FAQ

How long is delivery?

EU: 7–15 business days · Worldwide: 10–20. Tracking provided within 48–72 h from dispatch.

Which payment methods can I use?

PayPal, Shop Pay, and all major debit/credit cards via secure checkout.

What is your return policy?

30-day return window. Contact support with your order number for RMA & instructions.

Is there a warranty?

Yes — 12-month limited warranty covering manufacturing defects.

What’s in the box?

USB 3.0 to USB-C OTG adapter ×1. (Cables/USB drives shown in photos are not included.)

Will it work with my Android phone?

Most USB-C Android phones/tablets that support OTG will work. Enable “OTG/USB accessories” if your device requires it (found in settings on some models).

Does it support iPad Pro / iPad Air with USB-C?

Yes — iPadOS supports USB accessories and external drives (exFAT recommended for large files). Some peripherals may need power via a hub.

Can I use it for video (HDMI/DisplayPort) or Thunderbolt devices?

No — this is a data/peripheral OTG adapter only. It doesn’t convert to HDMI/DP and isn’t a Thunderbolt adapter.

Will it power external hard drives?

Low-power 2.5” drives or SSDs may work; for power-hungry devices, use a powered USB hub. Phones have limited USB bus power.

Which file systems are supported?

Android and iPadOS typically read exFAT/FAT32. NTFS read/write depends on the device/vendor; exFAT is the safest choice for large files.
