Anker Prime 27,650mAh Power Bank (250W) Review

The laptop power bank that actually replaces wall sockets

If you are a founder, remote worker, or someone who carries a laptop and two phones every day, you already know this pain: the one free socket in a cafe is too far, the meeting room has no extension, the airport lounge is crowded. A normal 10,000mAh power bank keeps your phone alive, but your laptop still dies at the worst possible moment.

The Anker Prime 27,650mAh Power Bank (250W) is built exactly for that nightmare. It is basically a tiny, travel friendly power station in the shape of a soda can, with enough power to fast charge a 16 inch MacBook Pro and still top up your phone and tablet on the side. 

I have gone through the specs, third party tests, and regional pricing to see if this is the right “do it all” power bank for power users in 2025. Here is the deep dive.

Quick verdict

If you want the one power bank that can handle your laptop, tablet, and phone together without begging for wall sockets, this is one of the best airline friendly options you can buy right now. It is expensive, heavy, and absolutely overkill for casual users, but for founders, creators, and gamers who live on the move, it can pay for itself in convenience very quickly.

Buy it if:

  • You frequently work on a laptop away from power
  • You travel by air and want something under the 100Wh limit
  • You need real 140W USB PD 3.1 charging for MacBook Pro or similar laptops
  • You like having charging stats and tracking through an app

Skip it if:

  • You only need to charge a phone and maybe earbuds
  • You want something pocketable and ultra light
  • Your budget is tight and you do not really need laptop level charging

Design and build quality

Anker has taken a very “premium gadget” approach to the Prime series, and this 27K, 250W model reflects that. It looks more like a small desktop accessory than a cheap plastic power bank.

  • The footprint is close to a thick soda can standing on its side. It easily fits into a sling bag or backpack tech pouch, but not your jeans pocket.
  • The body feels solid, with dense weight and high quality plastics and metal accents. This is good for durability, but you will definitely feel the 665 g in your bag. 
  • The front hosts the three ports and a bright color LCD screen that shows remaining percentage, estimated time to empty or full, and real time wattage. That display is more helpful than it sounds when you want to see, for example, “Is my laptop actually drawing 90W or just 45W right now?” 

Compared to typical 20,000mAh bricks, the Anker Prime looks and feels more like a mini power appliance. On a desk, it does not feel out of place beside a MacBook and an iPhone.

Ports, power and standards

On paper, this thing is a monster.

  • Total output up to 250W shared across the two USB C and one USB A port
  • C1 and C2 USB C ports support USB Power Delivery 3.1 with up to 140W output for a single device, enough to feed the latest 16 inch MacBook Pro close to its full charging rate 
  • USB A port supports high current 5V and other fast charge profiles for older phones, accessories, and random devices (TWS cases, routers, etc.) 

In real life, reviewers have confirmed that the Anker Prime 27K can:

  • Charge a 16 inch MacBook Pro from near empty to almost a full charge at high speed
  • Give a 14 inch MacBook Pro a full charge
  • Charge a 13 inch MacBook Air about 1.25 times
  • Charge a modern iPhone roughly 4 times

Macworld and Android Central both reported performance in that range, along with stable 140W charging when the laptop supports PD 3.1. 

For power users, that means you can turn a dead MacBook into a “full working day plus” with just this one brick, without touching a wall socket.

Real world multi device performance

The big marketing promise is “250W multi device fast charging”. That is not just a line. Under the right conditions:

  • C1 can maintain up to 140W to a laptop
  • C2 can deliver solid fast charging to a second device (tablet, phone, handheld console)
  • The USB A port can output enough to fast charge a typical smartphone

Anker’s own materials and BD retailers specifically mention scenarios like charging a 16 inch MacBook Pro to 50 percent in around 28 minutes, while still powering other devices. 

This is where the Prime 27K starts to feel like a desk replacement for a multi port charger:

  • At a client meeting, you can plug in your laptop, your phone, and maybe your colleague’s phone. No hunting for extension cables.
  • On a long flight, you can run a laptop plus Steam Deck or Nintendo Switch and still keep your phone alive.

Just remember that 250W is the combined ceiling. If you load all three ports with heavy devices, the power bank will split the available power, and some devices may not hit their absolute maximum speed. In practice though, it is still much faster than normal power banks.

Smart app and LCD: Useful or gimmick?

The Anker Prime series talks a lot about “smart app control”. With this power bank:

  • You can pair it with the Anker app via Bluetooth.
  • The app shows real time power input and output, remaining capacity, charge time, and some history.
  • You can trigger a sound alert to help you locate the power bank if you misplaced it in a bag or room. 

Is it essential? Probably not. But for a certain type of user it is genuinely handy:

  • If you are running multiple devices and want to know how much your laptop is actually pulling compared to your phone.
  • If you have several Anker Prime devices and want a single dashboard for them.
  • If you often forget gadgets in meeting rooms and the sound alert saves you once or twice.

The LCD on the device itself is, in my opinion, far more useful day to day. That at a glance view of “XX percent, XX minutes left, XX watts out” makes the device feel like a mini UPS for your bag.

Safety, heat, and reliability

Anker is one of the more conservative brands around battery safety. The Prime 250W 27K uses what they call ActiveShield 2.0, which monitors temperature and power hundreds of times per second and adjusts output to keep things within safe ranges. 

