lifesavers

I live for my bluetooths. And my powerbank is usually on my phone but my bluetooth headset is another story. These little things were perfect to charge on the go for my headsets. I literally have 4 headsets and rotate out all day long. So always charging a few.these were great. And small enough to fit in my pocket. Perfect for me.and nice lights on them. My regular power bank doesnt have a light. I needed to use this on my phone one day too and it was slow but did work A++++
