Anker 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 (Charging Base Not Included)

I absolutely love this thing. I keep it in my work bag and can charge my power-hungry laptop, Samsung tablet, and phone all at once. The star of the show here is the 140 watt output that can charge my laptop - no other charger I own can (on the go). This thing is fairly large and heavy, but it is extremely high quality and I think it'll last forever. Anker makes great stuff. Having the ability to see how many charges I can complete for each device given the current state of the device is awesome. The Bluetooth connection and app is surprisingly useful. I love that I can charge this thing using BOTH USB-C inputs to double the speed! Note that I did NOT buy the charging base as this was expensive enough as it was. Love this thing. I bought a case for it here on Amazon. It's amazing. Just make sure you have cables capable of the wattage you're looking to use this for. I bought a few especially for this device (one was a 240 watt cable, one was 100 watt, and the other was 65 watts). Anker sells plenty of great cables! One last note: This thing may be large but it cannot work miracles. It can charge my laptop not even once fully... However my laptop battery is massive. I can charge my phone 3-4 times and my tablet like 2-3 times I believe. If you're charging all three at once, like in my photo, it'll eat through the battery QUICKLY. But everything charges really quickly (my phone got Super Fast Charging 2.0, which is the quickest it can do).

I love this for traveling. It will charge my phone, laptop, and everything in between. USB-C and USB-A. The screen clearly tells you how much battery life is left and how close it is to being fully charged. I just hope I don't ever break the screen. Because of its capacity, it is not a quick charge. Just plug it in when you're going to bed and its ready to go in the morning. Yes, there are charge ports in every airport and just about every airplane now but with this, there's no concerns about getting hacked when you plug your phone in. This also works in travel coaches and on the trail. Its heavy but worth its weight to me. Finally, there have been times I've been told to take it out of my carry on for the x-ray but I've never had any other problems. For the frequent traveler, I highly recommend.

Peace of mind when you travel, camp remotely or have a power outage. This Anker Prime 250W Power Bank is a game-changer for staying charged. With 27,650mAh, it charged my laptop, phone, and tablet at the same time. AND then did it again for a second set of tech. Compact and TSA-approved (cuz who needs more stress at TSA security!). It’s perfect for travel, remote camping, or long workdays. Reliable, recharges fast, and feels substantial, without weighing a ton. Love this so much, I am considering buying a second for off grid working.

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.

UPDATE April 27, 2025: I wish I returned this, but I’m well beyond the 30 day return policy. This item has been my biggest regret. It literally exploded in my backpack the other day. Original review: I wanted to give it a full week of use before I wrote my review and I must say, I was disappointed after the first day. The power bank holds a charge for a long time. It doesn’t charge as fast as advertised. I does not charge your devices as many times as advertised. I have a MacBook Pro 14 and the full power bank can just barely charges it once and it does that quite slowly. I have an IPhone 14 Pro Max, charging my phone from 50% to 100% dropped the power bank to mid-high forties from 100% It charges slowly if you don’t have the charging station. I think when using both C-ports to charge it still took roughly two and a half hours to charge back to 100% and it was only on 50% It’s not worth the money. Good design. It gets warm but not too hot, I haven’t pushed it to extremes because I saw a video of someone just their iPhone and the power bank started to melt. It has some weight to it but just about what you’d expect. Because of the digital screen, I’d free dropping it or stuffing it in a backpack I plan to throw around. I like Anker, I’m disappointed in the amount of money I spent on this lackluster power bank that doesn’t perform nearly how they claim it will

