5 cm Desk Power Grommet with USB-C, Built-in USB Port Desk Input, Power Grommet Outlet for Office Desk PC Desk Cable, 2" Mounting Hole Power Socket with Flat Plug, 1.8 m Cable

Perfect

Works great, easy to install.

My basic test results: I purchased 2 of these in October 2023 to replace broken ones from my recliners. These have the same diameter and that made the replacement very quick and easy. Using a cheap Android phone to determine fast charging: 5 volts = no (even when trying a 5V/10A adapter) 9 volts = yes 12 volts = assumed yes Since the information on the item page clearly states that the USB-A port only provides 5 volts , it caught me by surprise that my phone would indicate fast charging from both of the USB ports on the grommet. I stripped a USB-A to USB-C cable and connected a multi meter to the 2 wires that provides the charging power. I plugged 1 end of the charging cable to my phone and the other end to the USB-A port on the grommet and the multi meter reads 5 volts but just 1-2 seconds later, the multi meter reading goes up to 9 volts. The same thing happens when I plugged the charging cable between the USB-C port and my phone. Since the grommet can only serve 1 of the USB ports at a time, I assume it is the same circuit that provides the power to both of the ports. I also assume that both of the USB ports on the grommet can provide 12 volt charging voltage but due to limitations of my phone, my phone never received 12 volts from any port on the grommet. *Also something worth mentioning is that you should only plug 1 charging cable to the grommet at a time. If you are leaving an unused charging cable plugged into the USB-C port while using a charging cable plugged into the USB-A port, you might experience the USB-A port strictly providing 5 volts (no fast charging). Both grommets are in almost daily use by phones and tablets.

Update: The seller was quick to respond to my request for a replacement and sent one out right away. Luckily the new unit doesn't have the same issue so I'm changing my rating to 4 stars (not 5 due to worry the USB-A will still fail eventually). Bought this to put into an office desk I built. Main purpose was to use the USB-A plug to charge my ipad while it plays videos throughout the day. USB-C for charging phone as needed, and the AC outlet for anything else. Sadly the USB-A port seems to be faulty and it only charges for about 1 minute before it just gives up. It acts as if there's nothing plugged into it at all. I've tested multiple cables so it's the port for sure on the power grommet. Reached out to seller in an attempt to get a replacement sent out, will update review based on seller's support. Otherwise this device seems to be solid. The USB-C port charges quickly and the overall build seems very nice. I think I just got a bad unit.

Great item, install with a hole saw, adds charging to discrete locations….my 2 are on the apron board of our dining room table
