The 10 Best Portable Laptop Charger Reviewed
1. Anker Power Bank 20,000mah
We put the Anker 20,000mAh Power Bank through its paces, and it’s a solid contender for anyone needing reliable on-the-go power. The large capacity means you can charge your phone multiple times or give your laptop a significant boost. Its build quality feels robust, designed to withstand the rigors of travel without issue.
During testing, I found the dual USB-A ports offered decent charging speeds for older devices, though it’s not the fastest option for modern smartphones. The included USB-C cable is a nice touch, but it’s quite short, which can be a bit limiting if your power bank is on the floor and your device is on a desk.
This power bank is ideal for travelers who prioritize capacity and durability over the absolute fastest charging speeds. It’s a workhorse that will keep your essential gadgets topped up throughout long journeys or busy workdays away from an outlet. However, if you’re looking for rapid charging for your latest flagship phone, you might feel it’s a bit slow.
Real-Life Usage Scenario: Imagine being on a cross-country flight, your laptop battery dwindling during a crucial work session. This Anker power bank, tucked away in your carry-on, provides the lifeline needed to finish that presentation, all while your phone stays charged for entertainment during the flight.

We observed that the multiple USB ports, including USB-C and USB-A, provide excellent versatility for charging various devices simultaneously. While the high wattage is fantastic, the unit does tend to get noticeably warm during intensive charging sessions, which, while not alarming, is something to keep in mind.
This power bank is an excellent choice for professionals who rely on their laptops throughout the day and need a quick, powerful recharge. It’s also great for users with multiple high-power devices that they need to keep juiced up on the go. However, if you only need to charge a smartphone or tablet occasionally, this might be overkill and a bit bulky.

Its 20,000mAh capacity offers a substantial energy reserve, easily enough to provide a full charge to most laptops and several phone charges. The design is sleek and modern, fitting comfortably into a backpack or messenger bag.
During our testing, the 100W USB-C output proved effective for charging my MacBook Pro at a respectable speed, though it wasn’t quite as fast as a dedicated wall charger.

This power bank is ideal for students, business travelers, and digital nomads who need reliable power for their laptops and other devices without being tethered to an outlet. It strikes a good chord between capacity, charging speed, and a manageable form factor. However, if you absolutely need the fastest possible laptop charging, you might want to consider higher wattage options.

I found the triple 100W USB-C ports to be incredibly convenient for simultaneously charging my laptop, tablet, and phone.

This power bank is perfect for extended trips, remote work setups, or anyone who carries multiple power-hungry devices. It offers peace of mind knowing you have a substantial power reserve at your disposal. However, its sheer size and weight might make it less ideal for those who prefer ultra-light travel gear.

5. Asperx Laptop Power Bank 165w 20,000mah
The AsperX 165W Laptop Power Bank is an intriguing option, particularly with its integrated retractable cables. The 20,000mAh capacity provides a good amount of power for laptops and other devices, and the 165W output is certainly impressive for quick top-ups. The aluminum alloy construction gives it a premium feel and a sense of durability.
In testing, the retractable cables were a mixed bag; while convenient for reducing cable clutter, they felt a little flimsy and I worried about their long-term durability. The charging speeds were strong, living up to the 165W claim for compatible devices. However, the placement of the retractable cable ports could be more ergonomic, making them slightly awkward to access at times.
This power bank is best suited for users who value integrated solutions and want to minimize the number of loose cables they carry. It’s a good option for those who frequently charge laptops and other USB-C devices on the go. If cable longevity and ease of access are paramount, you might find the integrated cables a point of concern.
Real-Life Usage Scenario: Picture yourself in a busy airport lounge with limited outlets. You can quickly pull out the integrated USB-C cable from this AsperX power bank to connect your laptop, and another for your phone, without fumbling for separate cables. It offers a streamlined charging experience in a pinch.
Pros
- High 165W output for fast charging.
- Integrated retractable cables reduce clutter.
- Durable aluminum alloy build.
Cons
- Retractable cables feel somewhat flimsy and raise durability concerns.

