If you’ve spent the last few years carrying around a brick of a power bank “just in case,” INIU wants to steal that habit. The company quietly launched the Pocket Rocket P50 — a pastel-hued, macaron-sized 10,000mAh battery that’s being billed as the world’s smallest 10,000mAh power bank. It’s small enough to disappear into a jeans pocket, but loud enough on spec sheets to make you do a double-take.

The headline numbers are what INIU expects will sell: the P50 measures about 3.3 × 2 × 1 inches (8.3 × 5.2 × 2.6 cm) and weighs ~160g (5.6 oz) — roughly “45% smaller” than what the brand calls a standard 10,000mAh brick. That tiny footprint is the product of denser cell layout and what INIU markets as its TinyCell Pro battery architecture, plus tight thermal and component packing. On the outside, you get a small digital display for percentage readout, a detachable lanyard that doubles as a USB-C to USB-C cable, and six pastel color options that the company leans on heavily in its advertising.

Don’t be fooled by the cute exterior: the P50 is rated for 45W max output, and it carries three ports — two USB-C and one USB-A — so INIU says you can charge up to three devices at once. The unit supports the usual fast-charging standards (PD, QC and Samsung’s PPS/Super Fast Charging), and INIU claims it can handle both input and output at high speed when used with the right cable and adapter. Those features are what let it pitch MacBooks, tablets and flagship phones as reasonable targets for a “pocket” power bank.

INIU’s marketing copy is specific: the P50 can allegedly charge an iPhone 16 from 0 to 100 twice, refill an AirPods Pro case more than 11 times, or top up a Samsung Galaxy S24 about 1.5 times on a single charge. The brand also says the power bank can push a phone from dead to roughly 70–75% in about 25 minutes under ideal conditions. Those are useful shorthand numbers for shoppers, but they come with the usual caveats — real-world results depend on phone model, screen on/off state, cable quality, ambient temperature and whether you’re charging multiple devices at once.

INIU says the P50 includes 18 layers of safety protection — protections for overheating, overcurrent, short circuit and the like — and highlights a “multi-tab” cell architecture and thermal layers as part of its TinyCell Pro design. Those kinds of promises are good to see; they’re fairly standard at this point for reputable accessory makers. Still, buyers should look for third-party certifications (CE, FCC, UN38.3 for air travel) and early hands-on reviews before assuming lab-grade reliability.

The P50 is priced aggressively: INIU lists it around $32.99–$38.99 depending on promotions and region, and it’s already showing up on Amazon and INIU’s official store with intermittent discounts.

If you value minimal bulk and want genuine fast-charge capability in a small package, the P50 is aimed squarely at commuters, students and travelers who value portability over absolute top-end capacity. For people who need many consecutive charges (multi-day camping, back-to-back flights without recharging) a larger high-capacity brick remains the smarter choice. Likewise, power-user laptop folk who want multiple MacBook refills will still prefer bigger packs — but for an emergency MacBook/Air boost or to keep a phone going all day, the P50 is a tempting compromise. Coverage for multiple devices at once is convenient, but remember that simultaneous charging usually divides the available wattage.

INIU’s Pocket Rocket P50 is one of those products that feels like progress: shrinking power storage without neutering useful output. The specs suggest it will please people who hate pockets full of tech, and the price makes it easy to justify as a backup for daily carry. The main reservations are the same ones you should have with any new power accessory: marketing claims need to be validated by third-party testing, and real-world performance varies by use case. If you want something that’s genuinely pocketable, pretty, and fast — and you’re comfortable waiting for independent reviews before deciding — the P50 is worth a close look.
