Solar power bank reviews

There are so numerous electronic devices available today and almost all of them use batteries. Anything from Smartphones, Go Pro cameras up to electric cigarettes use batteries, meaning when they run out, you can’t use your device anymore until you recharge it. Of course, you can always carry a charger with you, but then again you’re limited in some way as you need a power outlet. Fortunately, there is another solution – portable backup battery or a power bank. These relatively small portable batteries are available in many different capacities meaning you can get a full charge or even two full charges out of decent power bank.

But what if you can’t recharge your power bank? Maybe you’re off on a hiking trip or just want to live off the grid. There is a solution – a solar power bank. Not only you get a portable battery, but also a small solar panel that’s connected to your battery and when it’s exposed to the sun, it will recharge. In the result, you get 100% free energy source. All you need is some sunlight and that’s it.

A solar power bank is an ideal choice for those who love going on adventures. Camping, fishing, rafting, hiking – you name it. Just attach it to your backpack while your hiking and at the end of the day, you will be able to recharge your electronic device.

How to chose the best solar power bank?

If you have decided to get a solar power bank, then before making a purchase, there are few things to consider and keep in mind. Getting a solar power bank that doesn’t fit your needs is a waste, therefore spend some time figuring out what do you exactly need.Solar power

Capacity
Probably the most important factor is power bank’s capacity. To choose the right one, you must know what devices you’re planning to charge. Despite your device, we always advise getting at least 2000mAh battery as it can do one full smartphone charge. And again, of course, it depends on your device. So if possible, always go for the highest capacity solar power bank, but remember that higher capacity means larger batter and also more weight that can play a huge role while hiking for many days.

Brand
It’s no lie that more recognizable manufacturers usually make better products, but they are also noticeably more expensive. You definitely want to go for the best and highest quality product. The thing is that solar cells aren’t the most effective way how to harness energy. A regular solar panel transforms only about 22% of solar energy into electrical energy. However, a high-quality panel can transform twice as much (around 40%). In the result, one solar power bank can be twice effective as another one.

Rugged build
If you do plan to use your solar power bank for hiking and other outdoor activities, you probably want to get it as rugged as possible so no rain, water splashes, snow or mud could harm it. Fortunately, there are such devices.

Features
While the main purpose of solar power bank undoubtedly is recharging your electronic devices, you can also have some other features like a flashlight, multiple USB ports and attached carabiners which are extremely useful while being outdoors.

Final words

Although solar power bank is ideal for camping and hiking, you shouldn’t think that it’s made to be a primary recharge source. Of course, you can charge your phone or any other electronic device with it. However, usually, solar power banks recharge very slowly. They can work great just to keep your smartphone alive so you could make few calls and send some text messages, but don’t think that you will be able to surf on the web, play games, and photograph. It simply won’t be able to recharge your smartphone at that rate.

Before going anywhere, you should always fully charge your solar power bank with regular DC power cable. Note that solar power banks also differ, some are more effective and some are less effective.
