ECOXGEAR SOLJAM AUDIO PLAYER

Big sound from this little device comes from dual 10-watt speakers and a passive subwoofer. That makes it a great holiday gift for the boater on your shopping list. It plays for up to 12 hours on a charge, and it will play longer with solar support. It’s waterproof and dustproof, with an IP67 rating. A waterproof charging port connects to a charger, or plug in your smartphone to recharge it. It floats if dropped, and there’s also a threaded hole on the bottom for versatile mounting options. $150; westmarine com
