10 Best Solar Phone Chargers 2025 in the United States

The Power-Bank-Solar-Charger by Mregb offers a substantial battery capacity of 42800mAh, meaning it can charge your devices multiple times before needing a recharge. Its rugged design, featuring IP67 waterproof, drop-proof, and dust-proof properties, makes it highly durable and suitable for outdoor activities. The device also includes a super bright LED flashlight, which can be extremely useful during emergencies or outdoor adventures.

Compatibility with all USB devices and support for QC3.0 fast charging on compatible devices are notable advantages, making it a versatile option for various gadgets. While the solar panel is convenient for emergencies, it charges the power bank very slowly due to its reliance on sunlight, which can be inconsistent. For regular use, it's recommended to charge it using a standard power outlet. The charger is relatively portable given its high capacity, but its considerable battery size may make it a bit heavier and bulkier compared to lower-capacity alternatives. This power bank is excellent for those needing a reliable, rugged backup power source for outdoor use but might not be the best option if quick recharging via solar power is a priority.

The Hiluckey Solar Charger packs a punch with a substantial 25000mAh battery capacity, allowing it to charge a cell phone 6-8 times and a tablet around 2.5 times. This makes it ideal for extended trips where access to electricity might be limited. The device features four solar panels, boosting the solar panel efficiency and offering up to 6W in direct sunlight, which is quite beneficial for outdoor enthusiasts who need to keep their devices powered on the go.

With a fast charging capability of 3A, it can charge an iPhone to 50% in just 30 minutes, and the three USB outputs (one USB C and two USB A) allow for simultaneous charging of multiple devices, which enhances its versatility and convenience. Regarding portability, the charger is designed to be compact and includes a built-in flashlight, making it suitable for outdoor activities such as camping and hiking. The ability to hang it on a backpack for continuous solar charging while on the move is a thoughtful feature.

However, the device is likely to be heavier than single-panel chargers due to the additional solar panels and larger battery, which might be a consideration for some users. Durability appears solid with built-in protections against short circuits and overcharging. The compatibility with various devices, thanks to its multiple USB ports, rounds out its practicality. The Hiluckey Solar Charger is a robust choice for those needing a reliable power source during extended outdoor activities, though its weight could be a drawback for users prioritizing ultra-light travel.

The BigBlue 28W Solar Charger is a strong contender for anyone seeking a portable solar phone charger, particularly for outdoor activities like camping or hiking. Its high solar panel efficiency of up to 25.4% ensures that you get optimal energy conversion even in less than perfect sunlight conditions. The charger features three USB-A ports with a combined maximum output of 5V/4.8A, allowing you to charge multiple devices simultaneously. However, it's important to note that if one device draws a significant current, it may affect the charging speed of the others.

Portability is a standout feature, with a compact and lightweight design (1.5 lbs) that makes it easy to carry in a backpack. Durability is enhanced by the use of Back Contact solar cells, which reduce heat buildup and extend the lifespan of the panels. The IPX4 waterproof rating offers basic protection against occasional rain or wet conditions, though the junction box is not waterproof, so some caution is needed. One drawback is that the charger cannot store electricity, meaning it needs direct sunlight to operate and cannot charge laptops or power stations.

It is compatible with a wide range of devices, including both Android and Apple phones, although it does not come with a lightning cable for Apple devices. The charging speed can be affected by environmental factors such as cloud cover and sunlight angle, so optimal conditions are necessary for peak performance. The BigBlue 28W Solar Charger is a reliable and efficient option for outdoor enthusiasts or anyone needing a portable energy solution while on the go.