My phone’s battery health is in the low 80s, and my will drop down to 50% or 40% remaining by the time I get home from work. I use this power bank to charge it while I’m sitting at the counter eating while watching a video, or while I’m playing a game in my recliner and not near an outlet. I’d rather not run a long cord from the wall to my chair so I use this power bank to charge my phone while I game, and I also use it to charge my controller. It’s been so useful. So far I’ve been using it for all of last week and it lasted the whole 7 days without needing a recharge. When it does need a recharge, it doesn’t take long at all. Normally it’ll take about 2hrs, but in the app you can set it to take longer to charge, to optimize its life, and that takes about 3 or 4hrs from 0 to 100. The screen tells you how much current is being put into the device and how much is being output, and the app tells you the same as well. I like this a lot more than I thought I would. It really shines when paired with the base station. I feel like the base station should have been included though. I noticed there was a bundle for the 20,000mah version and the base station, but not for the highest capacity 27,000mah. Would have been nice and a bit cheaper. Buying both together is expensive, but for a high quality power bank and the convenience of wireless dock charging and fast input and output, it’s really nice. My only complaint, if any, is lack of wireless charging built in for phones. This thing is the size of a brick and certainly weighs as much, why couldn’t they put a wireless charging spot below the screen mid way or something? Or on the back? A lot of devices are moving to wireless charging, for Anker’s most premium power bank, I feel like that should have been built into it. It’s not like it’s lacking the room for it. But I can get by with my MagSafe cord, it’s just a minor complaint if I had any at all. Oh, and the screen doesn’t rotate like the older model did. One thing I noticed is I can’t use the power bank while it is docked. I’m sure there’s a safety reason for that, but I’ve had one other power bank from another company that worked while it was charging. So it could charge a device such as a phone, while also receiving energy to charge the power bank itself. That power bank recently stopped working though. Still works, but the capacity has really gone down for only being 2yrs old. Maybe that’s why we can’t do that with Anker’s power bank? Idk, I just feel like it’s possible to do but maybe it has an effect on the longevity of the power bank. It’s not a big deal, the base has the same 3 usb ports on its side as the power bank has on top, but it was something I tried to do and noticed it wouldn’t work so I wanted to point that out. Overall though I think this is an excellent power bank and well worth the purchase, but maybe wait till you see a sale as it is certainly pricey

Okay so my review is rather lengthy. I bought my power bank back in January 2024. I was pretty happy with the quality of this consideration the price tag. Everything was working, fast charging, etc for a while. I kept my power bank mostly on the shelf for its entire life and brought it on a plane twice for my trip to Florida. As a lot of nerds like myself know, you're supposed to leave a battery in storage mode for long periods of time if you leave it unused. I left it like this for a lot of it's life as my emergency power bank. I had an issue the past week in January 2026 right outside of its warranty date. My power bank went unresponsive and claimed it was at 79% charge and would immediately die off of the charger. I knew something was wrong. I reset the battery and tried to revive it, but nothing. The BMS (Battery Management System) probably went bad or a few of the cells in my bank went bad. Keep in mind, at this point my battery has less than 10 cycles on the unit which is extremely low. My unit was 100% defective and I contacted Anker with my serial number and they sent a replacement. My replacement being "like-new" from Amazon lands them at the 4 star mark for their help. Would of been 5 if I got a new unit but my original power bank was a couple weeks out of their 2 year warranty so they didn't really need to give me anything. To conclude, make sure you use this thing from time to time before it craps the bed. But bravo to Anker for trying to correct this fault.

Purchased refurbished, arrived in like new condition, but at 0% charge. Plugged it in to charge with 2 cables (120watts). Got a little warm but no errors or temp warnings. Holds the charge too. I use it as an emergency battery for if the power goes out but I tested it using my analogue3d and ran fine for over an hour. The display has 2 modes, basic info and more info. It also has a neat clock feature while it's plugged in and two brightness settings. Bluetooth is always on or button activated, both modes need the screen on to connect. Anker app gives you even more data to monitor. The only downside is it's literally a brick. It weighs about the same as one and is almost the same size so it's kind of a pain to be portable. I don't have many USB c devices other than my phone but I'm sure it's compatible with a lot of stuff.

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

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

Prima secundair power station. Geschikt om ook grote laptop mee op te laden. Mooi display met laadgegevens per poort. Goed afgewerkt.

When placed on anker wireles charger after it reach 100% it start creating bizzing noise. Probably from internal electronic components. As soon you take if of the charger noise stop but it is quite loud,specialy when it is next to bed at night.
