A backpack with a solar battery is an indispensable invention for travel lovers. A roomy backpack is usually made from durable, waterproof materials, and a portable power source will allow you to charge your favorite gadget, even when you are far from civilization. Ideal for hiking, mountain hiking, cycling and other exciting outdoor adventures.
What to look for when buying
When choosing a backpack with a solar battery, you should pay attention to several important points. The smartphone consumes approximately 10W when charging via USB. However, the power of the panels indicated by the manufacturer is valid only for sunlight directed at a right angle and not obscured by clouds or other obstacles. This means that a solar panel with a declared power of 10 W in reality produces much lessamount of energy, so it is worth buying a device with a power reserve of 2-3 times: this is necessary for comfortable work. Purchasing a backpack with less than 10W of solar power makes sense if you are going to charge something small, like a digital watch.
There are solar panels with and without a built-in battery. In the first case, the panel first charges the battery, to which you can then connect any gadget. Pay attention to the size of the solar panel: the smaller it is, the longer it will take to charge the battery. Batteries without a battery function only on a sunny day and transfer energy directly to the gadget. It is not possible to accumulate a charge and use it later in this case.
It should also be noted that a lithium battery increases the cost of the device and reduces its service life to a couple of years. At the same time, the solar battery itself works much longer.
