Top 12 Solar Battery Chargers
Posted by admin on
Finding yourself at an important event like a wedding, graduation, sporting event, or childs school play with a phone or camera that has gone dead is inconvenient. Its disappointing to not capture those photos.
But finding yourself stranded on the side of the road, in a city-wide blackout, or in the middle of the wilderness without power for your cell phone can be life threatening.
To prepare for those times when you need a little power but dont have access to electricity, you need to have one of the top 12 solar battery chargers weve listed below.
How Do Solar Power Chargers Work?
Before you can go shopping, its very important to understand how solar battery chargers work. Without at least a basic understanding of how these handy little devices harness the sun and produce power, you will likely purchase a charger that wont meet your needs.
A solar panel captures the energy from the sun and sends it through wires to your device as direct current (DC) power. Anything battery powered or that plugs into the wall with an AC adapter can use DC power.
This means you can potentially hook your device directly to your solar panel to charge it. Whether or not you can sufficiently charge these devices with just 1 solar panel depends on the efficiency of the solar panel, how much direct sunlight you have, and the voltage or amp hours being produced.
Its very difficult to rely on a consistent amount of current from just your solar panel and nothing else. Its much safer and more reliable to send the DC power to a battery for storing and then use the battery to charge your device.
You can also use a charge controller to regulate current and a power inverter to convert DC to AC for your home system. But in a real emergency, and with enough sunlight, panels, and time, you can get power directly from the sun using portable solar battery chargers.
How Do I Compare Solar Battery Chargers?
When you start researching solar battery chargers, it can quickly get overwhelming. To help reduce the overwhelm, think about what type of conditions you will be in when you need your solar power charger.
When you compare chargers, look at watts, volts, and price as well as features like protection from the elements, shock proofing, and durability.
Power
One of the main factors you want to consider when comparing solar battery chargers is power. You can find portable solar chargers which range in power all the way up to 18 volts.
For something like a cell phone, you can use a lower powered solar charger to lessen the risk of overcharging your device. The amount of power you need and how often you need it will help you to determine which solar charger will work best for your needs. A full-size car battery is 50-amp hours, it needs more power than your cell phone.
Inventory your electronic devices and other powered items first so that you know exactly how much power youll need to recharge them. Most solar chargers will not provide as much power as advertised so make sure you test it before you need to rely on it to save your life.
As mentioned above, using an internal or external battery bank to store power that is collected will make your solar power charger more reliable.
Current Regulation to Prevent Over/Under Charging
Most solar power chargers also come with a sensor or regulator which detects your device automatically and adjusts the current to maximize charging speed and prevent over or undercharging.
This type of technology is usually indicated by a proprietary Smart chip and reduces the risk that your device will be subjected to spikes or drops in current.
Energy Efficiency
An efficiency rating of at least 20% or above on your solar panel means it is more reliable in providing power even in cloudy weather or in wintery conditions. But the other components, including wiring, battery, and inverter can reduce the actual efficiency of your solar panel.
A high efficiency rated solar panel is critical because it means it is good at quickly harnessing energy from the sun. If the solar panel is not energy efficient, it negatively impacts your entire solar charging system.

All in One Solar Power Chargers
Many portable solar power chargers will slowly charge your devices using the power of the sun only when in direct sunlight. When the sun goes down or clouds roll in, you may not be able to charge your phone at all.
But all in one solar battery chargers have their own internal battery which stores the power collected when the sun is out so that your phone will keep charging or can be charged later, after the sun goes down.
