I have a lot of auxiliary devices I use at work, and needed something that could handle the power load of a 13" iPad, iPhone, Apple Watch, Airpods Pro and a bluetooth headphone (not Apple). Using the three USB-C ports, with my iPad and headset plugged in directly, and a three-in-one stand for my phone, watch and earbuds, all devices charge up in excellent time, with the standard USB-A port to spare. If I have one critique, it's the location of the ports on the bottom of the adapter, which isn't optimal when paired with a desk-mounted power point. (Fortunately, I was able to find a way to detach the power point and flip it upside down--so far, building maintenance hasn't discovered my modifications.)
One caveat--I am using this with the British-style plug type, which provides a pretty sturdy physical connection to the power point. If you are using this adapter with the other plug types--Euro or US--I can't vouch for the security of attachment. My experience with similar adapters of this style and weight is that they tend to pull away from a vertically-mounted power point when fully loaded, and may require a bit of propping up to ensure a stable physical connection. That said, I haven't personally tried using this adapter in the US or Europe, so the design tolerances may very well provide a sufficient tight & secure connection--you'll have to see for yourself (or read other reviews). :) But it's a minor cavil--overall, I am very satisfied with the purchase.
