A port does not supply electricity
An external USB connection can be a routing feature, but the listing title does not explain the internal cable or power source. Confirm what hardware is included and whether it works with your device and preferred battery. Check how a cable would be stored during use, since charging convenience depends on the whole setup rather than the presence of a port alone.
