Off-grid string lights that don't need to be taken down to recharge—we needed these, and MPOWERD delivered. This set's got 20 shatterproof bulbs on a 44 foot nylon-braided cord, with multiple modes and up to 40 hours of runtime on a single charge. And it's expandable—daisy-chain a few together for larger campsites, no hassle at all. The base detaches, too, so you can charge it under the sun or via USB and get right back to lighting your site (or your bedroom).
