Thoughts, stories and ideas.

A solar power bank is a small, portable way to bring electricity wherever you go. They also come with built-in solar panels to give you an off-grid option for recharging your power bank when outlets are not available. They are usually around the size of a cell phone and are a perfect way to meet your power needs, whether you are on a camping trip or hiking in the mountains.

Most solar power banks are similar in design but vary in their amp-hour charging specifications and battery capacity. When you are looking for a power bank for your outdoor fun, make sure you know what devices you will be charging and how much power you need in the minimum amount. That way, you will always have enough charge to do the job without disappointment or frustration.

Power banks come in varying degrees of quality with silicone, ABS, or PV materials. They often have extra features like flashlights or a compass. Make sure the quality extends to these extras if you plan to use them or not. The extras can give you the advantage during an emergency, but also give you a way to be safe in case there are problems like getting lost.

What Should you Consider when Purchasing a Solar Power Bank?

Before you buy a solar charger, know how much power you will need to get a good estimate on your power needs. The type of charger you buy needs to meet your power needs and provide you with enough backup power in case of problems.

Solar Power Banks vs. Solar Chargers

Solar power banks are banks of stored solar energy you can use as you need. The banks store energy through solar panels that direct electricity into your batteries for later use. Depending on the type of system you set up and the number of solar panels you have, you can generate a small to a large amount of energy into your power banks.

Solar chargers typically are more portable options for charging your devices. They are smaller than power banks and can help you keep your devices charged wherever you are. They come with built-in solar panels to charge your devices without storing large amounts of power to use later.

Expecting to charge using only solar panels

Depending on the type of system you assemble, you can charge everything using solar panels off of a solar bank. The system only works with a large number of solar panels that most people do not have as they travel. You should not expect to be able to charge your devices completely using solar panels through your solar panel bank.

It can take hours to charge a power bank, so you will need to supplement your solar intake through an external hookup to your house or vehicle. You should choose the devices to charge using your solar power bank that is lower power draws or that you do not need to charge as frequently as other things.

Milliamp-hour measurements in battery capacity

Part of having a solar-powered battery storage system is knowing how to calculate your intake of solar and rate of discharge. Your batteries can store around 2.5 times more electricity than the ten thousand Ah power bank. You can measure your batty capacity by adding your measurable amp-hour storage in all of your devices and multiplying that by how often you charge them. That number is the amount of power you regularly need to meet your device power needs and see if it matches the capacity of your system.

Solar power banks can hold up to twenty-five thousand measurable amp-hours depending on the type of bank. The more amp hours your battery has, the more power your battery bank can store. For perspective, if you have a twenty-five thousand amp hour battery, you can charge your iPhone X about nine times because of the 2716 amp hour battery. You need to note how much power all your AC devices pull so you can know how much DC power your system can put out.

Water-resistant vs. Waterproof

Water-resistant devices are different than water-proof. Water-resistant means your power bank can withstand small amounts of moisture from dew in the air to small showers. You will need to dry that power bank before use to prevent damage completely. When you are looking at power banks, you will need to make sure which type of water-resistance your power bank has.

Water-proofing or water-resistance is in the IP ratings on the devices. There should be two numbers to interpret with the higher the IP rating, the more waterproof the device is. The numbers denote how much waterproofing the device has with an IP67 device indicating resistance to damage if submerged in one meter of water for up to thirty minutes (the seven shows this). Make sure you read other people's reviews to make sure the reading is correct because water-resistance is not water-proof.

Final Thoughts

Not everyone needs to charge their devices on the go, but have a solar power bank can help you when you are in need. They are an excellent item to have when you are traveling off-grid. They are ideal for camping or hiking when you are away from power sources to keep your phones and tablets going.
