These power banks are fantastic. I use wireless earbuds on a daily basis but I do not have a great deal of availability to charge them when they run low so having these is a huge time saver. They are portable and easily fit in your pockets! There are 2 power banks and a micro USB Charging cable cord. These power banks give a quick charge and are a great idea to have since most earbuds have only a 2-4hr usage time. You can pop the cord in and quick charge on your pocket.
These are listed to charge Bluetooth wireless earbuds, which they do exceptionally well. You can also use these power banks to give most of your devices batteries a quick charge. Including, Cellphones (android/Apple), mp3 players, tablets, iPods, ipods etc. These only hold a 2200mAh power each which will work perfectly for smaller items with a small charge for bigger items. In addition to its ability to charge batteries these can also be used as small emergency LED flashlights, like if you need a little light to open a door or light a dark path you are all set. Overall I am extremely happy with thesemy only complaint is I wish it came with an additional USB Charging cable cord and maybe a charging block but then again who doesn't have a million of both of them lying around.
