I'm looking to buy an External battery to use for my HTC One & Nexus 7 for when I go away. I'd like it to be at least 5000mAh.
There's so many of them out there and at all sorts of prices, are they all safe? Should I stick with a brand and pay extra? Smaller the better too.
Anything under £25 would be great!
I've opted for http://www.amazon.co.uk/EasyAcc%C2%AE-iChoc-Ultra-Slim-Flashlight-Smartphone/dp/B00EK3UHS8/ref=cm_cr_pr_product_top
It's the right size and looks smart, plenty of reviews.
I used to do that with my older phones 
Its so can can watch lots of films/play games when flying and waiting for flight.
I may also get a cheap Battery Case for my phone to use but not sure about that yet.
not buying myself but others want idea for cheap Xmas gifts for me ♦
You may have a look RavPower. They offer quality products at a reasonable prices. I've one of their 8400mAh(a super handy one) for my wife and a juicy one(10400mAh for just $35) for myself. We've been using it for a few months and we're happy with it. http://www.amazon.com/RAVPower-External-Thunderbolt-Incredible-Optimus-KnightRider/dp/B00861BX7E
You can also take a look at their Qi wireless charger as your models seem to fit in with a wireless way. http://www.amazon.co.uk/RAVPower-Wireless-Charger-Included-Single-Position/dp/B00DMZPQIG
