Surely it has happened to you during a busy day outside your home or office and given the frequent use of your smartphone, tablet or any other portable device you have with you, at some point it will notify you for “low Battery”.
That’s where you “make a stand” so that the battery lasts until you come back later at home or in your office. With a power bank, however, you would simply connect them to each other and within half an hour you would have an adequate battery once again to use it fearlessly to the final drop.
I bet you’ve heard of power banks and you certainly know about what this little useful gadget has become especially popular lately.
For those who want to be equipped with a power bank, Battery Club presents to you today in detail what it is and how it works, so that the power bank that you will buy to meet all your needs.
Battery Charging On The Go
Power banks are small portable chargers (usually the size of the mobile phone) that allow you to charge your mobile on the go. They usually have a 2-port minimum, one to charge the phone and one to charge the Power bank itself.
There are also power banks which have 2 USB outputs so you can charge two devices at the same time. There are also models with a power outage circuit in case of short circuit, overload circuit that interrupts charging when it reaches 100%, lens and also car battery boot system. Finally, some models are lined with small panels thus collecting solar energy, in addition to electricity.
With a power bank, whatever its distinctive features, you have a spare battery with you, which works just like a bank that stores energy and allows you to “save” your device from inevitable deactivation, without Not need a plug or charger.
Power Banks doesn’t have software, so you don’t have to worry about it being compatible with your smartphone. In the majority of the power banks are compatible almost any device accepts USB cable: cameras, portable speakers, GPS systems, Mp3 players, smartphones and tablets.
What to consider before you buy a power bank
The general operating principle of power banks may be the same for all models, but their performance varies and, as with any technology product, so is the post “what you pay, you get”. Capacity and portability are the most important factors to consider when you want to obtain with a power bank.
If the manufacturer does not explicitly mention it otherwise, expect 70% of the profitability to be achieved. E.g. a power bank 10,000mAh can render 7,000mAh. Some of the best power banks in the market attribute 90% of their capacity. For a full charge of a mobile you will need a power bank with a capacity of 1,500mAh, for two full charges, a power banks capacity of 5,200mAh and for 4 full charges, a power bank 10,000mAh.
To calculate how many times a power bank will charge one of your devices (MP3 player, smartphone, tablet, camera, camera, laptop, car, anything that can be plugged into a micro USB/USB port anyway), as long as you know the battery capacity Of. If it is for example at 2,000 mAh while your power bank is playing at 2,200mAh, then you can calculate marginally on one charge.
In general, keep in mind that the more mAh, the more charges and the heavier and bulky the power bank and the higher the charging time. On the contrary, the fewer mAh, the fewer charges, but the lighter and easier to transport and charging time.
Some power banks are small and light enough to slip into a pocket. Others are larger in size and will need a bag to carry. Pay great attention to weight and avoid bulky power banks if you intend to carry them with you every day and not just in some cases.
You can charge your smartphone from a power bank every day for 1.5 time, until it loses its ability to recharge. This means about 500 charging cycles on average. More expensive power banks can last longer and cheaper and smaller maybe less. If you do not make daily use, power Bank will operate without any problems over 18 months. The life of a power bank can also be reduced if exposed to high temperatures (e.g. in the car).
Charging in five minutes?
Lately there have been several news stories about power banks that charging in 5 minutes. The titles are correct but at the same time misleading. The truth is that the power banks themselves do refill their own battery in five minutes to be able to charge the smartphone battery – not the smartphone battery in five minutes.
Techodom – a leading technology shopping guide blog – has created a guide for finding things to Buy With 100 Dollars or Less. In that guide they list several power bank models that cost less than 100 USD. Maybe you should give it a shot..
