After the blackout that all Spain experienced, the strategies to recharge mobiles and small devices have become increasingly creative. But there is one that could be the most independent of all of them. It is called Campstove and, like a solar panel with the sun, Campstove It allows to load devices, but with fire.
Through an internal thermoelectric generator, this kind of “Campingas 2.0” converts heat into usable electricity and thus feed an internal fan for ultra -efficient combustion. The surplus is Store in the internal battery of 3,200 mAh so you can access energy when you need it.
In total, the stove weighs 950 g, quite heavy for an excursion to the field, but very suitable to get out of home emergency. Above all, if we have firewood or pellets. That makes it An almost infinite and independent energy source of electrical circuits or gasoline.
Obviously, it is better to have external batteries, but these, after two or three load cycles, run out. Instead, the Campstave You can continue to work whenever we will supply some firewood. The disadvantage is that it is not very fast as far as charge is: almost two hours are needed burning firewood to load an empty android smartphone at 50 %.
The advantage is that, taking into account its size, not so much firewood is needed to load the battery and, At the same time, you can cook something, which makes it much more versatile than other devices. In fact, it takes less than five minutes to boil a liter of water. To this we must add that the battery can also be used as a 100 lumens lantern.
Its price is 180 euros, a little expensive if we take into account that a portable energy station can have a similar price and greater load capacity. Of course, we return to The main advantage of Camstave, completely independent.
