HIGHROCK 30cm USB 2.0 a Power Enhancer Y 1 Female to 2 Male Data Charge Cable Extension Cord(1pc)

My issue I was trying to solve: I have a phone I was trying to charge and pull data from for hours. I noticed that my phone was losing charge instead of gaining or at least maintaining it. There seemed to not be enough juice coming from my router to handle it. I bought a 3.0 cable like this, and it did not solve the problem, it was being plugged into a 2.0 port, but that shouldn't have mattered. Even plugging in the extra "power only" side didn't resolve or even do anything as far as I could tell. So I thought maybe I should just find a 2.0 version. What this cable did for me: Using the same usb cable I was using the whole time to charge my phone, I plugged it into the "data and power" side of this adapter and the adapter into my router, I waited on plugging in the "power only" side in. I watched over a few hours and my phone was actually charging up and passing data. I have tested this for a good week and I have yet to have the need to plug in the "power only" side in. Something in this adapter is doing a better job at pulling power and data from my router. I'm very satisfied with this product. Should the cable not hold up I'll update this review.

Used to power my FireStick from two USB ports on the TV. Worked great! One USB isn’t enough power (FireStick shows error message) - but this worked to get enough power! UPDATE: Just realized that with my Panasonic TV, when turned off it cuts power to the FireStick. So when you turn the TV on the FireStick starts up and you have to wait. Not a huge deal, but wish those USB ports on the TV were always hot. Still better than having cables hanging in view.

2 quick points for those wondering about the use of this cable: 1) This cable has only 1 data-transfer connector. The 2nd USB connector is for additional power ONLY. This cable is NOT used to split a data signal between 2 devices. Its purpose is to provide added power to a USB powered device. 2) This cable is a USB 2.0 version, which is compatible with both USB 2.0 & 3.0 devices, but data-transfer rates will be limited to USB 2.0 speeds. If you want USB 3.0 speeds, you may need to spend a bit more for a similar cable with a BLUE data connector (instead of both USB port connectors being WHITE).

If you find this review helpful, please feel free to give it a quick 'Yes'. Thanks. My experience: I needed more power for a 1TB external hard-drive than 1 USB port would provide on my old Dell computer (drive would frequently disconnect when in use). The drive is USB 3.0 (powered through its USB connection) but my computer has only USB 2.0 ports, so went with the cheaper 2.0 cable version since my computer ports limit me to USB 2.0 data-transfer speeds either way. Ordered from the only domestic supplier I saw (SKY-LINE 'Best Seller') that didn't have the long international shipping wait time or the Amazon minimum order (or Prime) requirement for free shipping. For their $3 cable price (free standard shipping), they shipped in 1-2 business days and I received it via USPS in less than a week (sooner than expected). Arrived in a padded shipping envelope with the product packaged in a zip-lock type plastic bag. Product quality: I took a couple of minutes to test the cable connectors using a simple USB device with a power LED (I connected a flash drive). Sure enough connecting 1 of the USB port connectors to my computer worked as normal, but connecting only the other connector just powered the device without my computer 'seeing' it (provided power only, no data). This confirmed that the 2nd USB port connector is for added power only, as advertised. I gave each connector a few gentle wiggles while in the ports, with no connection issues noticed. The 2 port connectors were not labeled (Data or Power only), but my quick trial & error showed me which connector was for power only (not that this usually matters if both are connected anyway). I saw no other visible issues with this cable or its connectors. 12+ inches (30 cm) in length, with snug connectors and reasonably thick wires/insulation. The connectors do appear just a tad different from those pictured, but otherwise the photos are fairly identical to what I received. Connected my 1TB external hard-drive and it did the trick (no disconnects since). If your external device needs a bit more power than the single USB port provides, and are fine with a USB 2.0 version, this may be well worth the $3 price-tag.

We need an external hard drive for our Wii U... so we ordered one. When we tried to set it up the Wii said it was incompatible. My heart sank a little because my son wasn't able to play a new game he had earned and was patiently waiting for. Turned out the Wii U couldn't supply power and transfer/read files to the external hard drive through a single cord. We order this power supply cord and it has worked amazingly. Highly recommend it😊

I purchased this item to provide power to a hard drive being used by a gaming console. The cable did not work. I plugged the external hard drive directly into my computer and could read and write to it, but when I plugged it into this Y cable and then into the computer, it couldn't recognize the disk. I tried it on both USB plugs as well as powered and non-powered. It simply didn't work. I may have gotten a bad cable, but I got my money back and bought a powered hard drive instead. I wasn't hassled on the return. Overall, I can't recommend this product based on my experience with it. It doesn't work. 1/5 stars.

I was researching splitting the power side of the USB cable for my cars dash cam because the head unit can only provide power for up to one hour after shutting the ignition off - its maximum configurable time range to prevent battery drainage. Then I found this cable and it seems to be a perfect solution as long as it doesn't blow any fuses or devices I'll be happy. Of course my purpose is so that my dash cam can record 24/7 while still being connected to the head unit for easy playback. The cables data / power side is plugged into my head unit with part time power while the power only side of the cable will be optionally plugged into my always on cigar lighter so I can plug it in to it when I park in remote public parking lots for more than an hour so I have non-stop recording available in case of accident damage or burglars since the recording disc is in the camera. Sort of a remote security camera you can point where ever you park. I can even park it to see who's dog is pooping in my yard etc.

I bought some self-adhesive LED lights to put behind my tv,and of course the usb didn't have enough "juice" to power them (almost no tv does!) So I had to combine the power of the 2 usb ports into one,with this gizmo.Well it still has JUST enough power to make the lights work.However,even with this thing,when I tried to turn up the LED light brightness all the way,I got a usb power error message on my tv,and the lights went out! (but eventually went back on w/ some tinkering around with them, plugged into an actual outlet) so be careful if this is what your purpose is for,led light power from the tv.

I bought this USB cable for use with a Franklin T9 Hotspot. The hotspot has a tendency to cause its batteries to become "spicy pillows" if you leave it plugged in. It should be able to run without a battery installed, but my USB port couldn't provide enough power to do so. Once the hotspot was under load, it would shut itself off. With this cable, I no longer see this issue, and am now able to run my entire household's internet through the hotspot. It's highly reccomended for any high power USB device using USB 2.0.
