Why Does It Feel Like a 'Not Sure 20,000mAh'?

Rated Capacity	20,000mAh
Understanding Capacity Loss	All the power banks could only supply 60%-70% battery to other devices, since around 30-40% of the capacity is lost in circuit heat and voltage conversions.(Actual Capacity ≈ 12000-14000mAh)
General Formula	(PowerBank Rated Capacity × 0.6) ÷ Device Battery Capacity ≈ Number of Charges eg. (20000mAh Powerbank × 0.6) ÷ 3279mAh iPhone14 battery ≈ 3.6 charges
Full Recharge Time	It depends on the power of the wall charger used: 18W fast charger - 6hrs; 5V/2A charger - 10 hrs; 5V/1A charger - 20 hrs

High-Capacity Power Bank That Delivers on Performance
Reviewed in the United States on August 8, 2025
Size: Classic SizeColor: BlackVerified Purchase

This INIU 20,000mAh portable charger has been an absolute powerhouse for extended trips and heavy device usage, providing enough capacity to charge my phone 4-5 times and still have juice left for my tablet or other devices. The 22.5W fast charging really makes a difference compared to slower power banks - my phone charges almost as quickly as it would from a wall outlet, which is incredibly convenient when you're on the go. I appreciate the clear digital display that shows exact battery percentage rather than vague LED indicators, making it easy to plan when I need to recharge the power bank itself. The build quality feels solid and premium, and despite the high capacity, it's still reasonably portable though definitely heavier than smaller power banks. While it's pricier than basic models and takes up more space in your bag, the combination of massive capacity, fast charging speeds, and reliable performance makes it perfect for travelers, outdoor enthusiasts, or anyone who needs serious backup power throughout long days.

The Best Portable Charger I’ve Ever Used, Just buy it!
Reviewed in the United States on July 3, 2025
Size: Classic SizeColor: BlackVerified Purchase
This 22.5W 20,000mAh power bank is easily the best portable charger I’ve ever owned. It’s become an essential part of my daily routine and travel kit. Honestly, if you're looking for a power bank for day trips or traveling and don't want to worry about running out of charge on a portable charger, this is the one to buy!
Charging ability:
With 20,000mAh, I get multiple full phone charges. For reference, I own a Samsung Galaxy S22 Ultra, and I can recharge my phone around 2-3 times from empty to full again with this charger, and possibly even more at times. I love how this charger supports fast charging for my phone because other portable chargers I've used in the past just charge my phone too slowly for me if I'm on the go. I also like the digital display as it makes it easy to know how much charge you have left on the device.
Size:
Another strong point about this device is its size. The size of this charger is the perfect size as it's not too big or bulky and roughly around the same size as my phone, just a bit taller in height. For the amount of power you are getting with this charger, I would expect it to be bigger, but it's still in a perfectly compact size that's easy enough to throw into a backpack. It might be a bit big for your pockets to carry, but it's definitely possible, as I've done it before, but it's not the comfiest, so I would suggest throwing it into a separate bag on the go instead. Another thing too is this thing is durable, I've dropped it and accidentally stepped on it a few times on accident and it's still for the most part intact and perfectly fine.
Flashlight feature:
I haven't used this feature much as I mainly use the device for charging, but it's definitely a nice option to have on the go and is really easy to use as well.

Can charge a Lenovo Thinkpad X1 2-1 Gen 8
Reviewed in the United States on September 4, 2025
Size: Mini SizeColor: BlackVerified Purchase
can charge a Lenovo Think Pad X1 2-in-1 Gen 8. I do not get warnings that the charger is insufficient. It charges the laptop relatively quickly.
Charges my iPhone and other devices.
compact form factor
included USB C to USB C cable is convenient and functions as a strap eliminating the need to carry a cable.

Con Minor - could recharge quicker.

I purchased this powerbank to replace a Omnicharge 9600, to recharge my laptop when needed. The Omnicharge powerbank's output was 60W. I was concerned that this unit's output was 45W, but it does charge my Lenovo Thinkpad X1 2-in-1.

I did not want to carry a larger heavier power bank and wanted a powerbank of this size to carry with me for when I am unexpectedly away from an outlet or without a charger and needed something to extend the battery. It is compact unlike larger heavier powerbanks. This fit the bill, it is there when I need it.

Size: Mini SizeColor: BlackVerified Purchase
Fantastic and super sturdy piece of equipment that has charge for days. My only quarrel is that it misses the mark for portability when I need to use it for marching on game days, as the portable charger weighs more than my entire phone. Thus making it a little inconvenient at times.

Replacing an Anker I bought in 2019. Much more powerful and charges my iPhone 15 Pro faster than my old one. Also holds a charge. I've gone days without charging the power pack, using it multiple times. The weight is the only thing I don't like about this charger, but that's all of them these days. 2 USB-C's, charge it up with USB-C, and comes with carrying cord that doubles as a USB-C cable. So far, it's my favorite of the half dozen I've owned in my lifetime, and I loved my old one.
