Tired of waiting hours for your devices to charge? What if you could power up your MacBook and iPhone in minutes?
Need a power bank that can keep up with your demanding devices? I’ve put the INIU P63 25000mAh Power Bank to the test.
Today I’ll be reviewing the INIU P63 25000mAh Power Bank. This is my first time reviewing an INIU product, so let’s start with a brief introduction to the brand.
INIU has become a prominent name in mobile power, known for its emphasis on safety and performance.
Boasting a global community of over 38 million users, INIU strives to create charging products that are both efficient and dependable.
They demonstrate their commitment to quality through an impressive six-year warranty on their products.
The INIU P63 boasts a compact design for its 25,000mAh capacity. Thanks to INIU’s innovative TinyCell high-density battery technology and HyperStack design, it’s one of the smallest 100W power banks on the market, offering excellent portability without compromising on power.
For those who frequently need to charge multiple devices, the INIU P63 provides a compelling solution with its 110W maximum output, allowing for simultaneous high-speed charging.
Testing demonstrated that it can charge a MacBook Pro 14″ to 42% and an iPhone 15 to 65% in just 25 minutes.
The inclusion of a 100W USB-C port is a significant advantage, supporting both rapid device charging and quick replenishment of the power bank’s own battery in approximately 1.7 hours.
The power bank also supports Samsung Super Fast Charging 2.0, charging a Samsung S24 Ultra to 75% in 30 minutes.
Furthermore, the INIU P63 offers full-speed charging for the Steam Deck, ensuring uninterrupted gaming sessions.
So without further delay, lets get started with the review!
Packaging and Contents.
The INIU P63 25000mAh Power Bank comes packaged in a teal/white sleeved box which shows product images and printed specifications.
The box measures 14.0cm x 12.5cm x 3.8cm and weighs 473G.
Inside the box, you’ll find:
- One power bank
- One pouch
- One USB-C to USB-C cable
- One multi-lingual user guide
The supplied USB-C to USB-C cable measures approximately 62.0cm. The cable is robust and facilitates fast charging for my Google Pixel 8.
INIU P63 25000mAh Power Bank.
The INIU P63 25000mAh Power Bank measures approximately 110.2mm x 70.6mm x 35.7mm and weighs 397G.
INIU sent me a Yellow power bank, but the P63 comes in a variety of colours, which I’ll link below.
 Yellow |  Black |  Orange |  Red |  White |
I appreciate the vibrant yellow colour, which contrasts well with the black LCD screen (approximately 63.6mm x 42.7mm).
The screen is quite basic, displaying only the remaining battery percentage.
In my opinion, it’s oversized for the limited information it provides.
Ports.
The power bank features three ports on its top surface:
| Feature | Specification |
|---|---|
| Input (USB-C1) | 5V⎓3A, 9V⎓3A, 12V⎓3A, 15V⎓3A, 20V⎓3.25A (65W max) |
| Output (USB-C1) | 5V⎓3A, 9V⎓3A, 12V⎓3A, 15V⎓3A, 20V⎓5A (100W max) |
| Output (USB-C2) | 5V⎓3A, 9V⎓3A, 12V⎓3A, 15V⎓3A (45W max) |
| Output (USB-A) | 5V⎓3A, 9V⎓3A, 12V⎓1.5A (18W max) |
| Fast Charging Protocol | PD3.0, PD2.0, QC3.0, QC2.0, PPS, AFC, etc. |
For optimal recharging speed, use a power supply with an output of up to 65W.
The output capacity of the INIU P63 depends on which port(s) are in use.
The table below clarifies the output values for various port combinations:
| Combination | Maximum Output |
|---|---|
| OUT1 + OUT2 | 65W (max) + 45W (max) = 110W (max) |
| OUT1 + OUT3 | 65W (max) + 18W (max) = 83W (max) |
| OUT2 + OUT3 | 15W (Total) |
| OUT1 + OUT2 + OUT3 | 65W (max) + 15W (max) = 80W (max) |
A side button on the right-hand side of the power bank activates the remaining battery percentage display with a simple click.
A suggested improvement for INIU would be to add a trickle-charging mode for smaller devices such as smartwatches and earbuds.
This model does not offer Qi/Qi2 wireless charging.
The included mesh pouch is a welcome addition, providing convenient protection for the INIU P63.
Using the Power Bank.
I’m impressed. I don’t typically favour bulky power banks, but the INIU P63 has changed my perspective.
Despite its size, it fits comfortably in hand while providing a substantial 25,000mAh of portable power.
I’ve been using the INIU P63 with my Google Pixel 8, and it charges my phone quickly and reliably, activating the phone’s fast-charging function.
The INIU P63 also recharges quickly, taking approximately 1.7 hours to reach full capacity
