Product looks like well made one. However, on the first use it charged the phone only up to 80%. On the second use the charger started to overheat and was really, the cable was hot, the usb outlet was hot. Checked usb outlet with other devices and it worked just fine. So I guess it might be a lottery with buying this device and I didn’t win.
The product is great overall. There is a problem with the built-in charging cable, it is very lose so won’t be able to just grab it with one finger, lost it’s meaning as designed.
