    Must Have for road warriors
  

*by S***. on Reviewed in the United States on June 9, 2018*

Works when trying to get all the devices charging at night on the road. This is a must have for every road warrior that ever woke uo in the morning to a nearly dead phone or headset or some other device that got plugged in to a USB port that quit working when another device was plugged in to the next port.

### ⭐⭐⭐⭐⭐ 







  
  
    This USB Multimeter & Safety Tester is a "must have" for RV Inspectors like myself.
  

*by D***R on Reviewed in the United States on February 9, 2019*

I inspect and evaluate an RV’s features, technical systems, road worthiness and check for any life safety issues. This USB Multimeter & Safety Tester helps me check the voltage and mAh (Milliamp Hours) of each USB port in the newer RV's. It has a nice display of the testing results for my inspection report photos.

### ⭐⭐ 







  
  
    Reboots
  

*by D***W on Reviewed in the United States on April 21, 2019*

Tried to use it in several different batteries to see if the were charged or depleted, but it keeps resetting/rebooting every few seconds or every time it wiggles just a little.  Not sure why.
