There's a moment most of us know too well: you're out for the day, your phone is at 12%, and the nearest outlet is nowhere in sight. The INIU Pocket Rocket P50 is designed for exactly that situation. This cute little charger is one of the smallest 10,000mAh power banks on the market and delivers more output than a lot of far larger and heavier competitors.
Most compact power banks make you choose – go small and sacrifice charging speed, or get real performance and carry the bulk. The P50 avoids that tradeoff using INIU's patented TinyCell 2.0 technology, which shrinks the battery cell footprint without cutting capacity. Measuring just 3.3 x 2.0 x 1.0 inches and weighing 5.6 oz, you get a charger that easily fits in a jacket pocket and has enough juice for roughly two full charges of an iPhone 16 or about 1.5 for a Samsung S24.
Fast charging and plenty of ports
The P50 comes with two USB-C ports and one USB-A, so you can charge multiple devices at once – useful if you're traveling with a phone, earbuds, and a smartwatch. With 45W fast charging, it can push an iPhone 16 to 63% in about 25 minutes. It also supports Samsung Super Fast Charging 2.0 and USB Power Delivery (PD).
So you don’t have to remember to bring an extra cable (which I often do), there's a detachable USB-C lanyard cable included.
On the safety side, INIU built in what it calls a Next-Level Thermal Management System, using the same grade of inductors found in NVIDIA hardware. That means the P50 runs cooler while charging than most competitors in its class, providing better safety and long-term battery health.
All INIU products are backed by 24/7 support (with a 2-hour response time) and a 3-year warranty. If your device is damaged due to an INIU product, they offer lifetime compensation.
