Anker 7-Port USB 3.0 Data & Charging Hub
That’s not the only electronics I’ve been relying on that takes up desk space, though. Many years ago I bought myself a cheap little USB hub that provided power and data transfer. It was so old that it may even have been USB 1.0. Worse it had a clear case with a nice big blue LED in it. That sounds fun, right? Well no, not so much if you’ve worked in electronics assembly. The romanticism of a PCB is somewhat lost when you’ve slaved over a flow solder machine during the height of a heatwave. Britain has many advantages but understanding why air conditioning can be useful in a generally cold country is not one of them. Being able to see the PCB inside my gear has never really excited me that much.
Even better, a bright blue LED that’s powered on 24x7 is actually a serious problem when it’s on the desk in your bedroom. I watched a TED lecture a few years ago about the science of sleep. One of the key pieces of advice this guy gave (apart from the idea that lack of sleep might actually make you mentally ill) was that blue light sources were absolutely awful for sleeping. When your brain detects blue light it thinks it’s morning, those wavelengths trigger the hormones that wake you up. I tested my light situation and found that I could actually navigate around my small room just by the light given off by that one LED. I have pretty good night vision but not supernaturally so. Getting that out of my room genuinely helped me get more and better quality, sleep.
It was fine on my desk in the living room though. The problem now was that today’s devices are much more power hungry. I have a Hudl 2 Android tablet which is notoriously bad at power consumption. You can’t really expect that much from a tablet produced by a supermarket chain. However it’s been pretty good for the price and suits my needs. If they hadn’t cancelled the line I’d certainly have upgraded to the Hudl 3 when it came out. My feeble little USB hub of glowing horror couldn’t really provide the juice for this tablet or even my aged Galaxy S5 though. All this is a long way of getting to the important point, why on earth would you pay for a big USB hub? Do you really need such a thing? In short, yes, yes you do.
Identifying my requirements and confirming what’s available
I wanted to have my cake and eat it, getting everything I really needed for the best price. Preferably without an insomnia causing LED attached (it’s for my desk in the living room but that could change in the future). First, then I did some research into the various types of USB, power requirements and data transfer speeds and so on. I needed to work out what requirements I actually had, what did I genuinely need out of this device, what would I like, which features were negotiable. I like to know that I’m getting value for money and that always has to start with making sure you’re only paying for the features you need. For instance, I don’t need some gigantic device that would charge twenty tablets at once.
- What type of USB slots did I need 2, 3 or was there Type C issue I needed to be aware of?
- How much power would I need those slots to supply? I knew it’d be more than my USB 2.0 hub provided.
- Was it worth having a combined data and power hub? Would it be better to have two separate devices?
- How many ports did I need? How many devices did I need to charge and how many slots for data transfer would be useful?
- How small a device could I get and what form factor should it be?
Types of USB – 2, 3, 3.1 & Type C
- Do not worry about Type C – it’s just the name of the new reversible connector type (you can plug it in either way up).
- The other end of the cable will still plug into your existing USB 2 or 3 slots which are Type A
- USB 3.0 should be the minimum standard if you’re buying a hub now, it transfers data and power at a higher rate
- I would not bother buying a USB 2.0 hub, powered or not unless you are truly desperate, the power demands of your devices are too high and backing up data across them is too slow
- Be careful that when you get a USB charger it supplies at least 2 amps PER SLOT. Many chargers only supply 0.5 amps per slot so they charge your devices slowly (if at all).
- Some chargers can supply 2 amps for one slot but not for the others, usually, you see this on ones that are just a plug to go in your wall socket and you plug your USB cables directly into it
Power Requirements
One Device or Two? How many ports do I need?
I knew that I wanted to be able to charge my devices but that I also wanted to be able to plug in my phone and tablet to transfer small amounts of data and my hard drive for backup purposes. However, that could be accomplished by a data hub and a powered hub that are separate. In my bedroom, I have an Anker hub that just supplies power for charging. That’s on my bedside cabinet and it’s where my phone and tablet get charged overnight. I have nice long cables on it so I can lie in bed watching Netflix on my tablet, wondering why I’m doing that as there’s no position that doesn’t result in me hurting my back. I also have a USB fan that’s plugged in which is nice and quiet and offers good cooling in a room that’s ridiculously hot.
I looked into whether there were similar devices I could get, perhaps a cheap one with fewer ports. If I could get a small power hub and a small data hub that could be quite handy as I could then take the data hub travelling with me slightly more easily.
However, I couldn’t find any combination which made sense in terms of space on my desk, weight and most importantly, cost. I quickly settled on a combined hub. I need to charge my tablet, my phone and my wireless headphones. It’d be helpful to be able to charge more and leave my hard drive plugged in and powered up all the time. If I make more use of that it’s nice and portable (it’s a WD Digital Passport so it’s about the size of my wallet before I empty out 5 months of receipts).
Device Size and Form Factor
Decision Time
I knew already that I’d had good experience with my existing power only Anker hub. It supplies 40 watts over 5 ports so it can charge all of my devices at top speed. When I’m buying my own tech I always go to one source – The Wirecutter. These guys have an excellent and well-deserved reputation. They write long, lab style tests that they keep updated regularly with comments about the tech they’ve recommended. They pick their favourite, they tell you why they’ve chosen it and they tell you what the best alternatives are in case you have different needs or something that came a close second is on sale. I never rely just on one site for my information, though. I’m always looking for comments that will knock down the tech I’m looking at in a helpful manner. Other users are a great source of real-world experience as they’ll sometimes point out problems they had that resonate with you. For instance, if I’d read a review of my first USB hub that said ‘It looks kind of fun but that blue LED will actually keep you awake at night if it’s in your room.’ I might have done a little more searching and picked something different.
Their reviews recommend 3 different Anker hubs that are very similar to each other. This gets a bit confusing because I bought a product Anker describe as a 7-Port USB 3.0 Data & Charging hub. It actually has 7 data/power ports and 3 additional fast charging ports for ten in total. There’s a smaller one that only has 7 ports in total, only one of which is fast charging (and does not supply as much power as the first one). Finally, there’s another with ten ports with 9 data and 1 power port. It’s important to note that the data ports DO supply power but at lower values than the fast charging points. Confused? I’m not that surprised. Suffice to say all of these can charge your devices but it’s worth picking the one that best suits your needs. The prices are pretty good and they’re all quite small. Mine is only a few millimetres longer than my phone and has plenty of room for all ten ports. I was very happy with the price, size and form factor.
Any buyers remorse?
I haven’t really had any buyers remorse, as you so often do when you actually use a new gadget. Sure, in a perfect world I’m trying to keep my costs down at the moment so I would have been perfectly happy with half of this device. The same power per port, four or five slots and data would have been fine. USB 3.1 would be worth looking out for in the future but I don’t think it’s worth worrying about at the moment for most people. Until you have devices that can make use of the power or data transfer speed it’s not really an issue.
