INIU 20,000mAh Power Bank is Company’s Smallest, Can Fully Charge a Smartphone Up to 4-Times

Long journeys highlight how quickly your phone can drain, with all those maps, images, and texts eating away at the battery like there’s no tomorrow. The INIU power bank, priced at $19.79 after coupon is automatically applied at checkout (was $33), comes to the rescue, packing 20,000mAh into a body measuring 2.8 x 4.1 x 1.2 inches and weighing only 11.1 ounces. Tuck it into a jacket pocket or side compartment, and it will sit quietly until you need it.

Its high-density cells are capable of packing a lot of power into such a small footprint without losing output quality. In general, a full charge will last your iPhone 16 up to four complete recharges or your Galaxy S23 up to three, but in practice, it all depends on screen brightness, apps, and so on, so don’t be surprised if it lasts you a full day of mixed stuff before needing a top-up.

Recharging is a continuous 22.5 watts using PD & QC protocols so your phone charges up faster than with typical banks, which is good. One end is lined with three ports, two USB-C and one USB-A. Two or three devices can share the load, consuming up to 15 watts total. The bank also includes a short braided USB-C cable with a wrist band, eliminating the need to rummage through your luggage for extra cords or get held up at security.

Rather than an ambiguous battery indicator, the front boasts a handy LED display that shows you exactly what percentage is remaining. That way, you can quickly assess whether it will withstand another gadget or if it requires some TLC on its own. Recharging the bank takes about six hours with a regular wall adapter, which is quite fair. The 74-watt-hour rating is airline certified, so there’s no need for any further paperwork.

Hikers and festival-goers appreciate the built-in torch for late-night trips to the restroom or getting to your car in a parking lot. The outside case is durable enough for daily use, and the entire thing stays cool even when left on for extended periods of time.
