Lightweight and portable thanks to its folding storage case. Charges smartphones and small electronic devices well, users report.
At 21W, it is the most powerful of all the panels, so it makes sense that it delivers a consistent charge to two devices at once. In ten minutes, the 21W from Anker was able to charge a single battery to 3%. Once another battery was plugged in, the panel continued charging the two batteries and even increased the first from 3% to 4%. No other competitor was able to increase the charge of the batteries during the short period.
Incorporates the fast charging technology that allows it to deliver up to 2.4 amps per USB port under direct sunlight. Moreover, the simple design of the product makes it the ideal backpack solar charger. The compact size of 11.1 x 6.3 inches and the ultra-thin design of 1.1 inches when folded, offers portability and simplicity, making it suitable for the camper or the adventurous one. Lightweight is also an important property, representing only an additional 14.7oz of weight to your backpack.
The eye-hole rings are made of stainless steel and the rest of the solar charger is made of rugged polyester. The USB Port Hub is covered by the Polyester as well. When you fold the charger it does a great job at keeping the charging ports very safe and although this solar charger isn’t exactly water resistant, it does a good job at keeping water away from the main parts.
Made up of three polymer-faced solar panels sewn into a polyester canvas material with a fourth section designed as a Velcro pocket, the entire device folds up to be about an inch thick. This makes it perfect for stashing in just about any bag that has a laptop/tablet compartment. It also turns out to fit perfectly in a small F-Stop Gear ICU right on top of everything in it. This worked out great for me since I often use this in my hiking pack.
Four metal-reinforced holes in each charger’s corners let you attach carabiner hooks to mount the opened panel, most likely on the outside of a large camping/hiking backpack; Anker lets you supply them yourself if you need them, packing in a micro-USB cable.
The Anker is equipped with technology to identify the most effective charging conditions for devices plugged in, to offer the quickest charge without wasted energy. 1W panel set can accommodate larger or more power-hungry handheld devices, able to charge a tablet and a phone simultaneously.
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.
Hook this solar charger up to your backpack on your next hike and charge your phone or battery pack as you walk. The panels unfold to span about 18 inches, which is lots of surface area to capture sunshine. It can charge two devices at once and is super lightweight, weighing in at just under a pound.
Our top pick for the best solar charger since it offers an amazing combination of price, portability, and charging speed. Its performance leaves most of the comparable competition behind and it delivers where it counts: reliable power output.
Anker's solar phone charger makes it to our top three, thanks to some great reviews. Anker uses three 15W highly efficient (21.5% - 23.5%) SunPower solar panels. Weighing just 14.7oz, this solar charger is the most lightweight and compact variation in this category. So, if you want to use some of that free solar power during a camping trip without making your backpack heavier, this is your best bet.
One of my favorite technological lifesavers. The power port is like a power bank, only this time it’s powered up by the sun, not from the electricity flowing from your wall outlet. This makes it a very versatile product. Not only does it produce power for your device when you’re on the go, it also helps you get introduced to solar panels and energy. Think green power. In addition, solar-powered portable phone charger allows you to charge two devices simultaneously because we all have more than 1 USB device.
