- Solar chargers are useful for faraway excursions in which you won’t have access to electricity. Campers, hikers, and other outdoor fans can benefit from a solar charger.
- Many modern solar chargers are extremely lightweight and portable. It’s easy to pack a solar charger and take it with you wherever you go.
- Solar power is a completely renewable energy source. If you’re looking for an eco-friendly way to power your electronics, this is it.
- If you like to spend a lot of time outdoors, you can charge your devices for free while doing something you enjoy.
Some solar chargers have loops, grommets, or straps that attach to a backpack so you can charge your devices while walking.
Types of solar chargers
You can find three main types of solar chargers on the market: monocrystalline, polycrystalline, and CIGS (which stands for copper, indium, gallium and selenide) solar chargers.
Monocrystalline solar chargers
- Monocrystalline solar chargers are rugged and durable. They tend to last longer than CIGS models.
- As long as it’s sunny out, monocrystalline solar chargers are the most effective variety.
- Newer foldable monocrystalline solar chargers are fairly light and portable.
- Monocrystalline solar chargers aren’t as lightweight or compact as CIGS chargers.
- In partially shaded conditions, monocrystalline solar chargers aren’t very effective.
Price: Basic low-power monocrystalline solar chargers start at less than 20. Powerful high-end models tend to cost 175 to 200.
Polycrystalline solar chargers
- Polycrystalline solar chargers tend to be the most inexpensive option.
- Most polycrystalline solar chargers are very durable and long-lasting.
- Polycrystalline solar chargers are similar to monocrystalline models, albeit slightly less efficient.
Price: We found basic micro polycrystalline solar panels for as little as 5 to 7, but they’re not extremely powerful. You can get a stronger 40-watt model for around 50, though some powerful high-end options cost over 100.
Cigs solar chargers
- CIGS solar chargers are the most lightweight option available.
- Since CIGS solar chargers are made from flexible fabric, they can be rolled up like a poster and put in a bag when not in use, making them very portable.
- CIGS solar chargers are significantly more effective than monocrystalline and polycrystalline models in overcast and partially shady conditions.
- Due to their thinness, CIGS solar chargers aren’t as durable or long-lasting as either crystalline type.
- CIGS aren’t as efficient as monocrystalline or polycrystalline solar chargers in sunny conditions.
Price: CIGS solar chargers can cost anywhere from 50 to 300, depending on their power and quality.
A good solar charger should have auto-restart technology.” If it stops charging because the sun disappears behind a Cloud, it will automatically start charging again once the sun returns.
Considerations for selecting a solar charger
The wattage of a solar charger dictates how powerful it is and how quickly it will charge your devices. Basic solar chargers may pack less than five watts of power, whereas the most powerful units can yield 100 watts.
While a four- or five-watt charger can tackle your average smartphone, it will take three to four hours to get it to a full charge. Ideally, you should opt for at least a seven-watt charger for a single phone to speed up the charging time. If you plan to charge multiple smartphones at the same time, or if you’re charging a power-hungry device like a tablet, consider a 15-watt charger. For a laptop, DSLR camera, or video-recording equipment, we recommend a solar charger with a minimum of a 30 watts.
The output power of a solar charger is measured in amps. Find out the best amperage for the devices you want to charge, and choose accordingly. If your charger has more than one port, the manufacturer may list the output power for all the ports combined or for each port individually. Be sure to double-check this spec to make sure you know what the manufacturer is referring to.
How important is the weight of your solar charger to you? If you’ll only be using it on camping trips where you can drive right up to your pitching site, weight may not be of huge importance. But if you’ll be taking it on multi-day hiking trips where you really want to keep the weight of your pack down, a lightweight solar charger would be the best option.
Most manufacturers give a rough idea of how long a solar charger needs to power an average device. Of course, the charge time will vary depending on a number of factors, including the battery size, the power requirements of the device you’re charging, and how sunny it is.
If you’ll be using your solar charger in an area that’s not overly sunny, opt for the most powerful model you can afford. The extra power will help you take advantage of any fleeting minutes of sunshine.
Estimated charge times are usually based on perfect full-sun conditions, so adjust your expectations if you’ll be using it somewhere further up north.
Q. Is a solar charger capable of charging multiple devices at once? A. Many solar chargers come with multiple USB ports so you can charge several devices at the same time. This is ideal if you’re going on a family trip and want just one charger for the whole party. However, be sure to consider the wattage of your chosen charger; a low-power charger will take a long time to charge more than one device.
Q. Can I recharge a device that uses a 12V cigarette port with a solar charger? A. While you can get adaptors to charge a range of different devices that don’t use a USB port, most solar chargers aren’t capable of tackling items that charge from a 12V cigarette port.
Q. Does the listed weight of a solar charger include all cables, batteries, and other accessories? A. The listed weight of a solar charger can sometimes be misleading. While you’d expect the listed weight to include all essential accessories, some manufacturers only list the weight of the panel itself. If weight is important to you, be sure to check what the listed weight includes.

