There are tons of power bank options available out there, but some among them manage to distinguish themselves with the help of unique features. These include solar power banks which can actually charge themselves using the power of the sun. They are especially suitable for those who go camping a lot, as they don’t always have power outlets to recharge their regular power banks. This list takes a look at the best solar power banks you can buy in India in 2018 at the best price.
This one is expensive compared to others, but it has one feature that is sure to impress you. GRDE’s 10000mAh power bank comes with an IP67 rating, making it water and dust resistant. Moreover, its strong body also gives it resistance against drops, making it a great companion for those who go hiking and camping a lot. It comes equipped with carabiner for hanging it from your backpack, and also a compass for easy navigation. Another attribute worth highlighting is its dual flashlight combo which ensures that there’s enough light at hand when you need it.
This is meant for someone looking for a very cheap solar power bank. Coolnut has given it a shell made from fiber and metal, but it doesn’t measure up against the other players on this list when it comes to durability. It has two output ports and comes with three USB cables (2 long and 1 short). It does feature a flashlight, but it’s quite weak in terms of its brightness. In case you’re wondering, this one’s not waterproof.
The Poweradd Apollo 2 has one feature that’s rarely seen on power banks – a cigarette lighter. It’s tucked away on its side surface, allowing those who smoke regularly to forget about carrying a separate lighter wherever they go. The Apollo 2 is also waterproof and shock resistant which gives it some added appeal. Its dual USB ports are well hidden, while its dual flashlights come with three different modes of brightness. A hinge also exists on one of its corners to help you strap it on your backpacks.
This product from Cobra Electronics benefits from a book-like design which allows you to unfold its body in order to expose the solar cells. The 6000mAh CPP 300 SP isn’t as bulky as its competitors, which is a good advantage to have, especially for a product that you’ll mostly be using outdoors. It comes equipped with two full-size USB ports at the top for charging your devices. Moreover, both its side surfaces hide small cables, one among which has a microUSBport for charging the power bank itself, and the other, a full-size USB port for charging another device.
If you’re looking for exquisite design, this power bank from RAV Power will surely end up appealing to you. It’s a beautiful piece of hardware with a whopping 15000mAh capacity cell inside it. One of its two output ports delivers fast charging thanks to its 2.1A output, whereas the other one is a regular 1A port. There’s even a microUSB input for charging it through the regular method. Its solar cells are placed right on its front surface, and it even comes with a handle for easily strapping it to your bags or belts. Its rubber linings ensure that there’s some ruggedness involved in the whole affair. Moreover it also happens to be waterproof up to a certain extent.
The most important thing to remember while buying solar power banks is that they take an extremely long time to get charged through sunlight. Sometimes days and even a week for those with really high capacity cells.
Always check the output frequency of a power bank. If it is low (e.g. 5V/1A), then your devices will charge slower than when the output is higher (e.g. 5V/2.1A). Power banks with more than one output port often have one slow port on them.
And it’s common knowledge that the actual battery capacity of a power bank is almost always lower than what is shown. This is due to a phenomenon called conversion rate. To put it simply, some amount of battery is eaten up inside the power bank during the conversion of its voltage.
