Best Solar Chargers: Top Picks and Recommendations?

I. Features and functionality

Solar chargers correspond of photovoltaic panels that convert sun into electricity through the photovoltaic effect. It's a new high- tech solar series product with intelligent adaptation function that can acclimate different affair voltages and currents. It can charge different charging products, adjust the voltage from 3.7 -6V, and can charge MP3, MP4, PDA, digital cameras, mobile phones and other products. With five high-brightness 5LEDs, it can be used for daily lighting and emergency lighting! It also has the advantages of small size, high capacity and long service life. It is suitable for backup power supply and emergency lighting in environments such as business trips, tourism, long-distance boat rides, field operations and students. It has safety protection, good compatibility, large capacity and small size. , long service life and high cost performance.

 

II. Function parameter

Solar panel specifications: 5.5V/70mA

 

1. High capacity rechargeable battery: 1300MAH

 

2. Output voltage: voltage is 5.5V

 

3. Output current: 300-550mA

 

4. The time it takes for the charger to charge the mobile phone: about 120 minutes (there are slight differences in different brands and models of mobile phones)

 

5. Solar charging time for the built-in battery of the charger: 10 to 15 hours

 

6. Use a computer or AC adapter to charge the built-in battery of the charger. Time: 5 hours

 

 

III. Advantages and disadvantages

Advantages:

1.usage efficiency. Usage efficiency covers two aspects: the conversion efficiency of solar panels and the secondary conversion efficiency. The conversion effectiveness of solar panels, as the name suggests, refers to the effectiveness of converting light energy into electrical energy; while the secondary conversion effectiveness refers to the effectiveness of storing light energy in batteries after being converted into electrical energy.

 

2.the quality and capacity of the battery. The battery capacity is generally 1.2 times that of your mobile phone battery. When the built-in lithium battery of solar energy is discharged into digital products such as mobile phones, there will be energy loss during the energy conversion process. The conversion rate is generally 80%-90%. Only the electricity generated by solar energy can be enough for your mobile phone. Only such a large battery can save your energy. The cell phone battery is fully charged. The quality of the battery is also related to the service life of the solar charger.

 

3. renewable and sustainable energy. druggies will be suitable to take advantage of free and abundant sun to power their bias. Solar chargers are independent of the grid and are particularly useful in out- grid or remote areas where power is limited.

 

Disadvantages:

1.the control circuit and protection circuit. The current solar cell phone charger products on the market are very complex. The protection circuit and control circuit inside them may be simple in design or have poor compatibility, which may easily damage the cell phone or shorten the service life of the cell phone and battery. Therefore, the design of control circuit and protection circuit is very important.

 

2.solar charger accessories. This issue is often overlooked by many users, but it is an aspect that cannot be ignored. There are unscrupulous suppliers on the market that configure inferior accessories for price advantage, such as AC chargers (commonly known as Fire Ox). AC chargers are available with or without IC protection circuits. AC chargers without protection ICs not only have low charging current, but also have long charging times and are ineffective, thus posing potential safety hazards. When purchasing a solar charger, you should pay special attention to whether the AC charger has circuit IC protection.

 

3. the impact of weather. Cloudy or cloudy days can reduce the efficiency and charging speed of solar panels, thereby prolonging charging times.

 

 

IV. Applications and considerations for solar chargers

Solar chargers are suitable for a variety of scripts, including out-of-door adventures, exigency preparedness accoutrements , off- grid living and sustainable energy results. They're generally used to charge smartphones, tablets, GPS bias, cameras, and other movable electronics while on the go. still, it should be noted that solar cell phone dishes can only be used in extremities and can not be reckoned upon to charge mobile phones and other digital products. To completely charge mobile phones, general mobile phones require a solar cell phone charger with a solar panel greater than 0.7W. 

 

V. Notice

1. Do not charge intermittently under strong light (direct sunlight on the solar panel). It takes about 8 hours to fully charge the built-in battery.

 

2. Do not place the charger in the car during summer (the temperature inside the car is too high). Affects battery life

 

3. Do not charge this charger through glass. Charging effect is poor.

 

4. It must be charged under strong light. Turning on the light under weak light (Light1) only means that light is detected, but does not mean that it is charging (such as under indoor lighting). So please do not charge in low light.

 

5. Since the power contained in each charger is not consistent when leaving the factory, the charging or discharging time will be different for the first time.

 

6. Do not use corrosive solutions to wipe the machine to avoid damaging the product.

 

7. It is strictly prohibited to throw this product into fire to avoid causing an explosion.

 

VI. Conclusion

In conclusion, after the above data and evaluation, solar chargers are not the first choice for other occasions where fast charging is required. However, for some outdoor occasions or places where solar energy is abundant, a suitable solar charger can be recommended. Users can utilise sustainable energy to keep their devices continuously powered while reducing the impact on the environment.

 

FAQ

1. Are solar chargers really useful?

Yes, solar chargers are particularly useful for some outdoor occasions, especially where there is a power cut, but only if there is enough light.

 

2. Where can I buy a solar charger?

You need to buy the right solar charger according to your needs. There are many shops selling solar chargers online, and a quality-assured shop is the key to prefer. For more information on what you need to know visit www.blikai.com.

 

3. How long does a solar phone charger take to charge?

Depending on the capacity of the solar charger, the charging time also varies. It usually takes a few hours.
