Been eyeing up a capacious power bank to take on your travels? This INIU unit is quite well-regarded and comes with the benefit of a huge 20,000mAh capacity that should be good for charging everything from your phone to your laptop and more in quite a small size.

You can grab this large capacity power bank for just £15 on Amazon thanks to a 49 percent discount that auto-applies at checkout, which is the best price this unit has been for a couple of months.

The big thing, or rather not, with this INIU unit is the fact it combines a large 20,000mAh capacity with a small size that they say makes it the most compact power bank of its capacity. That makes it especially useful for power users on the go who need the oomph for multiple charges of phones and laptops in a pinch.

It can also provide up to 22.5W of power delivery for supported devices, with support for PD and QC among other fast-charge protocols to ensure devices are topped up in a reasonable amount of time – INIU says it’ll charge an iPhone 16 to 60 percent or a Samsung Galaxy S24 to 70 percent in just 25 minutes. That’s quite speedy.

The USB-C cable is integrated with this unit, and is detachable for added portability, so you don’t necessarily need to bring one out with you if you’re in a hurry, although there are also another USB-C and USB-A present for charging more than one device at once if you need time.

If you want to grab a capacious and speedy power bank for a bargain price, this 20,000mAh INIU unit for £15 is a steal from Amazon.
