Cant see Iphone charging symbol, this fixes that. Also you can see if your phone is getting charged in the first place also you can tell if it's nearing fully charged, from 5' away

I ordered two packages of 2. So, four all altogether. These were to replace older units. After getting lost in the mail for a few days they work well, and test accurate. These will be suitable replacements and a handy tool for understanding if your device is charging and by how much.

Works fine but I guess values on Ampers are different then actual values.

2 ports are nice. My phone quit charging through this, so i bought 2 new cables to charge my phone thinking that was the problem-that wasn't the problem, it was this device. Had i taken it out of the circuit, my phone would have charged, so the $ spent on new cables was wasted.

Gee, I already have a good idea about the voltage (5 volts) on a usb line. Both of the units I received always read 0.00 on the current no matter what I plugged into them. Kinda useless.
