The Torras PB50, marketed as the Shell Pro, is a 10,000mAh-class power bank positioned around portability and visible safety rather than raw capacity. The brand says five of its mainstream 10,000mAh power banks have now passed China's new national-standard 3C certification, spanning hook-mounted, ultra-thin magnetic and three-in-one form factors.

The unit is rated 37.5Wh with a USB-C port that tops out at 45W and steps through 5V, 9V, 12V and 15V while adding AVS fast-charge support. Compliance markings list GB4943.1, GB31241 and GB47372 alongside FC and other multi-country safety certifications. A measured self-charge run reached 8.95V/2.17A, or about 19.41W, after PD negotiation.

A flat, body-colored USB-C cable is built into the shell and stays hidden when not in use; measured from the cable exit to the connector it runs about 69cm. The connector is a standard USB-C male head with IN/OUT markings, so the same cable handles both input and output. The brand says the retractable design uses its YogaFlex mechanism for smoother, longer-lasting pulls.

A snap-open hook at the top attaches through a high-density woven strap, letting the pack hang from a bag or keyring for hands-free carrying. A metal power key and the USB-C port sit on one side beneath a 3C mark, capacity label and traceability QR code, and a companion app reports battery health and cell provenance.
