Nekteck 20W Solar Charger with 2-Port USB Charger Build with High efficiency Solar Panel Cell for iPhone 6s / 6 / Plus, SE, iPad, Galaxy S6/S7/ Edge/ Plus, Nexus 5X/6P, any USB devices, and more I wouldn't spend much time talking about the aesthetics, as it's well addressed in other reviews. It's sizable, and feels very well made. I like the mesh pocket design on the shade-side as things get quite hot under the direct sun and that design avoids your devices' lithium battery from exploding. I bought this charger to charge my power banks, and one of them has 8 3400mah panasonic 18650 batteries in it that's almost 28,000mah! I left the charger in my small side yard plug into the power bank, and it took it a couple of days to charge it up! I didn't follow closely on exactly how many hours of sunshine it has received (my estimate is 6h/day because building shades) or the totally Wh or Ah but it's pretty quick in my opinion. Just to make it more measurable, I hooked it up with a USB power meter (see pictures) under a moderately shiny day (not very shiny at all), and it's pumping 2.3A at almost 4V. It's already over its spec amps! I didn't connect the 2nd port to test its real full capacity which I will do later on. Besides, it's still a big mystery how it distributes the power supply to its two ports, and I will do a little research and share with folks here later on. Overall it's a decent product that gets things done. I like it.
