A solar power bank will come in extremely handy if you are heading out on a longer adventure. In case of necessity unlike with a regular power bank you will be able to recharge this one also from the sunlight. It’s not a magical tool, though. You shouldn’t expect your phone or camera being fully charged within a couple of hours or so.

But it does really work.

Many of the top solar power banks are shock and weather resistant. Meaning you can attach one to the outside of your backpack and forget about it. Cool, isn’t it?

What Is a Solar Power Bank?

Let’s answer this question first – what is a power bank?

Power bank is a portable battery, usually not much bigger than a phone. You can use it to charge your electronics. It’s important to add, that mostly they are made to be used with smartphones, tablets, e-book readers, cameras, but you can’t power more power-hungry appliances like TV. At the same time now you can already find a power bank strong enough to charge your laptop as well.

Solar power bank, as its name suggests, is a portable battery, that can be charged from the sunlight.

Yes, as simply as that – put it in the sun and it will charge.

Charging from the sun can take quite a lot of time.

You may even need a full day of sunshine to fully charge your phone and a couple of days to fully charge your tablet. But, anyway, you can always be sure, that you will have this option. Many of the best solar power banks can be charged also from power socket or USB.

So it’s always a good idea to charge your power bank at home before heading off-the-grid.

Many of the top solar power banks are also shock and weather resistant.

How to Choose the Best Solar Power Bank for Yourself

To find the best solar power bank for your needs, answer these 2 questions first:

1. Where Are You Planning to Use It?

Or more exact – what conditions you want it to be ready for?

Do you want a solar power bank just as a backup, while you are wandering around the city or sunbathing on the beach. Or you need a power bank, that can be used in harsh environments as well? Maybe you need a 100% waterproof power bank?

If the latter is true – check out waterproof solar chargers.

2. For How Long Time Are You Going Off-the-Grid?

This will help you to understand, how much does power bank’s capacity matter to you.

See, if you are going away for more than a day or two, or if you just have more than a couple of gadgets, that you are planning to use it for, then I will recommend you to look for at least a 15 000 mAh power bank. Or – if the sun clearly will not be an issue, than look for a solar power bank with bigger solar panel (faster charging one).

15 000 mAh nowadays is enough to charge 1 powerful smartphone 4-5 times (a tablet – 1-2 times).

With the best solar phone charger you’ll be able to charge your phone once a day for a week, or even more.
