Nexus 5 may be the smartphone of the moment, but that doesn’t mean that Samsung’s flagship should not get any attention. The SGS4 is still a very capable device, despite the insane speed at which mobile tech evolves, and a battery pack can only make it better.
The standard battery of Samsung’s Galaxy S4 has 2,600 mAh, which for a mobile phone should be more than enough. However, the SGS4 packs a powerful CPU, an equally potent GPU and a Full HD display, all of which can draw a lot of power when used extensively. Considering the habits most of us have when it comes to smartphone usage, it’s no surprise that the battery drains so fast. In most scenarios, the battery of our smartphones needs to be recharged on a daily basis. The Xtorm battery case power pack has a capacity of 3,000 mAh, so at least in theory it should double the standby time of the smartphone.
There is, however, something that makes the Xtorm battery pack rather unique among the accessories made for the Galaxy S4. Its back features a solar panel that enables users to charge the built-in battery when on the road.
Among the best things about the Xtorm battery case is the fact that it can use solar energy to charge even if it is not connected to the smartphone. That’s great, since exposing the Galaxy S4 even to indirect sunlight might not be the best idea ever.
As a downside, the Xtorm battery pack increases the size and weight of the smartphone. Because of this, users should only attach it when the smartphone’s battery is low. The bulkiness is not always a drawback, as the case also improves the protection of the phone, thus reducing the consequences of physical impacts. Overall, the Xtorm is an accessory worth looking into, as it comes with great features at a relatively low price.
At $70, the Xtorm power pack is quite affordable, especially considering its features. On the other hand, there are power banks out there with a higher capacity than that (I’m thinking about the 12,000 mAh Battstation Tough Dual Pro, for example) at the same price. Depending on where and how you use your smartphone, you might consider one option better than the other. After all, power banks are often hefty, despite their portability.
