Packing a massive 20W subwoofer (paired with a 10W driver), this Mokcao Bluetooth speaker can put out a lot more bass than you’d expect from a portable sound system. It can’t run for as long as most other speakers on its 7500mAh battery, only about five hours, but that should be enough for most house parties and backyard barbecues.

The speaker is currently on sale for $35 as part of a Lightning Deal, but if you miss out on that, you can still get it for $39 with promo code VCRELMFV.
