INIU Carry P512 20000mAh 22.5W Power Bank – Market's Smallest 20000mAh Portable Charger, Airline Approved

I genuinely cannot believe this much capacity fits in something that slides into my jeans pocket. Charged my iPhone 15 three times over a weekend trip and still had juice left. The 22.5W output means it actually charges fast, not the trickle charge I expected. Best $18.50 I've spent on travel gear.

Took it through TSA twice with zero issues since it's airline approved and under 100Wh. Only wish it came with a wall plug included, but I already had a USB-C charger at home. Solid build quality.

Tiny, powerful, reliable. Exactly what I needed.

Bought this for my daughter who's at college all day and can't find outlets. She says it fits in her backpack's small pocket and charges her phone and earbuds. It does take a few hours to recharge the bank itself, but that's expected for 20,000mAh. The digital display showing remaining percentage is a nice touch that cheaper packs don't have.

Performance is genuinely good and the fast charging works as advertised with my Pixel 8. My only complaint is the weight — even though it's compact, 20,000mAh is 20,000mAh, and I notice it in my jacket pocket. If you're carrying a bag anyway, no issue at all.

I've carried a power bank daily for about six years and this is the best one yet. The form factor is genuinely remarkable — my old 20,000mAh pack was a brick, this is maybe half the volume. Charged my phone, my wife's phone, and a tablet on a single charge during a road trip. Low-current mode works great for my earbuds too. Can't recommend it enough.

My grandson helped me pick this because my phone kept dying at the doctor's office. He showed me how to use it once and now I keep it in my purse. Very simple, just plug in and it works. I like that it tells me how much power is left.

Unit arrived and would only hold about 40% of a full charge, and it got noticeably warm while charging my phone. Customer service was responsive and shipped a replacement quickly, and the replacement works fine, so I'll upgrade my rating eventually — but quality control clearly needs work.

Fits in the little side pocket of my carry-on, charges fast, and the USB-C in/out port means one less cable to pack. Got it on sale so the value is unbeatable. Would buy again.

Flew NYC to Tokyo with this and it kept my Switch and phone alive the whole way. Size is unreal for the capacity. Highly recommend for gamers who travel.
