This adapter allows for an inexpensive and quick “make” from a familiar cable with a microUSB (2.0) connector a less common cable with a USB Type-C connector.
The adapter comes with a milk-white zip bag. [Irony] I think the kit is sufficient to start using the device “out of the box”
But before that - we will make a detailed inspection. MicroUSB (mother): the plastic rim is made a little untidy - there are nano traces of flashing, which in principle do not interfere with switching, but can undermine the mental health of perfectionists. As for the pairing of devices, the corresponding plug in this outlet holds very reliable and firmly.
Type-C (dad): the essence is the same - from the point of view of geometry and manufacturing no complaints. The only thing that is a little depressing is the presence of an aluminum shell. Not. Not even that. There are no questions to her - she looks cool, it’s nice to pick up one’s hands. It is annoying that the Chinese usually put it on “glass” glue, like a super-glue that crumbles and crumbles during vibrations and deformations. Although, if necessary, this can be easily corrected, having the right straightness of the hands and a couple of drops of solid glue.
To test electrical capabilitieswe’ll carry out an uncomplicated test: ceteris paribus (power supply, cable, load) we switch the load and the power supply first without an adapter, and then with it. The very dimension of the numbers will be of secondary importance in this experiment. Will we be more interested in? delta, i.e. a change in voltage and current.
When connecting the load in the “1A” mode,? V was +0.03 volts, and? A -0.02 amperes.
When connecting the load in the "2A" mode,? V was -0.03 volts, and? A = 0.
Of the measurements made, it eloquently becomesit is clear that the voltage and current losses when using this adapter are absent disproportionately small and are at the level of error of the “white doctor”. Of course, this is due to the quality of switching plugs in the connectors and the small length of the conductors. One way or another, I do not see any objective obstacles to using this adapter for its intended purpose.
+ price tag
+ quality of materials (aluminum)
+ plugs in connectors hold securely
+ very small voltage and current losses
± we expect a simple repair of the shell
- data exchange only at USB 2.0 speeds (microUSB 3.0 just does not fit physically)
- I would like a ring / cord / carabiner or some other hook for reliable anti-loss fastening
