First job: a KAMJOVE auto-fill kettle whose swivel is sluggish — swap the swivel motor, heating is fine, fifty yuan. Second job: an electric kettle not making contact, 1800W 8A, bought for two hundred-odd; today the five-to-six-hundred all-stainless ones are built like the two-to-three-hundred ones, imitating the American Westinghouse (Westinghouse six hundred to a thousand). Third job: a noodle press (a viewer found him on Douyin): won’t charge properly, red light keeps blinking, never got wet; the new multimeter (Fnirsi) has a nice clear display; on the DC volts range the battery is flat — should be 12V, only 3.5V, and it won’t charge (the 4.9V won’t rise); the battery leaked — the usual failing of these small cells, the cell gets burned through while soldering and the electrolyte leaks, the cells are scrap; internal resistance reads 20/17 (mΩ); re-cell (new cells spot-welded, no narration); OK, full charge; charging at 11W (caption says 1 W) 0.09A, 12V, no problem; ¥50 for the repair, the noodle press cost two hundred-odd. Comments: pure hobbyist; the coupler is ¥10; this guy is skilled and stocks every part; why bother fixing it for 50; same noodle press, same problem.
