10 Best Ultralight Backpacking Solar Charger 2025 in the United States

The Anker SOLIX C300 is a powerful portable power station paired with a 60W solar panel, designed for outdoor activities like camping and emergencies. It delivers 300W of power with a 288Wh LiFePO4 battery, allowing it to charge multiple devices including laptops, phones, and small appliances. It offers a good range of ports—seven in total—including high-speed USB-C ports for fast charging and a car socket, making it quite versatile. The design is reasonably compact and about 30% smaller than similar models, but at 13.46 pounds, it is heavier than most ultralight backpacking gear, which could be a drawback if you prioritize minimal weight.

The 60W solar panel allows for sustainable recharging on the go, though it’s not compatible with some other Anker solar panels, so you’ll need to use the one included or similar compatible types. Charging speed is a plus here, with the ability to recharge up to 80% in about an hour using the dual USB-C ports, which is convenient for quick power top-ups. Durability is supported by impact resistance and smart temperature controls, adding reliability for outdoor use. While the battery capacity is good for many devices, careful power management might be necessary for longer trips without access to electricity. This power station is a solid choice if you need reliable, versatile power and don’t mind the extra weight, but it may not fit the needs of those focused strictly on ultralight backpacking.

The Power-Bank-Solar-Charger offers a substantial battery capacity of 42800mAh, which is great for long trips where power outlets are scarce. This large capacity means you can charge your devices multiple times before needing to recharge the power bank itself. It is designed with durability in mind, being waterproof, drop-proof, and dust-proof, making it suitable for rugged outdoor use.

The built-in super bright LED flashlight is a handy addition for camping or emergency situations. With two USB output ports, you can charge multiple devices simultaneously, and if your device supports it, you can benefit from the QC3.0 fast charging protocol for quicker power-ups. However, at 1.34 pounds, it may be considered heavy for ultralight backpacking, where every ounce matters.

Additionally, while it has a solar charging feature, the solar panel’s efficiency is low, and it should be relied upon only in emergencies rather than as a primary charging method. Regular charging through a wall outlet is recommended for faster results. If your priority is a high-capacity, rugged power bank with some solar capability, this could be a great option, but for ultralight backpacking, the weight might be a significant drawback.

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.
