Reviews
I love these things
It's hard to find out if the charger is bad or cable, this puts an end to guessing.
Useful Electronic Tool
It works perfectly, enable the maximum coupling from a wireless charger to my phone without a load the USB measures a precise 5V.
Perfect affordable Troubleshooting Tool
This is a great tool to use for troubleshooting. I've used it to test powerbanks for capacity (mAH), test the charging speed of devices with different cables (Amps), and test the output of usb power supplies (Voltage) / Amps) It's as small as a USB Memory stick and just as affordable. There's no reason not to have one.
Excellent
Works great when checking for voltage on USB adapter
Five Stars
Great little device which does as it says, very happy for the price
Great meter
I've had this meter for less than 3 days and it has already helped me figure out why my phone battery dies so quickly. This little device helped me figure out that the battery is only holding 2/3 the capacity it should be. Very happy that such an inexpensive device saved me from buying a new phone.
Great product
Very useful and helpful product. Easy to read display. I like everything about this little thing... especially the price. Lol
The product collects the data accurately.
It can be used to calculate the capacity of your phone or portable charger. Comes in handy all the time!
Just perfect
I absolutely love this device and will replace it if it ever dies. Very neat device for amp consumption...
Good for testing chargers and measuring power consumption
This item works great. I plan on using it to measure current draw of my Arduino projects.
