    Solar chargers are built for outdoor usage, and they are powered with the help of sunlight. While choosing the best solar charger for your needs, analyzing the solar panel size, charging speed, battery size, and the number of ports is essential. Watt and watt-hour should be considered to narrow your research and purchase the best solar panels.

    What Are Watt And Watt Hours?

    A watt is a power unit that measures the energy transfer rate. In electrical terms, the watt is the rate of electrical work done by a device during appliance powering.

    The simple formula of watt is equivalent to volt-ampere. Here is how to calculate it:

    Power is the energy rate at which energy is consumed or generated; hence, it is measured in watts. Meanwhile, watt-hour is the rate at which one-watt power is consumed in one hour. Here is the formula to calculate the watt-hours of any device.

    Watt-Hours = Total Number Of Watts Total Number Of Hours

    Battery Capacity of Phones

    Generally, a solar phone charger that can supply 10 watts is sufficient to charge a smartphone for one day. Many solar power panels have robust battery protection systems, so you can power all your devices safely.

    For instance, if you know the battery capacity (mAh) and volt (V), you can easily calculate the watt-hour.

    Formula is (mAh) (V) /1000 = Wh.

    Suppose the battery capacity of the solar power charger is 300 mAh, and the volt is 5V. Here is how to measure watt-hours.

    Watt-hour = 300 mAh 5V / 1000 = 1.5 Wh.

    Here is the breakdown of the estimated solar power needed daily to charge different types of smartphones.

    Customer Reviews

    I bought this for dry camping in my RV. I wanted an easy way to recharge my multiple Ipads, iPhones, and computers. I just returned from an 18-day trip, and the Jackery 500 with the 100-watt solar panel performed flawlessly. Recharging it was the easiest system I have ever worked with. In sunny AZ, the system went from 83% to 100% in 2 hours. If it was cloudy, I plugged into my 12-volt plug while driving and generally went from the low 80s to 100% within a 3-hour drive. I have not used the 120-volt charger yet as it was not needed. In total, I recharged 2 Ipads, 2 phones, 1 computer, and 1 jet pack overnight. The battery would be in the low 80% by morning, sometimes 75% by evening back to 100%. I highly recommend this system.

    Jackery 500 gave me a lot of power for 7 days of camping. It powered my Alpicool ref, USB lights, cell phone, etc. The lowest power I had overnight was 87% until I could charge my solar panel the next day. I highly recommend this. I will use my CPAP on my next trip and trust it will give me power all night. I used Goal Zero before. I was not impressed, and Jackery’s price is more reasonable. Buying expensive things like goal zero does not prove great performance but is overrated as a waste of money. Go for Jackery. It is also lightweight.Maria

    What Size Solar Charger For a Phone Do I Need?

    Solar cell phone chargers come in different sizes, shapes, and types. The simple rule to purchasing a solar panel is understanding its compatibility with your device.

    Calculate the size of the solar charger for a phone with this formula:

    Working time = Watt-hour of the solar power station 0.85 / operating wattage of your device.

    For instance, if we assume that the cell phone consumes 10 watts and the watt-hour of the solar power station is 167Wh, the working time will be 167 Wh 0.85 / 10 = 14.2 hours.

    Purchasing a solar power station with a 167 Wh battery capacity can charge a phone at 13 Wh capacity 11 times. You can calculate the number of charges a solar panel supports with a simple formula:

    The number of charges supported = 0.85 Power station capacity/phone capacity.

    Depending on the requirements and phone capacity, you can determine the size of solar panels you’ll need.

    How do solar cell phone chargers work?

    Having just spent a month (yes, a whole month!) with my family over Christmas (there was at least 11 of us at any given time sleeping and eating there), I have come to appreciate the need for an alternative method to charge my cell phone.

    Trying to find a plug that was not already occupied by other cell phones, tablets, computers, and ipods charging was next to impossible.

    This predicament led me to the pressing need to investigate an alternate means of charging my cell phone.

    I knew solar charges were a great option, as I was pretty sure I could find a free windowsill somewhere in the house.

    However, I did not know much about them or which one was right for my particular situation. So, I researched it, and this article is the result of my findings.

    I found this information extremely useful when ultimately picking out my solar charger and I am confident you will too.

    How solar chargers function

    A solar charger consists of three parts:

    Solar Panel

    The solar panel is made up of photovoltaic (PV) cells. These cells contain light-sensitive materials that convert sunlight into small amounts of electrical current.

    When sunlight shines onto the solar panel, the resulting electricity is sent to the battery, which is regulated by the charge controller. The sunlight can be direct, or indirect.

    Rechargeable Battery

    A solar charger can recharge the following types of batteries:

    The battery stores the electricity generated by the solar panel for later use by any electrical devices that are connected to it.

    This stored energy is available to use at any time, including at night.

    Charge Controller

    A charge controller regulates the amount of voltage delivered from the battery to the device it is connected to.

    How to charge the charger

    It’s simple, just like Ron Popeil says, ‘Set it and forget it!’

