USB cable data transfer speed help

Transferring from USB 3 to a SSD drive I have one cable that transfers up to 300mb/s, but all my others are around 30-40mb/s. I have bought new 10Gb USB cables but they all deliver the slower rate.

What cable am I looking for to get the faster speeds? I only want a shot 20cm cable as well.

Double right angled Usb C female to male extenders: do they exist?

Hello, I am looking for a right-angle Usb C extender cable as the title says, but particularly I'm wondering if there are any such cables that are right angled on both ends. I've only been able to find right angled male ends, and I've been searching for a while so I'm wondering if such a thing even exists, where the female end is right angled. Of course, I want them to be 3.1 or higher, preferably 20gbps, and slightly long at 7 inches. The standard ones I've come across are either too short or too long. Please help me find it

Struggling to decide on a good 140W adapter (UK).

Hi there,

Geniunely struggling to find a 140w adapter.

https://amzn.eu/d/0brd7QQe this one seemed good.

Then there's this 200W anker one I saw that looks good for the price too.

https://uk.ugreen.com/products/ugreen-nexode-200w-4-port-gan-fast-charger

I had a look on charging sheet, really wanted the slimq but thats out of stock. I couldn't find the 140w cuktech one either. Aohi looked good but I'm not sure.

My budget is around £50, and I'd be using it to charge a mbp and my phone at the same time, figured 140W would be good for that. 100W seems like it won't be enough.

Let me know if anyone has any good suggestions 🙏

Do multi-port desktop chargers actually make sense for multiple laptops?

I’ve been using separate chargers for every laptop/device, and the power strip behind my desk is getting ridiculous.

I picked up a Cuktech 30 Ultra to try cleaning things up a bit. Main reason was the dual 140W USB-C ports and 4 total ports. It also has a little screen that shows watts per port, which I thought would be a gimmick, but I actually keep checking it to see how power gets split when I plug in another laptop.

Anyone here using one charging station for multiple laptops long term? Does the power allocation stay reliable when everything is pulling at once, or do these start throttling or overheating after a few months?

Or are you still using one charger per device and just living with the cable mess?

Best USB-C tester as of May 2026?

Looking to finally upgrade my AVHzY CT-2. What are the community favorites?

My constraints:

  • Test both power supplies and cables (Just basic resistance and type is fine)
  • Power: up to 100 watts. Anything more is extra.
  • Budget: $150ish
  • Fairly portable, so it does not have to have internal load tester

I did my homework, and these are the ones I'm seeing consistently coming up:

  • POWER-Z KM003C
  • ChargerLAB Power-Z C240
  • Fnirsi FNB58 BT: I know this has been a favorite due to Bluetooth, But I recall people preferring the Charger Lab.
  • AVHzY C5 (red 20bit)
  • FNIRSI FNB-C2: Seems to be a newcomer, comparable to the KM003C?

Power bank Conditioner or how to keep your power bank alive

I have an Anker Prime 20,000m-Ah power bank that just died. I do not use this very often and when I needed it this last weekend it was dead and wont come back. I understand that these should be discharged and re-charged regularly, but who remembers to do that when it sits in a drawer waiting to be used?

The Anker Prime has a charging base for this power bank that I though could be used as a conditioner, but the descriptions do not indicate anything about that. And it seems that through very little research that these type of batteries cannot be "conditioned" like one might for a car battery that sits for long periods. However, what I understand is that one can burndown a power bank at lest every couple months and and recharge to keep it alive.

So is there, or why is there not a device you can plug a power bank into that does this discharge/recharge cycle automatically so the power bank is always ready to go?

Usb C to Magsafe?

My MacBook charger recently fried because of an overvoltage issue, and buying a genuine Apple charger isn’t really possible for me right now since they’re pretty expensive here.

I’ve been looking into USB-C to MagSafe solutions, and it seems possible to use a good quality USB-C PD charger from brands like UGREEN or Anker together with a USB-C to MagSafe cable/adapter.

What do you guys think about this setup? Is it safe/reliable long term, or should I avoid it completely?

Would appreciate real experiences or recommendations.

Anker, Ugreen, AOHi and Chubby, which premium brand is YOUR go to? Name your own brand as wel.

Coming from Norway, my general pick of really high-end "Premium" USB cables are, from my experience... very limited. Brands like Linocel, Exibel (never heard of them? yeah, very niche) etc are really, really trash and pretty much the only solid "high end" brand I can buy in-store is Anker, and even that is limited in models.

So, for my needs I am seriously starting to look for brands outside of Scandinavia that ships to Norway. Mainly charging bricks, power banks and USB C and/or A (combo?) cables that can deliver 30-240W (For smartphones, tablets and laptops) and/or can transfer data at high speeds (Thunderbolt/USB4)

But I am unsure which brands is perhaps the one I should bet on, I see that many praises AOHi, and Chubby I just recently became aware of to be truthful.

But I would like to read what the community here has to say, what is your brand and why? Can include any brand you feel is great (No bias here)

Can a phone destroy a usb-c charger?

I've had an extremely bizarre situation last night. My Nintendo switch usb-c charger broke. It only charges intermittently. It would do the same with my phone, any other usb-c device and no matter what socket I plugged it into. The charger is no more than a month old

I borrowed an identical charger from my friend and it worked, so I plugged my phone into it and left it overnight. I've woken up and my phone hasn't charged past 15% and now this charger has the exact same charging issues as the last

My phone has admittedly been a little busted up for a while now and the screen does have some pixel-ly distortions so I'm wondering if a damaged phone could have broken both of these chargers so quickly? No issues with overheating or anything like that, just with the display.

How to wire my desk setup?

I'm looking for advice on the best way to wire the components of my desk setup to each other. I want a single cable to my computer which drives my monitor at 4k 120hz, connects to the various peripherals shown in setup 1, and charges the computer.

The monitor has two USB-A SS ports (I think 5Gbps) that a computer can use if using USB-C for video. If HDMI or DisplayPort is in use, the monitor has a USB-B SS port (I think 5Gbps) that can be connected to the computer/dock to run data to the ports. I use this port in setup 2, but "backwards", with the dock's host port going to it. Setup 1 is the same, just going to one of the monitor's USB-A ports instead. I did a basic test to verify set up 1 works, but haven't done in-depth performance testing. I can't test setup 2 since I don't currently have the required cable. These odd setups have some advantages, shown in my image.

Setup 3 is very different, basically a traditional setup, just using the monitor's USB-C video port (which outputs 90 Watts) as a power source for the dock/computer, rather than a wall power brick.

I'm looking for reccomendations on which to choose. Would any of the setups cause any issues with speed, reliability, functionality, or anything else? Are there any major considerations I'm missing from my list?

---

Miscellaneous notes:

-The backup SSD makes backups once daily in the background, so speed is not very important. It's not like I'm editing video off of it or anything.

-I want only one cable going to the computer, so I don't have an option with computer to dock and separate computer to monitor.

-I know I'll receive comments that setup 3 will provide less power to the computer than setups 1 and 2, and it does (72W vs 90W), but my computer only accepts up to 70W, so this is irrelevant.

Details on the components:

-Computer: Macbook Air M4
-Docking station: MOKiN 15 IN 1 Docking Station With 8K Resolution (https://mokinglobal.com/products/15-in-1-usb-c-laptop-docking-station)
-Monitor: Acer Nitro XV275K P3 (running at 4k 120hz)

Need female usb-c to female usb-c adapter

I am looking for a usb-c female to usb-c female adapter that read and write and charge no matter what orientation the cable is plugged in.

I looked on Amazon and every single one states that if the adapter doesn’t work you have to unplug the cable and flip the cable.
