USB Hub USB Splitter USB 4-Port Adapter Extender for Laptop PC MacBook Mac Pro Mac mini iMac Surface

Works good.. Better to put it somewhere were it won't get bumped. Dongles can get loose. Read more

Product is exactly as described and works well so far. Read more

Great product and price .. no complaints from me! Read more

I like the fact that I can connect my tablet, phone, and external hard drive to it. Only thing that bugs me: it cuts off frequently, and I have to wait between 2 and 3 seconds for it to connect again. Read more

Length of course is very short would be better with longer cords Read more

Es perfecto para dispositivos USB 2.0 Read more

Honestly better than I expected information travels to this thing very well Read more

I've been using some of these for an indoor garden, to power some LED sticks, spread across a few schedule-controlled smart plugs, and the connection to the actual charger seems to become unstable, over time. The electricity going through it, despite being on grounded cords, mostly high (for USB charging blocks) amp bricks, appears to be dirty, and it has caused several sticks to become damaged. The splitter is not torqued heavily, although it is at an angle (and held mostly steady with twist wire), but not one in which the tension should be problematic. At first, I thought I had a bad batch of lights, as they occasionally flicker directly in the block, but I noticed that only ones taken OFF these splitters seem to have that problem in less than several months of use, so I suspect the current is unstable. Fiddling with the splitter's input, however, makes it more stable, but only for a limited time, and that's actually the reason I'm on, at the time of writing this -- to look for a replacement, soon. For extremely low-watt usage, it is probably ok, but even a few watts (I believe the light sticks are only like 1-2 watts, each; max of 6-10 sticks per brick, depending on the brick's rating), it appears to cause connectivity issues, eventually resulting in dim lighting (weak current) and/or rapid flickering (which seems to have caused the overheating of the lower-wattage (around 2.1 A) bricks, LED sticks themselves, and eventual damage to the diodes). While I did NOT buy these for data transmission, I can reasonably recommend NOT using these for sensitive low-end electronics without some sort of built-in voltage/power modulator (a phone? Probably fine, as they have capacitors and adjustable input, and the worst you might get is, "charging slowly". But unregulated electronics? Doubt it, unless I just got unlucky). For reference, they are kept on, like 2-6 hours at a time, with 10-15 minute off cycles, throughout the night (all night cycles are around 2 hours. I only leave them on longer, if I manually turn then on, during rainy/cloudy days). In the first pic, you can see how bright the sticks are supposed to be. That is an old DC-assisted brick I repurposed, when I needed faster USB support. In the second, you can see how dim the sticks are, on *this* hub, connected to 1 output of a 3.1 A brick. I had only just adjusted the input, barely 2 hours ago, at the time these pics were taken. This hub has been plugged into multiple brick ports, at least 2 different bricks, and even that other hub. It still does this. This one is 1 out of 2 hubs I bought from this brand. The other still seems mostly fine, and it is never moved, at all. That's why I believe the issue is material quality, and that the pins are not very durable. For comparison, the hub that doesn't (yet?) experience this issue, the one that is never moved, is in the third pic, and the sticks are dramatically brighter. Read more
