After purchasing the 3 port version I decided to buy this with 4 ports. Impressed with this power unit from #Poweradd https://www.amazon.co.uk/gp/product/B072P29R65/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 The 4 usb ports will be very handy and what I also like is that it's so lightweight unlike some units.
Very quick delivery too #RankBoosterReview #Sponsored #Poweradd
