TechRadar Verdict

The Iniu PD 22.5w 20000mAh is not the biggest power bank on the market and the lack of super-fast charging might put off Android owners who can take advantage of faster charging rates. But this is still a great battery for juicing up phones on the go: its capacity is pretty remarkable, given its affordable price point, and it offers one of the best power-to-weight ratios we’ve seen, even if it is still quite heavy to sling in a pocket. Ultimately, if you want to be able to charge your phone for days but don’t want to spend wads of cash, this is an excellent choice.

Pros

  • +

    20,000mAh capacity very decent for its price

Iniu PD 22.5W 20000mAh review

The Iniu PD 22.5w 20000mAh isn’t the most capacious power bank on the market. But for its price, it will give you a whole lot of charges for not much money.

The Iniu PD 22.5w 20000mAh doesn’t rock a ridiculous number of features, but what’s there is impressive, especially for the price. First of all it has a whopping 20,000mAh Lithium Polymer cell inside, which accounts for its bulk, which means it should keep charging your devices day after day. Additionally, with a USB-C and two standard USB ports, you’re able to charge three devices at once.

To really put the Iniu PD 22.5w 20000mAh through its paces, I took it away to a music festival and used it to charge my iPhone 12 Pro over the course of a long weekend. Charging my phone up to 100% once a day on the Saturday, Sunday, and Monday only depleted the battery down to 54%, meaning you may well get almost a week’s worth of charge out of it if you aren’t fully draining your phone every day. That’s more than many of the best power banks can deliver.

On top of this, the Iniu PD 22.5w 20000mAh offers 22.5W charging, which is fine for the max charging the best iPhones require, although falls quite a way short of the 100W that the best Android phones like the OnePlus Nord 4 are capable of drawing, and means you won’t be charging a MacBook off it. In practice though, during a separate test, this meant it took 128 minutes to charge the iPhone 13 Pro’s 3,095mAh battery, which could be much worse.

Looks-wise, the Iniu PD 22.5w 20000mAh is a nice-looking battery, while not being so stunning that you’re going to be terrified of damaging it. It comes with a pleasing matte finish in either black or white. An LCD screen on the front of the device tells you exactly how much charge is left – far more useful than the series of LEDs some power banks employ.

At an inch thick and weighing 12.8oz (323g), this power bank has got some serious chonk to it. It also doesn’t have any IP weatherproofing, meaning you really don’t want to drop it in any puddles. In spite of this, it still sat comfortably enough in my pocket as I wandered around and boogied at the festival, and it survived a full day of torrential rain in the pocket of my damp jeans without much worry.

For an affordable power bank, the Iniu PD 22.5w 20000mAh offers a serious amount of juice. While it doesn’t provide features like fast charging or wireless charging, it’s an obvious choice for anyone who wants to keep their phone topped up during a week away.

Should I buy the Iniu PD 22.5w 20000mAh?

Buy it if…

You need a big-capacity battery that doesn’t cost the earth
There are (slightly) bigger power banks out there, but few of them are this reasonably priced, costing a fair bit more for a modest increase in total charge.

You want to charge multiple gadgets at once
With its USB-C and dual USB ports, the Iniu PD 22.5w 20000mAh Power Bank will happily charge your phone, smartwatch, and earbuds all at once.

Don't buy it if…

You want to charge your phone, fast
The Iniu PD 22.5w 20000mAh Power Bank is only capable of 22.5W charging, which is much slower than many Android handsets are capable of these days.

You want a compact, lightweight power bank
At 12.8oz (363g), the PD 22.5w 20000mAh Power Bank is a fairly weighty battery. It can still fit in a pocket, but if you want something you can just carry around until you need it, it might be worth looking elsewhere.

Iniu PD 22.5w 20000mAh review: Also consider

Anker Prime 27,650mAh Power Bank (250W)
At $179.99 / £179.99 (roughly AU$261.35), affordable it ain’t. But if you want the perfect combo of ultra-high capacity and insanely fast charging, your best bet is the Anker Prime 27,650mAh Power Bank (250W). It can charge a MacBook Pro M2 to 50% in just 30 minutes or charge an iPhone 16 more than four times, which makes it a beast of a power bank.
