Heading off-the-grid with your gadgets? Don’t forget to take a good power bank with you as well! Or even better a solar power bank! The latter 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. Read on to learn how to choose the best solar power bank for yourself!

It’s not a magical tool, however, and you shouldn’t expect your phone or camera being fully charged within a couple of hours or so. But it does really work. And since many of the top solar power banks are also shock and weather resistant, you can attach one to the outside of your backpack and forget about it.

For more serious endeavors, though, I would recommend you to think about a powerful portable solar charger + a high-capacity power bank (or a few of them).

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 smartphone, that you can use 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.

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 the FKANT Waterproof Solar Charger, one of our favorites among the best solar batteries.

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.

6. X-DRAGON Solar Power Bank Review

A compact 3-panel solar power bank for outdoors.

Charging a battery from the sun with solar panels of this size in general takes a lot of time. X-DRAGON says, that it takes around 25 hours of direct and strong sunlight to fully charge this 10 000 mAh power bank.

That means you should be looking at the solar charger feature more like an emergency solution. Especially if you are heading off the grid for more than a couple of days. But, yeah, that’s the same with all these small portable solar chargers.

9. RenGard Solar Powered Charger Review

A power bank built with backpackers and hikers in mind.

Rubber finish case makes this solar power bank rainproof, dustproof and shock resistant. But thanks to anti-slip corner protection you don’t need to worry whether your hands are dry or wet, when you are taking the battery pack.

2 gadgets could be charged simultaneously. Though, the capacity of the power bank isn’t that big, so keep that in mind. And if you are 2 travelers, better take 1 power bank each. Or if you have several devices, buy a power bank with a bigger capacity. The power bank itself, like all the top power banks can be charged also from the power socket and USB port.

10. Voltaic Systems Solar Charger

Ok – it’s not a solar power bank like the others. It’s a solar charger, which comes with a 4000 mAh power bank.

11. SunJack Solar Charger with Power Bank Review

And one more a bit more serious solution for bigger adventures – a set of a 20W portable solar charger + 2 x 8000 mAh power banks.

Thanks to 4 solar panels – all of whom are bigger than the ones on the solar power banks I’ve reviewed above – it charges much faster. In good conditions both batteries with total capacity of 16 000 mAh can be charged in about 10 hours. And 16 000 mAh is enough to charge 2 smartphones at least 2-3 times.

Even though it can look like a pretty big solar charger it all folds down to the size of an iPad, thus easily fits in a regular backpack. The SunJack Solar Charger is dustproof and shockproof, ready to be used outdoors.
