This is a very convenient and small external battery charger. It’s ideal for the on-the-go situations where you want to be sure that you’ll have extra power on hand in the case your smartphone runs out of power.

The 3000 mAh battery capacity is nominally sufficient to fully charge most smartphones out there. For instance, iPhone 5S battery capacity is little over 1500 mAh, while Galaxy S4 has a 2600 mAh battery. Keep in mind that there is some inefficiency associated with the charging process, so that the amount of power that you get will be about 80%-90% of the nominal battery capacity. I have been able to fully charge my iPhone 4S and Galaxy S3. I’ve also been able to charge my first generation iPad to about 40% of its capacity, but this small battery is definitely not meant to be used with tablets. The battery’s output current is 5V/1A which is much more suitable for smartphone charging than for tablets.

This battery has a very interesting and artistic look. It certainly jumps out in terms of its look compared to most other products in this category. It almost feels like a piece of jewelry, although its cheap plasticky feel will quickly dissuade you from thinking too highly of its value.

This is not the highest quality portable battery that you’ll come across on Amazon, but it is still decently made and will probably serve you a while. I think it’s well worth its very competative price.
