It’s All About the Sunlight
Before we actually tell you about the characteristics and feature of this Anker product, let us first address the issue we believe is important: who are the possible buyers and users of the Anker 21w solar charger? Well, the market for these cool chargers is, we kind of hate to say it, quite narrow.
Before you stroll down to your nearest mall and get yourself one of these, think about how much time you are going to be spending in the wilderness, that is to say, off the grid, and how much time you are going to be exposed to direct, summer sun?
If the answers to both questions are „little“ or „maybe sometimes“ then your best bet is to skip the purchase of a device like this and stick to the good old-fashioned extra battery to store additional energy for charging up your smartphone or another device.
Lack of Storage
But, if you are an avid trekker and you love hiking or mountain biking across Arizona or Utah in July, while listening to music on your iPad, then this is the perfect device for you. As you might have concluded by now, this device does not come with an integrated or additional battery. This means that the only time you can use it to charge your phone is when you are exposed to sunlight, preferably the strongest possible.
This makes it not so handy for people who need to recharge their phone frequently, but do not live in the sunniest of environments and where winter is a reality. Regardless of all this, the Anker 21W is a high-quality solar charger with overall good qualities we will explain below.
The device uses three solar panels to generate enough electric current to power your mobile devices.
According to manufacturers data, the charger will provide enough juice to power two mobile phones (iPads and others) at the same time, but this is more a wish than reality, since the maximum output of the designated 2.4 amps per each USB port or 3.0 amps for a single port is achievable only if you are standing right under the July sunlight at noon.
Otherwise, it will take a bit more time to charge up. Sizewise, the Anker is very handy, measuring about 6“ X 11“ folded, so it will be easy to carry it around with you. Also, the sturdy canvas will give solid protection from the elements, but be careful not to expose it to direct rain. Positioning of the device towards the sun is a treat, thanks to the adaptability of the design.
Should I get one?
As we said above, if you happen to live in a generally sunny place, and you love to spend your long weekend away from standard sources of electricity, then run off to the store and get yourself an Anker 21W. If not, our suggestion is to rely on the power stored in a portable battery.
