It started off as a more elegant (and faster) alternative to parallel and SCSI computer ports, but now that USB can even be used to charge everything from phones to cameras, there never seem to be enough of them. It's, admittedly, a first-world problem, but one that's now thankfully solved with this plug-in tower that includes 40 powered USB ports.
If you're just charging smaller devices like your iPhone you can actually have 40 of them plugged in at one time. But if you need a heavier draw for something like an iPad, you can only have 16 of them concurrently charging.
The products is currently only available through Amazon.com, so if you are in dire need of copious USB connections it will not be super-simple to get it shipped to you – but where there's a will, there's a way. [Amazon via 7Gadgets]
