10 Best Ultralight Backpacking Solar Charger 2025 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 Goal Zero Nomad 50 is a solid choice for ultralight backpackers who need a reliable portable solar charger. Weighing about 6.8 pounds, it balances power and weight reasonably well, though it’s not the lightest option if you’re aiming for minimal pack weight. Its 50-watt monocrystalline panels offer good efficiency and can provide a steady charge for devices and power stations, making it useful for longer trips where you want to keep multiple gadgets running. The foldable design is practical, folding down to a manageable size that fits easily into a backpack, which helps with portability. It also includes both an 8mm charging cable and a USB port, so it works with a range of devices, including the popular Goal Zero Yeti power generators.

The materials and build feel sturdy enough for outdoor use, though it’s mostly plastic, so care is needed to avoid harsh impacts. Charging speed is decent for its size and power output, but keep in mind that actual performance depends on sunlight conditions. This panel doesn’t come with built-in battery storage, so you’ll need an external power bank or generator to save energy for later use. The product is backed by a one-year warranty and strong customer support from a US-based team, which is reassuring if you run into issues.

For those seeking a dependable, moderately lightweight solar charger with good compatibility and solid power output for backcountry adventures, the Goal Zero Nomad 50 meets these needs well. However, if your priority is the absolute lightest setup or integrated battery storage, there might be more suitable alternatives.

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.
