As more and more ports are removed from our smart devices, it seems that we can choose one of two options for using peripherals: either buy a dongle to continue using wired devices, or switch to Bluetooth and deal with permanent maintenance of the battery.However, if none of these options work for you, there is a third option available [befinitiv] In this version showed us He integrated a miniature solar panel in the earbud box Allow them to charge automatically.
First, he first disassembled the earplug box. For those who have not tried these products, they can usually only be charged when they are in a suitcase. In his suitcase, the suitcase itself also contains a small battery. Soldering the wire directly to the battery can charge the battery without losing as much power as it is connected to the USB pins on the circuit board. Even so, the battery can only produce 1 volt, so he needs a 5V boost converter to charge the battery properly. However, this also brings its own problems because it cannot be put into the case correctly. To solve this problem, he desoldered all the components and assembled them together to install the converter in a smaller space without modifying the housing in any other way.
After completing all these tasks and connecting the small solar cell to the case, [befinitiv] There is a smart solution to fully charge his wireless earbuds without having to carry a cable or dongle every day. We have seen many interesting solutions to solve the problem of various electronics manufacturers removing the ubiquitous 3.5mm headphone jack, and not all manufacturers have dealt with this problem without some other quirks.
