The INIU Pocket Rocket P50-E1 is the kind of gadget that makes me pick it up and ask how they fit everything in there. In my hand it is a small power bank with a display, several ports and a carrying loop that turns into the cable. ## The size is the first impression I open the box, take out the manual and hold the battery in my palm. It is presented as a 10,000mAh unit. That number is the stated capacity, rather than a measurement of how much energy I got into another device during this video. I talk about the thin battery and display design while looking at the product information, but the part I can demonstrate immediately is the package itself. It is compact enough to make the cable-storage question matter: carrying a tiny battery is less convenient if the cable is still a separate thing to remember. ## One loop, two jobs I pop the ends out and the lanyard becomes a USB-C-to-USB-C cable. After showing it, I plug the ends back in to form the loop again. I like having those two jobs handled by the same accessory. It is a similar idea to the cable on the [INIU P73 magnetic power bank](). That model adds the phone-attachment and stand arrangement; this video concentrates on the small Pocket Rocket body and its connections. ## Read the port ratings as ratings I identify two USB-C ports that can be used for input or output and a USB-A output. While reading the markings I point out a 45W USB-C rating and an 18W USB-A rating. This clip does not establish the charging speed of every port, a combined output limit or a timed result for a phone or handheld. I mention gaming devices as something the power rating makes me interested in trying, rather than showing a completed gaming-device charging test. My first impression is about the practical design: a small battery, an on-device display and a cable that goes straight back where it belongs. That is the feature I would remember when packing it. ## Links from the video **Affiliate disclosure:** These links may earn me a commission at no extra cost to you. - [INIU Pocket Rocket P50-E1 original Amazon link]() - [Playcast Pavilion original referral link]() Links and offers are from the video description.