In independent reviews:

  • The power bank warms up under heavy 140W laptop charging, especially when also fast charging a phone, but remains within reasonable thermal limits. 
  • No major voltage drop spikes or worrying behavior show up when power draw changes.

This is important if you are connecting expensive laptops and tablets. You want the power to be aggressive but predictable, and the Prime 27K does deliver that.

Travel and airline friendliness

Capacity is 27,650mAh at roughly 3.6 to 3.8V, which is about 99.54Wh. That number matters because:

  • Most airlines and regulators set a 100Wh upper limit for power banks in carry on baggage without special approval.
  • This Anker model intentionally sits just under that limit, so you can fly with it in your backpack. 

For founders or remote workers who travel a lot between Dhaka, Dubai, Singapore, etc., this makes it a very safe choice. No drama at security as long as it is in your cabin bag and not in checked luggage.

The only downside is weight. Nearly 700 g (with cable) is noticeable if you are chasing ultra light travel. If you mostly travel with a 13 inch laptop and do not need 140W charging, a smaller 20,000mAh, 100W class power bank may be a better balance.

Charging the power bank itself

Big capacity is great, but only if the bank can recharge quickly.

According to Anker and several BD retailers: 

  • The Prime 27K supports up to 170W USB C input when both USB C ports are used as input with a high power charger.
  • Under ideal conditions, it can fully recharge in around 37 to 43 minutes.
  • There is also an optional 100W charging stand that uses pogo pins on the bottom of the power bank. Drop it on the stand, and it charges like a mini dock while also working as a desktop charger. 

In realistic home or office setups, you will probably use a single 100W or 140W GaN charger. With that, expect roughly 1 hour plus for a full charge from near empty, which is still impressive for 27,650mAh.

Price and availability in Bangladesh

Globally, the Anker Prime 27,650mAh 250W Power Bank launched at around 129 to 199 USD depending on market and bundle. 

In Bangladesh, pricing (as of late 2025) moves around depending on seller and stock:

  • Some retailers list it around 19,900 BDT
  • Others show prices up to 21,000 to 22,000 BDT or more, often with small discounts. 

This is clearly a premium product. There are many 20,000mAh, 30W to 65W power banks between 2,000 and 6,000 BDT, but they cannot power a MacBook Pro at 140W or charge three big devices at speed.

If you are only charging a phone, this is overkill. But if you calculate the cost against:

  • Multiple separate chargers
  • Lost productivity when your laptop dies in transit
  • The convenience of always having a “portable wall socket” in your bag

then for serious users, that 20K BDT territory can be justified.

Who is this for?

Founders and product people on the move

If you are bouncing between offices, co working spaces, client meetings, and airports, this device makes a lot of sense:

  • Charge your laptop while presenting or taking notes, without hunting for a free plug.
  • Keep your phone and second device topped up at the same time.
  • Survive power cuts or load shedding during critical calls.

Creators, editors, and gamers

  • Video editors or designers working from a cafe can pull heavy loads on a MacBook Pro without worrying about power.
  • Steam Deck, Nintendo Switch, or gaming laptop users can extend play sessions significantly during travel.

Tech enthusiasts and early adopters

If you enjoy stats, graphs, and the idea of a “smart” battery with app control, this is the kind of gadget you will love, simply because it feels like carrying a tiny power station.

Where it falls short

Even great products have trade offs.

  1. Weight and bulk
    • At around 665 g, this is not a casual everyday carry for minimalists. It is a bag gadget, not a pocket device.
  2. Price
    • Around 20K BDT is a serious investment for a power bank, especially if you do not truly need laptop level charging.
  3. Only three ports
    • For 250W, some users may wish it had four ports, especially if they often charge a laptop, phone, tablet, and accessories together.
  4. Dock sold separately
    • The 100W stand that turns it into a great desk charger is not included. If you also buy that, the total cost goes even higher. 
  5. Smart app is nice, but optional
    • The app is cool, but after the initial excitement, many users may mostly rely on the built in display. If you never use the app, you are paying for a feature you do not fully exploit.

Anker Prime 27,650mAh (250W) vs cheaper options

If you are deciding whether to go for this or a mid range power bank, here is the simple logic:

Choose the Anker Prime 27K 250W if:

  • Your laptop supports USB C charging at 65W to 140W
  • You actually plan to run your laptop on battery plus this bank for several hours
  • You travel a lot and need airline compatible, high power charging
  • Time saved during work sessions is more valuable to you than saving 10K BDT upfront

Choose a cheaper 65W or 100W 20,000mAh bank if:

  • Your main device is a phone plus maybe a tablet
  • You only occasionally top up a light USB C laptop
  • You prioritize weight and price more than raw power

Final verdict for techinsighter.com readers

The Anker Prime 27,650mAh Power Bank (250W) feels like the natural progression of what a “power bank” should be for serious users in 2025. It combines:

  • True laptop class USB PD 3.1 power
  • Enough capacity to turn a dead MacBook into nearly a full working day
  • Smart app control and an excellent LCD
  • Airline friendly capacity just under 100Wh

Yes, it is heavy. Yes, it is expensive. But it is also one of the few products that can genuinely change how you think about working away from a wall socket.

For founders, product managers, engineers, and creators who live between meetings, flights, and co working spaces, the Anker Prime 27K 250W is not just a gadget. It is peace of mind in your backpack.

If you only need to keep your phone alive, look elsewhere.

If you want your bag to carry its own silent power outlet, this is absolutely worth a serious look.
