Pocket-Sized 20000mAh Power Bank

The INIU P512 packs 20000mAh of lithium polymer capacity into a compact beige case measuring 2.8 by 4.1 by 1.2 inches and weighing 313.5 grams. It targets travellers and daily commuters who need multiple phone charges without carrying a bulky brick. The triple-port layout serves users who want to top up a phone, tablet and accessories from one unit.

22.5W Output and Recharge Limits

Maximum output reaches 22.5W through PD 3.0 and QC 4+ protocols, charging a phone to 75 per cent in 30 minutes and an iPad Pro to 34 per cent in the same window. Real-world delivery drops to 60-70 per cent of rated capacity, so expect 12000-14000mAh to devices. Full recharge takes 5.4 hours with a 20W charger or 6.6 hours with a 15W adapter via the USB-C input.

Triple-Port Build and Daily Use

Two USB-C ports and one USB-A port allow three devices to charge simultaneously, letting you share power with family or friends. An 18-layer SmartProtect system monitors temperature and reduces output to prevent overheating during extended sessions. The airline-compliant 20000mAh rating means it can travel in carry-on luggage without special approval.

Questions about this item

How do I choose between the USB-C and USB-A ports for my devices?

The power bank has two USB-C ports that support both input and output, plus one USB-A output. Use USB-C for fast charging newer phones and iPads, and USB-A for older accessories.

What does the 22.5W rating mean for real-world phone charging?

With PD 3.0 and QC 4+ support, it can charge a phone up to 75 percent in 30 minutes and an iPad Pro up to 34 percent in the same time.

How does the USB-C in/out port affect charging speed limits?

The USB-C port handles both input and output at up to 22.5W, so recharge time depends on your wall charger — 5.4 hours with a 20W adapter or 6.6 hours with a 15W adapter.
