That Pen Drive Won't Read on Your Phone? Here's Why
okay so you have a pen drive full of photos or documents, you want to copy them to your phone, no laptop nearby and then you discover that your phone just will not read the pen drive no matter how you try to connect it. this is the moment most people in india discover they need an OTG adapter and have absolutely no idea which one to buy. OTG stands for On-The-Go and what it does is simple but important it flips your phone's role. normally your phone is the device that gets connected to things. with an OTG adapter your phone becomes the host meaning it can now read and control USB accessories like pen drives, keyboards, and mice. a Type C OTG adapter is the one you need in 2026 it has a USB-C plug that goes into your phone and a full-size USB-A port on the other end where you plug in your pen drive. almost every android phone released after 2021 uses USB-C now, which is exactly why searches for Type C OTG adapters grew 28 percent year-on-year in india in 2025. browse fast charging accessories India at GrunX where OTG adapters, USB hubs, and converters are clearly organised alongside charging gear for Indian devices.
the three product names that confuse everyone OTG adapter, USB hub, Type C converter are not the same thing and getting this wrong means buying a product that technically works but does not do what you needed. here is the short version: an OTG adapter connects one USB device to your phone and gives it host capability right for a single pen drive, mouse, or keyboard. a USB hub splits one port into three or more and lets you connect multiple devices at the same time right when you need a pen drive and a mouse and a keyboard all connected together. a Type C converter only changes the connector shape from USB-A to USB-C without adding any host functionality right when you already have a USB-A cable and just need it to physically fit your newer USB-C phone. the most common mistake is buying a converter instead of an OTG adapter it fits the port but the phone will not read any device because host mode is not enabled. GrunX customer support confirms this is the most frequent query they get about OTG products confusion before purchase, not a faulty product after.
before you buy any OTG adapter it is worth checking if your phone actually supports OTG most phones after 2015 do, but budget phones under Rs 15,000 can sometimes be exceptions. go to settings and search for OTG if the option is there your phone supports it and some phones need it switched on manually. or just plug a USB drive in using an OTG adapter and see if your phone shows a notification to open the drive that confirms it is working. the quick use case guide is the most practical way to choose: one pen drive to connect means a basic Type C OTG adapter. pen drive plus mouse plus keyboard together means a USB hub with OTG. an old USB-A cable that needs to fit a newer USB-C phone means a converter. camera SD card means an OTG adapter with card reader. small USB fan or LED on the go means a basic OTG adapter. get the use case right first and the product name follows automatically. for a cable that combines OTG support with 240W charging and all connectors on a keyring, the GrunX 100W USB-C data transfer cable is a practical option for daily carry and data transfer use in India.
