A portable charger has to fulfill a few basic things. It has to be reliable; it has to deliver great charging performances, and it has to be big enough to store enough power to charge the devices that need that extra power kick. If you’ve ever been in a situation that required you to use your phone, only to discover that you have no battery left, you know what it means to have an alternative.

Travelers and businessmen have made it clear to the manufacturers that practicality and performance are way more important than anything else when it comes to portable chargers. There is no need for fancy gizmos, if the thing doesn’t deliver the juice and the power your device is in desperate need for.

Smartphones have become an essential part of our daily lives. We’ve become dependent on them in so many ways it would take hours to even list them all. However, for whatever things you may use them for, in the end it all comes down to one thing: having a reliable smartphone or other communication device.

Smartphone batteries, unfortunately, still have their limits. Whatever new technology there might be invented to use on our smartphones, it often comes down to what the power consumption of the new app or feature is.

Before cameras and color screens, the batteries of mobile phones were holding a lot longer than our current generation of smartphones. The batteries today are just slightly better than the older ones, but the older ones didn’t have to handle all the features we have today.

One of the biggest power consumers on our smartphones is the WiFi receiver. This little device helps drain our smartphones to the bonce in matters of hours, and we haven’t found a better battery yet than what we have right now.

The only thing that can prevent our smartphone batteries from draining are portable chargers like the “Anker Astro E1 5200mAh Candy bar-Sized Ultra Compact Portable Charger” model we’ll review here.

The incredible capacity it offers combined with the stylish exterior of this device make it seem as if it were a luxury product, but you’d only pay a fraction of what a luxury device would cost.


The true potential of devices like this comes to shine in comparison with other devices of similar caliber. That’s why we compared this portable charger with the “Innogie Dual USB 13400mAh AlienPower Portable Charger” model. First of all, we have to mention that the overall design is not really the issue with this device as it is the charging time. The Anker model simply chargers smartphones and tablets much faster than this Innogie portable charger model, and that’s a big plus for the Anker model.

The other product we compared it with was the “Crave Travel Pro 13000mAh Dual USB Ultra-High Density Power Bank” model. This portable charger is a high-end product. The capacity is astonishing and the charging time was pretty good as well. However, in direct comparison with our Anker model, we found that charging the battery itself took significantly longer with the Crave model, and thus we think that the Anker model simply is the better product.


Although the “Anker Astro E1 5200mAh Candy bar-Sized Ultra Compact Portable Charger” model has a lot of competition in the market of portable chargers, in direct comparison it does its job rather well, and sometimes even slightly better than the other products. It’s reliable, fast, and budget friendly. If you’re looking for these features in your portable charger, then you should definitely try this Anker model out.
