Modern USB gadgets have become indispensable helpers not only while traveling but also at home
First of all, of course, our traveling readers will stock up on high-capacity flash drives, which will be useful for storing many photo and video files that no longer fit in a camera or video camera. On the online store page, you can choose USB flash memory with a capacity of up to 256 GB. Such a memory capacity should be enough even for the longest trip.
For comfortable work at a desk during night or evening hours, USB lights, also operating directly from the USB interface, are perfect. Their main difference from LED flashlights powered by batteries is reliability and efficiency – you won't have to buy batteries that drain very quickly every time! It's better to buy a USB light on a flexible or rigid stand, place it near the screen or keyboard, and continue working.
In summer, for cooling the body, it's better to use USB fans that have proven themselves excellent. Of course, you can buy economical fans at any hardware store, but they are powered by 220 V AC and have excessive power. It's better to purchase compact, attractive, and simply reliable USB fans that can be placed in any convenient spot right on the desk. And a not-too-strong airflow will always be guaranteed, quite sufficient for comfortable work at the computer.
For winter, it's better to choose USB slippers. Of course, you can also assemble them yourself using nichrome wire of the required cross-section and a 12 W switching power supply. But the wire may overheat, and the aforementioned power supply will easily fail at the first voltage surge (recall cheap cell phone chargers).
It's better not to take risks and buy branded USB slipper models that can heat up to 45-50 degrees and work successfully under any changes in input voltage. They are equipped with convenient 1.5 m cords, the length of which is sufficient for comfortable work near a computer or laptop.
In winter, fingers in a cold room also risk getting cold. In the latter case, it is recommended to buy USB gloves made either from pure wool or from artificial wool substitutes. In any case, these types of gloves do not overheat, have a separate cord for each pair, and cost the minimum, so any user can afford to buy them.
