Review: Funciona correctamente pero no tiene el adaptador USB A a micro USB que muestra en las fotos del producto
Review: I've used this on multiple occasions to test / debug a slow charging USB port. It is easy to use for the most basic tasks, and fairly easy to figure out the more advanced functionality with a bit of messing around, but has a user guide if needed. It's bright enough to read, easy to carry around, connects and displays data quickly, and not too expensive for the peace of mind of knowing where the issue is. Definitely worth taking with you if you suspect you'll need to test a USB port.
