Brilliant
Charges my phone very quickly. Easy to recharge and very useful. I just wish it had a larger battery life. It’s very small which makes it easy to take with you but it would be great if it was slimmer and not so bulky but this is just a personal preference and doesn’t affect the use or performance. It’s great quality and very well built. The keyring makes it easy to attach to items such as a bag. The percentage light on the top are also a great addition to the design so you know how much charge you have left.

I Don’t Go Anywhere Without It.
This is a fantastic purchase and it’s incredibly versatile, it’s sturdy and hangs off my keys, so I’m never caught out with a dead battery.The design, battery life and weight are all top-notch. Only area for improvement is the USB ports. I’m sure, offering a standard USB port would allow those with Lightning cables for example, to use it too. This would likely boost sales and justify the cost. I’m fortunate that all my devices are USB-C, so I appreciate the small cable tucked neatly into the side for charging my iPhone 17 if needed.A tip for anyone with a bulky protective type watch strap: you might need to lie your watch face down and place the charger on top, remembering to press the small power button. My strap is Very Chunky so this might not be an issue for everyone anyway.Overall, I’d give it 5 stars and highly recommend it to anyone with an iWatch or iPhone.

Great for anyone who wants a simple, portable charging solution.
I got this INIU 5000mAh power bank for travel, and it’s honestly become one of those things I don’t leave the house without. It’s small enough to fit in my palm and fits easily into my handbag, which makes it super convenient when I’m out all day. The build feels solid, not flimsy, and I really like having the built-in USB-C cable so I’m not constantly digging around for wires. It’s especially handy during commutes or long days out when you just need a quick top-up.What really impressed me is how fast it charges my Apple Watch—it’s noticeably quicker than other portable chargers I’ve tried. I can get a full charge in just over an hour, which is perfect when I’m in a rush. The 5000mAh capacity is more than enough for keeping my watch going for days, and it can also give my phone a decent boost when needed. Being able to charge multiple devices at once is a big plus too. The only negative is to charge my son’s iPhone 14 Pro I had to use a separate lightning lead but was still easy to do.Overall, it’s compact, reliable, and genuinely useful—great for anyone who wants a simple, portable charging solution.

Excellent for me.
This was an impulse buy for me. I have had a similar but larger item that worked ok, but this is much better. My apple ultra watch is set in a fairly robust and bulky protective watch case. So chargers similar to this will not allow my watch to sit flat enough (mainly because of the straps). This one came out of the box at 50% charge, so I plugged it in to charge up. It reached full charge very quickly, I then put my watch on it to top up, for transparency, because of the strap I always set the strap to its smallest circumference, and then insert the charger, and place the watch face down on a flat surface, thus keeping the charging plate in full contact with the charger. This is purely because of the watch strap resistance. This charger actually charged my watch up to 100% very quickly, whereas others for some reason only charge up to 80%. This one is significantly smaller than others, charges up both itself and the watch much quicker than any others I have used. Remember it will also charge another piece of tech up via its built in USB C cable at the same time, whilst being on charge itself and charging your watch. In my opinion, a great compact efficient smaller then average charger, with more efficient charging options than many others, ideal for me while travelling, certainly recommend.

Great
Great little charger, little bit heavy to fit on a keychain but does the job and very fast charging speed.

Compact, handy and great for on the go
Really impressed with this little power bank. It’s compact and lightweight so easy to carry around in a pocket or bag without feeling bulky.Perfect for quick top-ups when you’re out and about. I’ve used it a few times and it gives a decent boost to my phone when needed.Build quality feels solid and it’s simple to use, just plug in and go. Ideal as a backup charger rather than something for multiple full charges due to the size.Great for travel, days out or just keeping in your bag for emergencies

Great little gadget
Great handy little charger. This is the second I have bought. A relative is in hospital and charging their watch was an issue when confined to bed.

Attachment loop is a weak point
We bought this as it had a loop that could be used to attach to a key chain, but the loop soon frays and breaks.

The INIU Pocket Size 5000mAh Power Bank (20W PD Fast Charging) is not just a charger—it’s a tiny emergency power plant that somehow fits on your keychain and laughs at low-battery anxiety.First of all, the size is absurd. This thing is shockingly small, yet it delivers real 20W PD fast charging that actually means business. Plug it into an iPhone 17 / 16 / 15 / Air and you can feel the power flow. No trickle charging. No “maybe it’ll help.” This is legit, fast, confidence-restoring juice. 😤⚡The built-in USB-C cable is genius. No cables to forget, no digging through bags—just flip it out and you’re charging. Clean. Elegant. Prepared. And then INIU casually adds a built-in Apple Watch charger like it’s no big deal. iPhone dying? Watch about to tap out? Handled. One device, two lifesavers. 🕒📱Being keychain-ready turns this into everyday carry perfection. Clip it on and forget about it—until the exact moment you need it, when it suddenly becomes the hero of the group. Airport delays. Long days. Emergency situations. This thing shows up clutch.Despite the compact size, the 5000mAh capacity is perfectly tuned for real life—enough to rescue a phone or keep your Apple Watch Ultra / Series 11 / 10 / 9 / 8 / 7 / SE alive when it matters most.⭐️⭐️⭐️⭐️⭐️
