Ready for Travel

The INIU P55L is a 10000mAh power bank designed for daily commuters and frequent flyers who need reliable backup power without carrying extra cables. Its integrated USB-C cord charges both your device and the bank itself, while doubling as a lanyard for quick attachment to a bag strap. A digital display shows remaining capacity at a glance, and a built-in flashlight adds utility in low-light situations.

Compact Build Quality

At 4.4 in by 2.7 in by .7 in, the lithium-polymer unit fits easily in a jacket pocket or small daypack. The slim profile is roughly a quarter smaller and noticeably lighter than comparable 10000mAh models, so it adds minimal bulk during extended outings. Two output ports — USB-C and USB-A — let you power a phone and a pair of earbuds simultaneously without hunting for adapters.

Check Before Ordering

Verify that your primary device accepts USB-C or USB-A charging up to 45W, as the bank delivers its maximum rate only over the USB-C port. Ensure you have a compatible wall charger to replenish the bank at 12 volts input, since no AC adapter is included. Buyers who need more than two simultaneous outputs or a higher total capacity should consider a larger unit.

Questions about this item

What does the 45W USB-C output actually cap at for an iPhone 16 or Samsung S24?

It delivers up to 45W and charges an iPhone 16 to 63% in 25 minutes, or a Samsung S24 Ultra to 73% in the same time.

Will the 4.4 in by 2.7 in by .7 in body fit in a small sling bag?

Yes, the slim 10000mAh design is 25% smaller and 15% lighter than similar capacities, so it slides easily into a tight pocket.

How do I recharge the power bank using the built-in cable, and what step gets missed?

Plug the integrated USB-C cable into any USB-C charger; the same cable charges your phone and the bank itself, but remember to press the power button to start trickle mode for small devices.
