You are in the desert. You have warmed up, you are thirsty and the worst of all, your phone ran out of battery. You discover that you have some drops of water in a canteen, which you hadn't seen before. What do you do? 1) Do you drink them or 2) Do you use them to charge your phone?
Powertekk is a portable charger, into which you can add a few ml of water and it in turn will silently charge your device.
Its 1,500 mAh battery can output 5 watts via USB to charge a small device such as a mobile phone.
Do you wonder where you would need such a charger? The idea is that it is extremely lightweight (just 30 grams) so you can take it with you anywhere, from hiking to vacations in a place that has no electricity, without worrying about whether it will have sun or not. And what happens if you don't have access to water? Then, you probably have bigger problems than charging your iPhone.
