A small portable solar panel as a power source for your devices
Until recently, solar energy was obtained through huge panels that were placed on the roofs of houses and industrial buildings. Over time, technology advanced and the production of smaller solar chargers began. Now you can take solar energy with you. There are many options for affordable portable solar chargers. Those smaller panels were used to produce electricity for street lighting, traffic lights, lamps in households, and smaller household appliances. Today, you can take a solar charger with you. They will supply your devices with a sufficient amount of electricity. They are your only safe source of electricity in case of need for survival in nature.
In case of emergency, or during a long stay in nature, you must be prepared. Being prepared for emergencies means being able to generate electricity off the grid. In such cases, you need portable solar charger to charge your portable batteries and USB devices. You need to provide yourself with off-grid electricity production. In such cases, solar charger are the only solution to charge your lamps, telephones, USB devices, and portable batteries.
There are a variety of portable solar chargers on the market. All of them are compatible with rechargeable batteries (Li-Ion pack or AA battery charger) and many of them come with a built-in battery. You can even use solar energy for cooking.
All you need is the Sun
Portable solar chargers work by placing them in the Sun and plugging your gear into them. They function in the same way as large industrial solar panels. You need to put them in the sun and plug your device into them. The speed at which solar panel charges depends on the angle between the panel and the sun. It is best if it is at an angle of 90 degrees to the sun.
ATTENTION: Be careful about overheating. Avoid charging devices directly from the solar panel in the hottest part of the day. Instead, charge the battery first and then charge the device. Heat reduces the performance of the panel. Also, you must keep your panel away from hot rocks, stones, or metal.

Ryno Tuff Portable Solar Charger – 21W
ADVANTAGES – GOOD SIDES
This is perhaps the best portable solar panel. The product has passed a whole series of official tests like load test, output power test, and efficiency test. It maintained 10w on one USB port. It uses SUNPOWER solar panel cells, which convert 21 W of solar energy into electricity. Conversion is done at a rate of 22%-25%. One of its advantages is the price. It can often be found up to 15% cheaper compared to the same products from other manufacturers. Any USB device can be charged through it (phone, tablet, fan, GPS device, headlights,…)
Pairing the solar charger with a separate external USB battery is recommended. That way, you wouldn’t have to destroy the built-in batteries of your devices. This will prevent your device from heating up in the sun during the charging cycle
It is very easy to use. Just unfold the solar panels and place them in a place exposed to direct and strong sunlight. If the indicator on the USB output port glows red, there is enough sunlight to charge the device. The panels must be turned vertically towards the sunlight in order to obtain maximum solar energy.
This solar charger only charges your device when exposed to sunlight. It only takes pure solar energy and converts it into electricity. The panel can be damaged if it is exposed to direct rain. In the middle of the day, when the sun is at its strongest, the panel may overheat and stop charging.
Its price is up to 15% lower compared to the same products from other manufacturers

Efficiency and reliability are key factors for purchasing this panel. BigBlue 28V converts approximately 24% of solar energy into electricity. That is why it is one of the most efficient models. It has a simple and durable design. It is possible to charge it even in conditions of partial flooding because it has an automatic restart function. Its big advantage is its price. It is one of the cheapest panels of its size with almost 30V capacity. It’s simple AND that makes it cheap to produce.

It consists of three mono-crystalline panels that allow it to convert with a high efficiency of 25%. The device has automatic current and voltage adjustments. This allows the device to deliver three amps per port under direct sunlight. With its 20 V, it provides solid high-speed charging at a reasonable price. With two USB ports, the X-Dragon puts out at least 2.1 amps through each port.
The panel comes with numerous loops and carabiners. This makes it easy to hang it on a backpack, tree, or tent. It allows the board to be tilted more directly toward the sun. It performed well when the sun is not shining overhead, then its charge is 624 mAh. During direct exposure to the sun, its charge is 1220 mAh. Its exterior is made of quality material. When closed, the solar panels are well protected from scratches and damage.
It has a mesh pocket with a zipper on the backside. It protects the output ports of the charger and can easily store an extra battery. Also, the pocket can be a great place to store your cell phone so it doesn’t get too hot while the solar panel charges it.
The X-Dragon does not have an outlet for charging larger devices such as a laptop and does not have a 12-V connection. The solar panel could be a little more portable and lighter.
Excellent ability to catch the sun. It provides good charging even when it is cloudy.

Before you buy a panel, think about your needs. Finding the right solar charger depends on various factors. For example, the number of people that are going into the wild with, and for how long; what kind of devices do you need to charge; are in a low-light zone or a sunny area…
The bigger the charger, the more solar panel surface area that can pump out power. Anything less than 15W could get you in trouble. Smaller panels have more trouble charging, especially in bad weather. If you want a reliable solar charger in different weather conditions, look for an option with large panels.
A small solar charger can charge your mobile phone 5 to 10 times. They have often integrated units. So, if something goes wrong with the battery pack, your charger could be rendered useless.