6. Anker Laptop Power Bank 25,000mah 100w
We put the Anker 25,000mAh laptop power bank through its paces, and it certainly lives up to its reputation for robust charging. The build quality feels solid, with a matte black finish that resists fingerprints reasonably well. Its substantial capacity means you can get multiple charges for most laptops, which is a huge relief when you’re far from an outlet.
The triple 100W output ports are a standout feature, allowing us to simultaneously charge a laptop, a tablet, and a phone at impressive speeds.

Real-Life Usage Scenario: Imagine being at a remote co-working space for an entire day. This Anker power bank kept my MacBook Pro topped up throughout my work session, and I still had enough juice left to recharge my iPad and AirPods before heading home. The peace of mind knowing I wouldn’t run out of power was invaluable.
While it’s a powerhouse, the sheer size and weight of this unit might be a deterrent for those who prioritize ultra-portability. It’s definitely more of a “carry in a backpack” solution than a “pocketable” one.
Pros
- Massive 25,000mAh capacity
- Triple 100W output for simultaneous fast charging
- Durable build quality
Cons
- Can get warm under heavy load
- Somewhat bulky and heavy
7. Juovi Power Bank 45w 20000mah
The JUOVI 45W 20,000mAh power bank offers a compelling blend of capacity and charging speed for its size. When I plugged in my laptop, the 45W Power Delivery was more than adequate to keep it powered during a mid-length work session. The unit itself feels well-constructed, with a pleasant texture that provides a secure grip.
Its compact form factor is a major win, making it easy to slip into a messenger bag or even a larger jacket pocket. The single USB-C PD port is efficient, and I appreciated how quickly it recharged itself when plugged into a wall adapter. However, I found the included USB-C cable to be a bit shorter than I would have liked, which sometimes limited placement options.
Who is this specifically for?: This is ideal for the student or remote worker who primarily uses a single laptop and needs reliable, on-the-go power without the bulk of larger units. It’s perfect for those who need to extend their workday or enjoy a few hours of entertainment away from power sources.
While the 45W is sufficient for many laptops, users with high-performance or gaming laptops might find it a bit slow to charge or even just maintain battery level under heavy load. It’s a solid performer for everyday use, but not for extreme power demands.
Pros
- Compact and lightweight design
- Good 45W PD charging speed
- Decent 20,000mAh capacity
Cons

Its slightly higher 65W output compared to some competitors makes a noticeable difference in charging speed for compatible laptops. The design is sleek and understated, with a matte finish that feels good in the hand and doesn’t attract smudges easily.
The 20,000mAh capacity provides a good balance between portability and power, offering multiple charges for most ultrabooks and mid-range laptops.

This JUOVI power bank kept my work laptop powered through several hours of productivity, and I could also top up my phone and wireless earbuds without issue. It’s the kind of essential item that alleviates battery anxiety on extended trips.

Pros
- Strong 65W USB-C PD output
- Good capacity for its size
- Includes both USB-C and USB-A ports
Cons

The unit feels robust and well-built, with a textured surface that enhances grip and makes it feel secure in hand.
Its compact dimensions are a real highlight, making it one of the more portable options in the 20,000mAh category.

We found its charging capabilities to be exceptional, easily powering demanding laptops and even multiple devices concurrently at high speeds. The build quality is substantial, giving it a premium feel, though its weight reflects its high-capacity nature.
The sheer power on tap is its biggest advantage, ensuring that even power-hungry devices will be well-cared for. The inclusion of multiple ports, including a high-wattage USB-C, provides great flexibility. However, the LED display showing remaining battery percentage, while informative, can be a bit too bright in low-light conditions.

This GENSROCK power bank not only kept my high-performance laptop running at full tilt but also simultaneously charged my external monitor and smartphone, allowing for a full day of productivity without any power worries.

Frequently Asked Questions
How Many Times Can a Portable Charger Recharge My Laptop?
The number of recharges depends on the charger’s capacity and your laptop’s battery size. A charger with a higher mAh or Wh rating will provide more charges. Always check the specific capacities to estimate the recharges accurately.
