> 3 dayThe only reason I bought this product is for fast high capacity charging. It charges no faster than any 5 dollar gas station charger you would buy at the register. I installed an app to measure the charging rate, and in fact it is no faster that an el cheapo charger.

Greater than one weekI was having a failing Alternator on my car and needed an easy-to-use volt meter so I tried this. It is great in all respects.

> 3 dayUSB plug met my expectation. Works fine on charging my phone and the voltage readout is handy to keep track of my car battery voltage. I would recommend this item.

> 3 dayAwesome usb car charger, but Im giving it 4 stars as the voltage is 0.1 too low (I measured with two voltage meters). I wish its voltage was more accurate.

> 3 dayI have another one that is big and bulky. But the voltage display there and on this one are identical. So i guess it must be showing it right. Additionally, this one is small and convenient, with 2 USB ports. So I keep using this instead. Although the display is small, it is bright and easy to read. Worth it if I can predict battery failure by watching when the steady state voltage drops below 14 volts. At least I will know if the battery has failed. Maybe they should make the display blink below 14 volts.
