Hi All, I am after a bit of help finding information on subject lantern. I bought a couple of some while ago but have never used them. I have done web search to no avail. I know a 1 minute wind gives 20 minutes light but there is a connector for the car 12volt system. If it is used then how long do you charge it for? How long does it last when charged this way? I approached the company who told that due to trouble some while ago they have lost all information they had on subject item. If I could be pointed in the right direction I would most grateful. Cheers