    • point the solar panel towards the sun at a 90-degree angle
    • while the charger is capable of charging in partially-cloudy conditions, full sunlight is ideal for a quicker charge

    Literally, this is all you have to do to charge your solar charger.

    How well do they charge?

    How well a solar charger recharges your device depends on the weather.

    When recharging your solar battery on a sunny day, with no Cloud interruptions, it will recharge much quicker and efficiently than on a cloudy overcast day.

    It takes around 3 hours to fully recharge a solar battery (this is dependent on the size of the battery).

    This means that on a sunny day, you will be able to recharge your device quicker than on a cloudy day because your battery would have charged quicker. Makes sense, right?

    When a solar battery is completely recharged, it will take around 10 hours to fully recharge your cell phone.

    how long do solar chargers last?

    Solar chargers generally last around 300-400 charges. So the life expectancy of your charger will depend on how often it is used.

    Limitations

    How to choose the right one for you

    There are many different types of solar cell phone charges available to you. Picking the right one for your particular use will ensure you have the best experience as possible.

    Home use

    Picking a solar charger for home use is not as easy as it sounds. While solar technology keeps getting better and better, the solar panel collects sun rays more efficiently from direct sunlight, not indirectly through a pane of glass.

    That being said, there are some solar chargers that are designed to stick in Windows, just be aware that they will not charge as fast or be as powerful as most directly charged batteries.

    This solar window charger sticks right to the window using suction cups. It’s small and perfect for leaving in the window while your phone charges on the windowsill.

    One major drawback of this charger is that at only 1800mAH, it may not be able to charge your phone completely with a fully charged battery.

    Another window option is GreenLighting Solar Phone Charger, at 6000 mAH it boasts being able to charge your cell phone up to 1% per minute until it is fully charged.

    It uses a lithium-ion battery, and is pretty small, so it won’t obstruct a window view too much.

    With one large suction cup, you can leave it in a window at home and use it whenever your phone requires a charge.

    In the Car

    The same issue arises with in-the-car solar charging as at-home solar charging. Solar panels are less efficient when charging a battery from indirect sunlight.

    So again, please keep in mind that when charging your battery through a pane of glass, it will not be as fast as charging it with sunlight directly.

    Both solar charges mentioned above will work in the car as well, as they use suction cups to stick to the glass so they are not permanently fixed.

    Outdoors

    This is where solar chargers shine!

    Beautiful, direct sunlight is the solar panels jam.

    For outdoor activities such as hiking, backpacking, walking, jogging, rock climbing, or anything else you might get up to in the great outdoors, there are a few characteristics and features to look for in a solar charger.

    • battery type
    • size
    • weight
    • durability
    • water resistance
    • ability to charge with an overcast sky

    Troubleshooting

    If your solar charger is not charging your phone to a full charge, here are a couple basic reasons why.

    • Weather: a cloudy day could result in the rechargeable battery unable to receive a full charge, thereby rendering it unable to fully charge your device
    • Indirect sunlight: charging through a window pane may result in inefficient charging of the solar battery, similar to a cloudy day
    • Weak rechargeable battery: the solar battery may not be strong enough to charge your phone fully even when the solar battery itself is fully charged

    In order to avoid these common issues:

    • charge your solar battery with direct sunlight as much as possible
    • make sure you buy a solar charger that is strong enough to fully charge your device

    Solar-Powered Phone Chargers: Mobile Access to Those Off-Grid

    The Little Sun Charge, a solar­-powered phone charger, is finding success on Kickstarter. The project was launched as a part of the Sustainable Energy for All Initiative (SE4All), originated by UN Secretary-General Ban Ki-Moon, which aims to ensure global access to modern energy services by 2030.

    The Little Sun Charge is powered entirely by solar power and charges phones in less than five hours. Other conventional solar-powered phone chargers require between eight and twenty hours to charge a phone. The device is barely larger than a smartphone and uses a USB port, so it can power other electronic devices as well.

    While marketed on Kickstarter for travelers, hikers, campers and freelancers, Little Sun Charge has particular relevance for those who live off-grid. With this device, phone ownership is a greater possibility, as those individuals could have a means to power their phone. Currently, 1.1 billion people live without access to electricity.

    The project was initiated by Danish-Icelandic artist Olafur Eliasson and Danish entrepreneur and engineer Frederic Ottesen.

    The Kickstarter project has a fundraising goal of 50,000 Euros by the end of September; it is currently at 40,000 Euros and is expected to meet its goal. Proceeds from the project go towards support solar power initiatives in Africa and the SE4All Initiative.

    Little Sun Charge is the second Little Sun project; the first was an LED lamp. 200,000 of these Little Sun LED lamps have been distributed in Europe, Canada, Australia, Japan and the United states in addition to 10 African countries, including Zimbabwe, Ghana, Senegal, Ethiopia and Kenya.

    Both devices aim to support sustainable energy initiatives in Africa, especially solar entrepreneurship.

    The charger is expected to be released in March 2016 at a retail price of 120 Euros. ­
