Anker Prime 27,650mAh Power Bank (250W), 3-Port Portable Charger, Smart App, Compatible with iPhone 16/15/14/13 Series, Samsung, Dell, AirPods, and More (Charging Base Not Included)

The build quality feels premium and durable, and it packs a ton of power. It can easily charge laptops even high capacity ones like my 80Wh laptop battery and still have some power left over. It also supports fast charging for phones. The 250W output handles multiple devices easily. Overall, this is one of the best and most reliable power banks I’ve used. its a pretty heavy one obviously but not bad for carrying around in a backpack. The size is also compact for the amount of power this thing can put out.

​I've been using portable chargers for years, but the Anker Prime 27,650mAh is the first one that genuinely changed how I travel. This isn't just a phone top-up; this is a full-blown mobile power station, and it delivers on every promise. ​The Power and Capacity: ​The 250W output is where this thing truly shines. It means I can charge my MacBook Pro and my phone simultaneously at nearly full speed, which is something very few power banks can do. If you work from a laptop or use a high-powered tablet, this is non-negotiable. The massive 27,650mAh capacity means I get multiple charges for my phone and a full charge (or more) for my laptop. It basically bought me an extra half-day of uninterrupted work during a 10-hour flight delay. ​Design & Display: ​It's a chunky brick—let's be real—but the build quality is flawless. The best feature is the smart digital display. Seeing the exact percentage remaining, the total power output, and the estimated recharge time is incredibly useful and removes all the guesswork that comes with standard four-LED power banks. ​The Only Downsides (Keep in mind): ​Weight: It’s heavy. You won't forget it's in your backpack. ​The Base: It doesn't come with the charging base, which is an extra purchase. While not essential, the convenience of just dropping it onto a dock to recharge would be nice. ​Helpful Tips for Getting the Most Out of It ​Based on my usage, here are a few things you should know to maximize this power bank's potential: ​1. The Airline Golden Rule ​This is the single most important tip for this specific model: It is 99.3 Watt-hours (Wh). The maximum capacity allowed in carry-on luggage by most airlines is 100Wh. This bank sits just under that limit, making it perfectly fine for air travel. Keep it in your carry-on luggage (never check power banks!), and you'll have portable power for long flights. ​2. Fast Charging In, Fast Charging Out ​To recharge the 27,650mAh capacity quickly, you must use a high-powered charger. If you try to charge it with an old 15W phone brick, it will take half a day. Use a dedicated 100W+ USB-C wall charger (Anker makes great ones) to refill the bank in just a couple of hours. It’s worth the investment. ​3. Check the App for Efficiency ​The Smart App connectivity seems like a gimmick, but it's actually great for checking battery health and optimizing charge flow. If you find your devices aren't charging as fast as they should, the app can often give you better insight into which port is delivering what wattage, allowing you to quickly troubleshoot. ​Final Verdict ​If you only need to charge your AirPods or phone once, this is overkill. But if you have a laptop, a tablet, or multiple high-draw devices, and you spend any amount of time away from a wall socket, the Anker Prime 27,650mAh is the best in class. It’s a serious investment that completely eliminates battery anxiety.

One powerful powerbank and definitely worth every penny. I charged it 100% roughly 8 months later it held it's charge and still 100% charge. App brilliant and all the usb works perfectly.. I can charge my phone x6 from 0% battery.. definitely perfect for holidays and work etc. take 12 hours to charge so don't expect it to charge quickly.

Brilliant bit of kit. I use the power bank when I'm out flying my drones, so i can keep charged out on the go. Since ive been using it its never ran out on me while ive been out, the capacity is great. Both the power bank and dock have excellent build quality and feel like they could take a beating. Anker have also included an app that helps you monitor your charging and also gives a few extra features like power saving modes where the device will charge at a slower rate between low usage times to improve battery life. The dock is a fantastic addition to have on your desk. (where mine lives) its multi function of both a charger for your power bank but also the addition of two USBC ports and a single USB port give it useful functionality besides just doing one or the other. Unfortunately like many other manufacturers they have decided to add that textured feel design along the sides of the power bank. meaning there are many small valleys and peaks where dust and dirt is attracted and then accumulates, if you work or take the device to dirty environments this can become frustrating as its not often the easiest to clean. not sure why manufacturers are obsessed with using this design. its not a big issue but i know it frustrates me so maybe it does others.

