INIUPortable Charger, Ultra Small 10000mAh 45W PD Power Bank, USB C in&Out Fast Charging Battery Pack, External Phone Powerbank Compatible with iPhone 15 14 13 12 Samsung S22, Ugreen

You know I had seen this companies power blocks on Amazon for the last year and seriously considered the purchase at least a couple of times. So what held me back? Well I am embarrassed to share "the why"! The fact is after doing my usual comparisons and reading others reviews both on and off of Amazon, I felt that the product line seemed too inexpensive for what they offered! I can't believe I just committed that in writing! But now that I have one I feel the importance of issuing the correction that never was. I received this wonderful little gem of a power block and as it arrived with a 45% charge, plugged it in and 45 minutes later the LED read 100%. I plugged it into my iPhone 15 and after fully charging my (2% remaining) battery, my power block still had 35% left. Perfect for my purpose of an emergency backup. I have now used the unit to charge my phone at least five times and my laptop once. No, it doesn't stand on its own merit when compared to similar units in the same catergory... IT EXCEEDS THEM ALL. AT LEAST OF THE EIGHT OTHERS I HAVE TRIED in the last few years! My favorite feature has to be its size. This is without a doubt the most lightweight (in it's category) pocketable fun power block I've ever used! I just placed my order for two more in this size but upgraded to both a higher wattage of 100 as well as a 25000 battery in order to use it as a primary laptop unit every day. So at this great price take advantage of a sale and you too may be pleasantly surprised.

I absolutely love this thing! I am kind of addicted to my phone, and so I have used a lot of portable battery packs my day. This is one of my top favorites. It is small and light enough to carry around easily in even a relatively small purse. I love that it has the cable for charging built right in! It makes it look like it's just a keychain, but it's actually a charging cable. It also seems really sturdy like it's not going to accidentally fall off the cable loop. And given how small it is, it also seems pretty powerful. I tested it out for 10 minutes without using my phone during that time and my phone's charge went up 10% while the charge on the battery pack only dropped 4%. This is for a Google pixel 8A. The only downside to me is that it doesn't come with a wall block to charge it with a USBC, but I imagine everyone has a few of those lying around anyway, so that's not really a downside. It also did not really warm up noticeably during the 10 minutes that it was charging, which has been an issue for me with some battery packs.

I own several power banks from INIU, and this one has quickly become one of my favorites. It’s incredibly compact and lightweight, which makes it perfect for daily carry or travel. Despite the small size, the 45W output is impressive, and I’ve noticed it charges faster than some of my larger INIU models.The detachable USB-C lanyard cable is a thoughtful touch—super convenient when you're on the go and don’t want to dig around for cables.The only reason I’m giving it 4 stars instead of 5 is that the surface is a bit slippery, and I worry I might drop it if I’m not careful. A little more grip would’ve made it perfect.Still, the combination of portability, charging speed, and practical features makes this a great power bank.

I ordered this because of its tiny size, and I honestly thought there was no way this could have the stated capacity in such a small package.I did some quick quantitative testing to see what the actual capacity was.The first test was to charge it to 100%, and I ran it down to empty (shutdown) using my DC load and a USB-C trigger board. I set the trigger board to 12V and set the load to draw 2.00A, and let this run. This ran for about 1 hour and 15 minutes, and it drew 2518 mAh (30.5 Wh) from the battery.I tried again (after charging back to 100%), but this time set the trigger for 5V, and set the load to 2.00A. This time, it ran for 3 hours and 4 minutes, and drew 6137 mAh (31.4 Wh).I included a photo of the back of the battery that shows the specs:Battery Capacity: 10000mAh/36Wh/3.6VOutput Capacity: 6200mAh/5V/31.5WhBased on these specs - the battery output capacity was nearly exactly matched when I did the 5V rundown test! So I stand corrected on my prediction that it would be an underwhelming performance.

I've used INIU power banks for a while and have always been impressed by their quality and reliability. My older power banks are still working well. What truly sets this power bank apart is the size. I was genuinely surprised by how compact it is when I saw it in person. Everyone who has seen it has made a comment about the size. One person even thought it was a toy!The design includes a built-in USB-C cable that doubles as a lanyard, which is a clever way to keep the cable with the device. However, I would be a little concerned about the cable coming loose if you actually used it as a lanyard. To me, that is the only feature that feels a bit gimmicky.When it comes to performance, this power bank charges my iPhone quickly and showed a 45W charging speed when I connected it to my MacBook Pro. I cannot objectively verify the 10,000 mAh capacity, but has charged my devices enough to say that it's close to that capacity.I got this as part of the Amazon Vine program, but overall, I really like this power bank and am considering purchasing another one.
