3. How strong is the magnetic hold?
It offers a reliable magnetic grip, though some users note it may require manual alignment or pressing a button to initiate charge .

4. Can I charge multiple devices simultaneously?
Absolutely. You can wire two devices via USB-C and USB-A while wirelessly charging a third device at the same time.

5. Any known issues or limitations?

• Wireless charging may stop or not work well with devices like Galaxy Watch—wearable compatibility can be hit or miss .

• Magnet strength is moderate; best suited for phones with MagSafe-compatible cases, not all wireless rings .
