What to know before buying

Listing details to confirm

Listing details conflict or are unclear: a 1.5-hour recharge claim appears alongside a separate estimate of about 4.5 hours using a 30W PD charger, and dimensions and weight differ between listing sections. The product is described as portable despite details stating Portable: No and Cordless: No. Confirm the selected model's measurements, weight and recharge time for your charger before buying. The listed 87W total is shared across devices, while single-device output is stated as up to 65W.

Who is it for?

People who want an integrated USB-C lead for compatible phones or tablets.
