Nebo 5K Powerbank Review scaled

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

I recently reviewed the excellent Nebo Galileo Air 1000 Collapsible Lantern and have reviewed several other Nebo products.

The Nebo 5K Powerbank is the most affordable option in their range of power banks, and as the name suggests, this is advertised as having 5,000mAh capacity.

Nebo excels with its lighting products and has some innovative power products, but this 5K power bank struggles to stand out from the crowd, with companies like Anker and Ugreen offering superior alternatives.

At first, I was very disappointed to see this power bank feature a micro-USB input. It is a legacy format that shouldn’t be used on devices in 2024. I was then relieved to see that you don’t need to use this port, as the USB-C port is bidirectional and can accept up to 10W input.

Beyond that, the power bank is very slim and weighs just 113g, making it a bit smaller and lighter than some of the alternative options I have listed further down.

It has more ports than most 5K power banks, with two USB-A ports complementing the USB-C and micro-USB ports. However, the output per port and maximum total output are quite low at 10.5W.

Finally, on the front of the power bank are 3 LEDs that indicate the remaining charge.


Like all power banks, you don’t actually get 5000 mAh to charge the device because most consumer electronics use 5V instead of 3.7 V. This, therefore, means the true expected capacity should be around 3700mAh.

Nebo also lists the accurate capacity of 18.5 Wh.

As far as performance goes, this power bank works as expected. My USB power meter shows up to 10W output for each of the USB-A and USB-C ports.

You can charge more than one device, but the maximum output is limited to 10.5W.

Price and Alternative Options

The Nebo 5K Powerbank is available from for £20.

While that is not a lot of money, there are superior alternative options.

The range of alternative options increases significantly if you move up to 1000mAh, but these will become thicker and heavier.


The Nebo 5K Power Bank isn’t a bad power bank. It works as advertised, and the very slim design will be appealing to anyone wanting something small and light for emergency power.

5K power banks seem to have fallen out of fashion, so there are not lots of alternative options from reputable brand names, but what is available is better value for money. The Nebo does have more ports than others, but with 5000 mAh, you are not going to be charging multiple devices for long.

Overall, while the Nebo 5K Power Bank works perfectly well, it needs to be in the £10-£15 range for it to represent good value for money.
