INIU P50 Mini Portable Charger, 10,000mAh 45W Power Bank with 3 Ports

At 3.29 x 2.09 x 1 inches, the INIU P50 is a compact power bank designed to take along in a small bag or pocket.

Its 10,000mAh capacity and stated 45W output make it a portable backup for phones and other compatible devices. Three ports—two USB-C and one USB-A—give you more than one connection option.

Choose it for everyday carry or travel when portability matters, a larger power bank may suit you better if you need more capacity between charges.

Highlights

The P50 combines a small form factor with a digital display, fast charging, and overcharge protection. It also includes a detachable USB-C cable that doubles as a carrying lanyard, so you can keep a cable close without packing it separately. The listed connections are two USB-C ports and one USB-A port, which can be useful when your devices use different cables.

The 10,000mAh rating describes the power bank’s capacity, not the amount delivered to a device. INIU estimates that around 6,000–7,000mAh may reach connected devices after conversion losses. The actual number of charges will depend on the device’s battery capacity and charging conditions. The product is described as flight-safe for carry-on use, check current airline rules before traveling.

How to use it

Recharge the power bank through its USB-C port. The manufacturer estimates about 2.7 hours with a 15W wall charger or 2 hours with a 20W charger, so recharge time depends on the adapter used. It also states that pass-through charging is supported, allowing the power bank and a connected device to charge at the same time.

For the fastest possible charging, connect a compatible device and cable to a suitable port. The 45W output is a stated maximum, not a promise that every phone or accessory will charge at that rate, device compatibility and charging requirements matter.

Tips for day-to-day use

The compact dimensions are useful for a commute, a concert, or a day out when a full-size battery pack would take up more room. The display can help you check the remaining charge before leaving, while the detachable cable-lanyard gives you a way to carry the unit or keep its cable with it. You’ll appreciate it if you want a small backup with multiple port types rather than a larger pack built around extra capacity.

Customer feedback is positive about the compact size, portability, and cable-lanyard design, and some buyers praise its charging performance. Feedback on charging speed and durability is mixed, however: some report quick charging and lasting use, while others describe charging or reliability problems. If you prioritize predictable performance over a pocketable size, that mixed feedback is worth weighing against a larger or simpler alternative.

Practical questions

Can it charge more than one type of device? It has USB-C and USB-A ports, and the product lists phones, tablets, watches, and other devices among compatible categories. Check your device’s charging requirements before relying on a specific charging rate.

How much usable capacity should I expect? INIU estimates that about 6,000–7,000mAh of the 10,000mAh rating may be delivered after conversion losses. The number of charges varies with the connected device.

Can I charge it while it charges a device? The manufacturer says pass-through charging is supported. The power bank itself recharges through USB-C.

Is it worth it?

The P50 makes sense if you want a compact 10,000mAh backup with a digital display, three ports, and a cable that can serve as a carrying strap. Its stated 45W output adds flexibility for compatible devices, but charging speed depends on the device and setup, and buyer feedback on performance and durability is not uniform. For a small everyday or travel companion, its format is the main draw, for longer stretches away from an outlet, consider whether a higher-capacity pack better fits your routine.
