The best battery bank solar phone chargers

The good news is that there is now an easy solution – ‘solar phone chargers’. These chargers allow us to combine the free and abundant power of the sun with the magic of solar panels to ensure we’ll never be without a backup for charging our phones, no matter where we are.

Solar phone chargers (also referred to as ‘solar cell phone chargers’ and ‘solar-powered phone chargers’) are gaining popularity as they progressively become more efficient, durable, and less expensive. And there are virtually thousands of options available online.
The problem is that many of these new products are of questionable quality – and it can take a lot of work to find the one that properly fits your needs. But don’t worry, we did the hard work for you and scoured the internet for the best solar-powered phone chargers.
There are two main types of solar phone chargers:
- Direct solar cell phone chargers
- Battery bank solar phone chargers
We present to you our list of the best-rated direct and battery bank solar phone chargers.
An important thing to note about solar phone chargers: they are slow and are only meant to function as a source of backup power. If you compare their charging speeds and reliability with a standard power plug, you will be very disappointed!
These chargers connect solar panels directly to a phone through a USB cable. They are the simplest and most efficient form of solar phone chargers you can buy. Solar power is sent directly from the solar panels to the phone.
Advantages of direct solar cell phone chargers:
Disadvantages of direct solar cell phone chargers:
- They only work when there is sunlight
- Performance fluctuates, depending on the intensity of sunlight
- Slow to charge the phone
Here are the three best-rated direct solar cell phone chargers currently on the market:

1. BigBlue 3 28W solar phone charger
Easily one of the top-rated solar phone chargers, the BigBlue 3 is our number one pick for this category. A good solar phone charger is the one that strikes a balance between generating a sufficient amount of solar energy while also being easy to carry around.
With its four efficient SunPower solar panels that fold into a compact little bag, BigBlue 3 comes out on top. The BigBlue 3 charger shows up in almost every list of the best solar phone chargers you can buy.
If you are not expecting consistently sunny days on your trip, then don’t worry, as this charger will produce electricity even on relatively cloudy days. This is not the lightest or the cheapest direct solar cell phone charger you can buy, but if a few extra ounces and a few additional dollars don’t make a big difference to you, then the BigBlue 3 should be a no-brainer.
Specs: Four 7W SunPower solar panels with 21.5% – 23.5% efficiency, Three USB ports with a total of 5V/3.4a= 17W max current, Net weight – 20.6 oz.

These chargers have solar panels and a battery bank, turning them into a hybrid version of a battery bank and direct solar panel charger.
The whole point of a solar-powered phone charger is to work as a source of backup power in places where grid power is not available. A battery bank solar-powered phone charger allows us to access power even when the sun isn’t out.
Advantages of battery bank solar phone chargers:
- More reliable
- Can be used to charge devices daily
- Faster, better quality phone charging
- Greater compatibility with a wider range of phones and chargers
- Added feature of a flashlight
Disadvantages of battery bank solar phone chargers:
- Small solar panels generate very little power and cannot be used as a primary source to charge the battery
- Exposure to too much heat can shorten a battery’s lifespan
- Adding an extra device between the sun and your phone results in some loss of electricity along the way
Here are our recommendations for the top-rated battery bank solar-powered phone chargers.

Drum roll, please…our pick for the top battery bank solar phone charger is: Hiluckey!
