USB Splitter Cable,USB A 2.0 Male to Dual USB Female Y Splitter 2 Port Hub Adapter for Car/Laptop/LED/Charging Etc (2pcs)

This little splitter is the perfect solution for adding a memory card to output your TESLA TeslaCam videos to a memory card. Stop worrying about whether the splitter is capable of USB 2.0 or 3.0 because for this application USB version is irrelevant—there are very few devices that utilize USB 3.0 throughout and that includes the Tesla Model 3 which supports USB 2.0, and for good reason (power demand). Unless EVERYTHING in your setup supports USB 3.0—that means the “host” or “from” computer or device, all the devices and all the cables. Unless this is true, worrying about USB version is a waste of time. Putting a 3.0 cable or splitter in a 2.0 system will NOT change performance. Putting a 3.0 device on a 2.0 host will NOT change performance. The host and everything in the string of devices must all be 3.0 to benefit from any improvement in throughput. Read on a bit later to find out why.So stop fretting and just place your order for this splitter. I can attest to the fact that it works and it is just what it needs to be: inexpensive, small and functional. I regularly plug my USB memory cards (up to 256Gb) into the data side of the splitter WHILE my phone is charging on the same USB host through the splitter. But, as with anything computer, you need to READ the instructions when you install it! For the Tesla, plug your charger into the thin cable and plug your USB memory device into the thick cable. AGAIN, whether or not it is USB 2.0 or 3.0 is irrelevant because the Tesla ONLY supports usb 2.0 power and data levels. It doesn’t matter anyway regarding speed, because all of the data is buffered out to memory anyway and USB 2.0 far exceeds the needed data rates and throughput…more speed or power would just be a waste of unused potential. It’s too bad more people don’t read about USB standards because a bunch of money gets wasted on unusable potential.Also, complaints about slower charging are inaccurate or the users have likely not read the directions or are trying to use or charge devices inappropriate to the “host” USB device being used—in this case the Tesla. ALL devices connected to ANY single USB port through any splitter or hub MUST share power unless the hub or splitter itself supplies additional power. Remember the Law of Conservation of Mass and Energy? Well, the USB port is subject to that same basic law of physics. Energy coming out of a USB port heading toward your devices must be shared by all devices connected to that host port—more energy can’t be just spontaneously appear for use in that system-it either has to be shared or augmented. In this case, you don’t need to augment power because all you are doing is using one cable for charging (thin cable) and one cable (thick cable) to plug in ONE USB memory card. Memory cards use so little power that there is little chance that it will have ANY effect on the charging going on in the other cable.Again, you will notice that one splitter cable is thick and one is thin. THEY ARE NOT INTERCHANGEABLE! THIN is for CHARGING and THICK is for the memory card. Why are they different sizes? This is because they contain different numbers of wires. The THIN side is for CHARGING only and you can only have one high-drain device like a phone charger at a time from any USB 1.0, 2.0 or 3.0 port. The thin cable in this splitter contains only two wires: +5vdc and ground. Don't expect to plug in two phone chargers to ANY splitter (even on USB 3.0) unless the splitter itself has a separate power supply that is plugged into line power (100, 110, 240). Why? USB 1.0 and 2.0 ports supply only 500ma-just half an amp at 5volts or 2.5 Watts of power (minimum of 3.5vdc and maximum of 5.25vdc). You can run a dozen or more memory cards on a half amp, but not more than one high power device (like a phone charger or a portable dvd drive) at a time. A “host” device with USB 3.0 supplies 5 volts at 900 ma-almost a full amp but that power still has to be shared among all devices connected to that one 3.0 port. 5 volts at 900amps consumes 4.5 watts of power. Devices like phone chargers will “take” as much power as they can from the circuit leaving little for additional devices. For example, the Samsung Galaxy 9 wants a full amp at 5 volts when it is plugged into the wall, but when plugged into a host USB 2.0 port on a computer or Tesla (if the computer even allows charging, many don’t), it will always be limited by the USB spec, which is 500ma at 5 volts.Now, in the thick cable there are 4 wires; more wires in the cable means a thicker cable! For data, USB 3.0 uses 9 wires as opposed to the 4 wires in USB 2.0. BUT, USB 3.0 charging uses still only one 5vdc wire and a ground. Power supply and charging is complicated with USB. The controlling device processor tests the port to determine maximum power and will throttle down or even turn off devices pulling too much current.Maybe this is unneeded detail because what you really need to know is that these little splitter cables are perfect, do exactly what they are supposed to do when properly installed and support ALL USB devices and ALL USB phone chargers regardless of USB version because all USB data and power standards are fully interoperable. By the way the cables in this splitter unit are short because first you don’t need a bunch of cable rolled up in your TESLA consol, AND the shorter the cables at a given wire size the better the performance in both speed and current.I hope this helps people looking for a splitter for their Tesla Model 3 make a rational choice and save a few bucks at the same time.

Very low quality

Bought this mainly for expanding my car USB or which is always taken for Apple Carplay hookup. The Apple Carplay works well with the thick wire connector. While the other port can be used for charging only for the passenger's device.Length is perfect for this purpose too. not too long like the other splitter I tried before. Recommended.

Set up with a wireless charging pad. Followed instructions. Plugged in thumb drive that gets Tesla requirements. Tesla throws error that thumb drive is too slow. Plug thumb drive directly into Tesla port, Tesla is happy. So the cable is the problem. Guess you get what you pay for. Cable is useless, as is 1 side of the charging pad. Good thing nobody likes me enough to ride in my car with me and charge their phone.

With only 2 USB-A ports up front, this is exactly the hardware needed to expand those ports. To allow wireless charging pads, sentry recording and still have an open port for other uses.

Bought these as my previously purchased wireless charger in the car worked intermittently on one side. This product fixed the issue and full functionality was restored. Splitter appears to be good quality and I got two for less than the price of one for similar products. It only took one of the splitters to resolve my phone charging issue in my Model 3 Performance.

It does not work when plugging the provided usb charger cable on model 3. So need to read the fine print - probably does work for wireless charging??

Cheap, splits what you need it to. Worked well in the Model 3 it was purchased for. You can never have enough of these things, and these have held up. Definitely a good ba g for your buck.
