The Powerport 21W does it all. It is well made, light, and compact. It can also carry its weight as a charging powerhouse. It’s more efficient when charging one or more devices, and can recover its charge even after being shaded for a few minutes. The panel also works decently well on overcast days, whereas some of the lower wattage panels could not keep a charge going when clouds overhead. A larger watt panel means faster charge times, less interruption, and a more stable supply of power. After trying such a large range of panels, we realized that in this case, the larger the wattage makes a big difference after all. The Anker Powerport 21W is a great all-around panel for a reasonable price.
