If you are on the move and your cell phone and mobile devices battery goes dead so you can’t use them, this is frustrating and annoying. If this has happened to you – you know exactly what I mean. This is where having a portable power bank charger can make a huge difference in the enjoyment of our mobile devices. Due to technological advances in society, our gadgets provide us with convenience and lightening speed communication. Our smart phones have become lighter, smaller and more economical so much so that people can easily carry them in purse, pocket, etc. In the last 25 years there has been an amazing shift towards buying portable devices that enhance the quality of our lives. Cell phones have evolved from being bulky to being sleek lightweight efficient devices. With the tremendous increase in their usage there is a need to keep them charged at all times. It is for this reason that many companies have introduced Power Banks into the market
A power bank is a portable charger for your mobile devices and it is an absolute necessity if you are a frequent traveler. You absolutely need to be able to charge your devices if you want to fully utilize them on a single trip. Cell phones, tablets, etc., all require power after some time and a power outlet is generally not available everywhere you go.
So if your mobile phone runs out of power and you don’t have a portable charger, you are cut off… in dire straights, not only from losing the ability to call, check email and social media, but it can also lead to not being to to make contact during an emergency situation.
Buying and carrying spare batteries for every gadget is not a practical option either. (Not to mention the additional expense over time.) So its a necessity that you have a portable power bank so you can charge your devices on the spot if necessary.
Your personal requirements will determine what type of charger you need to have. If you don’t carry too many devices when you travel, then you can buy a small and low capacity one just to charge your cell phone. If you need to charge a iPad, tablet, etc., then it’s important to have one with a higher capacity.
The main attribute associated to a power bank is its capacity. This capacity is measured in milli Ampere Hour i.e. mAH. You can’t exactly calculate how many times a specific power bank can charge your device, but the rule of thumb is more mAH rating mean more capacity.
If you have a mobile phone with a 1500mAH battery, ideally a capacity of 1500mAH can fully charge it once. And when you buy a portable power bank, make sure that it can charge the battery of a specific device. By this I mean make sure its output voltage matches with the device you own, because if the output voltage of the charger is less than the device being charged, you will have problems… basically it won’t work.
Of course, the reverse is true, if you have a charge with a larger output voltage than your device, you should be able get several charges for your device.
Should you decide on buying a portable charger, keep your own usage in mind. To meet huge charging needs of consumers, 8400mAh and 11200mAh, (and higher mAh) units are also available. There are chargers that can charge almost any type of device, from all types of companies. This includes laptops, ipad, ipod, tablets, and mobile phones from Apple, Samsung and HTC. Sample Usage Guide…
1500mAh battery : mobile phone – 1 full charge. 5200mAh battery : mobile phone – 2 full charges. Tablet – approximately 50%. 10000mAh battery : mobile phone – 4 full charges. Tablet – at least 100% full charge. Power banks are available for purchase in most countries at various prices and in varying sizes and specs. Before buying one, you should make sure that they are new products and not used merchandise. Used cell phone battery chargers will be a waste of time and money as their life span is greatly diminished.
The life span of a power bank can also be greatly reduced if it is kept in adverse environmental conditions for a long period of time. There are portable chargers whose lifetime is reduced at temperatures more than 45 Celsius. However, at extreme temperatures such as over 70 Celsius there is a high probability that the battery will be completely damaged.
Most current power bank chargers have built in USB charging capability. Some of the older models don’t have this feature. They have a separate cable which one had to carry along with the device. This added to the number of things that could potentially go wrong in using the charger.
After you fully charge your power bank at home, it is a simple matter to connect the device to your cell phone with an adapter and your phone will start charging instantly. The better quality power banks will come with a set of connectors for different device types, such as, Sony, Apple, Samsung, etc.
