As our smartphones and gadgets are all getting smarter & versatile, Power Bank are also becoming popular tools to provide more power for them to work and last for days.
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 then later use it to charge up a mobile device (withdraw it from the bank).
The Power Banks we’re talking about are good for almost any USB-charged devices. Cameras, GoPros, Portable speakers, GPS systems, MP3 players, smartphones and even some tablets can be charged from a Power Bank – practically anything that charges from USB at home can be charged from a Power Bank – you just have to remember to keep your Power Bank charged, too.
How long does a Power Bank last?
The number of charge/discharge cycles a Power Bank can reliably perform in its lifetime. And how long a Power Bank can retain its charge when not in use?
The answer can differ between models of Power Bank, their internal components and the quality of their manufacturing. Better and more expensive Power Banks can last longer, while smaller and cheaper units may fall short depending on their treatment. Power Banks are generally not used daily, so they often last much longer than 18 months in real-world usage patterns. A good Power Bank can hold the charge for 3 to 6 months with minimal loss. Lower quality Power Banks may struggle to retain a useful charge more than 4 to 6 weeks. In this regard, you get what you pay for, and if you need a long-term emergency power supply consider increasing your budget to ensure you’re not going to be caught short. Most Power Banks will slowly lose charge over time, to a degree influenced by the environment and their treatment.
Nowadays, power banks have become increasingly popular as the battery life of our beloved phones, tablets, and portable media players are outstripped by the amount of time we spend using them each day. By keeping a battery backup close by, you can top-up your device(s) in no time.
