14W Portable Solar Panels 5V 2.1A USB

The 14W Portable Solar Panels is Wanderwell's foldable charger for off-grid power. Unfold it in direct sunlight and its two 5V USB ports charge phones, power banks and other small USB devices, with enough headroom to top up two phones at once. A smart chip reads each device and adjusts to the fastest charge it can deliver, and it works with both iOS and Android.

The panel folds in three like a wallet down to roughly paper size, so it drops into a daypack without taking over. Eyeholes and mounting loops let you strap it to the outside of a backpack and charge while you walk. The cells sit on industry-grade PET backed with heavy-duty polyester canvas, which makes the panel water-resistant against splashes and light rain. There is also a compact pocket with buckle straps to hold your phone or power bank against the panel while it charges.

Worth knowing before you buy: this is a sunlight-only charger with no built-in battery, so it makes power while the sun is on it and stops when the light drops. Real output depends on conditions and runs below the 14W rating in anything less than strong, direct sun. It charges over 5V USB only, which suits phones and small electronics but not laptops, and water-resistant does not mean you can submerge it.
