The solar power bank is one of the newest addition to the portable charger industry. You will not find many of them available for use. That’s why there are very few people who get to know about this gadget.
A solar power bank uses solar power from the panels to charge itself but a solar charger receives energy from a solar panel and delivers the power straightaway to the devices. Today, we are not reviewing a solar power bank. We will give the Anker 21W solar charger review, which is among the most popular solar chargers on the market available right now.
Let’s see if the Anker 21W solar charger is good enough for charging devices instead of using a solar power bank.
Benefits of Anker 21W Solar Charger
Decent Charging Speed
The Anker 21W solar charger has an impressive charging speed. We charged a 6000mAh portable battery for the test. Surprisingly, the 21W solar charger from Anker charged it fully within around 3.5 hours. When we charged the same battery plugging into the wall socket, it took almost 30 minutes more for a full charge. Therefore, we can easily say that the 21W solar charger is quick and efficient at charging.

Multiple Device Charging
You can charge two devices simultaneously using this charger. Though the solar charger is small, it can charge impressively on both devices. However, the charging speed will obviously drop by almost half.
Durability
The Anker solar charger is made well with PET polymer-faced solar cells, which give it industrial-grade strength. And, this is the reason it is more durable and can easily withstand harsh conditions outdoors. The durable polyester canvas has made it a reliable product for users.

Anker has a positive reputation among consumers because of its excellent customer service. The company provides a three-day return policy with a full refund in case you find any issue within three days. Besides, they offer an 18-month warranty service for the solar charger.
Design and Portability
The Anker 21W charger is not made with a single panel. It is made especially with a tri-fold panel model. These three panels ensure to get a large surface area for solar input. In contrast, its tri-fold design gives a compact and smooth look. You can carry it just like a magazine or thin book. So, this Anker gadget is very lightweight and easy to handle. Yet, there is no decrease in its capability and quality.
