INIUPower Bank, 20000mAh 65W Compact USB C Laptop Portable Charger, PD QC Fast Charging 3-Output Battery Pack, Travel Charger for Laptop MacBook iPad Tablet Steam Deck iPhone 16 15 Samsung S22

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.

This power bank is a BEAST!! INIU has proven, yet again, to be a high quality brand. I got this 20kmAh power bank to run my dash cam over parking mode. My 10kmAh, although it last a long time for my little extra phone and vape charges on the go, just couldn't cut it with the needed multiple hours of power delivery for a dash cam.After an 8 hour shift at work, this monster was at 95% (the LED display is super helpful), vs my other one dying around 4 hours of power delivery!! I am still in awe!! I am so glad I went with this power bank!!To also note, it does meet all specs as promised. It "super fast charges" my Samsung. It comes with, I believe, a one foot usb-c cable (its twice the length the 10kmAh ones come with). And a pouch for it. You can charge more than one device at a time. I charged my phone and galaxy tab at the same time with no issues (just remember, if you split wattage, charging will be a bit slower, as with any power source).As another reviewer noted, it does take a while to charge, about 1%/minute or if you're charging block and/or power source does not meet the power banks input specs for fastest charging (think a charging block that is a little older and will only "fast charge"), it charges at about 1% every 2.5 minutes or so.I will also add that this power bank is not small, and is a little heavy. However, it you're looking for this much power and with an LED display, its expected. The thickness looks to be about 3 of their 10ks horizontally stacked.Overall, I think this may be the best thing I've purchased in a long time. I am very happy with it!!

I love this cute little powerbank that's well-made. You have several options from a USB 18w power charge, to a 34w USBc power charge for those phones, or you can take it a step up and utilize the 65watts of pure horsepower to get your Ipad charged, or other devices that you need to power up quickly (be reasonable though since it's a smaller power bank).The quality of this unit is as good as it gets, and that's why I went to their website direct to purchase 3 other power banks as well for different purposes. I personally keep this specific powerbank (orange color which I love) at my side all the time to keep my Ray-Ban META Glasses charged up all the time without having to put them back in the case.This tiny power bank which isn't even that heavy, does the job well at the lower power of 34watts since 65 is a little overkill for the glasses (that I reserve for my laptop if needed). I think if you're going to invest in a power bank, get a power bank that is of high quality, high standards, looks good (not really important to many, but me yes) and is reliable (huge problem with your average power bank being of low quality and zero reliability).I'm so happy I purchased this, and will continue to support this great company as time goes on. Love their products, customer service and overall experience with mine and highly suggest YOU the possibly buyer to buy it, and try it for yourself! :D
