In an era where smartphones and tablets are replacing laptops, the need for fast and convenient data transfer is growing. One solution that enables direct connection of accessories to mobile devices is USB OTG.
Combined with the modern USB-C connector, this feature unlocks new possibilities – especially when it comes to using USB-C flash drives. Find out what OTG really is and why USB-C storage devices are becoming increasingly popular.
What is OTG?
OTG (On-The-Go) is an extension of the USB standard that allows a mobile device, such as a smartphone or tablet, to function as a USB host, meaning it can control other devices connected via a cable or adapter. This enables you to connect accessories like a keyboard, mouse, flash drive, external hard drive, or even a gamepad – all without the need for a computer.
How does USB OTG work?
Thanks to the USB OTG function, the phone takes on the role of a controller, allowing you to use connected accessories. All you need is a compatible OTG cable or adapter to unlock new possibilities. This solution is especially useful when working in the field, during a computer failure, or when you need to quickly transfer data.
How to check if your device supports OTG?
Not all mobile devices support the OTG function. To verify this, it’s a good idea to use apps like USB OTG Checker or USB OTG Checker Pro. You can also check the manufacturer’s specifications or search online using phrases such as USB OTG device, USB OTG compatible, or USB OTG host.
Types of connectors: micro USB vs USB-C
Initially, OTG was mainly used in phones with a micro USB port, through micro USB adapters or micro USB OTG cables. Today, more and more smartphones come equipped with a USB-C port, which has led to the development of a new generation of accessories: USB-C flash drives, USB-C OTG cables, and USB-C host adapters
Why is USB-C replacing micro USB?
The USB-C connector offers several advantages: it is symmetrical (the plug can be inserted either way), allows faster data transfer, and supports higher power delivery. Moreover, USB-C is a widely supported standard not only in smartphones but also in laptops, tablets, and game consoles. This makes USB-C OTG the new industry standard.
USB-C Flash Drive – Modern OTG Storage
USB-C flash drives with OTG functionality are becoming increasingly popular. Why?
No need for adapters or extra cables
Support for high-speed file transfers (e.g., USB 3.2)
Compatible with a wide range of modern devices
Available in dual versions – with both USB-A and USB-C connectors
This makes them an ideal solution for quickly transferring data between a smartphone and a computer.
Using USB OTG with a flash drive
With OTG, you can:
Open and edit files directly from a USB drive
Transfer data between mobile devices and a flash drive
Watch movies or presentations from external storage
Back up phone data without using the internet or cloud services
For businesses, it’s a great solution for quick data backup during business trips.
Who are USB-C OTG flash drives for?
Photographers and content creators – for quickly offloading photos and videos from a mobile device
Technicians and service professionals – for backing up data without access to a computer
Sales representatives – for presenting offers and marketing materials across different devices
Students and pupils – for transferring files between a smartphone and a laptop.
What to look for when buying an OTG flash drive?
When choosing, it’s worth checking:
USB standard (e.g., 3.0, 3.1, 3.2)
Connectors – whether it has only USB-C or both USB-C and USB-A (dual)
OTG compatibility – not every USB-C flash drive supports OTG!
Storage capacity and read/write speed

OTG Adapter or USB-C Flash Drive?
Both solutions have their advantages. An OTG adapter lets you connect various types of devices, such as a mouse, keyboard, or memory card reader. On the other hand, a USB-C OTG flash drive offers convenience and mobility – ready to use without any additional accessories. It’s best to have both options on hand – for different situations.
