As part of the Gold Box Deals of the Day, Amazon offers the Eton Rugged IPX4 water resistant Rukus solar-powered Bluetooth USB charging speaker for $39.99 Prime shipped. That’s $37 off the original list price/ Newegg’s listing and the lowest we’ve ever seen for this highly rated summer speaker/USB battery combo.
This speaker features a solar panel with an internal Li-ion battery and it can charge your devices while still listening to your music. You can get 8+ hours of play time from the battery even without sun and it’s IPX4 water resistant for use outdoors or even pool side. Rated 4.2/5 stars from over 1,000 Amazon customers.
Take your music with you everywhere, the sunshine will power the rukus to keep your tunes playing. If your phone starts to die, no worries, plug it into the rukus to get a charge. When it gets dark, the internal lithium battery will keep the music going for hours or you can use the included USB cable for non-stop songs. Stream all your music from almost any Bluetooth-enabled smartphone, tablet or computer. And for non-Bluetooth devices, there’s an aux-in. It’s time to start a Rukus!
