There are a few tricks to charging your smartphone with a solar charger

[P30]

It's finally September. However, since the end of the long rainy season and the beginning of August, the heat has been intense every day. To be honest, I spend a lot of time at home because of the Korona-ka, so when I go out, the moment I get out of the house, the strong sunlight and heat make me sick.

However, that is where I want to change my thinking positively. On the contrary, can we make use of this intense heat for something? When I thought about it, I thought that it would be possible to charge the "HUAWEI P30" using a solar panel, so I decided to put it into practice.

RAVPower's solar charger.When folded, it's a little smaller than the B5 size.

Perhaps because of the recent popularity of the outdoors, solar chargers that can charge smartphones and other devices have become relatively easy to obtain. I chose RAVPower's solar charger from them, and the price is less than 6000 yen.

This solar charger is equipped with three solar panels, but the point is that it can be folded and is relatively compact, so it is easy to carry. Since it is equipped with two USB terminals and supports a total output of 16W, it seems that two devices can be charged at the same time.

It's very easy to use, just connect the cable to the USB port, connect the device you want to charge, and place it in a sunny place. As a matter of course, it will not generate electricity unless it is exposed to sufficient sunlight, so for the time being, I installed a solar charger on the outdoor unit of the air conditioner on the balcony on the south side, which will be the most exposed to sunlight in the house. I connected the "HUAWEI P30", which has a considerably low battery level of about 30%, and left it as it was.

Then, a few hours later, when I checked how much it was charged, it was hardly charged. Why isn't it charged even though it was fine on this day? I tried various things, but it seems that charging may stop when the output drops due to clouds or shadows. Certainly, when I went to check it, a part of the panel was shaded, which may be the reason why it didn't work.

So I decided to revenge the next day. Based on the reflection of the previous day, how can I install the solar charger in a place that is not in the shadow and is always exposed to sunlight? So I decided to put the tripod that I no longer use on the balcony and forcibly hang the solar charger there to charge it.

This time I tried hanging a solar charger on a tripod that I no longer use so that shadows do not appear on the panel

Then, will it charge well this time? Unlike the previous day, it was a cloudy sky on this day, but even so, I was able to charge the battery from about 30% to 100% in about 4 hours. Of course, it takes longer than quick charging, but it seems to be useful if it can be charged this much even in places where power is not available.

Check the charging status from the setting screen of HUAWEI P30.The red frame on the left is the charging status on the first day, the red frame on the right is the charging status on the second day, and you can see that the charging is smooth on the second day when the environment is prepared.

However, since nature is the other party, it is necessary to check the situation diligently and adjust the direction and position in some cases in order to achieve stable charging, and it is also necessary to be careful not to be blown off on windy days. There will be. It seems that it is not easy to fully charge the smartphone if the solar charger is left outdoors, so I would like to think about how to use it effectively for a while.

When charging with the solar charger, never leave your smartphone in direct sunlight. I also inadvertently left the HUAWEI P30 outside for a while this time, but fortunately it didn't break down, but it became so hot that I couldn't hold the main unit ...
