What to know before buying

Listing details to confirm

The listing says up to 140W for one device and 145W across two, while also claiming three-device simultaneous charging. It does not clarify three-device output allocation or confirm port-specific limits. Its details list generic 3 A output and 5 volts, which do not explain the higher wattage claims. Confirm laptop compatibility and the charging profile required by your devices. For devices drawing under 50mA, the listing says to long-press the button to enter or exit low-current mode. It also claims a 65% conversion efficiency, so the 25,000mAh rated capacity should not be read as 25,000mAh delivered to a device.

How much of the 25,000mAh capacity is available to charge devices?
