Charging your phone with solar power is a sustainable and convenient way to stay connected, whether hiking, camping, or dealing with a power outage. There are multiple ways to harness the sun’s energy to keep you powered up, from simple solar panels, also called photovoltaics, to advanced solar generators.
Each option has unique advantages and drawbacks, so you must choose the right solution for your specific needs.
We will explore each method, how it works, and its advantages and disadvantages. Now, let’s dive in so you can go on your next adventure using clean energy from the sun to keep your devices going!
Can You Charge Your Phone With Solar Power?
Absolutely. There are plenty of ways to charge your phone with solar energy, allowing you to recharge while camping or hiking. There are setups with direct connections to a photovoltaic panel, a portable power pack with built-in photovoltaics, and portable EcoFlow Solar Generators for faster and more reliable charging speeds.
Your chosen method depends entirely on how you want to use it, if you have other devices that also need charging, and how much time you have to wait.
3 Ways to Charge a Phone With a Solar Panel
There are multiple ways to charge phones using photovoltaics, and which option you choose mainly depends on how you want to use it and your energy needs. Let’s examine the three most common methods, how they work, and their advantages and disadvantages.
Direct From Solar Panel
You can recharge phones directly from a small portable photovoltaic panel via a 12V cigarette lighter plug adapter, or there may be USB ports you can use directly or with another adapter. However, there are a couple of drawbacks to this method. The obvious one is that it will only charge when sitting directly in the sun, so it won’t work at night or in bad weather.
Another issue is that phones will only charge so much at a time, usually taking several hours under optimal conditions, and a larger panel typically won’t give faster charging speeds. Furthermore, some phones won’t allow a trickle charge and need a full 120mAh before they start charging, so if your output isn’t high enough, it just won’t work.
Finally, if a cloud passes and the output drops, even when the sun returns, some phones need to be manually reset before they start charging again. This is where using an EcoFlow RIVER 2 Series Photovoltaic Generator excels. They pack plenty of power to get you at full capacity fast and have enough to power other things as well.
You can use the photovoltaic panels to quickly recharge the generator’s battery and store it so you can still have energy at night or on a cloudy or rainy day and not be at the whims of the weather.
Portable Power Pack With Solar
A portable power pack is a small, compact battery unit a bit larger than your phone. It’s simply a small battery with a built-in photovoltaic panel to recharge it. Some models are rugged and durable for outdoor use and great for day hikes. However, be careful, as they come in various capacities.
Some may not even get your device to full capacity, while others will have a large enough battery to give you a couple of recharges. However, the major drawback of these units is that the photovoltaics are very small, and some devices can take days to recharge their batteries, especially if you don’t have access to full direct sun all day.
So, these aren’t your best options if you are off-grid or have higher power needs.
Those with higher power needs or on multi-day adventures will be far better off with the EcoFlow RIVER 2 Max + 160W Solar Panel. It’s still compact and lightweight enough to fit in your backpack, along with the 160W photovoltaic panel. Still, it gives multiple fast phone recharges and still has enough power to run other devices. The photovoltaic panel it comes in will recharge its powerful battery in just 3 hours under optimal conditions.
Solar Generators
The solar generator is the best portable photovoltaic charging method for most situations. It will give you the fastest phone charging capabilities. The generator also recharges quickly using photovoltaic panels since they are designed to take in energy much quicker than phones.
The EcoFlow RIVER 2 Pro Solar Generator (PV220W) is the perfect travel companion but also works great at home during power outages. It has a super-efficient 220W portable photovoltaic panel that generates power from both sides, giving it the industry’s best efficiency ratings.
Your EcoFlow RIVER 2 Pro has an impressive 768Wh capacity but only weighs about 7.8kg (17.2lbs). With that much power, you can use them for many other things, including your laptop, lights, and even small kitchen appliances, whether on a road trip or at home. You can even bring it fishing to run your GPS and fish finders or small appliances on a boat.
It’s also compact and lightweight enough to fit inside a backpack for hiking or to use inside your tent when camping. However, if you plan to fly with it, you must bring all batteries in your carry-on luggage, as airlines do not allow batteries in checked baggage.
Frequently Asked Questions
A single photovoltaic panel as small as 10–15 watts will charge a phone. However, it can take many hours, and your charge may drop to nearly zero if a cloud passes. Larger panels won’t necessarily charge it faster as the phone has its own limits. This is why photovoltaic generators are the best option.
If you are charging directly from a panel to your phone, it depends on the panel’s wattage, the phone’s battery, and the weather conditions. However, even under ideal conditions, it can take several hours. Using a photovoltaic generator is a much faster option.
Some phones won’t take a slow charge, requiring a minimum of 120mAh before charging. Also, cloudy days can reduce your charge to near zero, and some phones must be reset each time this happens.
Final Thoughts
Harnessing energy from the sun to charge your devices is not only eco-friendly but also incredibly practical for off-grid adventurers and emergency preparedness. Direct solar panel connections and portable power packs work for light usage and for those waiting for their slow charge.
However, photovoltaic generators like the EcoFlow RIVER 2 Pro Solar Generator (PV220W) offer superior reliability, charging speeds, and versatility for those needing a faster and more powerful option. Whether camping, hiking, or at home during a power outage, photovoltaic generators ensure you have dependable power when you need it most.
