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.

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 to Build a Solar Charging Station Anywhere
One of the most amazing innovations in the last five years has not been a new invention as the perfection of existing technology. Solar panels, which were once the territory of only the very rich and very environmentally dedicated, have gotten smaller, more efficient, and more affordable, and you don’t even need to mount them on your roof. Many people still think that solar is in the realm of “Go Big or Go Home,” but we’re here to tell you that times have changed.
Building a Solar Charging Station
While you can start your adventures into solar power generation with a full rooftop-mounted and grid-connected installation, you can actually learn about solar and build yourself a disaster-ready power generation and charging station for less than 500 and a little elbow grease. With this simple and easy to connect contraption, you’ll be able to generate enough power to slowly charge an electric vehicle or keep several mobile devices powered for as long as the equipment lasts.
What You’ll Need
Building a solar charging station is surprisingly simple because the components are now very efficient. All you need is power generation, power conversion, power storage, and the cables in between. All the parts can be bought on Amazon from various manufacturers, so compare and amperage until you find the right combination for your budget and power generation needs.
- Portable Solar Panels
- You don’t need a professional to affix some weather-resistant solar panels to a sunny spot and draw power. You don’t even need a stable location. Portable solar panels can be mounted, unmounted, and moved at any time, wherever you happen to need solar power.
- Solar Cables – One Red, One Black
- These will connect the solar panels (which have matching leads) to the solar controller and inverter, which will regulate the energy from the solar panels and make them useful.
- Solar Controller
- The solar controller device is part of what makes solar power so much more accessible than it used to be. It’s essentially a specialized charge controller with a useful info display screen.
- The inverter is what turns the DC solar energy into AC device and appliance energy. They usually have at least one power socket and often have USB ports as well. Some inverters come with their own batteries.
- A deep supply of battery storage ensures that you don’t waste solar power and have plenty to last you through the night and on rainy days.
- Battery Cables – One Red, One Black Per Battery
- These will connect the batteries and the solar controller, allowing the controller to balance voltage between, serve power out of them, and prevent them from over-draining.
Choose Your Structure
You can build your solar charging station on anything you want. For an electric car charge stop, you can put the panels on top of a carport and stow the rest of the equipment safely in a cabinet within. You can add them to a camp cabin or tent to power basic equipment like a camp stove or radio. With flexible panels, you can even stick them securely but temporarily to the top of your car, truck, or RV with 3-5lbs Command strips for convenient mobile device charging on road trips. The Command strips don’t damage the paint when removed, so you can experiment freely without having to make even semi-permanent alterations. Choose what you’ll mount the solar panels on and how you’ll protect the electrical equipment before getting started.
Putting Together the Charging Station
Step 1: Mount the Solar Panels
For a semi-permanent structural mount like on a shed or carport, use a metal frame and bolts to attach the solar panels to the roof of your structure. Make sure to use the right brackets and screws based on the type of roof you’re working with. Tents should rely on either foldable solar panels or those with holes so they can be tied to the top or sides. A car either permanently mounts them with a frame or temporarily mounts them with safe sticky strips.
Step 2: Emplace the Batteries
The batteries need to be in a safe, dry, moderately temperature-controlled, and stable position. Anywhere indoors is usually fine, but they need to be carefully secured in a vehicle and probably carried in a sealed box for camping.
Step 3: Place the Solar Controller
You’ll want the solar controller somewhere safe but easy to read, as it will tell you how much energy is being generated, how much is being drained, and approximately how full your collection of batteries is. Make sure it’s accessible before wiring and arrange your connections around where the solar controller needs to be.
Step 4: Connect Everything
Connect your solar panels and the solar controller with the solar power cables using parallel or serial wiring based on your amperage and voltage needs, then do the same for the batteries. If you need a converter from the batteries to the power ports you plan to use, connect this to the solar controller and its own cables.
Enjoy All the Free Energy
The sun is the most renewable energy source available to us, and now you can collect buckets of free energy every day with a simple installation. Whether you’re charging mobile devices, an electric car, a camp stove, or experimenting with everything that can be plugged into solar energy, every amp you use is one you made for yourself without a drop of fossil fuel. Now you know a lot more about solar power, can create a useful amount of electricity from anywhere, and are one step closer to a casually off-grid home with the capability of generating all the energy you need to live comfortably.

