How to Choose the Best Solar Power Bank

As you may have noticed, solar power banks may be small but they can vary greatly.

In order to develop a list of the best solar power banks, we needed to consider quite a few different factors for choosing the best devices. 

Amount Of Times It Can Charge An Average Device

We decided that an average device is a smartphone because everyone has one. Those include iPhones or Samsung devices.

Older phones receive more charges out of the power banks. The more times it can charge an average device, the better.

Amount Of Time Needed To Fully Charge Using Solar Power

For many of the solar power banks on our list, the answer is a lot. That’s because the solar panels are quite small.

The batteries that they are charging generally have a large capacity. Charging them completely takes a significant amount of power.

According to the Elumis Foundation, different factors like humidity and cloudiness can affect charging times.

Solar power banks in optimal sun conditions will charge way faster than if you leave your solar power bank outside to charge on a cloudy day. 

That said, getting a few hours of charge on your solar power bank is good for a few charges of your cell phone or other small device.

Don’t be alarmed by the high numbers.

It is important to remember that for some of the solar power banks, the intended use for the solar charging feature is emergencies.

It is not intended to be a primary charging source. They are not designed to charge from zero. Rather, they are designed to be a maintenance of charge. That should take much less time.

Battery Capacity

This is a bit of a tricky one. It is generally measured in mAh.

That stands for milli Ampere (Ampere is unit of current and milli-Ampere is smaller unit of current) hour and is a unit of charge.

This unit of charge tells how much charge a battery is capable of giving.

The problem is that to put any meaning to this number, you need to know how much current that the device’s battery is drawing.

That can depend on many factors. It is impossible to say exactly how this will play out in a real-life setting.

In general terms, the higher the mAh, the more charges you can expect the battery to produce.

Size And Weight

Power banks are made to be portable. We checked the dimensions and weights of each of the solar power banks.

We did that to make sure the solar panels and batteries don’t make the devices too heavy or inconvenient.

Within the list there is some variation. In general, most are not much bigger or heavier than a smartphone. They’re easily portable and finding the right size for you is important.

If you’re looking for some foldable options, check some out in our guide.

Durability And Resistance To Weather

Solar panels need to be outside to work. Solar power banks are a little bit different from regular power banks.

Check out our recommendations on solar backpacks!

Solar power banks are a great tool for people who will be backpacking or trekking, so some solar power banks need to be extra weather-resistant.

Ecomena talks about this being the best device for outdoors enthusiasts. 

We looked at waterproof and dustproof ratings. As well as included covers and materials used to make the power banks.

This helped us determine their durability and resistance to weather.
