The feature text claims both USB-C and older USB-A cable use, but the listed connector details do not clearly confirm both port types.

What to know before buying

Listing details to confirm

The listing is inconsistent about the ports: it calls the charger dual USB-C in customer feedback and the title, while feature text claims USB-A and USB-C use, and the technical details list USB and USB Type C. The title claims 20W, while the listed 3 A and 20-volt output details do not clearly establish how that rating applies. The product-details dimensions are also listed as 15 x 10 x 2.5 cm for a cube. Confirm port layout, power output and dimensions on the selected listing before buying. Customer feedback mentions heat and durability concerns, and opinions on charging speed are mixed. The title and feature text claim a two-pack, but the included-components field says "NO". The number of adapters in the selected package is therefore unclear.

Frequently asked questions

How many adapters are included?

The title and feature text claim two, but the included-components field says "NO". Check the selected listing's package details to confirm the quantity.

Does it have USB-C and USB-A ports?

The feature text claims support for both USB-A and USB-C cables, but the connector details are not consistent enough to confirm the physical port layout. Verify the selected listing before purchase.

Is 20W output confirmed for both ports?

The title claims 20W, but the listing does not clearly explain how power is distributed when both ports are used. Confirm the output details if charging speed or multi-device use matters.
