Customer Ratings & Reviews

I’ve used many portable chargers, but this one feels surprisingly small and lightweight for its large 20,000mAh capacity. The power is more than enough for home use, and it’s still light enough to carry comfortably when I’m out, making it convenient in both situations. The charging speed was faster than I expected, and the battery level indicator is clear and easy to read. The main reason I chose this product is because it has a built-in USB-C charging cable. It’s very convenient not having to carry around long charging cords every time. If you’re looking for a power bank with a reasonable capacity that works well both at home and on the go, this is an excellent choice.

I got this for my hunting pack! So far im extremely happy with it! Its smaller and alot lighter then my original one ive had for 8 years.Keeps my phone charged in the woods and ive used it 6 days in a row and i could charge my phone 6+ more days before the battery pack would be dead!

This has a huge battery capacity and fits well in the pocket. I am well pleased. I also dropped it from around 3 ft once already and still functions the same.

This is a great portable charger for on the go. It supports fast charging for my phone and I’m able to get multiple chargers out on one full charge. Would definitely recommend for anyone looking for a good portable charger with a great battery capacity.

This power bank is one of the best. It holds charge for a while even when charging two devices.

I recently utilized my monthly Best Buy+ membership privilege to acquire the INIU Pocket Power 20K Portable Power Bank. The price was $11.99 - a figure that, in retrospect, should have alerted me to the fact that I was not purchasing a product so much as I was purchasing a logistical tragedy. The package arrived yesterday. The exterior of the box featured a prominent warning label regarding the presence of a lithium-ion battery, as well as packing tape that loudly warned of its contents. This tape had been bisected by a sharp object, presumably to facilitate the removal of said battery by someone who was not me. The box also exhibited a structural tear, conveniently, happened to be right in line with where the item inside the box had been. Upon opening the container, I discovered the product packaging was present, but entirely hollow. The battery - the 20,000mAh of potential energy I had intended to use for my phone - was absent. It had been replaced by approximately 0.0 ounces of ambient atmosphere. I contacted customer support. The process involved navigating a digital labyrinth designed to discourage the weak of heart. I eventually reached a representative whose linguistic patterns suggested a high probability of being an algorithm masquerading as a human being. I explained that I had received a box of air. The "individual" informed me that because the item was on clearance, a replacement was impossible. This alone makes no sense - was the item on clearance, or did I use my membership perk? Apparently they are one and the same, and in this case it was a clearance item masquerading as a special deal. They issued a refund of my twelve dollars. I explained to the screen that I did not want my twelve dollars; I wanted the ability to charge my electronics while away from a wall outlet. The screen did not care. It is difficult to argue with a refund; it is the corporate equivalent of a shrug. My husband observed me staring into the empty box and asked if I had "tried turning it off and on again." I told him that one cannot reboot a void. He looked at the torn cardboard, nodded, and went to organize his tools. I am now in possession of a very small, very damaged cardboard box and twelve dollars of digital credit that feels like an insult to my time. It is a highly portable item, primarily because it does not exist. I would recommend this experience to anyone who finds their life currently suffers from an excess of functional electronics and a lack of frustration.

Very easy to use and charges my phone quickly. Great product for a great price!

The INIU Pocket Power 20K is compact yet powerful, making it perfect for travel or everyday use. The built-in USB-C cable is very convenient, and the 22.5W fast charging delivers reliable performance for both iPhone and Android devices. Battery life is impressive, and the design feels sturdy and high-quality. Highly recommended for anyone who needs dependable portable charging!

⭐️⭐️⭐️⭐️⭐️ 5/5 – Perfect Travel Companion! The INIU Pocket Power 20K Portable Power Bank has quickly become my go-to charger for every trip and daily outing. The built-in USB-C cable is a game changer — no more digging around for extra cords, and the fact that it works for both input and output is super convenient. With 20000mAh capacity, I can easily charge my phone multiple times before needing to recharge the bank itself. The 22.5W PD fast charging is impressive — my phone reaches a solid charge in a fraction of the time compared to other power banks I’ve used. I also love the sleek black design and pocket-friendly size. It feels sturdy and well-built, yet still lightweight enough to carry around without bulk. The LED display showing the exact battery percentage is a thoughtful touch. Whether for travel, long workdays, or emergencies, this power bank delivers on performance, convenience, and quality. Highly recommended for anyone who wants reliable portable charging!

Great portable power bank. The compact size is nice. Charging speed is quick and delivers multiple phone charges on one battery charge. Ability to connect more than one device at a time is a plus. It is heavier than expected which may be a consideration for some when traveling.

The battery was a life saver on our NY trip. It charged my IPhone 15 Pro Max from 20% > 80% in about 15-20 minutes. It charges quickly no matter where you are as long as you keep it connected and not use it for a moment. We charged our IPhones several times in between for 20% in order to keep running and we had at the end of the day around 40% left. The battery itself charges about AFAIR in about 1h fully. The battery is a bit on the heavy side but it doesn’t matter. The display is great as well and shows the remaining power. It’s worth the money.

Pretty good portable battery 20K is enough to charge my phone about 3 and half times (I have 23 Ultra). The built in cable helps alot I don't have to always carry a type C charger with me, I like how it is compact and give me the option to charge other devices with USB port and type C port. Only two things I dont like with battery is that it takes while to recharge the to 100% probably 2-3 hours. The battery has a safe guard where it will shut off its self after about 45 minutes of charging my phone which is alright, but just gotta remember to check connections.
