There are many, new, types of chargers. Some of them use solar energy, some heat, but all of them are useful. One of the concepts is Eco Charge. This is a portable charger that will turn thermal energy into electricity. The thermal energy can be generated from heaters or some other source. This is a portable system. This means you can carry it with you and use it when and where you want. At the bottom are magnets, so Eco Charge can be attached to any surface you want. Also, it has an OLED display that will inform you how efficient your device is charged.
But why this device is so important? We use smartphones, tablets and similar device too much. A thing that worries me most is that kids use those devices more than adults. We can even say that some of them are addicted. But all of those devices have batteries. In most cases, they are lithium-ion. They are good batteries (they charge fast) but they last very short. An average used must recharge the battery on his device at least once a day. This means the human population is using a lot of electricity. With Eco Charge and similar gadgets we can reduce these numbers.
Thermal energy is wasted in many cases. Luckily, there are devices that can help you use it. Beside this has a positive effect on the environment, it can reduce the amount of your energy bills. Because electricity is more and more expensive, we can see how many benefits Eco devices have. Simply said, they have many benefits, but not a single drawback.
