Charging iPhone via batteries.

Okay, on Saturday I'm going to Austria for a week. The problem is we are going on a bus+ferry overall will be around 37 hours. And I'm scared if my iphone goes out of charge I'll need a charger (there will be no plugs on bus) so I have heard you can get ones which go by batteries, so I have had a look and the only good one I could find is: http://www.amazon.co.uk/gp/product/B002VE8PEQ/ref=s9_simh_gw_p23_d2_i1?pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=center-2&pf_rd_r=0526X1BCS6RJDTM0DCMA&pf_rd_t=101&pf_rd_p=358549767&pf_rd_i=468294

Will that be any good? Or has anyone got any better ones? Tbh I don't mind if it doesn't charge fast, just to keep my phone going.

You can buy iphone cases that you can charge as it has an inbuilt battery in it. Let me try find an example.

didnt realise how expensive they was but yeah I think these look nicer as it's not as much as a pain to have around. but I'm sure the one you picked is good enough.
