Prime Power Bank, 27,650mAh 3-Port 250W Portable Charger for Travel, TSA-Approved, Smart App, for MacBook Pro/Air, iPhone 16/15/14 Series, Samsung, Laptops, and More

This Anker power bank is seriously impressive. It charges my Dell XPS 16 and iPad M2 (6th gen) with no issues at all, even while using them. The power output is strong, and having three ports makes it easy to charge multiple devices at once. The battery capacity is huge, so I don’t have to worry about running out during travel or long days on campus. The app is a nice but not really useful because you can just use the screen on the power bank and it tells you the same information. The build quality is very solid. It’s a bit heavy, but that’s expected for something this powerful. Overall, it’s been super reliable and well worth it.

After months of using this power bank over camping trips and international flights, this is my go to power bank. Pros: Quality: The powerbank is of top quality in its ability to provide the required power continuously without any power drops. Charging speed: DEFINITELY buy a 140 W adapter along with it. When you are traveling or camping, a simple 38 minutes of charging gives you from 0 to 100% battery! I also use it in my international travels and a single stop at a cafe makes every device of mine charged thanks to this device. Battery life: This is at the limit of the airline limits, which is 100 Wh and this device is at 99 Wh. So this is the ultimate charging unit you can carry around while traveling abroad. It can charge my phone 3 to 4 times, and I can charge my MacBook 16" to use it throughout the day even if it had 0 charge at the beginning. Cons: These positive parts being said, here are some downsides. Size: It is quite big and heavy. So if you are going to use it on a daily basis and you do not have a backpack to carry this big boy around, then this item is not for you. Value for money: Well, I believe that you can still get a smaller product that will do the job for you with a more reasonable price. However, if you are traveling internationally or camping regularly, this is such a reliable one that I will be probably using this for years to come. Also check out Anker's 737 powerbank if you are concerned with the size. The charging speed is still really fast with that one as well.

I’ve been using this Anker power bank for a few weeks. It’s definitely got enough juice to charge my phone a few times, which is nice when I’m out all day. It’s heavier than smaller ones, but that’s expected with a battery this big. Build feels solid. It has a couple of ports, so I can charge my phone and headphones at the same time, which comes in handy. The little lights show how much battery is left, and the brightness is adjustable in the app. I also like the inclusion of the base has a couple extra outlets in as well for USBC and USB a charging. Charging it up is quick with the included dock, and it holds charge pretty well if you don’t use it right away. Overall, it’s reliable and gets the job done. Nothing flashy, just a solid power bank if you need extra capacity.

Even comparing to all the “high end” kickstarter/indiegogo graphene banks (uze bold/bold2, chargeasap flash 2.0/pro plus), and even with all its flaws (namely, the inaccurate battery SoC percentage meter, and no passthrough charging on this model - why?!), the Prime 250W is still the most up-to-date (protocol-wise) power bank on the market. It’s even got a slick app, albeit completely unnecessary. Since hardly anybody talks about on any reviews, reddit, forums, etc… about the cool dual port charging, I’ll talk about my experience here. After trying out a few different PD3.1 chargers, and making sure the cables were all good with my trusty KM003C, my best case maximum combined charge rate hit 166.5w. And that’s only when the battery’s display meter shows ~90%. I was hoping that it would get the full 170w beans (or more) because I generally get to its second highest rate of 166.2w at around 66%, which is at least somewhat positive that it can do the bulk of the charging at *nearly* the highest rate. Still… I can get single port charging at 141w, which is over advertised. Why can’t I get to 170w? Also, importantly, the unit definitely doesn’t heat up as quickly when charging via dual ports versus a single 140w port. Single port I’ve gotten to 40C, whereas dual port it’s 37-38C when it hits 100%. So I don’t think I’m hitting a thermal limit thats throttling me but I could be Wrong…. So maybe next time I’ll test my next dual port charge in the fridge. About the inaccurate battery percentage meter. It’s well reported by many. When the unit’s meter hits 100%, the real life battery charge is closer to 80%. I’m not going to talk about as to why that is, but you can speculate some logical reasons why Anker did this. Anyways, if you have an external meter, you will notice that the battery is still pulling a good amount of watts (100W+), which slowly trickles down to 0.1w. As I write this, it’s been 30 mins since I hit 100% and it’s still drawing a few. Although I hate the form factor that all the newer power banks are being manufactured as (i prefer the old style flat brick, not a thick brick), I think my 166+ watt dual port charging makes it the fastest charging usb bank on the market. All those graphene power banks designed years ago but released recently are all outdated. They claim they have amazing output with their SINGLE usb-c port having the ability to output 140W (if they even have that, most are still 100W at best) and their “ultra mega deluxe high speed” 100w input charging due to the efficient cooling of graphene (what a crock of s*). The Anker Prime 250W, with its plain ol’ lithium ion (I doubt it’s LiFePO4 otherwise they’d be raving about using those type of cells in the advertisement) can take a lot of input power which I just love. Although I haven’t tried any of the other latest cheap chinese branded PD3.1 banks to compare..z I read that some can even do dual port charging too but I digress. I wish they would make an actual graphene power bank and blow all other products out of the water. Have single port 240W EPR charging/output…. One can only hope. Maybe when TB5 and usb4v2gen3.2 3x3 comes out we’ll see a generational leap in tech with these power banks.

It is the beautiful "and" the beast! It is powerful enough to charge two laptops at the same time while being as compact and well-designed as it gets. It is pricey, I admit that, but nothing good comes for free!

I love this powerbank. It fast Charles your devices and it fast charges it self under 1h. Amazing powerbank.

Já tive alguns powerbanks, mas esse Anker Prime Power Bank é o supra sumo dos powerbanks portáteis. Compre e não irá se arrepender. Ele carrega meu celular completamente 4,5 vezes (iPhone 15 pro max).

Me gusto mucho se nota inmediatamente la calidad , y bueno cargo mis dos celulares 2 veces cada uno de 20% a 85% en más menos 35 min y me va diciendo que voltaje está enviando en cada equipo me gusto mucho

The product works perfect but you have to consider that you're not allowed to take it with you on a plane!' the Wh is wayy to high for that unfortunately. works great for daily use, I've used it for over 2 months now and no complaints, it gives me the freedom to work from anywhere for longer. I recommend buying a longer cable if you want to use your devices while charging, the included cable is of great quality, however it's really short and unsuitable for handling while in use.
