SinLoon 30cm Double Mirco USB Charge Y Splitter Cable, Micro USB 5P Female jack to 2 Micro 5pin male Y Splitter Charge cable for phones(MIRCO F-2MIRC M)

Was going to run a second cable to the outside blink camera but decided to try this instead. Worked great. This was used to power back to back Blink outdoor cameras. These were the XT and XT2 model cameras.

I have a PS4 controller with a keyboard that plugs into the controller. The keyboard doubles as an external battery so you don't have to worry about charging when the controller battery is dying. The problem I found with that is the inability to charge the keyboard AND the controller at the same time. You HAVE to choose which one you want to charge first. This is bad if you're playing for so long that BOTH devices are dying lol. This cable is awesome because it fixes that problem. You just plug in your PS charging cord into the female end of THIS cable and then you can charge the keyboard AND controller together. I'm sure there're other useful applications that this would be awesome for but my PS4 controller and keyboard are the reason I got it in the first place. So far, I find that it works very well and does exactly what it's supposed to do.

I ran a more powerful power supply to make up for the split. This still would only power 1 camera at a time.

works great as a splitter off a solar panel to charge 2 small security cameras.

Had to return this item. Tried using it to power both an Amazon Echo Dot and a small speaker. Result was noise and static on the speaker even when Dot was silent. Went back to using two wall chargers and two power cords.

This product is just as described and the only issue I have is that if I have two items plugged in at the same time one cable either doesn't charge at all or charges really slowly.

Works great for powering a raspberry pi 7" display along with a raspberry pi 3 from a 2.5A USB source with no undervolting - did exactly what I wanted it to do, on a setup that can be really finicky about power.

Worked great to power my Raspberry Pi 3 and official LCD display from a single power supply. No more lightning bolt icons for low power from trying to share power over the interface pins.
