- This USB Charging Current / Voltage Detector Mobile Power Tester - Ocean Blue 3 is very good. works really fine. I can measure in what voltage my device is charging and on what current. This gadget is very useful to check your power supplies or cables. Really satisfied and recommend to others.
Description
Material: plastic
Working range: voltage 3.5V - 7.0V; current 0A - 3A
Resolution: voltage 10mV current 1mA
Error: voltage < ± 1 percent current < ± 2 percent
Full-scale voltage drop: 200mV ( when measuring current )
Working temperature: 0 - 60 Deg.C
Use:
Very simple and practical small instrument:
◆Small and portable, no need for external power supply and other ancillary equipment, plug and play
◆It can detect any USB output power, charger, computer USB, car charger and mobile power
It can easily measure the no-load voltage of the USB port, the load voltage and the current when the device works, and judge the charging
Whether the performance of the device and the charging cable meets the requirements
◆Simple operation and wide application range: USB voltage and current are alternately displayed, and the test results are clear and clear, which are suitable for factories, laboratories and ordinary users

- good and cheap little helper to indicate voltage and amperage. it shows each for a second and then switches to the other. so real time amperage observation is a challenge, but it was expected for the price. see my video for a closer look at the product in action.

- výborná vec pre potreby domácnosti. ukazuje celkom presne V aj A. Ja ju používam aby som zistil či nejaký spotrebič nabíja a kedy končí nabíjanie - ampére klasnú na nulu. z výrobkom som veľmi spokojný - používam ho už asi 4 rokygreat thing for household needs. shows quite accurately both V and A. I use it to find out if an appliance is charging and when charging ends - amperes classic to zero. I am very satisfied with the product - I have been using it for about 4 years

- Legge amperaggio e voltaggio. Ci si rende conto di quello che arriva realmente nei nostri dispositivi usb quando li carichiamo o li infiliamo in una qualsivoglia presa.

- A very useful tool, which can show how much current a USB port is delivering (and the voltage). Some phones and tablets can use 2A or more, and it's good to be able to check this. Easy to use and also great value.

- A great little tool for iPhone diagnostics. Use it to get an idea about the motherboard/charging status with all the shattered iPhones.

- A simple usb voltage gauge. It does its job to test and see if cables/ chargers/ external battery packs are QC compliant.
