We have come a long way in terms of battery life. But the exponential increase in the number of application that our smartphones have found is outpacing the technological advances in the area of battery life. So, there is continuing search for a perfect partner that would be able to supplement the ever-draining phone batteries.
Basically, there are two most preferred battery back-up solutions – Charging cases and Powerbanks. Most of us face the dilemma of which one to go for. In this article, we would compare these two options by referring to Anker products for better understanding. For battery case, we have Anker iPhone 7 PowerCore Battery Case and we have randomly selected a power bank, named Anker PowerCore Lite 10000.
When it comes to providing total amount of output, power banks easily outperform battery cases. While battery cases struggle to fully charge a mobile phone, a power bank can easily charge the same device multiple times.
For example, Anker iPhone 7 PowerCore Battery Case has a power capacity of 2200mAh that would provide an output enough to charge an iPhone 7 from zero to 80 per cent. On the other hand, the Anker PowerCore Lite 10000 has a power capacity of 10000 mAh that would be able to fully charge the iPhone 3 times.
This is where the battery cases are a better option. A power bank, notwithstanding how small or slim it is, will never be as easy to carry as a battery case. The battery cases are made according to the physical dimensions of a particular mobile to which they have to provide back-up. Thus, the phone fits easily into the case and you can carry the devise without any hassle. While the power banks are like a block that you have to carry around with you.
While the Anker’s PowerCore power bank is the slimmest product in its category it cannot compete against the slim Anker’s PowerCore battery case.
This is a little dicey and depends on the purpose for which one wants the back-up. The battery cases act more like an additional battery when it comes to performance. The power banks by their very nature take a lot of time to get fully charge but take quite less time to provide output to the charging device.
Anker cases takes around 2.5-3 hours to fully charge itself (~80% of iphone 7 battery) and provides output at the same rate to the iPhone. On the other hand, the above mentioned Anker power bank takes around whopping 7-8 hours to get it charged completely. However, it is able to fully charge the iPhone in almost half the time taken by the battery case.
Power banks are able to provide huge capacity of power supply and charge multiple devices but they take long hours to get fully charged and are not so easy to carry. Battery case, on the other hand, are highly portable but they are not able provide huge amount of back-up at high pace and they are highly device specific i.e. if you upgrade your phone you need to upgrade your case as well. So, ultimately it boils down to the user’s preference and need.
