What Matters Most in Outdoor Activities?
At just 17.2 lbs, the 440W SolarBag delivers serious power without the bulk. Compact enough to slide into your trunk or under a bench seat, it's made for travelers who pack light but don't want to compromise on energy.
Forget the need for perfect flat ground or heavy mounts. Just unfold it like a picnic mat—on a slope, against your windshield, or anywhere the sun shines. Setup takes seconds, so you can focus more on relaxing.
The unique zip design gives you full 440W in one piece for fast charging, or two separate 220W panels for greater flexibility. Charge your power station at camp while taking one panel to charge your camera or phone on the move. Each half weighs under 4kg, so mobility is never a burden.
Reinforced with fiberglass for better durability—even if stepped on while laid flat. Rated IP65 waterproof: a quick wipe after rain or dew is all it takes. Backed by a 3-year warranty for total peace of mind.
Equipped with high-efficiency N-Type cells and ETFE coating, the SolarBag delivers up to 440W output in full sun—nearly its full 440W rated capacity. That means real energy for real needs, not just on paper.
With both MC4 and 6 USB output ports, you can charge most major brands of power stations plus phones, drones, cameras, and more—all at the same time. Besides, you can pair it with the S1 controller to charge lithium batteries directly.
