18 Aug The best solar chargers for mobile
Are you looking for a good portable solar charger for your mobile? This summer you will not want to go out without these solar external batteries to the field, camping or the beach. We present the best solar chargers for your smartphone or tablet, perfect for charging your devices when you have no connection to the power grid or do not want to take the typical battery that we usually use.
Obviously if you are in an apartment or in your house, this type of batteries that are charged by sunlight, maybe not very useful, but if you go on a trip and you are at a campsite or you go hiking for about How many days in the field, it is possible for a solar charger to become your best friend.
Keep in mind that these batteries will charge more or less quickly depending on the weather conditions and the orientation of the charger relative to the sun. If the day is very cloudy, the load will be very slow. In this case, it is better that they also have an energy storage function and that they also act as a traditional external battery.

What should we look for in a good solar charger for mobile?
We have to have a few things clear, the main thing is that you will have to make a sunny day for the battery to work properly (in the case of solar chargers that do not act as a battery). Also, you have to place the solar panels perpendicular to the sun’s rays to maximize the battery’s charge.
Size? Keep in mind that the solar panels must be large to capture the maximum possible light and then transform it into electricity that will charge the battery of our mobile. The bigger the better … but without weighing much …
Capacity? Between 10,000 and 20,000 mAh is fine, a capacity more than enough to use with our smartphones and tablets.
What will we be able to load? It depends on the connection available in the external solar battery. The usual thing is to have several USB connections.
Resistant to water? Well, if it’s raining, it’s possible that it does not get much sun, but it’s a good idea to have some kind of protection against humidity if we’re going to be outdoors all day.
The efficiency of the panels? Bad news in this section: almost all solar panels have a very low efficiency in the conversion of sunlight into electrical energy: it usually hovers between 23% and 24% in the best panels … and can go down a lot in the worst options ( up to less than 10%). Keep an eye on this. Do not keep anything below 20% in the case of solar chargers. If they also have a battery function, you can lower the scale to 10%.
eye! Many do not act as a battery: no energy is stored inside them, they simply transmit it to the connected device. This means that they can charge your phone while there is sunlight. There is some model that does have this function.
Output amperage? The more the better. It is usually around 2.4A, 2A in the best starts, and 1A in the worst. If you have several USB outputs much better.
Extras: Some have LED lights and even lighters.
