What to know before buying

Listing details to confirm

The listing gives differing port descriptions: the details list three ports and two outlets, while the feature text specifies two USB-C ports plus one USB port and says three devices can charge at once. It also lists a 5-volt output and 3 A current alongside 140W maximum and 145W combined-output claims. Confirm the applicable port and output ratings for your devices. The 140W and 145W figures are listing claims, not verified measurements. For devices drawing under 50mA, the listing says to long-press the button to enter or exit low-current mode, which automatically shuts down after two hours. The 65% usable-capacity figure is the manufacturer's stated conversion-loss estimate, not a guaranteed device charge count.

Frequently asked questions

Can the Ansody S140 charge three devices at once?

The feature text claims simultaneous charging for three devices and describes two USB-C ports plus one USB port. However, its details also list two outlets and three ports, so verify the port configuration for the selected listing.

What is the listed output power?

The listing claims up to 140W for one device and 145W total across two devices. It also lists 5 volts and 3 A, which do not clearly reconcile with those larger power claims. Confirm the output profiles relevant to your device.

How much usable capacity should I expect?

The manufacturer says energy conversion and circuit losses reduce the 25,000mAh stated capacity to 65%, or 16,250mAh. Actual charging results depend on the connected device and charging conditions.

What is included?

The details list a 25,000mAh laptop portable charger, built-in cables and a user manual. The feature text separately specifies one 3.28 ft 100W USB-C-to-USB-C cable, so confirm the included cable arrangement in the selected listing.
