Things You Need to Know before Buying an External Battery Charger

Posted on 14th Aug 2014 @ 3:07 AM

External battery chargers also known as external batteries or power banks are rechargeable batteries that you can travel with and use to recharge all your electronic devices whilst you are on the move. It gives your electronic device, be it your iPad, iPhone or smart phone an extended battery life wherever you travel too regardless of how remote the area is.


However, due to the development of technology, many people have various devices that require recharging while on the move and as a result many companies manufacturing the external batteries have come up. It is therefore not easy to pick out the best external battery for yourself. There are many factors that you ought to consider other than the physical appearance of the gadget.


The following are the things you should consider and that will help you to get the best cell phone power bank in the market that meets your needs.


Consider the capacity

A power banks capacity is measured in mAH (milliampere hours). For a modern cell phone power bank the capacity ranges between 2,00mAh and 20,000mAh. With this in mind, you should get a power bank that has the highest capacity that is within your spending budget. You would rather have a power bank that still has extra charge after you get from your long trip than one that will run out while still on the trip.


To get one with a capacity that will serve you best, you can do an estimation by adding up all the battery capacity of the phone and any other electronic device that you may have. After, you should get one with a capacity that is double or even triple if possible.


Output ports and Ampere output

Many power banks only have a single output charging port, which allows you to only charge a single device at a time. However, there are other 5000mAH battery packs that have two output ports which allow you to charge more than one device at a go. Many USB ports are usually rated 1A. Using such a rating, you will not be able to charge an iPad. However, a power bank with two outputs will have one port rated highly to enable you to recharge your iPad.


Brand name

Due to the increase of counterfeit batteries in the market, it is recommended that you only purchase an external battery pack from a company that is verified as a seller. There are some sellers that rate the capacity of power banks to be high only to realize that you cannot even charge a single device fully. You would therefore be better off paying higher for a high quality battery pack


Additional features

There are some portable power banks that come inclusive with all types of cables, saving you the hassle of carrying yours around.
