Very happy with the purchase Now I know if you’re loading the mobile or tablet After placing it delicately so that this one has connection. I also know the loading AMP and the tempeature of the circuit. Very interesting fact. Which brings more knowledge of what happens during the loading of such equipment or chargers that are suspiciously damaged. I can also know the discharge status of batteries and power banks with USB connection to download. Recommended A greeting And luck to all

A wonderful tester, you can set the limit on the upper and lower voltage, if the voltage goes beyond the set range, the tester will issue sound signals and disable the device connected to it, you can also set the current threshold (a). Measures capacity, current, voltage, resistance.

The order to Kiev was a month and 2 days later the order would be closed. The store not only does not respond but also does not read messages. The bomb tester itself took Bluetooth version. when connecting to the program on the phone should be enabled geolocation (finding devices nearby) if it is not enabled never the tester connect to the program link to the phone unnecessary, although with Samsung Galaxy Note 4 and so connected. through the program you can create a log file XLS with second-rate measurement of voltage, current and power consumption that was in real time so that it was clearer to make a screenshot as Looks.

It took 24 days to get to Spain. The package was a simple padded card, without further protection. The article was inside a transparent envelope. It was received without damage. The article syncs well with mobile, although the data refresh rate is only 1 update/second. The screen is small, but good quality. Good item for your price.

Very quick delivery to Germany within 15 days. There is no user manual. Using without App is easy. Using within the App is a bit tricky. Bluetooth pairing via android settings fails. Only bluetooth pairing via the App worked. Functions are not fully tested by me yet.

All right. It works smoothly. It’s kind of flimsy the meter, and with the P is or the cable, it folds easily. Even with some accidental little blow, it’s very easy for the USB A to be Rome. for safety, this meter should only be used supported on a table; which is difficult. Tip: Make meter stronger, and reinforced, so that it holds the weight and torsion better.

USB meter looks good. Display is easy to read. But the App for Bluetooth use is not fully translated into English, I saw some messages in Chinese. I also bought the input and output cables. These feel strudy to perhaps a little too stiff.
