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 a 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.
