INIU 25000mAh 100W Power Bank Fits Laptop Power in a Surprisingly Small Shell

Laptop power banks usually feel like carrying a second device. Most high-capacity options that can actually push 100 watts sit well over a pound and take up more bag space than people want on a flight or a long work day. INIU’s P63-E1 model, priced at $30.59 after 49% off checkout discount (was $60), compresses 25,000mAh and real 100W USB-C output into a package that measures roughly 4.3 by 2.7 by 1.4 inches and weighs about 390 to 400 grams. That puts it closer in size and feel to a thick phone case than the brick-like packs most people associate with laptop charging.

One key USB-C connector can deliver up to 100 watts at 20 volts and 5 amps, enough to charge your gadgets swiftly. A second USB-C connector can deliver up to 45 watts, and a USB-A port can deliver up to 18 watts, which is plenty of juice for occasional use.

When you connect two USB-C devices, the overall output reaches 110 watts, and with all three ports active, it still manages roughly 80 watts. The input, so to speak, can handle up to 65 watts, which implies that a high-wattage wall charger may recharge the unit in roughly an hour and a half. Fortunately, it fits under the airline’s 100-watt hour limit, so you can pack it in your carry-on without having to deal with additional paperwork.

The top face has a bright digital readout that allows you to know how much power is left at a glance. INIU also includes a short, detachable 100W USB-C wire that can be used as a wrist strap or purse loop, which is a wonderful feature – no more worrying about splitting the cord in two.

Reviews that put this unit to the test found that it delivered well over 90% of its rated capacity in most cases, and it can even charge a 14-inch MacBook Pro from a low charge to around 70% in about half an hour, which is pretty impressive, and if you just need to charge your phone or a Steam Deck, it’ll do so at about the same speed as a wall charger.

Everyday use is as simple as connecting a laptop to the main port, a phone or tablet to the second port, and a set of earphones or a gamepad to the USB-A port. Pass-through charging also works, allowing you to keep the battery charged while your gadgets are being charged. The build quality feels strong given its weight, and the three-year guarantee is a nice touch, covering more territory than many other machines in the same price range.

It’s a little heavy to carry around in a jeans pocket, so it’s probably better in a backpack or jacket, and if you have many gadgets needing power at the same time, it’ll just balance the power between them. For someone who frequently needs to keep a laptop and a few smaller gadgets charged without an outlet, this unit’s size to power ratio makes it a very practical alternative.
