When I heard of this product, I thought there are three USB ports, but actually there are only two USB ports and one attached Micro USB cable. The description actually meant you can charge three devices at one go because it is able to output a maximum of 5A.
When I received an email from Bolse asking me to feature their products, I was pretty skeptical because I have never heard of Bolse before. So I went to do a search on them and realised that their products received pretty good ratings on Amazon and the prices are pretty reasonable. They are the direct competitors to brand like Anker.
