Solar Power Bank

We have already written about thin-film solar cells (opens in a new window) based on amorphous silicon. The article will focus on one of the most popular ways to use these devices – a power bank with a solar battery. The very idea of ​​storing electricity for future use for wearable devices (phone, tablet, flashlight, etc.) is very good, and if this electricity is also free (from the sun), it is simply brilliant. Is everything so simple?

Let’s figure it out.

I wonder why not a million?

Debunking myths.

Judging from the screaming names like Power Bank 50000 mAh solar, this is such a portable battery that will charge an iPhone 25 times, while it is enough to put it in the sun and it is ready to work again!

This article is not intended to be an overview of a specific https://de.the-celebrities.site/page-liebe-ist-immer-noch-blind-und-lauren-und-cameron-haben-keine-angst-vor-tough-co device. Let’s just try to explain how they are trying to deceive us with promises of what is currently unattainable.

Device weight.

It’s good to have a light and small power source in your pocket. Sellers also know about this, so they promise 200 grams of weight and a capacity of 20-30 thousand mAh (milliampere hours). If you see such numbers, most likely you are being deceived. The weight of one branded (and therefore not the worst) battery is 30 grams, its capacity is 2000 mAh, therefore, to achieve a capacity of 20 thousand mAh, 20,000 / 2000 = 10 pieces or 300 grams are needed.

Keep in mind that this is the mass of only storage elements, to which you need to add the weight of the case, microcircuit and additional parts inside. Therefore, a 20,000 mAh Power Bank should weigh about 500 grams. And 50,000 mAh is more than a kilogram.

We don’t think this is the best option to carry with you.

Charging from the sun.

Manufacturers of Power Bank with a built-in solar battery are in no hurry to indicate neither the characteristics of the battery itself, nor, moreover, its charging time. Let’s count.

Important. The real power of the solar panel is only enough to power the LED indicator of the charge from the solar battery 🙂

Why is this made.

Unscrupulous manufacturers are trying by all means to foist their goods in the hope of the lack of education of the consumer. The use of solar panels in Power Banks is a marketing ploy that increases the cost of the device and its attractiveness to a potential client.

Bright body solar charging = buy!
