Review on 📱 Mini Portable Micro USB OTG Adapter with 4-in-1 SD Card Reader - USB 2.0 Port & SDHC/TF Card Slot for Android or Windows Phones (Micro USB Card Reader) by Joseph Hamilton

As an Android phone user and photographer, I work a lot with SD cards and mobile phones. This type of product has been used since the 1st generation was launched. Pros: 1. Range extender cable package, which is good in some cases.2. The transfer speed is excellent and stable (the speed may be reduced due to your phone's connection and SD card speed) 3. With the USB port, which is a gem, you can connect any USB devices to play on Android devices to work. On the other hand: not yet. Tips: For Type-C users, Micro USB to Type-C Conversion Adapter works with this adapter. The USB port can work with a computer USB mouse or keyboard as input device (some joysticks work so you can play the game with the joystick), plug in your old USB stick or external hard drive as a data backup for your smartphone (photo and video, etc.) and other devices such as cameras, computer data. It's great that you can view and edit documents and photos that you just saved for a school project or a company project that you don't want to "blur". The BEST thing for a photographer is that you can connect your DSLR to your smartphone or tablet as a second screen or use a shutter remote control or create a photo booth.
