USB testers have gone far past simply testing the output voltages and energy of ports, and may now take a look at and examine for counterfeit Apple chargers and cables.

- Backup energy: Supercapacitor
The Energy-Z KM003C contains a 1.54-inch 240 by 240-pixel IPS colour show, and may perform a spread of checks, together with voltage/present detection, capability/vitality take a look at, USB-C E-marker identification, protocol take a look at, and extra.
Additionally: This $30 USB-C cable features a surprisingly superior function
All the pieces is managed utilizing 4 buttons, which is quite a bit simpler than among the different meters I’ve seen which have a bewildering array of rotating dials and tiny click on switches on them.

Additionally: The perfect moveable energy stations you should buy
The display can be huge, clear, and simple to learn. I can swap between quite a few colour schemes, and it rotates mechanically due to a built-in gravity sensor, permitting me to see the readout it doesn’t matter what the orientation.
Along with all the ability and protocol data that this meter can ship, two options that I actually like are its potential to detect real Apple chargers and browse the E-Mark chip in USB-C cables.
Constructed into the Energy-Z KM003C is a supercapacitor that acts like a short-term battery, permitting the unit to proceed to run for just a few seconds even when disconnected from energy — a helpful function!
At $110, the ChargerLab Energy-Z KM003C USB-C meter is not low cost. In truth, that is a premium value for a USB-C meter. Nonetheless, this can be a high quality, well-made, practical meter that I discover is a reduce above the remaining, and provides up options that you do not see on cheaper testers.
