If you have a laptop that you want to get online when away from home or the office then a mobile broadband dongle such as the Vodafone K5161z could be the ideal solution.
It’s a simple, highly portable device that can provide a 4G-powered internet connection to Windows and Mac computers.
It has a lot going for it – including the lack of reliance on either a battery or mains power, but it’s not without its limitations, so read on for a full review and overview.
Design

The Vodafone K5161z looks like most other dongles, which is to say that it looks like most USB sticks, because that’s essentially what it is – a small 93.8 x 28.6 x 13.5mm black oblong that plugs into the USB port of a computer.
That tiny size (and super-light 28.2g weight) means it’s even more portable than typical mobile broadband devices. You can just chuck it in a bag or pocket and forget about it until you need to use it. If you store your laptop in a bag then you could simply store this alongside it, as it should easily fit.
Setup
Setup is about as simple as it gets since you just plug the Vodafone K5161z into your computer for instant connectivity. And it works with most Windows and macOS devices, which in other words means it should work with the majority of laptops and desktops.
Of course, given that it’s designed to be portable it will in most cases be laptops that you use it with – though if your Wi-Fi is ever down at home then it could be a handy backup for your desktop too.
Performance

The Vodafone K5161z is a Cat 4 device, supporting download speeds on 4G of up to 150Mbps and upload speeds of up to 50Mbps. Those are solid speeds, though of course they’re nowhere close to what you’d get on 5G or the fastest wired broadband connections.
Those are also the peak speeds, so in most situations your actual speed will be quite a lot lower, but should still generally be fast enough for most internet tasks. That’s assuming you have a 4G connection, but Vodafone’s 4G network covers over 99% of the UK population, so you should do in most places.
Unlike some other mobile broadband devices such as the Vodafone 5G Mobile Hotspot, the Vodafone K5161z can only get one device online at once, and since it has to be plugged into a USB port it only works with devices that have those – and more specifically only Windows and Mac devices.
That’s quite limiting, but on the flip side it also doesn’t need a battery or mains power, since it’s powered by the device you plug it in to. So you don’t need to worry about charging it, which is really handy.
Features
The Vodafone K5161z is light on extra features, but it does have a microSD card slot, so you can essentially add storage to the devices it’s connected to by putting a card in. As it’s a portable device it also gives you an easy way to move files from one computer to another – essentially giving it functionality more like a normal USB stick, though you’ll have to buy a microSD card separately to do this.
Alternatives
If you’re buying from Vodafone then the main alternatives are the Vodafone 5G Mobile Hotspot and the Vodafone 4G Mobile Hotspot, which are what you might want to opt for if you want to get more than one device online at once. These can each get up to 32 devices online wirelessly, and the 5G version supports higher speeds.
However, they also both have a battery that needs charging, and they’re inevitably larger, making them slightly less portable.
On the dongle front, there aren’t any other options from Vodafone at the time of writing. There are alternatives elsewhere, such as the TCL Dongle 4G, but this again offers similar performance, so there’s not much to choose between them or most other 4G dongles.
Conclusion
The Vodafone K5161z is a very standard, conventional 4G dongle. That’s no bad thing. It does everything it needs to and with the addition of a microSD card slot even a little bit more.
Its main issues – other than the lack of 5G or the fastest 4G specifications – stem from the very fact of it being a dongle – namely the limited number and type of devices you can connect it to. But if you mostly just want to get a laptop online then this is an ideal option.
