Can you draw from 2 usb ports for double the power?

I have 2 0.5a usb ports in the back of my TV. Can I combine then to power something that needs 0.9a? It would be neater than running a separate Power supply.

I have a lead does just that for an old external USB powered drive.
So yes probably if you can find a suitable lead.

There's less likelihood of disembowelling your TV if you splice in a powered USB supply from the TV supply.
Replace the end of the kettle lead [Or figure-8 lead] with a twin plug socket, then use a very short kettle lead for the TV and a plug-in adapter for the USB.

You can try. I've got an external hard drive that plugs into two USB ports, one for data + power, the other just for power.

I imagine it would also depend on the board the usbs are drawing that .5a from. It may well be shared.
Probably not, but it could be.
There is no reason to suggest two separate 500ma supplies wouldn't give 1amp out though, so it's certainly worth a go.

One other point to note, my Samsung TV powers off the ports when you put it into standby - so depending on the device, you might want it powered all of the time to save boot times and/or overnight updates etc

That Lead worked fine,

I have a TV mounted on the wall with cables running through the wall.

My TV has 3 USB ports (2 x 0.5a and 1 x 0.9a) I have a kodi box and HDD to go in, both worked on the 0.9a but wouldn't on the 0.5a ports. Using that cable now they both work and everything is hidden behind the TV. Thumbs Up

It wasn't a fucking kettle I linked you to was it? It was a neat and tidy USB powersource. But whatever mate. Happy Christmas.

Or just plug it in via an externally powered USB hub?

I get the impression it runs of some kind of none kettle lead power cable that runs through the wall so he can't really plug anything in as it'll mean a wire going up the wall.

Is that a shared 2.1a or 2.1amp per socket?

Do the sockets give out 2.1amps?

I ask as I've tried various car chargers with these sort of claims and apps on my phone tell me they aren't delivering the current promised yet a branded charger does (proving the app should be accurate).
