Steripen UV water sterilisation
This is a steripen ultra rechargeable via a micro USB port. I've only used this a few times and it can be used 8k times before you have to change the bulb. To the people who say they wouldn't trust it. I drank tap water in New Delhi with this and didn't get sick. Here's a description below... I am in Hofn but I am willing to of course discuss postage options.
