Charging devices on the go, whether commuting or venturing off into the backcountry for a day or two, is all the easier with the Voltaic Systems Array Rapid Solar Backpack. The 10W solar panel is 22 percent efficient, while the backpack itself consists of durable, weather-resistant, recycled PET fabric. It has a medium 25L capacity with many pockets and compartments for storing gear, from small devices to a large 15-inch laptop.

With its detachable 24,000mAh battery, you can get a full laptop, seven smartphone, or three tablet charges out of the backpack while traveling or exploring. Fully charging your computer takes up to six hours, while most smartphones are topped up with juice within an hour. It also features pass-through charging, enabling you to power your device and battery directly from the sun simultaneously. The battery also provides safe and regulated power, ensuring your devices charge up worry-free.

For a larger capacity solar backpack, the ECEEN 20W External Frame Hiking Backpack has an ample 68L of storage space. It’s made with a durable, water-resistant nylon and polyester blend and contains a multitude of compartments for storing gear, making it an ideal choice for multi-day or even more extended camping trips into the wilderness.

The external frame offers extra support and helps distribute weight evenly across the back and hips, while the trampoline suspension system assists with airflow between the back and pack.

In terms of charging, it has a 21W solar panel with a 24 percent conversion rate that you can use to charge a range of gadgets, from power banks to essential GPS devices. It’s removable, too, and has loops and carabiners that allow you to hang it from an RV, tent, or tree.

For something a bit smaller that will keep you hydrated while hiking or cycling, the ECEEN 7W Solar Hydration Backpack is a top pick. This 14L rucksack is big enough for day trippers and includes an integrated 2L water bladder. The bladder is easy to fill with fresh, nourishing H2O thanks to the large mouth, and coupled with the 22 percent efficient solar panel, you can stay hydrated and connected wherever your feet take you.

The solar panel is removable; you can hang it from your tent when you end your day’s hiking, fishing, cycling, or whatever gets you moving. It charges directly from the sun and doesn’t include a built-in battery pack. But you can use the solar panel to power an external power bank, ensuring you have juice for later.

If you need something larger, there is a range of sizes that come with different styles of compartments and pockets to suit your needs. Some designs even come with a battery pack for extra convenience.

Despite struggling to roll off the tongue, the SGUESIKR 12W Solar Backpack is another quality solar charging bag for outdoor activities. It also has other uses, such as a school backpack that ensures students keep devices charged throughout the day or a bag to take on business trips that prevents your smartphone or other devices from dying at a critical time.

This backpack features a 12W, 5V semi-flexible solar panel with a conversion efficiency of 19.8 percent. It’s ideal for keeping smartphones, tablets, earbuds, and other small devices juiced up while on the go. It’s lightweight and comfortable, with ergonomic 3D padding on the back and shoulders, and also offers comfort and good weight distribution throughout the day when carried for extended periods.

With a 20L capacity, you can fit a fair amount into the rucksack. Additionally, it has a compartment for a 17-inch laptop or 10.1-inch tablet and other pockets for smaller devices. Finally, the IP67 rating ensures it can survive heavy downpours, while dust and other debris can’t penetrate it.

The Kingsons Beam Solar Backpack is a stylish travel bag for practical on-the-go powering. You can draw directly from the sun with the 8.5W Miasolé flexible solar panel and keep small devices topped up with juice throughout the day using the integrated charging cable and USB port.

The design of the bag is ergonomic and lightweight. It features soft padding on the shoulders and a 3D suspension back, providing good airflow and ultimate comfort. Additionally, there’s room for a 15.6-inch laptop and a 10.1-inch tablet, while the 19L storage space is ample for a change of clothes, files, paperwork, schoolbooks, or whatever else you need to fit in. With two side pockets, you can also squeeze in a water bottle or a coffee flask for your daily commute.

There’s also a hidden pocket on the back to keep valuable items such as a wallet or passport. Furthermore, the durable polyester fabric is water-resistant and helps prevent your items from getting wet in an accident or downpour.

Another practical solar rucksack from Voltaic Systems is the OffGrid Backpack Solar Charger. It’s similar in size to the Array backpack but comes with a more affordable price tag and a smaller battery. You can juice your gadgets up from this 12,800mAh battery or charge directly from the sun via the type-A and type-C USB ports.

The 10W panel charges smaller devices in around three to four hours while powering the battery throughout the day enables you to charge your smartphone up to four times or your tablet twice back at the RV or campsite later at night. You can also conveniently and quickly charge the battery from a wall outlet.

At 25L, it has ample enough storage for multi-day use if you are a light packer. It also has enough for an overnight camping trip into the wild. Packing your devices is easy with a dedicated 15-inch compartment for laptops and tablets, while there’s also plenty of room for cables, adapters, and photography equipment. Essentials like water bottles, sunglasses, and sunscreen all have a home, too.

The XTPower Backpack from Jaunch is another large option for a solar charging bag at 46L. While it may be too big for everyday use, it’s ideal for multi-day camping trips into the backcountry.

It features a high 22 percent efficiency 6W solar panel which you can use for charging inside or outside the bag. You can also hang it from a tree or tent for all-day charging to ensure you have power for your devices at night. Smartphones and other small gadgets are fully charged within a few hours, making it an ideal choice for backpacking, fishing, and camping trips.

Organizing your travel accessories, gadgets, and clothing is a cinch, as the bag has plenty of pockets and lots of room. The dedicated laptop compartment is padded and holds laptops of any size. Additionally, with its adjustable shoulder straps and hip belt, you can distribute the weight to areas where you feel most comfortable, while the bag itself is lightweight.
