AnkerPrime 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)ClimatePartner certified

This has been a game-changing portable battery. I use it for travel, for working at cafes with no outlets, and for working outside (on the porch or at a park, although in the summer I’m the slightest bit worried about it overheating). Multiple times over the past year I’ve had coworkers ask to borrow it during conferences when their phone or laptop battery died, coming in clutch before important presentations or meetings, and they are so impressed with how attractive and useful it is they’ve told me they plan to buy their own when they get home. My wife also asks for me to pack it when we go on a trip together because of how convenient it is, especially with two USB-C ports. I’ve actually bought a second battery, which works well with the charging stand (I always have one charging or ready to go, while the other is in my bag). Feels durable without being overweight. The Bluetooth connection to the Anker app on my phone is surprisingly useful (for example, making sure it charges my laptop rather than the other way around) and my understanding is Bluetooth is only available on this larger of the two battery models.Would love to see Anker build out the Prime ecosystem even more, especially with other models of batteries that are compatible with the charging stand.

Sized to pass through TSA. While on the heavier side, this bank has not let me down. While traveling, I am able to keep my phone, action camera, digital camera, and my wife’s crap charged on long days.Pairing this up with the base makes a great combination(fast charging). While I do not use the functions, there is an app that adds interact with battery.If the mfg happens to read this. Making a base with more charging ports would knock the combo out the park. I typically leave the base home when traveling and carry an older charger having more ports to charge. I value number of devices I can charge from one source vs having the battery charged fast (when traveling). over the bases ability to charge the battery fast. Awesome product.

Pretty cool device. Bought it with the charging base. Works very well and holds a lot of charges for a pixel 9. The LCD display is is as clear and easy to understand. The Bluetooth features are plenty with lots of customization, sleep modes and safety features and also has a pager/beeper future. If you lose it. It can get heavy, so I recommend a carrying case. Got it on sale got it on sale, with the base station combined. It was under $145. I'm able to get full charges in handheld gaming PCs. I was also able to power or c car chargers with it. LCD display provides lots of information

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.

So I got this and was super excited to use it except, it wouldn't turn on. So I did the normal stuff and fiddled with it, pressed the button, held it, plugged it into a charger, plugged my phone into it, and a little power boot that read "Anker" kept slowly flashing over and over and nothing would happen. I was getting a little upset at this point, after spending over $150 you'd think the thing would turn on. Eventually I gave up and cooled down while watching videos on the same issue, and none of the solutions worked. I tried changing between 4 different cords, otterbox 60w, anker 240w, regular iPhone typeC-typeC, and a cheap skullcandy charger with usbA-usbC, still nothing. At this point I was getting ready to pack it back up and send it back. I Eventually decided to try the charger that came with it, plugged it in, and voilà, a green "100%" popped up and faster than red death I plugged my phone into it and it was working, stayed on, and I was able to connect via Bluetooth. No issues now but pretty ridiculous I had to do all that for give or take an hour just to turn it on. Anker, do better.
