Lumsing

 I have tested a great number of mini power bank, which range from the less powerful 2000mAh to 15,000mAh. This particular power bank is rated at 8000mAh which is adequate for charging smartphones and the smaller electrical items. It is one of the more beautiful and sleek chargers I have been sent and tested. Its body has a wonderful matte black metal casing, it has a bright LED torch, which is more than adequate. At the top there is also a USB, a micro USB slot and the on/off button. There is a small blue LED charging light, but it does not show actual charge, which is the only criticism of the product.

It comes with a white USB lead needed for charging. Once fully charged its capacity to charge my mobile phone is very good. It has charged my phone from about 25%, 4 times and the capacity LED still shines. I have been unable to deplete its charge.

This is a beautifully made, slim and sleek charger with a very large capacity. This is perfect for travelling around where weight and space is of a premium. I am very happy to Highly Recommend the product.
