Keeping your phone charged can be a challenge, especially when you are out and about. Plugging in your phone during a day at the office is a simple fix, but what about during a camping trip, day hike, beach excursion, or music festival? A solar-powered phone charger is a great way to be on the go and fully charged. These durable packs are weather-resistant, easily transportable, reliable, and eco-friendly. While they may not charge your phone as fast as a standard power plug, you will never be caught in a tough spot, no matter where you go.

The Addtop uses four panels to convert solar power into battery power for the most efficient charge. Unlike some products listed here, the Addtop charges a 25,000mAh lithium battery instead of connecting to your phone directly which means more options and increased speed when it comes to your charge. Not only can this heavy hitter juice up your devices, but it also comes with built-in, bright emergency LED lights that can shine in 3 modes: strobe, SOS, and normal. It measures 6.1 by 3.35 by 1.37 inches, weighs a bit over 1 pound, and can charge two devices simultaneously. The Addtop is water, shock, and dust-proof, which makes it a great choice for camping trips or other outdoor activities.
