Atorch USB voltmeter ammeter from AliExpress

Aliexpress store - https://letyshops.com/r/aliexpress-1j... Unboxing, review, and testing of a cheap USB ammeter. HD display 8192 pixels; some copper alloy (manganin) is used, which has almost zero resistance and supposedly doesn't affect the charging speed of devices. In fact, all smartphones have native chargers that support fast charging, but as you can see in the video, they took 4-6 hours to charge... Moreover, in the photo on AliExpress, the coil looks golden, bright yellow. In the video, however, the color is clearly like old bronze (meaning I admit it's not the metal as stated). Without a tester, it takes 2-2.5 hours to charge. The additional charger for action cameras apparently doesn't charge any batteries correctly, charging too quickly and incompletely – it's better to charge them in the cameras themselves.
