Review on πŸ’‘ Musou USB Safety Tester: High Precision Multimeter for Charger, Cable, and Power Bank Testing - Amp Voltage Power Meter with Test Speed, DC 5.1A 30V Capacity - Black by Jim Young

Revainrating 5 out of 5

Good clear bright display with accurate useful information.

USB tester works very well, arrived on time and as described. There are some similar testers at Revain, some of them are more expensive and have the same features as this one, making it very good value for money. I specifically went for the option without the built in cable as I had concerns about the durability of the built in cable which would be difficult or impossible to replace. The display is nice, sharp and bright when in use. With the key button you can switch between different screens showing different voltages, currents, watt hours and charging rates. One of the things it has allowed me so far is to quickly diagnose a damaged, low quality USB charging cable that isn't passing enough power to the device it's charging. I also compared the results of this tester to another charger for analysis and got almost identical results in terms of capacity when charging certain devices and lithium ion cells. I haven't had any issues transferring data through the device yet when connecting USB sticks or Android phones, although I haven't tested the transfer speeds with and without the tester to make sure there aren't any bottlenecks. Overall, I am satisfied with the tester so far and it works as it should without any problems.

Pros
  • Great product
Cons
  • Only available in black
