Anker Laptop Power Bank - Top 10 Questions and Answers in 2025
BIKMAN TECHChoosing the right portable charger, especially one powerful enough for your laptop, can feel overwhelming with all the technical specs and features. The Anker Laptop Power Bank, with its high capacity and convenient built-in cables, is a popular option, but you probably have questions! Whether you're considering buying one or already own it and want to understand it better, this post is for you. We've compiled and answered the top 10 most frequently asked questions to help you make an informed decision and get the most out of this powerful device.
1. Will it charge my specific laptop model quickly?
This is often the biggest question! The Anker Laptop Power Bank uses USB Power Delivery (PD) 3.0 technology and can deliver up to 100 Watts (W) through any of its USB-C outputs (including the built-in cables).
This means it’s powerful enough to charge most modern laptops that use USB-C for power, including demanding models like the MacBook Pro 16-inch, Dell XPS 15, HP Spectre x360, and many others requiring up to 100W. Anker officially lists compatibility with MacBooks and other laptops.
Important Note: While capable of 100W, some user feedback suggests that under very heavy, continuous load (like intensive gaming or video editing while charging), the power bank might reduce its output speed (throttle) to manage heat, especially as its own battery level drops. It works excellently for most charging scenarios, especially for laptops needing 65W-90W, but keep this in mind for sustained peak performance needs.
2. How many times can it really charge my devices?
The advertised capacity is 25,000mAh (milliamp hours), but a more practical measure is its energy rating: 90Wh (Watt-hours). This number helps estimate real-world charges more accurately.
Keep in mind that some energy is always lost during charging (usually 25-40%). Based on its 90Wh capacity and typical efficiency:
| Device Type | Estimated Charges |
|---|---|
| Laptops | Roughly one full charge for a laptop with a medium-sized battery (around 50-60Wh). Larger laptops (80Wh+) will get significantly less than a full charge. |
| Smartphones | Around 3-4 full charges for a large smartphone like an iPhone 15 Pro Max or Samsung Galaxy S24 Ultra. |
| Tablets | An iPad Pro might get around 1.5 to 2 charges. |
These are estimates – actual results depend on your device’s battery size and charging efficiency.
3. How does it handle charging multiple devices at once?
This power bank shines here with a massive 165W total maximum output. It has four outputs: two built-in USB-C cables, one separate USB-C port, and one USB-A port.
- Each USB-C output can deliver up to 100W individually.
- The USB-A output can deliver up to 33W.
- The power bank intelligently manages power distribution so the total output doesn’t exceed 165W.
This means you can confidently charge multiple devices simultaneously, even two laptops (e.g., one pulling 100W and another 65W, or two drawing around 80W each), without issue.
4. How long does it take to recharge the power bank itself?
The Anker Laptop Power Bank can recharge impressively fast – taking approximately 2 hours to go from empty to full.
However, there’s a catch: you need a 100W USB-C PD wall charger to achieve this speed. This powerful charger is not included in the box, so you’ll need to purchase one separately if you don’t already own one. Using a less powerful charger will take significantly longer.
5. Can I take this power bank on an airplane?
Yes! The Anker Laptop Power Bank is airline compliant for carry-on luggage.
Its energy capacity is 90Wh, which is safely under the typical 100Wh limit set by the TSA, FAA, and most international airlines for lithium-ion batteries taken in carry-on luggage. Anker explicitly confirms this type of power bank meets these requirements. Remember, power banks must always be carried in your carry-on bag, never in checked luggage.
6. How big and heavy is it? Is it truly portable?
Portability is key for a power bank. Here are the specs for this model:
| Specification | Details |
|---|---|
| Dimensions | 15.7 x 5.4 x 4.9 cm (approx. 6.2 x 2.1 x 1.9 inches) |
| Weight | 595 grams (approx. 21 oz or 1.31 pounds) |
It’s definitely not pocket-sized. It’s similar in weight to other high-capacity laptop power banks but might feel slightly more compact due to the integrated cables saving space. It’s designed to be carried in a backpack, laptop bag, or larger purse where substantial backup power is needed for travel or work away from outlets.
7. Are the built-in cables useful and durable?
A major selling point is the two integrated USB-C cables:
- One short lanyard cable (approx. 11.8 inches / 30 cm) – doubles as a carrying handle.
- One retractable cable extending up to 2.3 feet (approx. 70 cm).
This means you might not need to carry separate USB-C cables. The retractable cable offers decent length for charging nearby devices. Anker states they’ve tested the cables for durability (thousands of bends/retractions). While convenient, the long-term durability of retractable mechanisms is something to consider, though initial user feedback appreciates the tidiness.
8. Does it support pass-through charging?
Yes, this Anker Laptop Power Bank supports pass-through charging. This allows you to charge your devices connected to the power bank while the power bank itself is being recharged.
Key Limitation: Pass-through only works if the wall charger providing power to the power bank delivers 20W or more. Also, the power bank prioritizes its own recharge; if your devices try to draw more power than the wall charger supplies, the output to your devices will be limited.
9. Does it fast-charge phones and other gadgets well?
Absolutely. Beyond laptops, this power bank is equipped to fast-charge a wide variety of devices thanks to supporting multiple charging standards:
- PD 3.0 (Power Delivery): For iPhones, Pixels, iPads, Nintendo Switch, etc.
- PPS (Programmable Power Supply): Crucial for optimal fast charging on recent Samsung Galaxy phones.
- QC 3.0 (Quick Charge): For many Android devices.
- SCP / AFC / UFCS: Other standards used by various manufacturers.
So, whether you have an iPhone, Samsung, Google Pixel, tablet, or compatible gaming device like the Steam Deck, this power bank should provide fast charging speeds.
10. Is it worth the price compared to other options?
This Anker Laptop Power Bank offers a compelling package with its high capacity (90Wh), strong total output (165W), powerful single-port output (100W), and especially the convenience of integrated cables.
How it compares generally within the Anker lineup and market:
- Models without integrated cables might offer slightly better sustained performance under heavy load or come at a lower price point for similar core specs.
- Higher-end "Prime" series Anker power banks offer more features (like smart app connectivity, higher 140W single-port output using PD 3.1) but are usually larger, heavier, more expensive, and lack integrated cables.
The Verdict: This Anker Laptop Power Bank is a great choice if you highly value the convenience of not carrying extra cables and need a powerful, versatile charger. If maximum sustained performance or the absolute lowest price is your priority, other models (with separate cables) might be more suitable. Consider your specific needs and budget.
We hope these answers help you understand the Anker Laptop Power Bank better! It’s a feature-packed device designed to keep your tech powered up on the go.
