There is one thing that makes us panic with a smartphone is to hear the low battery notification, especially if we do not have a charger nearby. What to do? With these five tips, you’ll know how to charge your battery without charger and electricity at all.
1. Charge your smartphone with your voice
If the first reaction you have when you see that your smartphone battery at zero is screaming, do not hold back, shout! Your screams will be good for your battery with the device developed by Sungkyunkwan University in South Korea. The first prototype is capable of generating electricity 50 mV with sounds of 100 dB, which is equivalent to the noise caused by heavy traffic, the passage of an airplane or perhaps that of a heartbreaking cry of rage.
In the future, this system will generate electricity more efficiently and, who knows, we may be able to recharge our smartphone shouting at it.
2. Charge your smartphone with crank
If the first method did not convinced you, the second will surely entice more. For about 70 euros you can get this crank that lets you charge your smartphone. BoostTurbine 4000 indicates the level of your battery charge using LEDs and promises that by turning the crank for four minutes, you get enough battery to make a one-minute call or send a few messages . In addition to charge your smartphone, you can pump up your biceps.
3. Charge your smartphone with wind
This third method allows you to charge the battery of your smartphone with the wind.
This device is called ifan and is currently only available for iPhone. To charge your phone, simply place the ifan on the handlebars of a bike and pedaling for six hours. In six hours, you will have ample time to find a power source to charge your smartphone, but we can only emphasize the originality of the idea that is also environmentally friendly.
4. Charge your smartphone with your body heat
Also enjoy your sleep to recharge your smartphone. You can connect smartphone to you on night. Vodafone researchers developed PocketPower. It looks like a sleeping bag that in eight hours is able to charge your phone enough to make 24 minutes of calls. The idea seems far from absurd especially if you go camping in the countryside, where power outlets are not abundant.
5. Charge your smartphone with fruits and vegetables
The artist Caleb Charland was able to charge a Nokia Lumia 930 with fruits and vegetables. You will need a large wall, 800 apples and potatoes interconnected with cables, zinc and copper, sunglasses and a lumberjack beard. This circuit (the beard is not required) is capable of generating an electric current of 20 mAh average and about 6V, enough to power a smartphone. This is actually a Microsoft advertising that has allowed us to observe the hidden power of food.
