Easy operation, easy connection

M141 OTG micro SD Reader is suitable for mobile devices that support OTG interface. Once the TF card is inserted into M141, it has two interfaces Micro USB & standard USB2.0 simultaneously. The files, photos and multimedia files on smartphones/tablets running Android systems can be stored onto the M141 through the Micro USB interface and the multimedia files previously saved on the M141 can be browsed directly. The other end is a standard USB2.0 flash drive that can be connected onto the computer by itself for use to easily save the files into the computer or play them on the computer.

Real-time transmission, sharing life

The maximum transmission bandwidth of the Micro USB port on the M141 dual interface mobile flash drive used to connect to mobile phones and tablets is 480Mbps, which is must faster than Wi-Fi and Bluetooth. It can provide fast data exchange services and save on mobile internet traffic and it is not restricted by wireless hotspots so multimedia data can be shared at any time and place. Also, by using the USB2.0 flash drive, it can be connected to computers directly to access data, allowing you to enjoy outstanding mobile storage life.

Capacity expansion, unlimited storage

M141 has three transmission interfaces simultaneously; not only can it be used as a storage medium for smartphones/tablets and ordinary computers, it can also solve the problem of insufficient built-in storage space of mobile devices which cannot be expanded. In addition, by pushing the yellow latch to remove the micro SD card easily, the micro SD card can be replaced at any time for unlimited storage capacity.

Compact, lightweight, convenient to carry

The M141 has a matte etching design on the exterior, along with calm and astringent black colors. It also has a thoughtful dual-cap design that makes it dust-proof and can prevent collision of the USB connector. It is lightweight, compact, and goes very well overall when used on smartphones/tablets. There is a strap hole in the cap that allows it to be strapped onto places, making it more convenient to carry.
