This Voltage Tester, Current, Cargo and USB Data Transmission with LCD display (LCD Display USB Power Charger Data Transmit Current Voltage Tester + Capacity Tester – White) was acquired in DX – DealExtreme. A purchase has been reported in a previous article. This equipment is used to measure the tension in USB ports, the current used for USB devices, among other features.
The Voltage Tester, Current, Cargo and USB Data Transmission with LCD display has a cable with USB plug male, jacks and USB and mini USB female. The model is KCX-017. Seria EPZ a Marca? It accepts input voltages / output 3V to 7V with 50mA current to 3500mA. O load meter vai 0 a 19999mAh.
I thought fouls an instruction manual. Measuring the voltage and current is relatively straightforward, simply connect the USB cable at the exit PC USB, charger, etc. and connect the equipment's USB port Testator. I was in doubt as to the mini USB port, I do not know if it is an input or an output. I tested as input by connecting a Car Charger it and the phone in USB jack and it worked, then I suppose it is an entry.
I no load test, measuring the voltage only. Then I tried an iPod, at pendrive, at External HD, and a cell. As expected, the measured voltage was low in the first two (iPod was fully loaded), and highest in the last two. The USB ports on my motherboard can theoretically offer more than the standard 500mA, but still need to check exactly how this works. In tests passed anything of 500mA. Also tested the voltage of the USB ports NS-K330, that dug 5,00V, and also the output voltage of a battery with solar charger.
Quanto in carga, I was in doubt of how to measure. Apparently the Testator do is go telling how much charge passed him. Thus giving to place a fully discharged cell and check the end of the load which is the battery capacity. I do not know if the Testator It is already taking into account the energy lost due to the power factor. If not you need to multiply the value obtained for her. It is also possible to measure the load of a power bank, as battery with solar charger, for example. In this case the idea is to let the bank fully charged, connect the tester on it and then load multiple devices to exhaust the load, and then check for the actual capacity of the power bank. As only just started to be deducted and the load function seems to work, I have not done tests.
Por fim, the single button function Testator e do número de 0 a 9 that appears in the lower right corner of the display were also two unknowns that I'm still trying to solve. But apparently are 10 memory locations (load, apparently) that can be selected and set to zero with the button.
I can conclude that the Voltage Tester, Current, Cargo and USB Data Transmission with LCD display It is a device that can be useful in various tasks: find out if a phone cord or external hard drive is good, check that the voltage / current offered by a charger is correct, check the battery of an energy bank or a device is in good condition, among many other. For the price of only $ 6,44 is a great acquisition. The lack of manual hurt a little at first, but now I'm starting to dominate the device functions.
