I had been using multiple combinations of USB chargers and voltage/current meters before getting this. This is a great solution for combining both things. You get 5 ports and a very reliable source of power. A few nitpicky issues hold it back from getting a perfect score. First, it's easy to accidentally turn off the display. The sensor for doing this is near the front of the device and your hand naturally hovers over that area when using it. Moving the sensor somewhere less prone to touch would help this. Secondly, I wish the current display showed hundredths of amp. There are a lot of slower charging devices that won't register a tenth of a current and there is no indication it's charging. This would definitely cramp the display but would make the device even more useful. Those issues aside this is still an amazing device and I'm glad I purchased it. The USB PD and 20V USB C line have already come in very handy to test multiple devices. This is a wonderful all-in-one solution from a trusted brand.
