INIU’s 20,000mAh 45W power bank sits in the brand’s higher-output range, competing with the likes of Anker’s fast-charging packs for people who want one battery to cover both phones and more demanding gadgets. The headline here is 45W USB-C fast charging, which is the sort of output that can keep up with many USB-C laptops and tablets, not just top-up a handset. The integrated cable helps if you’re fed up of carrying spares, while the digital display is more informative than the usual four-LED guesswork, giving you a clearer read on remaining charge.

Who is this for?

Commuters and travellers who charge multiple devices, or anyone with a USB-C laptop that benefits from higher wattage. If you only ever charge a phone overnight, a smaller, lighter pack may make more sense.

• 20,000mAh capacity — enough for several phone recharges, with headroom for longer trips.
• 45W fast output — better suited to tablets and some laptops than basic 10–20W banks.
• Integrated cable + digital display — fewer extras to pack, and a more precise battery readout.
