Amazon is right now offering the Anker 21W 2-Port USB Portable Solar Charger with Foldable Panel for $52.49. Normally selling for $70, today’s offer allows you to save directly 25 percent on the original price.
While you’re out enjoying the great outdoors, take advantage of another benefit. To begin charging your devices, simply spread out the solar panels or attach them to your pack.
PowerIQ, which is exclusive to Anker, detects and mimics your device’s original charging protocol to deliver the quickest possible charging speed of up to 2.4 amps per port or 3 amps total (with enough direct sunlight). Weather-resistant outdoor durability is provided by industrial-strength PET polymer-faced solar panels sewed onto a durable polyester canvas.
The compact dimensions (11.1 6.3in folded or 26.4 11.1in opened) and stainless-steel eye-holes on each corner make it easy to attach to backpacks, trees, or tents. Its lightweight, ultra-thin construction makes it excellent for lengthy hikes.
Except for the iPod nano, iPod Classic, HP TouchPad, and Asus tablets, it is compatible with Apple and Android smartphones, tablets (including the Nexus 7), and other USB-charged devices.
