The external power is key because USB is fundamentally a data transfer <\/em><\/strong>standard, not a battery-charging<\/strong><\/em> standard. Charging takes a lot more power than data-transfer; a PC’s built-in USB sockets are simply not designed to pump out lots of power.<\/p>\n\n\n\n

An externally powered<\/em><\/strong> USB hub can provide the USB-maximum-allowed power to each socket, regardless of how many devices are plugged in.<\/p>\n\n\n\n

The better ones also have separate, dedicated “smart charging” sockets to support various smartphone high-speed recharging standards, which operate at voltages and amperages far higher than the USB standard.<\/p>\n\n\n\n

Here’s an example of a hub with its own external, wall-plug, power supply. This one is from Amazon, but there are many, many others. <\/p>\n\n\n\n

\"\"
To recharge many USB devices at once, use a USB hub with its own external power supply, like this example<\/a> from Amazon.<\/figcaption><\/figure><\/div>\n\n\n\n

An added benefit: An externally-powered hub can also recharge devices whether or not the PC is on, which can give you greater flexibility in managing your battery-powered devices.<\/p>\n\n\n\n
