best solar power bank

When your phone battery dies because you forgot to charge it, you rely on a power bank. But what happens when you forget to charge both? Or have you ever thought of a situation when both your phone and power bank is dead due to several days long power cut? Or do you have any backup plan to charge up the phones during a campaign? 

Well, there is a solution to all these emergencies. That is, using a power bank that charges itself. To cope with these situations, solar-powered power banks have launched in the market. Other than getting recharged by sunlight, there are other useful features of these power banks. Read ahead to know more about solar-powered power banks; I am sure it will not fail to amaze you. 

What is it

We all know what a power bank is; it gives backup when you need to charge your small and smart devices but you are not near any power outlet. Nowadays it is as compulsory as electricity, or for some, as necessary as air. However, it is useful not only to power up a smartphone and mobile phone, but also GPS, flashlight, camera, and any other handy devices. 

A solar-powered power bank is also a power bank too but it has a solar-powered recharging option. Some solar power banks have type C input to recharge from any power outlet. Though the solar panel takes a long time to fully charge the unit, it is yet handy for emergency situations and outdoor.

Why You Need One 

Maybe you already have a conventional power bank and you are satisfied with yet, still, I will recommend having a solar power bank. These are meant for outdoor use mainly so these are made shockproof, dustproof and waterproof. So, these power banks are more long-lasting. 

Besides, almost all solar power bank has flashlight, some have lighter, or compass and other additional accessories to use in emergency situations like a regular power cut or hurricane, etc. I can bet, your power bank won’t stay up long when you have to survive off-grid. But if it is a solar power bank, it will still be able to charge your compulsory communicating devices for several days. For these reasons, even if these kinds of power banks are pricier, I think if anyone wants to buy only one power bank, he/she should invest in a solar power bank.

It has 2 ports of 2.1A and 1A to charge two smartphones simultaneously. With additional USB ports, you can use up to four old fashioned phones with this power bank. It’s charging rate is as good as using a smart charger in the main grid line. However, the power bank is a high capacity one, hence it takes a long time to charge the batteries fully. Depending on the sun, it can take up to a week for a full charge. 

The additional features include a bright flashlight and an LED indicator to show the state of charge and power. Using this power bank is super easy, the power button does all the job to power on, off, turn on the LED, charge the battery, etc. its customer service is praiseworthy.

With its USB input, you can charge other devices as well that are not Qi-compatible.

This unit has all the facilities of highly-priced power banks, within half the price. It can charge up to 2 devices whether it is a mobile phone, camera, GPS, etc with its 2 input. The power bank will stay usable even if you drown it underwater for half an hour. That makes it a great choice for people who love to kayak or dive while trekking or hiking.  

There is a compass keychain that included with the package. The compass is not the professional quality one, but still helpful for emergency situations. Like other power banks, the flashlight has 3 modes to choose from. 

Its long battery life and multiple circuit protection make it convenient even if it is cheaply priced. The grips at the sides of this device make it comfortable to hold and prevent slippage. A built-in hook is attached to the corner of the power bank so that you can hang it from your backpack and let it bathe in the sun. however, the little details are important to realize, how carefully this device was designed.

This power bank doubles as a general power bank and a solar-powered power bank. Its power output lets you charge it before use. Make sure you charge it fully before leaving home. Charging it with solar power may take days but when the charge is full, it can power up your devices without any hassle. For emergency situations only, use the solar power option. 

The makers have made attractive policies, worth to keep this power bank on our list. You can contact the customer service 24x7 upon any dissatisfaction regarding the unit. Besides, you can also replace it for any major problem. 

The thing I love most about this power bank is its smart detector. The detector detects the requirement of the device you want to charge by it. Then, it adjusts the current from 1A to up to 2.1A regarding the requirement. This method prevents overcharging your valuable device and minimizes any confusion about which device to charge from which input and vice versa.

If you are intending to buy a solar power bank, then let me assure you that, you will never find any power bank with panels larger than this one. It has 3 regular sized solar panels that are foldable when not in use. In fact, you can detach the power bank part from the panels whenever you want to. Larger panel meaning the device charges 3 times quicker than other solar-powered power banks. 

However, this power bank can be charged from a power outlet; so, recharging this power bank is never going to worry you. Now, you don’t need to charge your power bank with power cable as the solar panels are good enough to do that job during the day. For at-home use, to save yourself from dead phones during a power cut, simply keep the power bank hanging from the window where it can take sunlight. Later, use it when necessary. For outdoor use, keep it attached to your backpack with all the panels exposed to the sun. by the night, it will be ready to charge all your devices. 

With its Qi and 2 USB outputs, you can charge 3 devices simultaneously. No matter which device you charge with it, its smart device detector ensures that the charging will be done safely, without causing any damage to the device. As it has 3 solar panels instead of one, the price is a little higher side. 

Pros

  • Large panel;
  • Can charge up to 3 devices;
  • High capacity.

Cons

  • Pricey.

It is the highest capacity solar power bank on this list. Usually, the larger the capacity of the device, the longer it takes to charge. That won’t happen with this power bank. Because you can charge it via USB before heading for camping or so. Once, it is fully charged, then leave it in the car or close to the window of your living room; you may don’t need to charge it again. The device will charge itself through the sun. 

This unit comes with a bright flashlight that can be adjusted in 4 different modes. Use it according to your needs. It has a waterproof, sturdy feature that makes it perfect for outdoor use in hiking or trekking. Charge any smartphone or any other device you have to stay prepared for any emergencies. 

Its large solar panel makes the entire unit a bit bulky. Note this before you make the decision to purchase it. For me, the size didn’t matter as it does the job just fine. 

Pros

  • High capacity;
  • 2-way power up design;
  • 4 mode flashlight.

Cons

  • Bulky.

Everyone is not a big fan of camping or trekking or any other outdoor activities that require surviving outside of civilization for a long time. Those people also need a solar power bank just to survive an emergency during a power cut or just being forgetful to charge the power bank they use regularly. In these cases, high capacity and pricey power banks are not necessary. A small-capacity power bank with a limited capacity will easily fit your budget while fulfilling all your needs as a power bank. 

It is a small, compact-sized power bank that can be left in the car, or on a cabinet to let it stay charged. So that you can avoid a dead phone after a long busy working day. It is budget-friendly as well, a good option to start your solar power bank experience for the very first time. 

Pros

  • Compact and small;
  • Cheap price;
  • 2-way charging design;
  • Charges 2 devices simultaneously.

Cons

  • Limited capacity.

Usually, the small capacity solar charger power banks don’t have the power charging feature. But this model from Zonhood has all the features of a pricey high capacity solar power bank within a fraction of the price. It comes with 2 models, the blue and orange ones are conventional power banks with solar charging capacity and the red one is more resistant, suitable for outdoor use and comes with a lighter. 

I recommend this one for customers who are looking for a cheaply priced power bank. Its sturdy construction and functionality worth every penny you spend on it. 

Pros

  • 2-way recharging options;
  • Budget-friendly;
  • Long-lasting.

Cons

  • No cons.

To save space in your backpack and to reduce some weight of the bag you are carrying, a small and lightweight power bank is your only option. It will charge your phone battery as other power banks do, but weight and priced lesser than those. It is a small capacity power bank but can be charged via a power outlet. The good thing about the small capacity power bank is, it recharges quickly whether you power it up via power outlet or sunlight. 

Unlike other power banks I have reviewed, there is no LED attached to the unit that will run on the device battery. Instead, a mini LED is included in the package that runs on battery and can be used for emergencies only. 

Pros

  • Anti-skid;
  • Compact and lightweight;
  • 2-way charging and 2 USB ports.

Cons

  • Low capacity.

Buying Guide

Compared to electric power banks, solar-powered power banks are very expensive. It is better to take caution while purchasing one. Otherwise, you may end up purchasing one that is too powerful to your requirement and unnecessarily pricey. On the contrary, you may invest in one, that is not sufficient for you. Here are some guidelines that will help you out to take the right power bank for you. 

Construction

Mainly, solar power banks are made for outdoor and emergency use. Hence, all the power banks have rugged and tough construction and are made dustproof, waterproof and shockproof. Yet, some have grips to make it anti-slip and some have padding on the back to make it anti-skid. The anti grip ones are good for camping and the anti-skid ones are for home use when you have a sleek surface to charge your devices. 

The second thing you should look for is its size and weight. For trekking, the lighter and smaller is the better, even if the capacity is low. But for home use during a power cut, the bulkier is the better for the larger solar panel. If you really need one that is high capacity, then look for the one that has multiple solar panels. These are great for long term backup. 

Recharging options

There are two types of solar chargers available in the market. One, that doubles as an electric power bank and can be charged via power outlets as well. The second one has only solar recharging options. Both are functional for different purposes. For example, if you have the first one, you won’t need an electric power bank. So, it is more economic. 

On the other hand, the power bank that is dependent solely on sunlight is great for backup solutions. If you are forgetful to charge your power bank after use, then you must have a solar-powered power bank. It charges itself, just hang with your backpack or the car window. You will always have a power bank that is ready to serve!

Charging Outlets

Most of the solar power banks have 2 USB outlets. Some have two outlets of 2.1A capacity and some have one 2.1A and another 1A capacity outlet. Both of the outlets can be used at the same time.

There is another kind of power bank that has Qi wireless charging option. With this, you can charge up to 3 devices at once and the Qi option works faster than USB. the thing is, you have to have a device that is Qi-compatible. 

Additional Features

All the solar power banks have one or multiple flashlights with different modes. Look for this feature if you are intending to use it during camping or hiking. Keep in mind that, the lights will run on the power bank battery and can be used for a limited time. 

Some power banks have a pocket compass included. It is better to invest those models if you don’t have a professional compass yet. All the power banks come with a hook so that you can hand it from anything.

Customer Support and Warranty

Always look for reviews of their customer support. Surprisingly, I have found almost all the manufacturers of solar-powered power banks have excellent customer care services. Next, check the warranty, refund and replace options before you order one.  

How to Make the Power Bank Last Longer

No matter how good the power bank you have purchased, it is possible to get a bad service from it if it is not used properly. Purchase or not, don’t miss the following tips on how to use and how not to use a power bank. 

Disconnect when it is Full

Always remember to disconnect the power bank or the device use are charging when it is full. Otherwise, the battery will be damaged sooner if the power bank is plugged in with a power outlet. If the phone is plugged in after a full charge, the power bank will drain the phone battery and will keep recharging itself. 

Don’t Leave it in the Car

Read ‘don’t leave it in the car, exposed during summer’. Because the excess heat can overheat the power bank and ruin its quality. A car is the second most favorite place to keep a power bank. This way, we can recharge it via the sun, and charge phones while driving. Remember to transfer it to the glove compartment When it is charged fully. 

Conclusion

Power banks became our basic needs from the day we started depending on our smartphones to survive in modern society. This small rectangular device is a lifesaver when you have to step out of the civilized area, or during a long term power cut or any other worse situation. That’s why choosing a power bank that suits you is important to ensure its usability on a daily basis or in emergencies. As you have come so far in this write-up, you now know the types of solar power banks available in the market, how to choose one that will serve you properly and how to make them last longer.
