Frequently Asked Questions
Q: Do the 18650 batteries come included with the power bank case?
A: No, the SEamopar 18650 power bank case does not include batteries. You will need to purchase six standard 18650 lithium-ion batteries separately to use the case. This allows you to choose the capacity and brand of cells that best suits your needs.
Q: Is the wireless charging compatible with all smartphones?
A: The 10W wireless charging feature is compatible with any Qi-enabled device, including most modern Android smartphones and iPhones. For maximum 10W wireless output, ensure your device supports 10W wireless charging; otherwise it will charge at the device's maximum supported wireless speed.
Q: Can I use wired and wireless charging at the same time?
A: The power bank case is designed primarily for one active output mode at a time. For best performance, use either the 10W wired fast-charge port or the 10W wireless charging pad, rather than simultaneously.
Q: How do I know how much charge is remaining in the power bank?
A: The built-in LED power indicator displays the remaining battery level at a glance, so you always know when it's time to recharge the case with fresh or recharged 18650 cells.
