Anker Power Bank, 20,000mAh Travel Essential Portable Charger with Built-In USB-C Cable, 3-Port 87W Max Fast Charging Battery Pack, for MacBook, iPhone 16/15 Series, Samsung, Switch, and More

In "What Can I Bring", online TSA rules are saying (as of May 5, 2025) that only "Lithium batteries with 100 watt hours or less in a device" can be put in carry-on bags. Other restrictions do apply for checked bags.Annoyingly, most battery power banks are advertising mAh, which are not obvious to convert to Wh when the internal voltage of a device is unknown. And who is in position to explain to a TSA agent the compatibility of a power device?Also annoying: why are so many devices labeled with tiny characters and low contrast?To help other buyers, I took a photo of the back of this power bank. You can see it is capacity listed as 72Wh. That number and the logo are what you could show to let a zealous agent go through a TSA line.Besides the small characters, the only other thing annoying me is that the case is very slippery, like most smartphones. As I cannot buy a rubberized case for it, and as it does not come with a carrying pouch like my previous Anker model did, I fixed this slippery issue by stinking a couple of Velcro bans (the fabric part, not the hook part).Despite my small annoyance, this quality product still deserves my 5 stars rating.

Fast, sturdy, & trustworthy, as expected from Anker. Appreciating the attached USB-C cable for convenience & 87w charging capacity (which is currently charging my laptop, so...YAY!) I mistakenly thought it would be closer in size & weight to the Anker Nano, but it's much more in line with the larger brick chargers. Easily double the size & weight of the Nano, or roughly the same size as my Samsung 24Ultra (in its case) and double the thickness. It may be too much for those looking for a pocket-sized charging unit, but considering that it will also charge my laptop on a trip makes it a pretty neat little package for traveling.

Bought it for our trip to Japan on an average day we used it to charge both our phones it would still have around 60% charge left The clouded cable meant that even when I forgot the Long cable one day meant that we could just chuck one phone in the backpack and it would be charged within an hour and a half great product would recommend 10/10 also supports quick charge which is a huge plus.

Had it for several months now. The only complaint I have is it is way too bulky…. Other than that I love it… I used it with a anker cable, it works perfectly… but it tried with a anker 240w cable and it drain the battery faster. So I switch to a smaller watt anker cable and it last me at least a month or more…. But then I only used it when then power goes out or in those few times I may need it… (if I know a big storm is coming we charge everything up so we extra prepared…)

Purchased the Anker 20,000 mAh Power Bank to replace my old Power Bank for 2 reasons: 1) Has a built in USB-C charging cable and 2) Wanted a super fast Charging Bank. In general, very satisfied with the product but one disappointment (see below):PROS:1) Integrated USB-C charging cable very convenient. Cable that fits so snugly in its indented slot that it is completely flush with the remainder of the power bank. There is no chance that the cable will unravel or snag on objects that might result in damage to the cable2) The USB-C ports and the USB - C integrated cable are indeed super fast chargers. Subjectively they charge 2X faster than my other standard charging bricks.3) Love the ability to check the exact charge level of the bank( measured in % of full charge) by a simple push of a button at the top of the bank.4) Using a USB-C port, to charge up the bank to 100% capacity is surprising quick.5) Anker quality and reliability.6) Plenty of battery storage to recharge devices many times over.7) Trickle Charge Mode- I didn't even know what this was until I saw a video review of this battery bank. Apparently some battery banks cannot charge "low -powered" devices like earphones (battery bank will keep shutting off). This bank will also shut off UNLESS you activate "the trickle charge" mode by pressing the top button TWICE. Once you press the button twice a green light will appear on your battery status screen to acknowledge the above. Not all battery banks have a trickle charge mode. This one does.8) Retains Charge- I will charge battery to 100%. It sits in my drawer for greater than a *month and it still has the same 100% charge. *Addendum: Used the battery for several months now. Maintains charge of "100% " after 3 months of non-use.CONS:1) USB- A Port- Not a really fast charging port but not slow either. To me, seems like just a normal charge speed. No better or worse than a normal brick. This was a big disappointment in that this is advertised as a "max fast charge battery pack".2) Short integrated USB-C cable- only 6 1/2 " long. Very Short leash for charging your devices. Check length to see if this will work for your uses.SUMMARY : This is a great product from a reliable manufacturer that has attractive features ( integrated Cable, quantified charge level and has quick USB-C charge ports) but has normal quickness for the USB-A charge port. Again, this is my admittedly subjective opinion but hence, a 4 star rating. However, If all the devices you need to charge are USB C compatible, then this would be a 5 star product for you.Update: Used product for almost 8 months. It's been abused (dropped multiple times in my backpack) and still works like new. Impressed by retaining battery level after many months without use but just wish it was a little lighter.

I love Anker products. I needed a power bank for my laptop and tablets and I'm so happy I went with this purchase. Great packaging and the product itself feels and is working well so far. I love that it also displays the batter percentage.

I bought this for travel, and it is convenient, compact, and a unique color among all-black tech items.In terms of size, the power and speed of this power bank are fantastic. I bought it to charge my DELL laptop in a bind and primarily to charge my phone throughout the day. The attached cord is convenient and neatly tucks into the power bank. Never be without the charging cord.It is also very fast to charge the power bank, so you can always have it ready to go.

This is a great product. It's well built and sturdy. It charges up very quickly and I can charge my Android 3 times without having to recharge it. Love it!!
