If the Sun shines, never again run out of power when out and about…….
Suntactics, a Californian company who have been making solar chargers for some time, have just come up with what seems to me to be an ideal solar charger for just about any mobile device you might happen to have, with the possible exception of laptop computers.
Glorying in the name sCharger-5 This baby delivers 5 Volts at 1 Amp when the sun is shining, which is enough to actually run most portable devices, such as ereaders, which is why I am telling you about this one, of course.
Apparently the secret is that this charger uses industrial quality high efficiency mono crystalline solar cells, which are designed for high output, unlike most small Solar Chargers, which are basically trickle chargers working through an internal battery. The sCharger-5 has no internal battery to wear out, but is a direct source of power. Obviously this has its down side, in that no sunlight, no power. But to get around this, they point out you could buy a USB battery or if your device uses AAA or AA batteries, get a USB charger for these batteries, and use this Solar charger to charge those batteries…..
It works via a standard USB connection, so basically any mobile device that can be charge via USB, will work with this one.
Or as they put it in their Press release:
This not an ordinary small solar charger. These use high efficiency mono crystalline solar cells like the ones used in industrial grade solar systems. The sCharger-5 output power is over 5 watts. See if any other small solar charger can match that power in such a small package!
Most other solar chargers use low power solar cells that produce a tiny amount of power. They use the small solar panel to trickle charge an internal battery, which takes forever! The small solar panel on them is not enough to charge your device directly. They essentially charge your USB device from their internal battery. When the internal battery fails(which it inevitably will, since it’s being baked in the sun constantly), you have to throw the whole thing away. The sCharger-5 will not only charge your device, it will run it directly from the sun.
Don’t be fooled by the 6 to 7 watt 12 volt solar chargers out there. They are not optimally setup to do USB charging. They require a DC converter to convert 12 volts to 5 volts that USB devices require. This comes out to less power and your smart phone or GPS device will have a hard time charging.
