When I think of Eton, I normally think of solar-powered emergency preparedness radios, flashlights, and chargers. The ruckus XL isn’t for emergencies, unless you’re talking musical emergencies. The rukus XL is packed with speaker drivers – two tweeters, two woofers, and four passive radiators – and delivers 22W of sound. It connects to your smartphone or tablet via Bluetooth, so there are no wires to get tangled, although you can use the USB port on the rukus XL to charge your device in a pinch. The rukus XL has a large 72-in² super-efficient, monocrystalline solar panel that can fully recharge the built-in lithium battery in about 5 hours, or you can charge it with the included AC charger in about 2.5 hours. It’s great for using at home or for taking with you. It’s available now for $199.99; check the product page for retailers.
