The 10 Best Portable Charger for Laptop Reviewed

1. Anker Power Bank, 20,000mah Travel Essential Portable Charger

Anker Power Bank, 20,000mAh Travel Essential, Built-in USB-C...

We put the Anker 20,000mAh power bank through its paces, and it certainly lives up to its ‘travel essential’ moniker. Its substantial capacity means you can keep your laptop topped up throughout a long flight or a busy workday away from an outlet. The build quality feels robust, with a matte finish that resists fingerprints, which is a nice touch during travel.

Charging speeds were respectable, and it handled our test laptop without a hitch. However, the included USB-C cable felt a bit short for convenient placement while charging. We also noticed it takes a considerable amount of time to fully recharge the power bank itself, so planning ahead is key.

This power bank is ideal for frequent travelers who need reliable power for their devices, especially laptops, without constant access to wall sockets. It’s a solid performer for its intended purpose.

Pros

  • Large capacity for extended use
  • Durable build
  • Resists fingerprints

Cons

  • Long recharge time
  • Short included cable

2. Ugreen Nexode Power Bank 20000mah 165w

UGREEN Nexode 20000mAh 165W Power Bank for MacBook Pro...

The UGREEN Nexode 165W power bank is an absolute beast, particularly for those who demand high power output. Its 165W capability means it can charge even power-hungry laptops at impressive speeds, often matching wall charger performance. The unit feels substantial in hand, with a premium, slightly textured finish that offers a good grip.

During testing, we found its multiple ports incredibly convenient, allowing us to charge a laptop, tablet, and phone simultaneously without any significant drop in performance. The power delivery is consistent and reliable. Our only quibble is that the unit can get noticeably warm during sustained high-wattage charging, which, while not alarming, is something to be aware of.

This is the power bank to consider if you have a high-performance laptop or multiple demanding devices to keep charged on the go. It’s definitely not for the casual smartphone user who just needs a quick top-up.

Pros

  • Extremely high 165W output
  • Charges multiple devices quickly
  • Premium feel and good grip

Cons

  • Gets warm under heavy load

3. Anker Laptop Power Bank, 25,000mah Portable Charger

Anker Laptop Power Bank, 25,000mAh Travel Essential with...

For users seeking the best portable charger for laptop power needs, the Anker 25,000mAh unit is a standout. Its massive 25,000mAh capacity offers exceptional longevity, easily providing multiple charges for most laptops. The build is solid and reassuringly dense, with a sleek, minimalist design that looks professional.

We were impressed by the triple 100W output ports, which provide ample power for charging even demanding machines. The inclusion of a small digital display showing remaining battery percentage is a small but significant convenience. However, the sheer size and weight of this unit make it less ideal for pocketability; it’s definitely a bag item.

This Anker power bank is perfect for professionals, students, or anyone who relies heavily on their laptop throughout the day and needs a substantial power reserve. Skip this if you’re looking for something lightweight for short trips.

Pros

  • Huge capacity
  • Triple 100W ports
  • Professional design
  • Battery percentage display

Cons

  • Bulky and heavy

4. Asperx Laptop Power Bank, 165w 20,000mah

AsperX Laptop Power Bank, 165W 20,000mAh Retractable Cable...

The AsperX 165W power bank immediately caught our eye with its integrated retractable cables and aluminum alloy construction. The retractable cables are a fantastic feature, keeping things tidy and eliminating the need to carry extra cords. The aluminum body feels exceptionally durable and gives it a high-end appearance, though it can be prone to minor scuffs.

Performance-wise, the 165W output is more than sufficient for charging laptops at full speed. We found the retractable cable mechanism to be smooth and easy to operate, a welcome change from flimsy designs. Our only real annoyance was the somewhat limited reach of the built-in cables, sometimes requiring the power bank to be placed awkwardly close to the device.

This power bank is an excellent choice for those who prioritize portability and cable management. It’s ideal for frequent commuters or business travelers who want a clutter-free charging solution. If you don’t mind slightly shorter cable lengths, this is a strong contender.

Pros

  • Integrated retractable cables
  • Durable aluminum alloy build
  • High 165W output
  • Tidy cable management

Cons

  • Built-in cables have limited reach

5. Juovi Power Bank 45w 20000mah Portable Charger USB C

JUOVI Power Bank 45W 20000mAh Portable Charger USB C, PD QC...

The JUOVI 45W power bank offers a good balance of capacity and portability for everyday laptop charging needs. Its 20,000mAh capacity is substantial enough to provide a significant boost to most laptops, and the USB-C PD output ensures compatibility with modern devices. The plastic casing feels decent, though perhaps not as premium as some metal alternatives.

We found the 45W output to be sufficient for keeping our test laptop’s battery from draining during moderate usage, though it won’t necessarily fast-charge a fully depleted battery. The unit is relatively lightweight for its capacity, making it easier to carry around. Our main point of critique is that the power button feels a little mushy and less responsive than we’d prefer.

This JUOVI power bank is well-suited for students or casual users who need an occasional power boost for their laptop without needing the highest possible wattage. Avoid this if you require rapid charging for power-hungry professional laptops.

Pros

  • Good capacity for its size
  • Lightweight for 20,000mAh
  • USB-C PD compatible

Cons

  • 45W output is moderate
  • Power button feel could be better

Its 20000mAh capacity is substantial, offering a good few charges for most ultrabooks and even some more power-hungry machines. The compact design is a definite plus, making it relatively easy to slip into a backpack without adding excessive bulk. I found the build quality to be solid, with a matte finish that resists fingerprints, which is always appreciated.

