This gadget could make you feel like you are contributing to the world. Why? Because you could be charging your devices using the energy from the sun and nothing else! Even if you would upgrade from electricity to solar power on a very small level but it is still one step towards saving our earth. Sounds like a very great idea but let's get into the product in more detail.
First of all, it obviously receives energy directly from the sun, the solar panel is 4.5 volt and 0.4 watt. You can expect this gadget to recharge a 2000 mAh Lithium-Ion battery. That means you are able to charge newest generation phones and devices. The GreenLighting Solar Charging Battery has a suction cup which will allow you to use them on windows. According to the provider it will charge your phone up to 40%. It is supposed to do it within 4 hours. If you have a cloudy day you may charge it via USB and save it for later. On this gadget you will see 4 blue lights on the back that indicate how much the internal battery has energy. The green light will show whenever this GreenLighting Solar Charging Battery is charging or not. The dimensions are 4.5 "x 1.5".
Most of the reviews I have read are from Amazon . Majority of the reviews are good about this product. I have learned that this gadget has 2 most common problems.
- The suction cup does not work properly
- The charging speed is slow
Keep in mind that in dry air blankets cups do not work as good. You may also rest the GreenLighting Solar Charging Battery on something because the gadget itself could be heavy for the suction cup.
The charging speed is completely dependable on the window type. We are at this point of technological advancement where windows can reduce the sun light power significantly. So if you would want to put this charger behind your windshield or new windows keep in mind that it will make a huge difference. If it's sunny best to keep the windows open if its too cold keep in mind on the difference it will make. Other reviews are not specific or subjective which is why I will not mention them.
If you really love the idea of a green earth or you live in a place where sun is shining all the time than I would recommend the GreenLighting Solar Charging Battery for you. The reviews are not as good as we would like like it to be but, in my opinion, it should be higher. Some of those people most likely did not think through about solar panels being behind windows. The only technical problem is the suction cup but you may overflow it very easily.
