Power banks are extremely useful gadgets that come in handy at the most crucial times and take away the panic of a low‑battery notification. Most have a standard “grey slab” look and, depending on capacity, can get quite big and heavy. INIU aims to change that without compromising on features.

Their standout product, the Pocket Rocket P50, is designed for busy urban professionals, students, and creatives who need reliable charging without the bulk. It looks good, seamlessly fits into daily life, and boasts impressive capacity for its size. Here’s what you need to know.

10,000 mAh capacity in a compact form factor

The Pocket Rocket P50’s main feature is its 10,000 mAh capacity with 45 W output, all packed into a device that weighs just 160 g. For comparison, a chocolate bar is about 100 g and a pack of biscuits is around 200 g—you probably won’t even notice it in your pocket.

This compact size is thanks to INIU’s patented TinyCell Pro battery technology, which makes the P50 about 45 % smaller than a typical 10,000 mAh power bank. By combining multi‑tab battery cells with a precise stacking method called HyperStack, the P50 ends up 25 % smaller and 15 % lighter than most similar products.

• Dimensions: ~8.3 × 5.2 × 2.6 cm
• Six color options: Moonlit Vanilla, Blossom Pink, Glacier Blue, Oasis Mint, Twilight Purple, Bonfire Black

These color options are uncommon for power banks; INIU wants the P50 to be something you keep on your desk, not hidden away in a bag.

45 W charging speed means you aren’t waiting around

The P50 delivers a maximum output of 45 W, roughly twice the power of most affordable power banks that top out around 22.5 W. With this speed you can:

• Charge an iPhone 16 from 0 % to 63 % in about 25 minutes
• Charge a Samsung Galaxy S25 Ultra to 73 % in the same time

The device supports Power Delivery (PD), Qualcomm Quick Charge (QC), and Samsung Super Fast Charging 2.0, ensuring compatibility with most flagship smartphones.

The 10,000 mAh battery provides 1.5–2 full charges for typical smartphones and even some smaller tablets. It features three ports—two USB‑C and one USB‑A—so multiple devices can be charged simultaneously without an adapter. A small 0.5 mm LED display shows the remaining battery level, remaining thin yet easy to read.

Solid build quality and plenty of safety features

Cheap power banks often overheat or wear out quickly. INIU addresses these issues with a multi‑layered thermal management system that includes:

• Temp‑Guard battery cell
• NVIDIA‑grade inductor
• Heat‑dissipating display panel

Tests show the P50 stays cooler than competing models during heavy use, improving safety for both the charger and connected devices.

An E‑Marker chip in the USB‑C connection negotiates safe power levels, preventing over‑loading and potential damage to expensive phones.

Durability highlights

• USB connectors tested for 10,000 powered insertions (twice the industry standard)
• Battery cycle tests performed at maximum charge and discharge rates

A detachable USB‑C lanyard cable is included, keeping a cable handy for travel.
