What to know before buying

Listing details to confirm

The listing is inconsistent about dimensions: one field gives 13.1L x 5.4W x 5Th centimetres, another gives 5.4 x 5.1 x 13.1 centimetres, and the feature text states 54 × 51 × 131mm. It also lists 20 Volts and 3.25 Amps in general details while the USB-C1 technical output includes 20V/5A. Confirm the dimensions and port-specific ratings for the selected listing. The claimed charge counts and charging times depend on device and usage conditions.
