1. SOS Solar Phone Charger – Best Overall

If you want the most reliable, all-in-one solar power bank, the SOS Solar Phone Charger is our top pick for 2025.

Key Features:

• 20,000 mAh battery — enough to charge most phones 6–8 times
• Dual USB ports + wireless charging pad for multiple devices
• IPX7 waterproof and dustproof casing — ready for rain or splashes
• Dual LED flashlight with SOS mode for emergencies

Why We Recommend It:
While standard solar chargers operate only in direct sunlight, this model saves power in its heavy-duty battery, so you can power devices anytime, day or night. Its durable construction makes it ideal for camping, hiking, or emergency packs.

Tip: Charge it through USB first, then top it off using the solar panel. This provides maximum power availability.

2. Anker PowerPort Solar 24W – Best for Panel Efficiency

Capacity: N/A (panel alone)
Why We Love It: Super-fast, collapsible solar panels that can power 2 devices simultaneously.

Perfect for travelers and hikers, this solar panel is incredibly efficient even under indirect sun. But since it lacks an internal battery, it functions optimally when combined with a power bank.

How to Select the Best Solar Phone Charger

In buying a solar phone charger in 2025, keep the following in mind:
