What is a solar power bank and how does it work?
Solar power banks are small external batteries that can be charged with solar energy and allow you to recharge without having to connect them to an outlet. Note that you can charge them by plugging them into a power outlet as well as with solar energy. They are normal power banks with solar panels.
Advantages and Disadvantages of Solar Power Banks
Using a power bank comes with several benefits. The biggest pro of using one of these gadgets is that you will be able to charge your electronic devices without being near a power outlet. This way, if you are in nature and need to charge your phone, for example, you will be able to do so. However, it is important to note both the pros and cons of any product you may purchase.
Advantages of Solar Power Banks
- You can charge your devices without plugging them into an outlet.
- It allows you to charge your devices in nature.
- Their small size makes them easily portable.
- They are very easy to use.
- You can charge them by plugging them into an outlet or with solar energy.
Disadvantages of Solar Power Banks
- They charge slowly with solar energy.
Shopping Criteria for Solar Power Banks
If you’re considering buying a solar power bank, you need to keep a few shopping criteria in mind that will help you make the best choice. To help you, we have selected some of the most important factors to consider when choosing exactly which solar power bank you want.
- Size and weight
- Charging capacity
- Charging speed
- Battery charging time
- Number of connections
Size and Weight
The size and weight of this gadget are both very important criteria to consider when choosing the perfect solar power bank for you. Keep in mind that you will be carrying this wherever you may go, perhaps for multiple hours, especially if you are camping or hiking. You are going to want a portable, light, and small model.
However, do not forget that the heavier your solar power bank is, the more room it usually has. Think of your priorities: Do you prefer a light power bank with less charging capacity or a heavier power bank with more charging capacity? The choice is yours, but don’t worry; most of these items are very light.
The charging capacity of a battery is measured in milliampere-hours (mAh.) You can currently find models on the market that have a charging capacity of up to 50,000 mAh. Keep in mind that a cell phone usually is not higher than 5,000 mAh, while a tablet does not exceed 12,000 mAh.
To understand how quickly the solar power bank you purchase will charge your device, you should look at the voltage and output amperage. The voltage should be around the same as the charger of the device you wish to charge. If you are thinking of charging your cell phone, 5 volts (V) should be sufficient.
The second factor in this section that we want to mention is output amperage. The higher it is, the faster the solar power bank will charge your device. The majority of power banks that you will find on the market generally have an output amperage between 2 and 3 amps (A).
Battery Charging Time
You must know how fast the solar power bank that you purchase will charge itself with solar energy or plugged into an electric current. Keep in mind that when you charge this gadget with solar energy, it will take much more time—often more than 24 hours of direct sunlight. The time it takes to charge when connected to an outlet will also depend on its voltage and output amperage.
You are probably going to take your solar power bank with you when you are hiking or camping. If this is the case, there will always be the possibility of damaging the battery. You may accidentally drop or otherwise hit the battery. This is why you should choose a power bank that has strong resistance.
If you are planning on hiking in the rain, it is also important to get a waterproof power bank. You may want to consider purchasing a model that is dust-proof as well. Keep in mind that if you buy a waterproof battery, this does not mean you can submerge it underwater. Finally, be sure to buy a battery that is made of high-quality materials.
Number of Connections
The last aspect that you should consider is the number of connections that your solar battery has. This will determine how many devices you will be able to charge at once. You also need to note what type of connections they are. You may find USB or micro USB connections, among others.

Who should use solar power banks?
Solar power banks are great for nature lovers, especially for long trips without the reliable availability of outlets to charge your electronic devices. This way, you will be able to take your phone or laptop with you and charge it wherever you are. This can solve many potential problems.
When might I need a solar power bank?
Solar power banks are very useful if you are going to spend an extended period of time away from a source of electricity. This may be out at a music festival, camping, hiking, or on a plane, bus, or anywhere else you might not find an outlet to charge your electronic device.
What are the solar panels made out on solar power banks?
Solar power banks are made up of one or various solar panels that are built from small photoelectric cells. These cells can be made up of high-quality monocrystalline or polycrystalline silicon. We recommend power banks with monocrystalline photoelectric cells, as they usually work better.
How should I charge my solar power bank?
We generally recommend that you charge your solar power bank by plugging it into an outlet because charging it with solar energy will take much more time. This is because the solar panels are very small. Most manufacturers recommend charging this gadget with solar energy only when you do not have access to electricity.
What is the difference between a solar power bank and a solar phone charger?
Both solar power banks and solar phone chargers have a similar function: They allow you to charge your phone without having to plug it into a wall outlet. However, solar power banks are portable batteries and can store the energy collected from the sun or an outlet.
On the other hand, solar phone chargers only transfer the energy directly to the electronic device that it is charging and cannot store this energy. In this sense, solar power banks are more useful.
