a device power level of no less than 20% and an 80% Power Bank efficiency rating up to and 90%, a Power Bank can charge your device. The bigger the Power Bank and the smaller the device you’re charging, the more goes you get. Other factors can also improve or limit the discharge potential of a Power Bank, so look after them and they’ll work better for longer essentially.
Choosing the right Power Bank now
There’s no specific need to make in your mind for buying a Power Bank. Use the aforementioned formula to get a rough estimate of the number of charges a topped-up Power Bank will give before it needs to be recharged itself, then compare your needs and budget to the lineup.