In this guide, we’ll provide you with step-by-step methods on how to make a solar phone charger without hassle.
What are the Materials Needed for Creating Your Solar Powered Phone Charger
You can look for mini solar panels in nearby local stores that sell electronic or science materials and tools. Or, you can find most of the materials you’ll need for this DIY project online.
- Two mini solar panels (should be 3-Volt 20mA each)
- One large heat shrink tubing (4-inch)
- One cell phone charger
- One small heat shrink tubing (4-inch)
- One solder iron
- One Altoids tin case
- One double-sided tape (3-inch)
- One heat gun
- One solder (3-inch)
- One wire stripper
- 1 oz. Flux
Step-by-Step Guide on How to Make a Solar Phone Charger
Step 1: Cut the tubing and the wires.
The initial step is to get the two solar power panels and cut all four wires approximately an inch in length. From there, cut about ¼-inch of plastic off the edge of each wire using a wire stripper. In doing so, the copper wires will be exposed.
The copper wire that is exposed is referred to as the lead. Afterward, you should cut the mini shrink tubing into four equal parts. Each of them should be 1 inch; then, glide the mini heat shrink tubing into both black wires.
Step 2: Solder the leads of the solar panel.
Paint the leads using a toothpick and flux on the black wire from one solar panel. Do the same process with the red wire from the other solar panel. After that, place the two leads together, and from there, you may start soldering using the soldering iron and your solder.
Step 3: Heat-shrink the tubing.
Glide the mini heat shrink tubing over the soldered leads. Using the heat gun, gently heat the tubing for it to shrink.
Step 4: Cut the wire of your phone charger.
The next step is to cut the wire of your old charger to roughly 2.5-feet and take off about 2.5-inches of the exterior plastic from the loose edge. Then, you may now cut off approximately ¼-inch of the inner wires to form the leads.
Glide the entire length of the large heat shrink tubing into the primary wire, which you’ll utilize later.
Step 5: Flux, join, and heat-shrink the loose leads.
Take the primary wire and then glide a mini heat shrink tubing section into the red wire. With a toothpick, flux all the loose leads of the solar panel and the primary wire. From there, start soldering the red leads from the solar panels and primary wire together.
You may execute the same process for the black wires. Glide the heat shrink tubings over the soldered leads. To shrink the tubings, you’ll need to use a heat gun.
Step 6: Examine your mobile charger.
It is now time to examine your cellphone charger. To do this, connect it to a cellphone under bright light.
Step 7: Heat-shrink the leads of the solar panels.
For this step, pick up your primary wire and then glide the large heat shrink tubing over the two soldered leads linked to the solar panels. Shrink the tubing using a heat gun.
Step 8: Tape and seal.
At the rear section of your solar panels, using double-sided tape, cover the two brass rivets. This is to ensure that they won’t make contact with the Altoid tin. Afterward, tape the two solar panels situated on the inner lid of the tin.
Lastly, fold the primary wire together into the case and seal. Look for a sunny spot and start using your homemade solar cellphone charger.

Make your own Solar Mobile Charger
A solar panel converts solar energy into electrical energy. Solar mobile charger regulates this electrical energy such that it could be used to charge mobile phones. Read this article to know how to make a solar mobile charger at home.
Solar mobile charger
Solar mobile charger is a device which can charge mobile phones using solar radiation. Its major component is a compact solar panel. This solar panel traps solar energy and produces an output voltage. But, since the light radiations falling on the solar panel can vary, the output voltage becomes unstable. For charging a mobile phone, stable voltage is required. So, to make the output voltage stable and regulated, we use a voltage regulator circuit along with the solar panel.
Most of the mobile phones have computer connectivity via USB cable. USB port establishes 4 connection terminals. The connection terminals at the two extreme ends are the supply terminals. In a female USB connector (port via which we plug in USB devices to computer), these terminals carry 5V DC. When a mobile phone is connected to the USB port of a computer, it utilizes this 5V supply to recharge battery. This feature is used in a solar mobile charger. It converts and regulates solar energy to 5V DC and the output will be available through the female USB connector. To this connector, we can easily connect a mobile phone via data cable.
1)Solar panel 12V, 4W2)Voltage regulator IC 78053) 100uF, 25V capacitor4) 10uF, 25V capacitor5) 100nF capacitor6) USB female connector7) PCB8) Connecting wires9) Soldering accessories
All these components can be purchased from any electronic spare parts shop or online store.
Let’s start building
Solar panelFirst of all, take the solar panel. On its back side, we can see two connecting wires. One is in red colour and the other is in black. The red wire is the positive terminal and the black wire is the negative terminal. There is nothing much to do with the solar panel.
Voltage regulatorThe regulator circuit consists of the following components.
1) IC78052) 100uF3) 10uF4) 100nF
Regulator on PCB
Solder all the components on a PCB as shown in the circuit diagram. To test the regulator circuit, connect voltage between 8 V and 18V to the input of voltage regulator. Now, measure the output. The output should be constant and it can be any value between 4.75 V and 5.25V. If so, your circuit is working properly.
Next, we need to connect it to the USB port. This has to be done carefully
Solder the positive output wire of the voltage regulator to the USB’s positive. Similarly, connect the negative output of regulator to the negative of USB. The USB port must be fixed properly to the PCB. Next, connect the solar panel to the input of the voltage regulator (positive of solar panel to positive input of voltage regulator and negative of solar panel to negative input). Once everything is connected, measure the output voltage in open sun light. It should be around 5V. Now, connect your mobile phone and you will see it charging.
Once everything is done, fix the circuit properly on a plastic box. The solar panel should face the Sun.
