Solar power banks are the ideal travel companion for individuals who want to go on extended trips without access to modern amenities like electricity.

You’re not alone in asking how you’ll charge your mobile devices if you’re contemplating this kind of expedition. Fortunately, there is a valuable piece of equipment to keep you completely powered up: the solar power bank.

The solar power banks market is expected to increase at a CAGR of 12.3% between 2021 and 2028. The global market for solar power banks reached $5,635 million in 2017 and is expected to reach even higher levels by 2028.

To use a solar power bank, place it in direct and unobstructed sunlight for several hours, which will charge its battery.

After that, you can plug in a battery-powered device, and the power stored before will be transferred from the solar charger’s battery to the phone battery.

You’ve come to the right page if you want to understand the fundamentals of solar power banks. So, let’s get started!

Read the User’s Guide

First and foremost, just like any technological purchase, you should read the user handbook. Even though power banks are simple to use and you may wish to pull them out, be cautious.

Ask yourself some simple questions like, “How do I maintain my solar power bank’s battery capacity, efficiency, and technical capability?” The user handbook has all of the operating instructions.

Charging the Power Bank

You may constantly recharge your power bank using two different sources: electricity and the sun. The number of solar panels on the power bank will give you an idea of how well it will charge in strong direct sunlight.

Let’s suppose there’s only one solar panel on the power bank’s face. In this circumstance, charging your power bank using sunlight is likely to be a backup power source rather than your regular electricity supply source.

In other words, don’t anticipate power banks or solar chargers to be charged up after a few hours in a safe and bright spot. It’s more probable that the equipment will occasionally rely on power outlets to recharge itself.

Conversely, if you have a power bank with a lot of monocrystalline panels, your battery bank should be able to be charged entirely by the sun’s energy.

Using the Power Bank to Charge Devices

It would be best to charge your gadget with your solar power bank once it’s fully charged. To accomplish this, connect the solar power bank with your charger’s USB outlet, and plug the other end into your device.

Look for multiple USB ports on the surface area of your power bank if you want to charge multiple electronic devices simultaneously. The amperage output of your ports is something to keep in mind.

Check to see if the charging ports you’re using to charge your phone are just 1 amp. 2 amps are too fast for phones, which may shorten their battery life over time. To learn more about this, consult the user manual.

How to Know When My Power Bank is Fully Charged?

A light indication on power banks usually indicates how well charged they are.

  • 4 Lights = 95% charged
  • 3 Lights = 75% charged
  • 2 Lights = 50% charged
  • 1 Light = 25% charged

Due to the fact that most power banks do not provide 100% readings for security purposes, you mustn’t overheat your power bank. Ensure that you replenish your power bank with enough power before it runs out.

When a power bank is entirely depleted, it takes more energy to get it going again than when a solar power bank is charged from 50%.

How to Keep Your Power Bank in Good Working Order?

Purchasing a high-quality solar power bank might cost hundreds of dollars. You will get the maximum benefit from your investment if you maintain it appropriately.

The following are four guidelines for making your solar power bank work efficiently:

  • It should not be overcharged
  • Keep it cool; any significant increase in temperature may shorten the life of your power bank’s battery. The ideal temperature range is 77°F to 86°F.
  • A short length USB cable can be used to charge your mobile phone
  • If you aren’t using it, charge your solar power bank to 50% capacity and store it

How Long Do Solar Power Banks Take To Charge?

The amount of solar panels on your power bank determines how much energy you can retain. The photovoltaic cells in a solar panel convert sunshine into electricity; therefore, the more panels you have, the sooner it will charge.

A solar power bank with a capacity of 25,000mAh may be charged by the sun alone in about 25-50 hours. This is assuming that the weather is suitable, i.e., as much direct sunlight as possible with no overcast.

Solar Power Bank Battery

Is it Possible to Use my Phone while the Power Bank is Charging it?

You may charge your solar power bank while using your phone. In most cases, though, this leads to the battery being in series or line with the phone. This results in a more considerable drain of your phone’s battery capacity, leading to overheating and battery damage.

This is not a good idea. Do it only if you have no other option. Discover what your manufacturer suggests by reading your manual. They usually know how to utilize a solar power bank to its full potential.

Precautions to Take When Charging Cell Phones Using Power Banks

Despite their size, solar power banks are complicated devices that incorporate various kinds of electronics in a tiny space. They should not be discharged and charged at the exact moment, especially when using solar power.

Most manufacturers warn consumers against solar charging their mobile gadgets when using solar power banks in direct sunlight.

This may be acceptable for solar chargers that do not have a battery pack. However, it is not recommended that solar power banks charge the solar panels while a phone is being charged.

The solar power bank must not be exposed to water spillage or submerged in water due to all the wiring involved.

When mobile phones are being charged and the current moves through a circuit, this is even more crucial. Water-resistant power banks may be an exemption, but they should still be kept away from water.

Most solar power banks have an electrical sensor that interrupts the circuit and turns off the charging when the battery reaches 100%. However, after the power bank is fully charged, it is recommended that you unplug it and turn off the power button.

Always attempt to keep your solar power bank at least 50% charged. A fully charged power bank will ensure that your phone is charged at the fastest possible rate.

Avoid storing a power bank in an idle state for long periods, which can shorten its longevity. It’s a good idea to discharge and charge your solar power bank even while it’s not in use.

Parting Note

With the burgeoning renewable energy and solar power potential around the country, solar power banks are typically highly durable and weather-resistant, making them long-lasting and cost-effective.

Using the sun’s direct light hitting a power bank to charge is a sustainable and environmentally friendly way to ensure your device is always charged.

Understanding how to employ a solar power bank will make your off-grid excursions much more enjoyable. And in some circumstances, it could even spare you a lot of hassle!
