2600mAh Powerbank-Portable Battery Charger- with 3 Function Flashlight

Screen Shot 2014-11-03 at 4.34.06 PMThis 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 2600 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 iPhone 5S and Galaxy S3. I’ve also been able to charge my first generation iPad to about 50% of its capacity, but this small battery is definitely not meant to be used with tablets. The battery uses 5V/1A for both the input and the output, which is the typical voltage/current for most smartphone chargers.

This battery has a cylindrical look. It looks fairly stylish and well made. One end of the battery features two USB ports – one micro and one regular sized. The other end of the battery is a small flashlight. I’ve seen many such small batteries include a flashlight, but mostly as an afterthought. This one actually looks and works as if it had been designed to be used for this purpose. The flashlight is good, but not great. It is pretty bright, much brighter than your typical small keychain flashlight. However, it is still not as bright as the dedicated flashlights of this size and shape.

At $20 this battery is pretty reasonably priced. I am not sure how reliable it is in the long run, but so far I’ve had pretty good experience with it. It doesn’t have all the bells and whistles of the some of the more sophisticated batteries that are available out there, but so far it has gotten the job done just as advertised.
