But for the price and features, the FEELLE Portable Solar Power Bank is well-deserved as our pick for runner-up.
The highly efficient Renogy E.FLEX 21 Portable Solar Panel provides best-in-class charging speeds. Three large solar panels provide an impressive 22% to 25% energy conversion rate and clock out at 21 watts. Two USB outputs allow charging to multiple batteries or devices at once.

A built-in kickstand allows optimal positioning, and its efficient design makes it small enough to strap to a bag for charging on-the-go. An integrated USB port charges phones, external battery banks, and other small devices.
Why Buy: Goal Zero has established itself as a leader in portable solar solutions. While it’s not the largest portable solar panel out there, the Goal Zero Nomad 10 Foldable Solar Panel hits the sweet spot between portability, versatility and capacity. If you need relatively fast charging for small electronics on your next outdoor adventure, this is the panel for you.
For a budget option, we’ve placed the Blavor 10000mAh Solar Power Bank as our top pick. The generous battery capacity is enough for multiple cell phone charges, and the solar panel offers trickle charging when the sun is shining. A useful dual LED flashlight, compass and Qi wireless charging make the Blavor 10000mAh Solar Power Bank an attractive solar phone charger.
Why Buy: While not the fastest solar charger out there, the Blavor 10000mAh Solar Power Bank is a steady performer nonetheless. Whether charging from a wall or trickle charging with the solar panel, the Blavor 10000mAh Solar Power Bank is loaded with impressive features you might not expect at this price point.
For those looking for a sun-powered adventure, the heart of a solar phone charger is the solar panel itself, which works exactly the same way as a larger rooftop panel does.
Solar panels convert the energy of photons (light particles) into electricity, a process called the photovoltaic effect. When a photon hits a solar panel, its energy causes electrons to flow throughout the solar cells, producing an electric current to charge devices or batteries.
All solar panels produce direct current (DC) energy, which can be used to charge small battery-powered devices like cell phones and computers. Solar panels for homes and businesses must be converted to alternating current (AC), which requires an inverter.
Lack of inverters and small panel sizes make solar phone chargers a compact and efficient way to charge DC electronics.
Just like there are different types of solar panels for homes, there are different types of solar phone chargers.
Standalone panels: These solar phone chargers consist of one or more panels with built-in charge ports (usually USB ports). They’re great if you need a large amount of energy for quick charging or powering larger devices. The downside to standalone panels is that they lack integrated batteries, so you can only charge your devices when the panels are in direct sunlight. They also tend to be on the large side. But if you need more power than a smaller charger can provide, standalone panels are the best option.
Solar battery banks: Solar chargers with a built-in battery are handy for carrying a reliable, portable charge wherever you go. The most common variants include a small solar panel atop a battery, but some options include fold-out panels for better capacity and faster charging. Aside from some notable exceptions, most solar battery banks take days to fully charge via sunshine alone, and almost none of them will charge your cell phone and the internal battery simultaneously. If you prioritize a rechargeable battery with solar backup, solar battery banks are a good option.
Solar phone charger costs vary depending on type, capacity, quality and features. The best solar phone chargers balance quality, performance and price, ranging from $30 for basic solar battery bank chargers to $150 for standalone solar phone charger kits.
Now that you know how solar panels work to charge your phone and some of the best solar phone charger models available, you may be wondering how to narrow down the right product for you. Here are some things to consider when making your purchase:
You’ll probably want to take your solar phone charger on the go, so think about the following:
In addition, look for other features that might come in handy, such as:
Keep in mind that the greater the number of features, the larger (and sometimes more expensive) the unit will be.
How much power a unit can produce and store may be the most important factor to consider when buying a solar cell phone charger. A high-amperage battery will provide more charges for your devices but will take more solar input to charge. If you’re going to rely on the sun to provide all of your power, prioritize high-output solar panels capable of quickly charging your electronics. If you just need a high-capacity battery with the option for solar trickle charging, a smaller solar battery bank could be a good fit.
Because they’re portable, choose a durable solar-powered phone charger to stand up to the wear-and-tear of travelling and outdoor activity. The best solar phone chargers are rugged and dependable, featuring weather-sealing and robust construction.
All solar phone chargers are portable, at least in the technical sense. But there are degrees of portability depending on your needs. Ranging from somewhat heavy multi-panels requiring stationary placement to simple units you can strap to your pack, there’s a unit for everyone, from trail runners to off-grid nomads. Just remember that with greater portability often comes sacrifice in other features, especially panel output.
Many solar chargers for phones feature more than just charging, with integrated LED flashlights, backup batteries, charge indicators, carabiners, compass straps and more. While these can be nice, don’t let extra features distract from what really matters: Staying powered when you need it most.
Finally, there’s cost. While none of our top picks will break the bank, some are undoubtedly pricier than others. It’s best to save up for a costlier unit if you absolutely need its functions, but if you only need a battery with solar backup, there are plenty of budget-friendly options out there.
Solar phone chargers are great for powering devices in off-grid situations. They can be used over and over again without having to be plugged into an outlet to recharge like standard battery banks.
The time it takes to charge a phone with a solar charger will depend on the output of the battery and the amperage of your phone’s battery. Some battery chargers can fully charge a phone in as little as 90 minutes, but others may take up to four hours.
We rated the Renogy E.POWER Portable Solar Charger and FEELLE Portable Solar Power Bank as our top two picks for the best solar power chargers. These models are rugged and dependable enough to charge your devices anywhere you go.
Key factors to consider when choosing a solar cell phone charger include design features like number of charge ports, size/weight, power output, durability, portability, extra features, and cost.
