Ultra Mini 10000mAh 45W Power Bank

The INIU P50 is a 10000mAh lithium-polymer power bank that delivers up to 45W output through two USB-C ports and one USB-A port. Its credit-card footprint and 1.44-ounce weight let it slide into a pocket or small purse for daily carry or travel.

Who it suits and who should look elsewhere

It suits commuters, students and travellers who need fast charging for phones, tablets or compact laptops without bulk. Buyers who require more than 10000mAh capacity, multiple simultaneous high-wattage loads, or wireless charging should consider a larger unit.

The spec that decides fit

The single decisive figure is the 45W maximum output: if your device charges at 45W or less via USB-C Power Delivery, this bank will fast-charge it; if your device needs more than 45W, it will not reach full speed.

Questions about this item

What comes in the box and do I need to buy a wall charger separately?

The power bank includes a detachable nylon-braided USB-C lanyard cable. A wall charger is not included; recharge via the USB-C port using a 15 W charger for about 2.7 hours or a 20 W charger for about 2 hours.

Should I choose the 10000 mAh model or a different capacity for my iPhone 14?

The 10000 mAh unit delivers roughly 6000–7000 mAh to devices. Using the 65 % efficiency rule, an iPhone 14 with a 3279 mAh battery gets about 2.0 full charges from one power-bank cycle.

What does the 45 W rating mean when I plug in a Samsung S26 Ultra or iPhone 17 Pro Max?

At 45 W the bank can charge a Samsung S26 Ultra from 20 % to 92 % or an iPhone 17 Pro Max to 75 % in 30 minutes, while TempGuard 2.0 keeps temperatures low.
