Product Overview

A reader built around older Android phones and tablets as much as around laptops: it carries a USB-A connector at one end and a micro USB connector at the other, so a microSD card can be read on a computer or on a phone with OTG support. It is published in four colours, which is unusual in this category and makes it useful where a promotional programme wants the accessory to match a brand palette rather than default to black.

Key Benefits

Four published colours: black, blue, green and white, which most readers do not offer
USB-A and micro USB connectors, covering computers and older Android devices with OTG
USB 2.0, plug and play with no driver
Small, light and cheap enough for volume promotional use
