rather accurate I could not activate QC at 20V could only do 9V and 12V whenever I used a 30V power supply don't know why, product came with dead pixels you can see on the 12V value this is why I give only 3 stars to quality but I like this product and will buy another one.
great little USB charger with LCD display has 3 USB ports @ 5.1V and 1 port for QC 5.3V/9V/20V
Small but efficient USB charger. It has a wide range of input voltages so that it can be fed with many feeders that we have available with the only condition of equipping a connector of the type DC 5.5*2.1 mm, which is one of the most used. It has the great advantage over other chargers that it has a small LCD screen that presents a lot of useful information. For all outputs individually indicates the voltage and intensity. It also tells us the input voltage and the overall power consumed. Very good product. The delivery time has been very short since the order. Highly recommended salesman.
100% good
Great little charger.
First unit did not work and had a short circuit on the input. Other unit worked well and the device is very good. It is well priced so just a bit of bad luck that one was faulty.
Dead on arrival. Here is a movie as well: https://www.youtube.com/watch?v=nGH_kb9H7k4
