Compact 10000 mAh power bank

The INIU P50 is a 10000 mAh lithium-polymer power bank rated at 45 W output. It fits travellers and daily commuters who want several phone charges in a device roughly the size of an AirPods Pro case. The unit weighs 1.44 ounces and measures 3.29 by 2.09 by 1.0 inches.

USB-C and USB-A output limits

Two USB-C ports and one USB-A port share the 45 W maximum. A single device can draw the full 45 W, but simultaneous charging splits that budget across the ports. Recharging the bank itself requires a USB-C wall charger; a 15 W adapter takes 2.7 hours and a 20 W adapter takes 2 hours. Pass-through charging is supported.

Practical capacity and device examples

Stored energy is 10000 mAh at 12 V; typical conversion losses leave 6000–7000 mAh for connected gear. The supplier estimates about 2.0 full charges for a 3279 mAh phone. In 30 minutes a 45 W session can move a Galaxy S26 Ultra from 20 % to 92 % or an iPhone 17 Pro Max to 75 %. Larger laptops or extended multi-device sessions will exhaust the reserve faster.

Questions about this item

Should I pick the 10000mAh P50 or a larger capacity model?

The P50 delivers 10000mAh rated capacity, yielding roughly 6000–7000mAh to devices after conversion losses. That covers about two full charges for a 3279mAh phone or a solid top-up for tablets and ultraportables.

What does the 45W rating actually give me on a phone or laptop?

At 45W the bank can push a Galaxy S26 Ultra from 20% to 92% or an iPhone 17 Pro Max to 75% in 30 minutes, and it will fast-charge a MacBook Air or Steam Deck at near-full speed.

Which USB ports are on the P50 and what speeds do they cap at?

Two USB-C ports and one USB-A share the 45W total output. Recharging the bank itself takes 2 hours with a 20W charger or 2.7 hours at 15W, always via a USB-C port.
