A power bank can be defined as a mobile charger that can be pre-charged to be used to recharge laptops, tablets, and phones later. This handy gadget can help you charge gadgets without having to plug into the electric socket. It is an important gadget in cases where there are power issues or when one is traveling.
How to charge the power bank
Charging is done in the normal way. You have to connect to the power outlet. Many are also USB powered so that you can charge it using the most common chargers today. There are some that can be used on laptops and they can be charged using adapters that are supplied with them. There are also some solar powered ones that still use the standard charging method.
USB power bank
This is a power bank that can be used to charge all kinds of products that have a USB connection. You simply connect the cable that is used for your tablet or smartphone to the bank and it will recharge. In some, you will have to press a button to start charging. You can only charge when you have pre-charged it. Most of them have LED lights to indicate the progress.
Most of them come with connectors making it possible for you to charge your game consoles, your cameras, tablets, and even smartphones.
Laptop power banks
Laptop power banks come with an adapter to connect to the main and to the laptop when the need arises. There are connecting pieces that make it possible to charge. You should go through the description to find one that is most suitable for your laptop.
How power banks work
A power bank has one or a number of lithium-ion cells. They function just like the usual rechargeable batteries and can be charged using the supplied adapter or cable or through USB.
How long can the power bank last?
How long they last is dependent on its abilities. There is the mAh that indicates the power. When the power is great, it means it will be able to charge more. It also depends on the device that is being charged. A good example is a digital camera. It has very limited capacity. The phones and tablets have a greater capacity while laptops require a lot of power.
To know for sure, then you will have to understand the battery power of your gadget.
How long should the recharge take?
Again, this still depends on its capacity. It takes a longer time to charge it with a greater capacity than one that has a limited capacity. The LED lights included indicate when it is full. You can allow it to remain in the power socket longer even if it already indicates that it is full. Also, if it is new, leave it charging for a whole night.
