Hi guys

I was just wondering if i will need extra power if I want to connect my nexus 5 to a portable hard drive via OTG? If there are any that don't need extra power, what are they? I'm in the UK thanks.

A portable hard drive will need external power. Don't know any that don't. The power draw is too high for the device to handle it.

I have a 250GB Western Digital Passport, 1TB Samsung M3 and a 500GB DIY portable HDD I made with an old laptop drive and USB 3.0 enclosure from eBay... and none of them require an external power supply as they're all USB powered.

Also, when I had a Note 2 I could connect these drives to it... so whilst I can't say for sure they will work with the N5, I don't think it should be ruled out.

I'm at work right now and have no idea where my USB OTG cable is, but if I can find it when I get home I'll test them out.

Since the S3, all flagship Samsung have been able to power OTG Mechanical HDD's.

On the N5, many will not power however recently a few people have said they have managed to do so, but whatever. Generally the advice with the N5 is you need a powered USB hub. Some may work without but we dont have a catalogue of what works.

I'd really appreciate that CitizenLee. The Samsung M3 was the portable hard drive I was thinking of buying and I would be great to know first hand.
