Questions & answers
Can I use my phone while it charges?
Yes — the anti-slip suction cups hold your phone in place so you can chat, scroll, and play while it charges wirelessly.
Which phones does the wireless pad work with?
Any Qi wireless-charging phone — iPhone, Samsung Galaxy, Android. Press the power button to activate wireless, then align your phone (green LED confirms).
How many times will it charge my phone?
Find your phone or iPad in the charge comparison chart above. It shows estimated full wired charges by battery capacity; wireless charging and using a device during charging can reduce the total.
Will the suction cups damage my phone or case?
No — they grip smooth surfaces cleanly and release without residue. If grip fades, wipe them with a damp cloth.
