The Power Bank is for those recommended in particular, who value a small and handy design combined with great quality and a certain extra, namely the UVA lamps. Even if you are traveling a lot in the outdoor, this chic loader proves true blessing! Finally enough power so that you can let the route planner of the phone also safely run all day. In addition, this power bank is charging the phone extremely fast - faster than with the conventional charging cable. It is very easy to use since it is fully charged automatically shuts down by itself and the LED's always show the charging status. The UV light is very bright and can find use for all purposes (authenticity of bank notes, patches, etc.). As for me continues to be very excited about this product, the special external coating that really feels good in the hands. Great quality! Would I buy again immediately !!
