Common connectors include Lightning, USB-A, and USB-C. Some keychain-style cables also include built-in adapters such as USB-C to Lightning.
They use carabiner rings or clips. Examples from listings include carabiner rings, attached carabiners on power banks, and carabiner clips on keychain cables.
Many carabiner power banks include LED indicator lights that show remaining battery level or charging status.
Typical outputs listed include 12W for USB-A or USB-C ports. Some keychain-style cables or adapters indicate support for higher power—up to about 60W.
Listings vary: some products support charging one device at a time (1 max), while others support charging two devices simultaneously (2 max).
Available designs include protective silicone covers or port covers, tassel-style housings that conceal cables, and wrist-strap styles that integrate a cable and a carabiner.
