A lot of it depends on your personal requirements. 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 smart phone. If you need to charge an iPad, tablet, etc., then you will need a one that has a higher capacity.
- Capacity – Determine Your Usage:
The main attribute associated to a external battery is its capacity. This capacity is measured in milli Ampere Hour i.e. mAH. You can’t exactly calculate how many times a specific external battery can charge your device, but the rule of thumb is more mAH rating mean more capacity.
So if you have a phone with a 1500mAH battery, ideally a capacity of 1500mAH can fully charge it once. And when you buy a portable external battery, make sure that it can charge the battery of a specific device i.e. its output voltage matches with the device you own, because if the output voltage of the charger is less than the device being charged, it won’t work. Of course, the reverse is true, if you have a charge with a larger output voltage than your device, you may be able get several charges.
Should you decide on buying a external battery, keep your own usage in mind. To meet huge charging needs of consumers, 8000mAh and 10000mAh, (and higher mAh) units are also available. There are chargers that can charge almost any type of device, from all types of companies(such as Sony, Kinkoo, Anker). This includes 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.
External batterys are available in almost all the countries at various prices and in varying sizes and specs. Before purchasing you should make sure that they are not used. Used cell phone battery chargers will be a waste of money as their life span is not much.
Life span can also be greatly reduced if it is kept in adverse environmental conditions for a long time. There are external batterys whose lifetime is reduced at temperatures more than 45 Celsius. However, at extreme temperatures such as over 70 Celsius there is a good probability that the battery will be completely damaged.
- Price & Quality:
Apart from battery strength, one other thing which can help you decide which external battery charger is best for you… is the price. But you should not buy a portable external battery which either uses refurbished batteries or which doesn’t contain the basic features e.g. short circuit, over-charging protection.
Several reasons of buying a external battery are that it is portable and will charge your device. You can buy cheap ones with big capacity, but they usually will not charge your gadgets properly, or break down on you.
If you are looking to buy a external cell phone battery charger, we really recommend not going for the cheapest option. This is one of times where you do indeed get what you pay for. A mid-range to upper range price will be a great option with no sacrifice on quality.
Because of the large number of personal devices that we now have such as iPhones, iPads, Ardroids, smart phones, some cameras, GPS, MP4, IPods and Bluetooth to name a few, it’s practically a necessity to have one if you want to make sure that you never run out of battery power on your device. There is nothing more frustrating than running out of battery.
Before I had a External battery, I was on a long drive, using Google Maps with my Android. My car charger stopped working, so my cell phone battery died halfway through the 4 hour journey and I had to find my way without back home relying on stopping and asking for directions several times. After this experience I went out and picked up a 10500mAh charger and use it all the time.