Reasons your solar power bank is not charging
There are many reasons why your solar power bank might not be charging. Here are the five most common ones:
The battery has reached the end of its life
Unfortunately, no battery lasts forever. It’s inevitable that it’ll reach the end of its lifespan after performing a certain number of cycles. If you’ve had your solar power bank for some time, your battery might have lost its ability to hold a charge.
You’re not using it properly
Although technically, you use your solar power bank while it’s charging (in an emergency, for instance), this practice isn’t recommended. Doing so frequently may result in your solar power bank not charging or charging erratically. When you do this, the power banks’ battery is in line (or in series) with the gadget. The result is a higher power draw which leads to excessive heating that can damage your battery.
Your solar panel isn’t getting enough sunlight
A common misconception is that the solar panel in your solar power bank can generate electricity on a hot day, even when placed in the shade. That is not true — solar panels require direct sunlight to work effectively. Additionally, solar power banks require a minimum amount of luminous flux per area unit (also called lux). If they don’t receive the minimum amount of lux, they won’t start charging via solar. The following image showing the charging instructions of a standard solar power bank serves as an example. Notice that it requires a minimum of 25,000 LUX sunlight to charge via solar.
Wrong or broken charger/power cable
If you’re trying to charge your solar power bank using a USB charger and it isn’t charging, the issue might not be your power bank. It could instead be the charger or the cable. Make sure you’re using the correct charger, one that delivers the proper voltage and current (as required by your solar power bank). If it still doesn’t work, the charger (or just its power cable) could be broken.
Excessive battery drainage
We recommend that you recharge your solar power bank before you drain it completely. If you drain your power bank completely, it’ll require more energy to get going again instead of charging it from a 50% state of charge. As a result, if you deplete your solar power bank entirely, it might take even longer to charge with solar, or in a worst-case scenario, it might not charge at all.

How do I know if my solar power bank is charging?
Charge your power bank properly. Doing this ensures that it provides you with power when you need it.
Most Solar Power Banks on the market have four tiny LED indicators that flash progressively when charging. Although they may vary in size and color, you can quickly identify them on your Solar Power Bank. Advanced models display different LED colors to indicate the charging source. After reading the User Manual from a few different Solar Power Bank models, we’ve noticed that for most models:
- Blue LED: Indicates USB port charging
- Green LED: Indicates solar charging
Furthermore, the LEDs indicate the state of charge when the solar power bank isn’t charging (and the LEDs aren’t flashing). In this case, the lights represent:
- 1 LED on = 25% state of charge
- 2 LEDs on = 50% state of charge
- 3 LEDs on = 75% state of charge
- 4 LEDs on = 95%-100% state of charge
Logically, when fully charged, your solar power bank should have its 4 LED Indicators active. As it discharges, the indicators gradually turn off.
Because of the variety of models, you might find yourself with a device that indicates charging differently than the way we described.
For this reason, we strongly advise that you read your device’s user manual. There, you’ll find all the information you need, specific to your solar power bank model.
Ways to fix a solar power bank that won’t charge
If your solar power bank isn’t charging, don’t panic! Here are a few things you can try to get it up and running again:
Add extra solar panels
If you’re trying to charge your power bank with solar energy after draining it completely, it may not charge at all.
Why? The surface area of your power bank’s solar panel might be too small to generate enough electricity to get the redox reactions in the battery going.
In this case, adding extra solar panels might fix the problem. You can attach/connect small solar panels to your solar power bank (if it supports this addition) – you can easily find them online.
This will increase the solar input of your power bank until it recharges to at least 50%. After this point, the electricity generated by your main solar panel (without the extra ones) will probably be enough to continue charging your power bank.
Try charging it with electricity from a wall outlet
As mentioned above, your power bank might be too drained to start recharging only with the small energy input the solar panel provides. If this happens, don’t give up on your solar power bank just yet. Pumping up some juice from a wall outlet might bring it back to life.
Place it in direct sunlight for an extended period
Solar Power Banks can take over 50 hours to recharge using solar energy. Considering how many hours of sunlight are in a day, it could take an entire week to recharge your solar power bank.
For this reason, it may seem like it isn’t charging, when in reality, it’s just taking a long time.
To maximize sunlight absorption and overall efficiency, one way of speeding up this process is to place your solar power bank in direct sunlight for an extended period.
Check for any loose connections
A more elaborate way to fix your solar power bank requires some skills. If you have previous experience repairing electronics, you could try opening your solar power bank to check for any fraying or loose connections.
For instance, your solar power bank might not be charging because the wire that connects the solar panel to the circuit board is loose.
In this case, using a soldering iron to solder the loose wire will fix the broken.
Check if the battery is dead
This one also requires exposing the inner pieces of your solar power bank.
Depending on the battery’s chemistry (and its nominal voltage), you can tell if it’s dead by using a voltmeter to check its voltage.
If you conclude that it’s dead, the only way to fix your solar power bank would be to replace the battery. This procedure might not be cost-effective, so do your research before buying a replacement battery.
Here’s a little tip: You can also use the voltmeter to measure the output voltage of the solar panel. Maybe the battery is fine, but the solar panel isn’t generating any electricity.
If you’ve exhausted all your options, and cannot find a way to fix your solar power bank, it’s time to invest in a new one.
