10 Best Ultralight Backpacking Solar Charger 2026 in the United States

The BLAVOR Solar Charger Power Bank is a solid choice for ultralight backpacking with its compact and lightweight design, weighing only 9.2 ounces. It offers a decent power output with a 10,000mAh battery capacity, which can effectively charge devices multiple times. The fast charging USB-C output and wireless charging capabilities are standout features, allowing you to charge up to three devices simultaneously. This is particularly useful when you have multiple gadgets on your trip.

The charger is also designed with durability in mind, being IPX5 waterproof, dustproof, and shockproof, ensuring it can withstand harsh outdoor conditions. Additionally, it includes practical features like dual bright flashlights and a compass carabiner, which are great for outdoor safety and convenience.

However, one potential drawback is that solar charging can be slow and should be considered as a backup rather than a primary charging method. Also, while the solar panel is a useful feature, the small size might limit its efficiency in fully charging the power bank quickly. Despite this, the BLAVOR Solar Charger Power Bank remains a robust and versatile option for backpackers looking for an ultralight, multi-functional charger.

The BigBlue 30W Solar Panel Charger is a solid choice for ultralight backpackers who need a reliable, portable power source. Weighing just under 1.85 pounds and folding down to a compact size, it’s easy to carry without adding much bulk to your pack. It offers a decent 30 watts of power with both USB-A and USB-C ports, including an 18W fast-charging USB-C port that works well with popular devices like iPhones, iPads, Samsung, and LG phones. The charger also has a DC output for small power stations, increasing its versatility.

Durability is a strong point here, thanks to advanced lamination technology and an IP68 waterproof rating (though the junction box isn’t fully waterproof), meaning it can handle occasional rain and rough outdoor conditions. The solar panels use high-efficiency monocrystalline cells with up to 24.7% conversion efficiency, giving you quick charging times when sunlight is good. This charger is designed for direct device charging, so you’ll need a power bank or battery to save power for later use.

The output can vary based on weather and how well you angle the panels, but the BigBlue panel reliably charges multiple devices during hiking, camping, or outages. Included accessories like carabiners and a USB-C cable make it convenient for attaching and connecting on the go. This model is well-suited for those who want a lightweight, durable solar charger primarily for direct charging and carry a separate battery; built-in battery storage is not included.

The SOARAISE Solar Charger Power Bank is a powerful option for outdoor enthusiasts who need reliable device charging on the go. It stands out with its massive 48000mAh battery capacity, which means it can charge multiple devices multiple times—great for extended trips without access to electrical outlets. The charger features 4 solar panels that improve solar charging speed significantly compared to typical single-panel chargers, though solar charging will still be slower than plugging into the wall.

With built-in cables for USB-C, iOS, USB-A, and Micro USB, plus a wireless charging pad, it supports a wide range of devices and up to seven devices at once, making it very versatile. The 3A fast charging USB-C port is beneficial for quickly topping up your phone, which is convenient during short breaks outdoors. Durability is another strong point, as the unit is waterproof, shockproof, and dustproof, built to endure rough conditions on trails or campsites.

The size and weight (1.5 pounds) might be a bit heavy for those strictly seeking an ultralight backpacking charger where every ounce counts. While the solar panels are efficient, relying solely on solar power for quick charging may not be practical in low light or cloudy weather. For users who prioritize portability above all else, this may feel bulky, but for those valuing capacity, device compatibility, and durability, it delivers impressive performance and convenience during outdoor adventures.
