Why waste money on energy bills for charging your portable hiking lamp or even your mobile phones, irrespective of the low power consumption for charging these and other devices, when you can use solar cells for the task. These photovoltaic cells convert light energy of the sun to electricity that you can use for charging purposes.
However, finding a suitable charger is tougher than you might think, considering the plethora of cheap and unreliable devices from third world countries flooding online stores. Apart from this, the erratic voltage output of these cheap chargers can potentially damage sensitive equipment like your smartphone by outputting more than the rated voltage and amperage. Oftentimes these chargers do not output the rated voltage & amperage, which defeats the purpose of purchasing them.
It is a good idea to purchase gadgets manufactured by a reputable company. Although you can find this information on online reviews, we have compiled a list of the most popular and effective solar chargers available.
How to choose the best solar charger?
You need to keep several factors in mind when searching online for the ideal solar charger. To begin with, you should only purchase chargers manufactured by a reputable solar brand. Check the wattage of the device and see if it meets your requirements (you will find this information in the pamphlet accompanying the device you wish to charge). Ensure that the charger ships with the right adapters, else you might have to spend more money to purchase adapters separately. Certain solar cells also generate power under dim light conditions… purchase them even if they cost more. Do not purchase devices that require you to purchase a separate charge controller.
Are you aware of the carbon emissions generated by the power plant to generate electricity to power your devices? These emissions lead to global warming and might threaten the planet if necessary precautions are not taken immediately. You can play your role in averting global warming by opting for green energy through solar panels. The added advantage is a reduction in your power bills. Remember, every watt counts in preserving the ozone layer of the stratosphere, preventing dangerous ultra violet rays of the sun from reaching the earth’s surface, preventing global warming in the process.
How much wattage do you need?
How much wattage do you need?When you receive your power bills, it shows the number of watts you have used in a billing cycle. When you purchase any appliance, you will find both volt and watts mentioned on them. Most individuals find it difficult to understand the difference between the two. Here is a simple explanation that will clarify your doubts. Voltage is constant, be it 110 Volts or 220 Volts. The amount of watts consumed determines your energy bills. Your power supplier agency charges you for every KWh (kilo watt hour, where kilo=1000), also referred to as horsepower.
Calculating energy costs
If you are using a device that requires 20 watts, it means that the device can run for 50 hours on a unit of energy (1000/20=50). Similarly, a device rated at 10 watts will consume one unit of energy after running for 100 hours. In simple English, devices rated with a higher wattage consume more electricity. You should keep this in mind when purchasing a solar charger. If you want the charger to charge multiple devices at the same time, add up the individual wattages of each deice to calculate the wattage you need, and search for a charger that can output that amount of wattage. Here are some examples.
- Kiizon 25000mAh: 1.8 Watts
- Nekteck 21W: 21 Watts
- BigBlue: 28 Watts
- RAVPower: 24 Watts
- Suaoki: 60 Watts and 100 Watts (depending on the model)
- Jackery Portable Solar Generator: 500 Watts
Integrated or external battery
My personal preference would be for portable batteries, as this would allow me to keep extra batteries that I could use while charging the discharged one. Unfortunately, not all companies manufacture portable chargers that work with external batteries. This should not make much difference if you charge the battery during the daytime and the battery has enough capacity to power your devices after sunset. Another disadvantage of chargers containing integrated batteries is that you have to return the unit to the manufacturer if its battery does not function properly. Eventually, you have to take the decision after balancing the pros and cons of the charger.
Portability and durability
Portability and durabilityIt makes no sense purchasing a solar charger for charging devices while on the move if you cannot carry it with you. Obviously, it is a better idea to install a solar panel on your rooftop if you want to charge devices inside your house. Therefore, portability is the primary aspect that you should check for before purchasing a solar charger. The weight of the device should be light enough to carry around without any problems. The dimensions of the unit are also an important factor, especially if you want to pack the device inside your backpack. Durability is the second aspect. Solar chargers are quite costly and you typically depend on them while you are in places where there are no alternative power supply options available. Therefore, purchase a charger that can withstand rough use over sustained periods, without compromising on its rated power output.
