Bought one of these to use while traveling. It works well as an extension cord, but don’t expect much out of its USB-A ports. I think calling them 5W ports is generous. They were able to trickle charge wireless headphones and earbuds but the charge rate was abysmal for phones and tablets.
For the important devices I ended up using my usual chargers plugged into the AC outlets on this cube. For that purpose, it was convenient and worked well, but I was hoping that I could at least charge two phones simultaneously from the USB-A ports and that was not happening.
The wireless charging pad on top also worked okay. The rate was slower than my other 15W wireless chargers, I’d guess that it’s probably aiming for 10W and getting 8W. Good enough for wireless charging of Samsung Buds Pro 2s or Airpod Pros.
Cord is 10ft which was convenient when locating the device on tables/counters in the various places it was set up.
