A Smaller Solar Panel For Charging Phones

Sometimes you need to charge your devices when the sun isnât out, which is why are a great addition to any solar panel. This smaller one is great for taking with you on car trips, since it weighs less than 5 pounds and can hold enough power to recharge your phone 16 times or recharge a light for 10 hours of use. It has a 167-watt-hour lithium-ion battery pack, and it can be recharged with a SolarSaga 60 in just 4.5 hours. Or, you can pre-charge it at home with the DC port, then use the two USB ports and one USB-C port to charge your devices.

One fan raved: âAfter reading a number of reviews I had buyers remorse. I wanted to find something wrong with it and couldnât. Mine came 38% charged so it took a few hours to fully recharge. Then I charged my iPhone and my Bluetooth headset. It was at 95%. The next day I charged my iPad and a portable DVD player. It was 87%. The next day I charged my iPhone, iPad, and an android phone. Then I charged another iPhone using the AC output and another device using the 12V output and a car charger. I finally ran it down to 20% before recharging it. Itâs a work horse. Iâm looking forward to using it camping and car trips.â

Pwm Solar Charge Controllers

Best Solar Power Chargers

PWM solar charge controllers have a direct connection from the solar array to the battery and use a basic rapid switch to modulate or control the battery charging. The switch is open until the battery reaches the absorption charge voltage. Then the switch starts to open and close rapidly to reduce the current and maintain a constant battery voltage.This in turn pulls the panel voltage away from its optimum operating voltage and reduces power and efficiency.

PWM solar charge controllers are a great low-cost option for small 12V systems where one or two solar panels are used, such as simple applications like solar lighting, camping and basic things like USB/phone chargers.

Protecting A Solar Charger

Why you need a solar charger controller

Many solar chargers were made initially for the business travel market. While these are robust enough to survive airports, hotel and office use, they are not normally intended for backpacking and other outdoor pursuits. Fortunately, there are now many chargers with far more rugged designs that are geared specifically towards this outdoors market, and even more robust normal use by construction workers, students, and others with these requirements.

Charge Completely And Often

Youve probably heard at least once, if not a million times, that you shouldnt charge your rechargeable batteries until they are completely dead. Where this was true about old school rechargeables, it is actually the opposite of what you should do for lithium-ion batteries, like those on our list. These batteries will in fact degrade faster the more often you let them run completely dead. It is much better to recharge them more often before they completely discharge.

Key Specs For Portable Battery Packs

Storage capacity: This tells you how much charge the battery pack can store for use later to recharge your devices, before it in turn needs recharging.

Tip: Transferring energy from one battery to another is not 100% electrically efficient. Thus, a power pack rated at 2000 mAh will not fully recharge a 1000 mAh electronics battery twice.

To recharge or top off your electronic device, you need a battery pack with enough storage capacity and enough output voltage to move energy into your device.

How much is enough? Find out the storage capacity of the battery in your device. For electronics with built-in batteries, check the technical specs to find the battery capacity. If your device uses only replaceable AA batteries, this is not an issue. Choose a battery pack that features these.

Power output: The output of the charger must be equal to the input battery voltage requirement of your electronic device. If its lower, you may drain your devices battery instead of charging it up. Oops!

Most portable battery packs will charge small personal electronics like cell phones and mp3 players, but relatively few can recharge a laptop battery.

Small electronic devices that can be charged with a USB cable need a 5V output rating. Larger electronic devices that require a DC power input may need a 12V 24V output rating. This is available from the largest portable battery packs.

Gather And Store Solar Energy

Products from Element5 Solar will assist you in gathering Energy out of sunlight and storing this energy for later use.

You can then use this energy to power electronic devices, light up rooms through LED technology

or just keep it as backup energy for emergencies.

The Solar Module on your solar bag will transform sunlight to energy when exposed to the sun. This happens through a so-called photovoltaic process.

Energy is best harvested in bright sunlight, but the technology in our solar panels also allows for charging under cloudy circumstances and occasional shade that the module may be in.

A battery, specially designed for solar purposes, will store your generated sunlight as electricity within your bag or next to your solar kit.

It is essential to store your transformed sunlight in a special battery before you use it for your phone or tablet, as it is safer for your device

and more fun for you to use.

The battery will filter any energy peaks or lows coming from the solar panel in changing conditions. Also, it will act as a buffer for energy, making sure your devices get all the energy they need in one single charge and at exactly the voltage they need. Some of our batteries even count your energy production and will give you a feedback on your yield.

Solar Power Banks Vs Solar Chargers

When looking at solar power banks, youve probably seen a lot of names and buzzwords thrown around, like solar power banks, power packs, and solar chargers. Manufacturers sometimes use muddled lingo, making it hard to figure out exactly what youre looking at. Lets set the record straight on what these terms mean.

Solar power banks, also called solar power packs, include a solar panel integrated into a portable battery. This can be a single solar panel or multiple panels that fold out, but its always a single unit. The type of solar power banks featured on our list are small and designed to charge your smartphone, tablets, and other small devices. As weve seen above, the solar panels are typically too small to fully charge the battery and are instead used as a backup charging option. Its generally best practice to charge your solar power bank at home before you leave.

Solar chargers are also designed to charge your phones and tablets, but only include the solar panel, not a backup battery. The solar panels are typically larger than those on solar power banks, 5 to 25 watts compared to power banks 5 watts or less. With the large solar panel, solar chargers can keep your smartphone and tablet fully charged indefinitely, but only during the day when the sun is out. Solar chargers are the perfect option for long trips when outlets arent available backpacking trips, weeks spent camping, etc as theyre lightweight yet powerful .

Dont Expect To Charge Exclusively With Small Solar Panels

This might be a bit of a shock to you, but most of the solar power banks above cant really be charged by their solar panels. Yes, its a bit sad and confusing, but its true. The solar panels are simply too small to fully charge the batteries in a reasonable amount of time. Most manufacturers say itll take about 40 hours to fully charge the battery via the solar panel. Yikes!

Instead, consider the solar panels as auxiliary or emergency charging. They can keep your battery pack topped up when youre on the trail or running around town, but thats about it. All the solar power banks above can be charged via a wall outlet in just a few hours with the included USB or micro USB input, so youll want to fully charge the power bank at home before leaving for any adventures.

If you want to keep your smartphone or tablet charged completely via solar energy, you have two options. You can use a larger solar charger instead of a solar power bank, but remember, this will only allow you to charge during the day. If you want to have a battery backup and use exclusive solar power, you will want to invest in a battery pack that can be connected to a larger solar panel.
