## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Works well  hard to read
  

*by M***C on Reviewed in the United States 🇺🇸 on June 27, 2022*

Found the display a little harder to read than other testers I have.  I ordered because it has a type C portcame without instructions which would help as it has a ma hour display, but not clear on how it works and how to reset.

### ⭐⭐⭐⭐⭐ 







  
  
    Woorks quite well
  

*by R***Y on Reviewed in the United States 🇺🇸 on May 31, 2022*

This device accurately measures the voltage and current consumption of the device connected to it. BE AWARE that the picture may be deceiving. Make sure the panel has a USB regulated output and not just the raw unregulated voltage that some panels provide. Obviously if the panel has a USB output then you're okay. If it is just a round coax connector then it may be putting out 12 volt or 17 volts unregulated and you will damage this device, as the specifications state the maximum voltage is 7 volts.

### ⭐⭐⭐⭐⭐

*by S***H on Reviewed in the United States 🇺🇸 on November 27, 2019*

This product does exactly what it claims with dead on accuracy very easy to use but I do recommend down loading the manual witch goes more into detail other than that I'm very happy with my purchase and will put it to good use. Recommend it to all.
