Surprising that a 20,000mAh power bank could be so small and light. I have other popular UGreen 25,000mAh power banks that are twice this size. I was a bit disappointed to discover that 45w is the maximum for charging the power bank. Also, the rather large black window devoted to LED readout functions only to show you the percentage of charge. The Various UGreen bricks will show this and also rate of charge, time until done charging, temp, and much more. From the picture I expected more than just a percent charge. Despite only being a 45W IN, the bank seems to charge rather quickly going from 50 to 60% while typing this. The output is either usb-C in and out at 65W or usb-A (18w) and usb-C (36w). This is perfect for my college bound daughter to throw in her back pack to use as backup for IPad, IPhone, and MacBook Air. That incredible if you consider the size and weight of the several bricks it replaces. I purchased her no brand 50,800 power bank which was much heavier so she never carried it. This she takes everywhere and her friends are the ones who benefit as well. One star off for not using the fast charge capabilities and for not taking advantage of the LED to show other info. Have ordered another myself, my wife, and 5 other Children. ( if you can’t beat them, out breed them).

It is really awesome, portable and not a damn brick like the rest of them, good grip and comes with a small fiber pouch with a cable charger cord for android, looks good has white digital numbers that show charging percentage, can at least almost charge two android phones (usually the other phone would be 60% before it drains) for an entire day until it runs out. While the primary phone is at 100%. I usually just plug it in while my cord charges the portable battery while the portable battery charges my phone, so two in one charging efficiency, decent. It functions well. It's durability is sturdy. I wouldn't recommend dropping it inside a toilet bowl for obvious reasons, this goes for all electronics.

I just purchased 2 of these power banks, both arrived about half charged (typical). When paired with a 45+ watt charger they recharge at about 1% per minute and consume exactly 45 watts while doing so. I used one of them to recharge my depleted Dell 13” laptop, and it worked fine, leaving 30% charge in the power bank. They also work fine with my low draw devices (ear buds, Bluetooth audio adapter etc) There doesn’t seem to be any low power shut down, which means you can deplete the power bank if connected to a device indefinitely.There is a button on the side to turn it on, and check charge level if needed.Keep in mind that while it does have a small footprint for its capabilities, it is still a bit chunky. It doesn’t defy Li-po physics.

Power bank is surely one of the most compact of the 20Ah class.Tested capacity @20V 1A is 68.2Wh, equivalent to 93% of the rated capacity (73Wh). Other voltages and currents not yet tested.Charging is very fast. 0-50% takes ~40 minutes with a 65W PD charger and after the first hour it charges to 76%.Power bank gets warm, but not hot. For longest life it is probably better to charge with a slower charger.Note: Only the outer USB-C port supports the full power/voltage and input charging. The center position USB-C port only supplies 5-12V and does not accept input charge.Display is a bluish white color. There is no green charge symbol as in the web images.

After my Nitecore 20,000mAh power bank failed (likely not its fault - it swelled after 1.5 years without use), I decided to purchase something different for my upcoming Scotland crossing next month (TGO Challenge). I bought the new *INIU Power Bank P62-E1, 20000mAh 65W Ultra Compact* from Amazon for $47. I received a fairly early unit - serial number 124. At first glance, it looks very promising: weight of 325 grams (on my home scale), 20,000mAh capacity.**Testing**To test the power bank, I used my Samsung S24 Ultra with its 5,000mAh battery. When I connected the phone to the OUT2 port, which allows charging at 36W, the phone displayed "Super Fast Charger." Indeed, it took about an hour and fifteen minutes to charge the phone from 15% to 100%.How much are those theoretical 20,000mAh worth in reality? According to simple calculations, I should be able to charge my phone 4 times (5,000×4=20,000). But that's all theoretical - because there are energy transfer losses and other efficiency issues.In practice, I was able to charge my phone 3 times through the 36W connection:* First time from 15% to 100% using 30% of the power bank (70% remaining)* Second time from 23% to 100% using 31% of the power bank (39% remaining)* Third time from 14% to 100% using 36% of the power bank (3% remaining)This means that in practical terms, we're talking about 2.6 full charges of 5,000mAh each - or a total of about 13,000mAh real-world capacity.As for charging the power bank itself - charging from 3% to 100% took about an hour and 15 minutes using a 45W charger.**What I Liked*** The weight (325 grams) is very similar to the Nitecore NB20000 (322 grams)* It has a battery percentage indicator - which is very useful* The corners aren't as sharp as the Nitecore, so I'm not worried about it tearing anything in my bag* Truth in advertising: they claim you can charge the Galaxy S24 with its 3,880mAh battery about 3.7 times, which suggests around 14,300mAh capacity - not far from the 13,000mAh I actually achieved on first use (it might improve slightly with continued use)**Bottom Line**An excellent alternative to the Nitecore NB20000.***EDIT***It actually states on the powerbank itself that the output capacity is 13,000mAh:"Output Capacity: 13000mAh/5V/65Wh (Typical energy loss accounted)"It is refreshingly honest - acknowledging that there's always some conversion loss when using a power bank. INIU transparency truly stands out.
