A Review of 5 of the Best Solar-Powered Power Banks

The world is moving towards green energy with every new discovery. Now, we have electric cars and renewable power generators. Energy storage devices are shifting, and power banks offer a front row seat to green-energy use.

While aiming to leave no carbon print behind, solar-powered back-up energy storage devices enter the market each day.

If you have ever been in a situation with a dead phone, no electricity, or an alternative source of power, then this piece is for you.

Below, we discuss five of the best power banks you can use with a wide range of devices, at home or during your traveling escapades.

Solar Power Banks Buying Guide

The standard power banks just don't cut it nowadays. This is because you need to have electricity to charge them, which negates their role.

On the other hand, the introduction of solar power banks revolutionized the industry. Wherever you are, you only need some sunlight, and you can charge your phone. The best part is that you can get these solar power banks at affordable rates from many stores.

However, before you buy your power bank, you need to understand a few things about solar power banks and how to buy them.

What are Solar power banks?

This is an electronic device that harnesses the power of the sun to generate electricity. The energy created in the solar panel is then stored in a battery fitted in the power bank's build or directly used to charge your phone.

The power bank consists of a solar panel, which converts the sunlight into energy.

Since you can always find sunlight anywhere, these power solar power banks are convenient for outdoor activities or areas with unreliable power supply.

What to consider when buying a solar power bank

Before you order or buy a solar battery pack, you must assess its properties. This way, you have a pretty clear idea of what you are getting.

Below are some factors to consider when purchasing solar power banks:

Charging time

When buying these backup battery packs, it is always better to go for one that offers fast-charging capabilities. To understand this, you should consider the cable used to charge the device and your phone. Generally, micro USB cables tend to charge faster than the average USB cables.

How long does it take to charge fully using solar?

The goal of having a power bank is to have reliable and accessible power to charge your phone in unsuitable conditions. So, when buying a solar power bank, take note of the time the device takes to charge fully on solar power only. If the period is too long, look for an alternative.

It would also be best if you found a solar power bank that allows for multiple charging methods-maybe direct electricity and using solar, for versatility.

Battery Capacity

The regular unit for battery capacity is mAh, meaning milli-Amperes. This indicates the amount of power the battery can give at full capacity.

When buying a power bank, go for one with a larger capacity. The larger the capacity, the fewer the charging cycles, hence less catalyzation, which translates to your power bank's longer life span.

Also, the high-capacity power banks can charge your phone multiple times before depletion, making them reliable.

Size and weight

When buying a power bank, you are aiming at a portable energy storage device. So, it is only fit to get a compact-sized and light-weight power bank.

You should get a power bank that easily fits into your bags.

A larger power bank is more likely to break if not stored properly.

Also, make sure that the battery and solar panels attached to the solar power bank do not make it too heavy for your convenience.

Remember, there is always a better option. If you get a bulky power bank, you can exchange it for a lighter one that is more suitable for your activities.

Durability

Solar power banks are for outdoor use. You carry them along when you go hiking, on road trips, or even camping. For all these conditions, you are bound to interact with harsh weather conditions.

You could experience hot days, rainy days, and windy conditions.

A good solar power bank will prevail in these conditions. They should be resistant to wear, tear, and water.

Also, check the maximum temperatures the solar panels can experience before they start breaking down. The higher the allowance, the more versatile your power bank will be.

Look out for additional features that make it easier for you to use your solar panels. These could include buckles to strap them into your bag packs or harnesses to hold the solar panel in place as it charges the battery.

Outputs

Your go-to solar power bank should accommodate multiple charging ports. This way, you can charge more than one device simultaneously.

Most models come with two standard USB ports. However, some advanced options have Type-C ports and Qi-wireless for phones that allow wireless charging.

The more output options you get, the more compatible it gets.

Safety features

A good solar power bank is one that is safe to use. And this goes both ways, meaning it should be safe for your phone, tablet, or laptop, and also the power bank.

While the safety features in place should protect against over-voltage in your electronic device, it should also protect from over-charging, which could damage the power bank.

Always go for a power bank that protects your devices from over-current, overheating, overcharging, and short-circuiting.

FAQs About Solar Power Banks

Can you charge solar power banks with regular outlets?

Solar power banks are constructed with the solar panels as the back-up power source. That means you can use the regular power outlet to charge it. And when you are not near a reliable power outlet, you use the solar panels to charge the power bank by harnessing power from the sun.

What is Qi wireless charging?

Qi wireless charging is a modern technology, which allow you to charge your smart device without the use of a charging cable. It uses a concept known as inductive charging, where charge is transferred to the battery in your device through magnetic waves.

It uses a transmitter (Fitted in your power bank or charging pad) that sends the electromagnetic waves to your phone. The receiver (on your smart device) then receives these waves and converts them to electrical current, which then charges your battery

How long does it take to charge a phone using solar power banks?

The time taken to charge your phone with power bank depends on several factors. These include:

• • Model of phone- Older phones take longer to charge, compared to smart phones that have fast-charging capabilities
• Cable used- micro USB and Type-C cables are the best bet for fast charging. The regular USB 3.0 cables tend to increase the charging time
• Charging ports on the power bank also determine the charging time

How many hours does it take to recharge a power bank?

Despite their fast-charging capabilities, solar power banks serve as back-up power supplies. This is because they take an average of 25-36 hours to recharge in the sun. Others take as long as 75 hours to charge completely using solar.

However, they also store the charge for longer, meaning you can use some models for as long as 5 days without recharging.

Is my phone compatible with solar power banks?

When you decide to get a solar power bank, you must select one compatible with your device. This is a necessary measure to prevent wastage of your hard-earned cash.
