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 Anker SOLIX PS100 Solar Panel is a strong contender in the ultralight backpacking solar charger category, though it leans slightly heavier at 12.07 pounds compared to some other options. However, its weight is balanced by several advantageous features. The panel boasts a high energy conversion efficiency of up to 23%, which ensures a faster charging time compared to less efficient models. This is particularly useful for backpackers who need to maximize sunlight exposure during limited daylight hours.

Additionally, the adjustable kickstand with four different angles (30°, 40°, 50°, and 80°) allows for optimal sunlight absorption regardless of the time of day or season, enhancing its practical usage in various outdoor settings. The IP67 waterproof rating adds a layer of durability, protecting the device from rain and making it suitable for rugged adventures. Another noteworthy feature is the stable MC4 connection, which maintains high conductivity with minimal energy loss, a crucial factor for consistent performance. The panel is also foldable, which aids in portability, though its weight might still be a consideration for ultralight backpackers.

The robustness of the ETFE coating provides assurance that it can withstand rough handling and environmental challenges. Compatibility-wise, the inclusion of multiple cables (MC4, XT-60) enhances its versatility with different devices. One downside could be the lack of built-in battery storage, meaning users would need separate storage solutions. Those who prioritize efficiency, durability, and versatile charging options might find this product especially beneficial, despite the trade-off in weight.

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.