This powerbank is heavy and well made with a large capacity and very fast charging for laptops, phones or portable games consoles like the steamdeck Where it falls short on expectation is the accuracy of the ‘Time remaining’ when powering devices that consume under 1w of electricity. The mobile application is a nice feature that allows you to toggle On Volts and Amps as well as watts for all the power nerds out there.

Brilliant piece of kit from Anker. Design, functionality and build quality is excellent. A bit weighty, but forgivable for such a versatile power bank. It charged my Surface Book 2 through a small adaptor with no hassle whatsoever, something I was not able to do with my other units. Now I only need this and my GaN wall charger instead of different charging bricks. Recharge speed from a normal USB-c charger or wall socket is slow, which is expected but with a GaN charger at 100w it was a rapid process. This is a premium device and, in my opinion, well worth the money. A GaN 100w charger would be a worthwhile investment, along with 100w capable cables, which would complement this outstanding piece of kit.

This power bank is an absolute beast! I've had the Anker Prime 27,650mAh for almost a year now, and it's become my trusty companion on every trip and outing. Here's what I love about it: * Ultra-Fast Charging: With two USB-C ports and a USB-A port, I can juice up my PS Portal, phone, Switch, and other devices simultaneously at lightning speed. No more fighting over charging cables! * Massive Capacity: This thing is a tank! The 27,650mAh capacity means I can go days without needing to recharge the power bank itself. Perfect for long journeys or festivals. * Durable Build: It's a bit bulky, but that's because it's built like a tank. I've accidentally dropped it a few times, and it's still going strong without a scratch. * Anker Charging Base (a MUST BUY!): Grab the Anker charging base for this – it charges the power bank back up insanely fast. Seriously, it's a game-changer. * Bluetooth and App Connectivity: The Anker app is surprisingly useful. You can monitor battery levels, customize charging settings, and even update the firmware (which I highly recommend, as it improved my battery life). A couple of minor niggles: * Fingerprint Magnet: The glossy front panel attracts fingerprints like crazy. But hey, that's a small price to pay for such an awesome power bank. Overall, the Anker Prime 27,650mAh is an absolute winner. If you're looking for a reliable, powerful, and feature-packed portable charger, look no further. You won't be disappointed!

Fast charging and discharging, it easily powers my MacBook (65 watts) , S23 Ultra (45 watts) and iPhone 15 Pro (29 watts) at full speed at the same time without getting anywhere near the insane 250 watts maximum discharge it is advertised to be capable of. The power bank itself is the largest you can take on an aeroplane without explicit permission from the airline (This stores 99.5 watt hours of energy, the maximum allowed is 100 watt hours). The bluetooth connected app is good and you can input the battery size of your devices to get an accurate indication of how many times the Power Bank can charge these devices before running flat. This is displayed on the powerbank's screen to view whenever needed. A nice surprise compared to my old Anker 737 is that this allows pass through charging so you can charge the powerbank and also any devices connected to it at the same time. I have just finished charging this power bank from 0 to 100 percent with two cables to get close to the max charging speed of 170 watts, one from a 100 watt charger , and another from my laptop charger which charges at 65 watts. It surprisingly did not get too warm, maxing out at 41c during its torture test, in normal scenarios with one cable I barely see higher than ambient temperature. Using two cables, I managed a charge time from 0 to 94 percent in 32 minutes and 0 to 100 percent in 37 minutes (it slows down to 64 watts charging when almost full). A fully charged power bank will charge your iPhone 15 Pro 5.4 times or a S23 Ultra 3.6 times Definitely recommended if you travel a lot and in need of constant power that can be replenished quickly, but it is expensive (£150)
