Portable 10000mAh Charger
The INIU P55L is a slim 10000mAh lithium-polymer power bank that delivers up to 45W output through USB-C and USB-A ports. It suits travellers and daily commuters who need fast charging for phones, tablets and smaller accessories without carrying bulky equipment. The integrated USB-C cable doubles as a lanyard, so no separate cord is required for most devices.
Check Your Devices
Verify that your phone, tablet or accessory accepts USB-C or USB-A input and can use PD or QC fast-charging protocols for the highest speeds. The power bank operates at 12V and supports pass-through charging, letting you recharge the unit while it powers another device. Recharge time depends on the wall charger used — 15W takes about 3h, 27W about 1.7h — so ensure your adapter matches your speed needs. Airline rules allow 10000mAh units in carry-on luggage.
Built-In Cable & Safety
The non-detachable USB-C cable charges both the power bank and connected devices, then tucks into a storage slot for tidy transport. A battery indicator shows remaining capacity, and real-time temperature monitoring protects against overheating. Rated energy transfer is 60–70% of stated capacity, so a full 10000mAh bank typically provides 6000–7000mAh to devices — roughly 2.0 charges for a 3279mAh phone. INIU backs the unit with a 3-year care programme.

Questions about this item
Does the INIU P55L power bank include a built-in cable and what must I buy separately?
The unit ships with a built-in USB-C cable that also works as a lanyard and a user manual. A wall charger is not included and must be purchased separately.
How do I choose between the 45W output and the 10000mAh capacity for my device?
The 45W rating shows the maximum charging speed for phones such as iPhone 16 or Samsung S24. The 10000mAh capacity determines how many full charges you get — roughly two for a 3279mAh phone battery.
What does the 45W figure mean when I plug the power bank into my phone?
It means up to 45W output via USB-C, delivering 63% charge to an iPhone 16 in 25 minutes or 73% to a Samsung S24 Ultra in the same time.
