    How does a portable solar laptop charger work?

    You have two choices when using a portable solar charger for laptops. One, hook up the laptop directly with the solar panel, or two, include a power bank in the setup.

    Direct use

    Solar chargers for laptops come with an 18V output port. Plugin one end of the correct adapter to the 18V DC port in the solar laptop charger and the other end to your laptop. Do note that for a select few laptops, you need to use only recommended adapters and not standard ones.

    Now you need to place the portable solar panel out in the sun for it to generate solar energy. And, your laptop starts charging! It is as simple as that!

    In this arrangement, the sun should be shining, the solar panel charging, and the adapter plugged in for the charging to happen. When you want to charge the laptop battery and the sun is not shining, this method won’t work. You can still use a solar laptop charger to charge laptop if you add a power bank or solar generator to the array.

    Using a power bank

    In this instance, you connect the adapter to the power bank and not to the laptop directly. Once the power bank is charged, you can plug in your laptop to the power bank to transfer the power. 

    The advantage of this arrangement is that you can keep the power bank charged when the sun is shining and use the battery charge to charge your laptop battery whenever you need. This can be especially useful for charging during night hours.

    Another benefit of using a power bank or solar generator is that you can use 12V solar chargers for charging power banks. 12V solar chargers are more popular and you will find more choices in the market.

    Tips for buying solar chargers for laptops

    • Make sure that the voltage is correct. You will find this information on the laptop adapter. 
    • When using it directly, you need an 18V solar charger and with power banks, a 12V one would be good enough. Again, check the voltage requirement of the power bank or solar generator.
    • Using a solar charger or power bank with a voltage rating higher than that of the laptop adapter can harm the laptop. Less voltage rating will not damage the laptop but your device will not charge.
    • The current or amps is also important. The amps of the solar panel and your laptop adapter should match though higher amps will not end up damaging the device as long as the voltage rating is a match. However, it is desirable for the long life of the device, if you use a solar charger with a matching amp rating.
    • A lower amp rating again will not pose any problems but may be insufficient to charge laptop.
    • You need 3-5 amps and 18-20 volts to charge a laptop. This means the wattage of the solar panel should be in the range of 50-100 watts. 
    • The size of connectors differs for different brands of laptops. Make sure that they match the laptop specifications. Most solar chargers come with connectors suitable for all major brands.
    • Reverse polarity protection is desirable in solar chargers for laptops. At night when the solar panel is not producing solar energy, it may end up discharging or draining the laptop battery instead of charging it. A blocking diode can prevent this reverse flow of energy. 

    Are there any downsides to charging laptops with solar chargers?

    Solar panels are well known for their abysmal levels of efficiency. For a portable solar charger, the best you can expect is 30%. This means the panels can absorb only 30% of the sunlight falling on them, while the rest is wasted away. This means the laptop may need 12-30 hours to reach full charge.

    The hassle with the low efficiency is that when the sunlight is not bright enough, the voltage will drop and the laptop won’t charge. To charge devices like a phone, this would be enough but for laptop charging, you need the sun shining brightly directly above the panel.

    You can compensate for the low efficiency of solar technology by adding more solar panels. But it will rob the arrangement of its portability.

    Due to the changing intensity of sunlight, you may experience voltage and current fluctuations in the solar charger. Because of this, your laptop may end up not charging. You may not be even aware of this if you leave the laptop plugged in without monitoring it.

    However, you can avoid all these troubles by charging using a power bank. Power banks are designed for higher voltage and current variations and they can charge even with limited sunlight. You can use the charge in the power bank to charge your laptop or any other electronic device when needed.

    You can also consider a power station, the big brother of power banks. It is much more than a battery and consists of an inverter and a charge controller. 

    Bottom line

    As the capacity and features vary, the price of these solar panels also goes up. Ultimately, it is your requirement that decides the perfect solar laptop charger for you. You need to decide whether you want a minimalist solar panel for charging your laptop or a higher capacity one that can supply solar power to your other electronic devices.

    You should consider affordability, portability, durability, capacity, warranty, and review/ratings before making up your mind about the solar laptop charger.
