Product overview

• 7 port hub
• USB 2.0 full speed
• Mains Powered
• Plug 'n' play
• Triangular design for better accessibility
• Adhesive back sticks to any surface

The triangular 7 port USB 2.0 hub is designed so the USB ports face upwards to enable better accessibility to the ports. Converts one USB in to 7 ports. The bottom of the hub has adhesive pads so it can stick to any surface making it skid proof. The hub can be used with both PC and Mac and has a recessed power port if your peripherals need additional power.

Rated 2 out of 5 by from Flaky USB Connections I've had 4 of these now, same type, the triangular one, but ranging from 7 to 4 ports and all of them suffered the same problem of intermittent USB connections. All were powered, and as a pass through to charge a device it has worked flawlessly, however when connection a USB wireless key, it would occassionally fail to be picked up, the same with a low powered USB hard drive and a phone, I ended up having to connect them to the case ports. I thought I was being unlucky having 4 of them, but having read the reviews maybe it is a design fault. Off to but a new hub now (the other Cerulion seems to get good ratings, so I may try that one).

Rated 1 out of 5 by from Works well until it doesn't Bought this about 12 hours prior to writing this review, and have been using it for around 8 hours. One of the USB ports has already stopped working. Power is still passed through it, so I can still use my fan with it, but no device will be detected through it. This is COMPLETELY unacceptable. I cannot fathom how a device could be so poorly designed that it develops a fault within 8 hours. That's RIDICULOUS. Save your money.

Rated 2 out of 5 by from I bought this USB hub, because on my office I have a million and one things that need plugging in. I do have about 6 on my PC, but with the addition of 3 printers and mobile devices such as iPad, and phone I really wanted something to extend that range. First of the Cerulian is a really, really nice looking piece of kit. It's unique shape and materials show that I was very well thought out. It comes with an adequate amount of cable, including power to help power devices that may need a charge. However it doesn't really work that well. As mentioned, I wanted something to charge my phone and iPad as I have them docked on my desk. The power supplied by the hub is nowhere near adequate for this, so doesn't charge the iPad. Secondly when updating content to the iPad, it fails. Data transfer is impossible via iTunes, or any explorer based transfer using standard USB sticks. Overall for general USB extending this is completely useless.. the only thing that seems to work, is my WiFi dongle. Even my wireless keyboard needs resetting every few hours. So, looks nice, and cost is low, but it's really worth spending a bit more to save the frustration, and pulling your hair out. But with the money saved I can now buy a wig.

Rated 3 out of 5 by from Works well until you want to do any form of data transfer between hard drives then it fails and no longer see's the drives. Plus the adhesive pads don't stick for long.

