What Should I Know Before Purchasing a Solar Charger?

When choosing solar chargers there are multiple parameters that you must be aware of and that you should take into account when selecting a specific model.

Efficiency

The first parameter that you should look for when selecting a solar charger is the efficiency of the solar cells Almost every solar charger will be based in monocrystalline solar panels, the only way to differentiate one from the other is considering the efficiency values that the cells are designed for. 

The portable solar charger market is often a little bit above in terms related to efficiency when compared to regular size solar panels, generally, efficiencies between 20% and 25% should be selected when looking for solar chargers. Currently, choosing a solar charger with an efficiency value of 17%-19% would already be too low for the current status of the market.

The efficiency will be an indicator of how much solar energy can be converted into DC electricity through the solar cells, therefore is one of the top factors that you should consider. 

Power Output

The next parameter that you must add into your analysis is the power output. Generally, power outputs for solar chargers will be located between 10W and 60W. The power output gives a reference of the electrical current output that can be obtained from the solar charger, higher power output will mean that you will be able to charge more devices faster. Most solar chargers are rated at values close to 25W which will be enough to charge most common electronics such as smartphones and other gadgets.

Portability

Another parameter to consider is related to portability. Most solar chargers will have small sizes and have a lightweight, it is a basic requirement. However, some of them are more suitable for demanding activities such as hiking where weight and size are very important, while others may also be suitable for camping, picnic or maybe fishing activities where the weight and size do not constantly impact in the activity that you are doing. 

All solar chargers will have a folded size dimension and an unfolded size dimension, you must carefully select the one that fits your requirements under a folded size for carrying. If you are looking for a hiking or backpacking solar charger, then you must also take a look at the unfolded size charger as it should not be bigger than the backpack you have. 

Charging Specs

Another important aspect is related to the charging options that you have. Some solar chargers are only suitable for USB devices, some will have two charging outputs while others will have three and maybe four charging outputs. This is important to consider depending on your requirements related to the number of electronics that you want to get covered with solar. 

You must also keep in mind that not all solar chargers are capable of charging a laptop. An 18VDC output must be available for this purpose and you must be careful in choosing a solar charger with the right connector for your laptop. Also, evaluating the electrical output of each USB or DC port is important to compare with the required input for your electronic device, for optimum charging, the required input should be lower than the actual electrical output of each USB port.

Conclusion

Solar chargers are the most valuable gadgets that you can have in whichever outdoor activity you are involved in, choosing one or another is highly dependent on the type of activity. For instance, features like portability are crucial for backpacking and hiking activities, while others like power output are more important for camping and picnics. Meanwhile, waterproof ratings are deeply necessary for fishing and sailing activities.

We have evaluated some of the most remarkable solar chargers in the market, mostly all of them are located between 10W and 60W with efficiency values between 20% and 25%. Features such as waterproof ratings, loops, anti-scratch covers, weight and sizes, ammeters and others are always valuable to consider when selecting solar chargers. With these tips and evaluating the activity that you will be performing, you will be able to select the most accurate solar charger for you.
