Where can I buy one in the UK?
Also, does the Meridian need to be connected to the iPhone to charge it?
Thanks, but pretty sure it isn't MFI certified that one...
Buy it directly from Lenmars Website.
You definitely want an MFi certified one too.
Found it:
MFI Apple Approved - Lenmar Meridian iPhone 5 Rechargeable Extended Battery Case for iPhone 5 - AT&T, Sprint, Verizon - Black - 100% Additional Battery Life (2300mAh)

Are we sure that's a genuine Lenmar?
No I recommend you get it from lenmars website
Great ideaIf you write to them and tell them you want to buy one they will direct you to a reseller. When I was looking for one they emailed me with a Canadian amazon reseller and even gave me a 20% off code.
