What is Power Bank?
How often do you carry a charger in your pocket? Most of us will say "always". Modern communication devices, especially smart phones, are used very actively both at home and at work. As a result, battery life is consumed so fast that you need to recharge the phone couple times a day. Needless to say, this is very inconvenient! Carrying your charger everywhere, looking for a power socket, and waiting for your phone to recharge. Unfortunately, a timeless battery has not been invented yet. Power Bank has come to replace all those inconveniences.
Power Bank is a portable battery that can charge any mobile device whenever and wherever. This rechargeable battery has great capacity, approximately 1500-2000 mAh. It’s very simple - the more capacity Power Bank has, the longer you can use it.
How does Power Bank work?
Again, it is very simple! First, charge Power Bank by connecting it to a stationary power source. All "power banks" are equipped with charge indicators that will let you know once the device is charged and ready for work.
Each Power Bank is equipped with a USB output. To charge a device (smart phone, tablet, laptop, etc.), just connect a cable from your smart phone to Power Bank. You can still use your device when it's charging or you can wait until the device is completely charged. Choose that "power bank" the capacity of which exceeds battery capacity of your device. For example, if your battery has 1500 mAh capacity, you'll need Power Bank with 1500-2000 mAh capacity for one complete charge, and Power Bank with 3000-4000 mAh capacity to charge your battery completely twice.
It should be mentioned that you don't need to buy a specific type of Power Bank for a certain brand or gadget. It can be used for all types of devices with a USB output. This means that a single "bank" can charge everything from smart phones, media players and tablet to laptops. Just don't forget to choose the right capacity!
Power Bank will come in handy in a business trip; it can also be useful for travelers and fans of outdoor activities. It is quite compact and light; this means that it will not take a lot of space. This device can be used everywhere: on a plane, in a car, in the forest. Your old batteries are not a problem anymore with Power Bank.
