Built-in USB-C and USB-A ports also allow wired charging for up to three devices at once. Buyers whose phones lack MagSafe or who need faster than 15 W wireless output should consider alternatives.

Wireless charging peaks at 15 W while the USB-C port delivers up to 20 W PD fast charging. The USB-C input accepts up to 18 W for recharging the bank itself. Pass-through charging lets the bank and a connected device charge simultaneously. Five LED indicators show remaining capacity.
