1. Anker PowerPort Solar Lite 21W - Best Overall
The Anker PowerPort Solar Lite delivers 21 watts of power through a dual‑panel design that tracks the sun for optimal angle. It features a rugged, water‑resistant PET coating and a built‑in kickstand, making it easy to set up on a backpack or a flat surface. The charger supports both USB‑C Power Delivery (up to 18W) and a standard USB‑A port (up to 5V/2.4A), allowing you to charge a smartphone and a small tablet simultaneously. In real‑world testing it reached 50% charge on a typical smartphone in about 2.5 hours of direct sunlight.
2. RAVPower 24W Solar Charger - Best Budget
RAVPower’s 24W model packs three high‑efficiency SunPower cells into a lightweight, foldable sheet that weighs just 350 g. It offers two USB‑A ports with smart IC technology that automatically identifies the connected device and provides the fastest safe charge. The panel is built with a silicone‑coated fabric that resists tears and moisture, ideal for rugged outdoor use. At peak sun it can deliver up to 2.4 A per port, enough to fully charge most smartphones in under three hours.
3. Nekteck 21W Solar Panel - Best for Portability
The Nekteck 21W charger uses a single high‑efficiency monocrystalline cell that folds into a compact 6‑inch rectangle when not in use. It includes a built‑in cable management clip and a rugged PET cover that protects against scratches and light rain. The device provides a single USB‑C port with Power Delivery up to 18W, which is perfect for newer smartphones that support fast charging. Its lightweight design (under 300 g) makes it a favorite for backpackers who need minimal bulk.
4. Blavor Solar Power Bank 20000mAh - Best Integrated Battery
Blavor combines a 20,000 mAh lithium‑polymer battery with a 5W solar panel, offering a dual solution for days when sunlight is scarce. The power bank includes two USB‑A ports (5V/2.4A each) and a USB‑C input/output that supports 18W Power Delivery. Its rugged silicone shell is drop‑tested to 1.5 m and features an LED flashlight for emergency situations. While the solar input is modest, the large internal battery can fully recharge most phones three times on a single charge.
5. AUKEY 10W Solar Charger - Best for City Use
AUKEY’s 10W charger is designed for commuters and short trips. It folds into a thin, pocket‑size rectangle and uses a single high‑efficiency cell that delivers up to 2.4 A on a sunny day. The unit includes a built‑in USB‑C port with 18W Power Delivery and a USB‑A port for older devices. Its matte finish resists fingerprints, and the integrated carabiner lets you attach it to a bag or bike frame. Though its output is lower than the larger panels, it is an excellent low‑cost option for daily carry.
How to Choose
When selecting a solar phone charger, start by evaluating the amount of sunlight you expect to encounter. Panels with higher wattage and multiple cells generate more power in direct sun, but they also add weight and bulk. If you travel light, a single‑cell foldable panel or a solar power bank may be more convenient.
Next, look at the output ports. Modern phones often use USB‑C Power Delivery for fast charging, so a charger that includes a USB‑C PD port will keep your device topped up quickly. For older devices, a standard USB‑A port with smart IC technology is sufficient. Finally, consider durability: water‑resistant coatings, reinforced hinges, and drop‑tested housings are essential if you plan to use the charger in rugged environments.
Frequently asked questions
Can solar chargers work on cloudy days?+
Yes, they generate power under diffuse light, but output drops to about 30-40% of full sun, so charge times are longer.
Do I need a special cable for these chargers?+
Most models include a USB‑C or micro‑USB cable, but using the cable that came with your phone ensures optimal charging speed.
