Opening the receiver went smoothly. It sits securely on the table thanks to the rubber feet. Inside is a rather large board, a bunch of microcircuits and crumbling. Inside there is an inductor and a receiver board.

Studying and testing a Qi wireless charger (sudden end). (Part 2 "Utility for LG G4")

Opening the transmitter. But the main emphasis will be placed on testing the effectiveness of this technology and on trying to introduce the receiver into a smartphone. The base looks like a small rectangle with a rubber border on top (to hold the smartphone) and with transparent decorative "ears" on the sides, which are illuminated by blue LEDs. The presence of the cable pleased, they could not put it. The inclusion and verification of the entire structure took place in seconds.
Of course, due to the curved textured cover of the smartphone, such a sticker looks like a foreign body, but I expected this. The device is 100 mm long and 10 mm high. The LEDs illuminate the transparent plastic "ears" quite dimly. In this review, I will show my acquisitions in the form of a universal Qi wireless charging receiver and a corresponding transmitter. Came with the rest of the devices in one package.

The receiver board is connected to the micro USB connector with just two wires. This means that for DATA versatility, the pins are shorted on the connector itself. But in the evening you can notice a smooth flicker during operation. The controller on the board is designated as BQ51020, which can output 4-10V at a current of no more than 1.0A. The base came in a transparent blister. We connect, we fix, we check. The second purchase was a universal sticker to add wireless charging technology to most devices with USB or Lightning ports.
Shop I did not set out to study it, but at least I’ll post a photo. The board is universal, suitable for turning USB 180 degrees, and for connecting devices from Apple. The sticker is sold in a small https://jiji.ng/cars/cadillac-escalade-2013 cardboard box. Inside, I found the device itself, a meter cable and instructions. Everything is held on by glue, but if you are not zealous, then nothing will come off. It looks quite thin https://tonaton.ng/s_35-dog-collars, the insides are sealed in a hard plastic bag, from which only a thin wire with a micro USB connector sticks out. $8.95 Along with the case-book, a base-transmitter and a universal receiver came in the form of a sticker on the smartphone case. ________________________________________________________________________________
