A high-tech set of portable solar panels with two USB ports to allow for the charging of several devices simultaneously. Though this set of panels does not include any power storage options, it's a good choice for low-to-medium users on trips that might last a few days.
Pro Identifies most effective voltage for devices
The Anker is equipped with technology to identify the most effective charging conditions for devices plugged in, to offer the quickest charge without wasted energy. Keep in mind that this requires a relatively strong level of direct sunlight to utilize.
Pro As portable as a tablet
When folded, this set of panels is about one foot by six inches, slightly larger than an iPad. With a basic bag or a backpack, the panels won't be a massive drain on available space. This particular set of panels weighs in at 14 oz (less than a pound), so it won't be a major impact on most hikes or backpacking trips.
