Product Information

If you’re setting and forgetting them while going out on day trips and leaving them connected to a battery, the best angle to set them at in most of the US is around 37 degrees. However, in the end, it didn’t perform quite as well as the Big Blue — even though it uses the same solar cells and design. They last up to 20 or more years in the field, and most, if not all, components of solar panels are recyclable.

Opt for a compact and lightweight option that fits easily in your bag or pocket, making it a breeze to carry around.Its charging pouch also had a hook-and-loop closure rather than a zippered closure like the other clones.

Unlike wall chargers or wireless chargersthat need to be plugged in, or power banks with limited battery capacity, a good portable power station can keep your devices powered up to 13 hours or more on a fully charged battery. I’ve written about countless outdoor companies, outdoor sports, and tested gear with publications including CompanyWeek, Outdoor USA Magazine (print), Elevation Outdoors, 5280, and more.

We liked the incredibly simple sundial on the corner of the device, which allows you to accurately aim the panel directly into the sunlight for maximum efficiency. If you’re going on a major trip with a group and are going to be away from civilization and access to other power sources for more than four or five days, like a backcountry bikepacking or climbing expedition, and want to do a lot of videography and documentation, you’re going to have different needs than someone on a solo trip. While the SolarSaga 100 is relatively lightweight and folds flat, it doesn't fold down as small as many other 100-watt panels we tested. While some thin-film solar cells have the advantage of flexibility and are often more lightweight, they’re less efficient. It’s the only solar charger we evaluated that can be linked to other solar panels and the only one that can be attached in a series to provide even greater charging power to a battery power bank.