Rated 3 out of 5 by from I have just bought a Griffin iMic and run out of ports on my Belkin four-port USB hub. I decided to put the Belkin aside and use a seven-port as my main hub. I was drawn to this Cerulian Technology N11JB hub by its compactness and price. It works but it's not quite what I expected. The Cerulian's power supply is somewhat weak, supplying only 2 amps. The USB 2.0 spec allows bus-powered devices to draw up to half an amp each, so a proper seven-port hub should have a 3.5 amp supply. (Slightly more since the hub itself needs a fraction of an amp. For comparison, my Belkin hub has an ample 2.6 amp supply for its four ports. Naturally, I can't swap the supplies!) This may not be a problem for you if you plug in mostly devices that use little power, such as USB sticks, or have their own power supplies, such as desktop hard drives and printers that do not draw power from the hub. It's also a rather noisy power supply. My iMic can be used to record sound and it records a distinct buzz when plugged into the Cerulian hub but not when plugged into the Belkin. The buzz goes away if the power supply is disconnected. In that setup, the hub and any bus-powered devices plugged into it draw power from the computer, though this limits bus power to a fraction of an amp. (My iPod Touch does not charge when the hub's power supply is disconnected.) The hub doesn't seem to be doing anything untoward to the data going through it, so its power supply should be fine as long as you're not going to record any sound through the Cerulian or try to power much with it. A typical 2.5-inch bus-powered hard drive can draw over an amp while it spins up. A bus-powered DVD burner can draw 1.5 amps. The salesperson at Maplin cheerfully told me I'd be able to do these things, but the power rating printed on the Cerulian's mains plug says no, not at the same time. The hub's USB plug has a thick plastic grip that I like. The cable is attached permanently. At 1.5 metres it is more than long enough but if you damage the cable you junk the hub. Ideally the cable would have a plug at both ends so that replacing it would be cheap and easy. The arrangement of the ports is good and keeps the hub compact without causing problems for wide plugs. More hubs should have the ports stacked like that. Surprisingly, the Cerulian is technically two hubs in one. It may look like one hub but a computer program that probes the USB bus will show you two hubs wired together. Presumably this is to keep costs down, since seven-port circuitry is less popular and probably costs more as a result. (More than twice as much as two four-port circuits. Gosh!) If you number the Cerulian's ports from the end where they're close together, ports 1, 6 and 7 go to the first four-port hub. That hub's remaining port is wired to the second four-port hub, which has ports 2, 3, 4 and 5. This has performance implications. Each USB 2.0 hub circuit has its own transaction translator (or TT) which converts slow USB 1.1 signals to faster USB 2.0 signals so that they can share the same cable to your computer. Every USB 1.1 device that shares a USB 2.0 hub shares its TT (hence bandwidth) with other USB 1.1 devices plugged into that hub (barring rare expensive hubs that have one TT per port) which means that some bandwidth-hungry USB 1.1 devices can slow each other down while leaving most of the faster USB 2.0 bandwidth unused. With the Cerulian's two hubs (therefore two TTs) you can in principle get twice as much USB 1.1 bandwidth by sharing slow but bandwidth-hungry USB 1.1 devices (Griffin iMic, webcams, floppy drives, old USB sticks and memory card readers etc) between the two hubs. For example, you could plug a Griffin iMic into port 1, 6 or 7 and a floppy drive into port 2, 3, 4 or 5 and the two won't compete for bandwidth. This could be good for me if I normally used more than one USB 1.1 device, but I don't. Two hubs can also be a hindrance, since USB 2.0 signals that go through ports 2, 3, 4 and 5 go t...

Rated 1 out of 5 by from totally unreliable Individually, the various USB ports on this hub work occasionally (although at this moment none are functioning) but I've never managed to get them all to work simultaneously. I saw another reviewer describe it as a "rubbish piece of kit" - pretty much sums it up. Steer clear.

Hi, does this hub come with a separate power supply, or do you have to buy one. If you have to buy one which one is it & do you sell them. Kind regards.

Why wont this hub work with iphones ?? 

Asked by: byork123
If you are using this device to have multiple charging items at the same time I would advise that this item cannot provide enough power to charge the iPhone.

This device doesn't appear to work at all with my iMac. I did what it says to with the "very limited" user guide supplied with the kit.

I would advise returning the unit for testing.

What is the power (volts and amps) output for each USB port assuming you connect the extra power supply?

Asked by: Chris
This would be 5V and 2000mAh across all the USB sockets.

Bought Cerulian 7 Port Triangular Hub Jul/Aug 15; won’t recognise external drive when plugged in, makes other attached devices invisible. Have I corrupted the hub driver? Drive is recognised when directly connected to Lynx 10 tablet running Win10.

Asked by: Aldo
Yes. This has happened to me and others. Quite annoying. Has also happened to me with a external DVD drive taking two USB connections from the Hub (one for data and one for power). I think the problem here is that the hub is being overloaded decides to upset the rest of the USB chain, and when it comes to drives, somehow it is affecting the internal drives . . . . . the external Power Supply (which you have to buy separately) is 2amp which should be plenty larger enough. All together a bit hit and miss . . . .
