In summer, apart from a lot of sun, we also leave the house more, and that makes a perfect combination to need battery on long days at the beach and pool. In turn, if we buy a power bank that is charged through solar panels, we would have the perfect combination. Or so we think.
Today we are going to see if these types of devices are really worth it or, on the contrary, we have much cheaper and more interesting options.
solar external battery
We have all seen them at some time, and they have been able to attract our attention. However, if you are thinking of purchasing one, wait. They are not what you think and maybe all you get is throwing money away.
But to see how it really works, we are going to put a couple of examples that we can find on Amazon.
Its price is about €30, something standard within this type of device. It would have 20,000 mAh and its operation would be the same as any other powerbank with the difference that apart from being able to charge it by cable to the mains, we could also increase its battery with light alone, or so they say.
If we carry out a test we can see how in about 1 hour in full light on the beach the autonomy of the external battery goes from 25% to 28% (600 mAh). That is to say, we would have to throw in the 8 hours of the most sun on a clear day to be able to charge our mobile, which is more than likely not even fully charged.
In summary, as an emergency measure may be fine, since it would work for us to be able to charge our device, even if it is 5% if we stay somewhere on the planet, we do not know how to return and our phone has run out of battery. However, as charging station if we go to the beach or the pool and we want to recharge them while we bathe… It is not the solution. We will end up using it like any other, without taking advantage of the cost of having paid for a device with plates.
Besides, the heat and direct sun is not good for our battery. It is true that the part of the solar panel is prepared, but that does not mean that it does not affect the rest. It will always be at a very high temperature, which is not good for their conservation.
Our opinion? These types of gadgets are designed so that the user who buys them sees in them a utility that they really do not have but that once acquired, as it works well in the general appearance of any other powerbank, well, you keep it. However, for the same price you pay for one like this you can get a higher quality, better brand and larger size. Therefore, Don’t waste your money on these types of products. unless you need it for specific needs.
Here I leave you another equipment that for the same price has much better characteristics than the previous one. It is true that it does not have plates, but I assure you that you will never use them.
