I keep a couple of Sawyer water filters on hand as a "just in case" because losing access to drinkable water is something I don't ever want to experience if I can help it.
GP listed a range. 2 days probably won't kill most people if they're starting at a healthy point and aren't too active or in an arid environment, but it will probably kill a lot of people if they start off somewhat dehydrated or are too active (by necessity or stupidity) during that period. The usual number tossed out is 3 days, but it's not like people will magically all drop dead after 72 hours from their last drop of water. It's an average or expected value.
Yes that's about right. It depends on where you are. On a very hot day in a desert you can die in less than a day. I can't find any exact numbers for this though.
That would be interesting. Can someone who took a Physics class calculate how much energy you could get by cranking (and maybe how many cranks you'd need) to charge this bad boy up?
1 minute of cranking for 30 minutes of play time seems honestly pretty great. Wish I could do that with an iPhone!
I have been in Miami this last week and went to the Mayweather v Paul fight and leaving there was absolute hell. Phone was at 2%, thousands and thousands of people were all trying to get Ubers at once. It was a disaster. Took two hours to find someone who was headed to Hollywood and then I charged my phone along the way and got another Uber back down to my Airbnb. #salty
Could be a cool idea to have a "dual mode bike" that could let you pedal to charge your phone. Anything like this exist lol?
Dynamo lamps have been around for decades if not longer, but they make biking less fun. Output isn't too great either at 6V/3W that seems to be typical. Though it can be bought for cheap 5€ to 36€...
Speaking of charging, does anyone know if usb-c charging is properly implemented? I've bought a number of new devices with usb-c and am disappointed they require the old usb-a to usb-c cable to charge. Has anyone tested with a Macbook charger, or a "smart" usb-c to usb-c cable?
