ANRANK USB 3.0 Female to Dual USB Male Extra Power Data Extension Cord Adapter Splitter Y-Cable Black

Wireless CarPlay wasn’t reliable on my iPhone 17, so I had to go back to wired. The included USB port doesn’t even give enough juice, so this cable does the trick - plug usb into cig lighter to get power, and other to USB input. Just make sure your last usb cable to your device delivers data as well as power - many don’t! 🤷‍♂️🤦‍♂️

To make a long story short, some vehicles (looking at you Nissan Murano) with wired CarPlay don't produce enough juice at the main USB port to reliably power a wireless CarPlay adapter. This cable allows you to pull in extra power from a USB charger (presumably one of the ones in the cigarette lighter port), which then provides enough juice to power the wireless CarPlay adapter.

Adds power to active USB extensions. I am using USB 2.0 Active extension 32' and that requires power. Regular Mac or PC ports do not provide sufficient power. So I use this to add 2.0A power to the cord, and it works great.

Works great, if you know what it's for. I needed some of these to power my usb drives attached to my pi because the pi basically doesn't supply power through the USB ports, so you have to power things separately. If you don't use something like this, the drive may appear to work at first but as soon as it needs more juice it glitches and you lose data.

And my incredibly well-thought out plan was a bust. My battery still can't push enough to not 'slow-charge' BUT thats not likely a fault of this adapter as the slow-charge WAS faster with this in use, if only marginally so. Built well, a bit chonky, but everything fits snugly and should work totally fine. Cant 100% confirm it's charging power but I'm not disappointed with what I got.

My Virpil joysticks eat a lot of power from the USB bus, so I had to split the power sources to keep everything else from draining. This adapter allows you to use an extra USB port for power. You can also use a phone charger, and plug in a USB extension cable to get power. USB 2.0 will suffice for that purpose - just keep in mind that a powered bus doesn't turn the lights off on your devices. It just cuts the connection to the PC when it turns off. For joystick purposes, that would be useful so you don't have to keep recalibrating it. one would think digital connectivity would have solved the calibration issues by now.

Purchased to inject power to usb connection from Android head unit so I can utilize wired Android Auto and fast Charge simultaneously. Unfortunately this capable of cannot be used for this purpose. The charge only side does not pass data or power. This review includes a screenshot of the message I get when trying to utilize the power only side without the other side connected at all. When I connect the Android auto to the data plus charging side everything works okay but I do not get any additional current as the time remaining to full charge does not change at all whether the charge only side is connected or not. Absolutely useless!

Used splitter to provide additional power from Raspberry Pi 4B to SAMSUNG T7 Shield 2TB. The data transfer speed remains the same (~1.8Gb/s) before & after connecting this cable in between.
