## Summary description

PREMIUMCORD kur-21 is a USB adapter cable converting a USB A female port to a USB A male plus a Micro‑USB male OTG connector. It enables connection of standard USB devices to hosts with Micro‑USB OTG support, useful for file transfer, peripherals and charging. Compact and easy to use for smartphones, tablets and other compatible devices.

## Long description

PREMIUMCORD kur-21 is a USB adapter cable that converts a Micro‑USB OTG host port into a USB A female connector while also providing a USB A male connector for external power. It lets smartphones and tablets with Micro‑USB OTG support connect to standard USB peripherals such as flash drives, mice, keyboards, card readers and external hard drives while allowing additional power to be supplied.
Advantages
The adapter supports USB OTG (On‑The‑Go) and enables simultaneous connection of multiple USB devices through a hub. By providing a separate USB A power input, it supplies power to connected peripherals from a charger or computer so the mobile device battery is not drained. The compact cable is compatible with many OTG‑capable phones and has been tested with several Samsung and Sony models.
Suitable for
Connecting flash drives to Micro‑USB OTG smartphones and tablets
Using USB mice, keyboards and card readers with OTG devices
Connecting external USB hard drives via a USB hub to an OTG host
Powering peripherals from an external USB charger while connected to a phone
Key specifications
Brand: PREMIUMCORD
Model: kur-21
Connectors: Micro‑USB male (to host), USB A female (for peripherals), USB A male (for power/computer)
Function: USB OTG adapter with external power input
EAN: 8592220014049
How to use
Plug the Micro‑USB male connector into the smartphone or tablet that supports OTG. Connect USB peripherals (flash drive, mouse, keyboard, card reader, external HDD) to the USB A female connector; if using multiple devices, connect a USB hub to the USB A female first. To provide external power to the connected peripherals and avoid draining the mobile device battery, plug the USB A male connector into a USB charger or computer USB port. The host device must support OTG for peripherals to function.
Usage recommendations
Tested with devices such as Samsung Galaxy S3, S4, S5 and Sony Xperia Z1. Some devices may still charge when this cable is connected even if charging is not indicated on the screen. Ensure your phone supports OTG before use and use a powered USB hub for high‑power peripherals.
