I’m constantly switching things out of my backpack, depending on what I’m doing on a given day. However, the one accessory that has remained a constant has been a portable power bank. Not just any ordinary battery pack, though, but one that offers the utility I crave to power everything I carry with me.

That’s why I’ve been testing the Iniu Pocket Rocket P50, which is touted as the world’s smallest 10,000 mAh 45W fast-charging power bank. I didn’t think the perfect power bank existed until I checked out the Pocket Rocket P50, and now, it’s ruined everything else I’ve tried. I honestly think it’s the smartest design power bank I’ve used, plus it’s under $33.

Part of the reason why I think it’s the perfect power bank is how incredibly compact it is. Previous 10,000 mAh power banks I’ve owned were larger and way heavier than any of my phones, but this one’s a fraction of the size at about 3.3-inches long and 2.09-inches wide.

Even though Iniu likes to draw comparisons to the AirPods Pro 2 charging case, it’s actually a little bit larger in real life. Still, for a 10,000 mAh power bank, it’s substantially more compact than anything else I’ve used.

But what’s even more fascinating is that it offers up to 45W power output, which is enough to power my HP Omnibook 5 — so that’s saying a lot. Power banks are expected to recharge smaller gadgets like phones, wearables, and wireless earbuds, but they don’t typically have the power to charge larger electronics.

There’s also two USB-C and one USB-A ports, so I don’t need to bring along an adapter to charge some of my older gadgets still clinging to USB-A charging.

It feels like it should be at a higher premium given its compact and smart design.

Another reason why I think it has one of the smartest designs I’ve seen ever is because it also includes a detachable lanyard cable.

Other power banks sometimes have an integrated charging cable, but my problem with that is that if the cable goes bad, you’re stuck with it — whereas the one in the Iniu Pocket Rocket P50 is a separate cable.

The only thing missing is a wireless charging pad, but I’m willing to overlook it because of its fast 45W wired charging speed.

Honestly, I can’t get over the fact that it costs under $33 because it feels like it should be at a higher premium given its compact and smart design.