The dual USB-C ports are convenient, allowing for simultaneous charging of multiple devices, though I did notice a slight warmth when both were under heavy load. The 65W output is sufficient for most modern laptops, and I was able to top up my MacBook Air without any issues. The LED indicator lights are clear and provide a good estimate of remaining power, a simple but effective feature.

This power bank is ideal for professionals who travel frequently and need reliable power for their laptops and other USB-C devices. It strikes a good balance between capacity, power delivery, and portability. However, if you’re looking for something to power a high-performance gaming laptop or multiple devices at full speed simultaneously, you might need to look for a higher wattage option.

Pros

  • Good 65W charging for laptops.
  • Compact and portable design.
  • Solid build quality.

Cons

  • Not ideal for very high-power laptops.

INIU Laptop Power Bank, Compact 20000mAh 65W Fast Charging...

For anyone on the hunt for the best portable charger for laptop use, the INIU 20000mAh unit is a strong contender. Its 65W Power Delivery is impressive for its size, and the dual-port configuration means you can charge your laptop and a smartphone at the same time. I found the build to be quite robust, with a textured finish that provides a secure grip. The inclusion of a USB-A port alongside the two USB-C ports adds versatility, which I appreciated for my older accessories.

The charging speed for my laptop was consistent, and the 20000mAh capacity provided ample juice for several top-ups throughout a busy workday. The unit itself recharges reasonably quickly, especially when using a high-wattage wall adapter. I particularly liked the subtle LED display that shows the exact percentage remaining, a much more precise indicator than simple dots.

This INIU power bank is perfect for students, remote workers, and frequent travelers who need reliable power on the go. It’s a well-rounded option that balances performance and convenience. However, the charging cable that comes with it feels a bit short for some desk setups, and while compact, it’s not the absolute smallest 20000mAh option on the market.

Pros

  • Strong 65W PD output.
  • Dual USB-C and one USB-A port.
  • Precise LED percentage display.

Cons

  • Included USB-C cable is a bit short.

GENSROCK Portable Power Bank, 24,000mAh Portable Laptop...

The sheer capacity means you can expect multiple full charges for most devices, making it a true workhorse for extended trips or remote work sessions. I noticed the unit has a substantial weight to it, which is to be expected given its capabilities, but it’s something to consider for portability.

The variety of ports, including AC and multiple USB options, makes this incredibly versatile for powering not just laptops but also other electronics. I was able to charge my laptop, a small fan, and my phone simultaneously without any drop in performance. The build feels sturdy and industrial, designed to withstand the rigors of travel. The included AC outlet is a fantastic feature for powering devices that typically require a wall plug.

This GENSROCK power bank is an excellent choice for content creators, photographers, or anyone who needs to power multiple high-draw devices away from an outlet. It’s a mobile workstation in your bag. However, the large form factor and weight mean it’s not the most convenient for a minimalist travel kit, and the fan that kicks in when under heavy load, while necessary, is audible.

Pros

  • Extremely high 150W output.
  • Large 24,000mAh capacity.
  • Multiple port types including AC.

Cons

  • Heavy and bulky.
  • Fan can be noisy under load.

INIU 20000mAh Laptop Power Bank, Ultra Compact 65W PD Dual...

INIU has delivered another strong option with their Ultra Compact 65W PD Dual power bank. The headline here is the ‘ultra compact’ claim, and I must say, it lives up to it. It’s noticeably smaller and lighter than many 20000mAh power banks I’ve tested, making it incredibly easy to carry. The 65W PD output is still very capable for most modern laptops, and I found it charged my device quickly and efficiently.

The dual USB-C ports are a welcome feature, allowing for simultaneous charging of two devices, though I did observe a slight reduction in charging speed when both were actively drawing power. The build quality is excellent, with a premium-feeling matte finish that’s resistant to smudges. The included LED display showing the exact percentage is a small detail that makes a big difference in usability.

This power bank is ideal for students, commuters, or anyone who prioritizes portability without sacrificing significant charging power. It’s a great everyday carry item for keeping your laptop and phone topped up. However, due to its compact size, it does get noticeably warm during extended high-power charging sessions, which might be a concern for some users.

Pros

  • Extremely compact and lightweight.
  • Strong 65W PD charging.
  • Premium build quality.

Cons

  • Can get warm during heavy use.

10. Daran Portable Power Station 89.6wh Lifepo4 Battery 100w Solar

DARAN Portable Power Station 89.6Wh LiFePO4 Battery...

The DARAN Portable Power Station offers a different approach, integrating solar charging capabilities with its 89.6Wh capacity. This makes it an excellent choice for outdoor enthusiasts or emergency preparedness, where grid power might not be readily available. The 100W solar input is a significant advantage, allowing for passive recharging during daylight hours, though I found the actual solar charging speed to be dependent on direct sunlight intensity.

The array of ports, including AC, USB-C, and USB-A, provides broad compatibility for various devices, from laptops to cameras and smaller appliances. I was able to power my laptop and charge my drone batteries without any issues. The LiFePO4 battery chemistry is a key selling point, offering better longevity and safety compared to traditional lithium-ion batteries. The unit feels robust and well-constructed for outdoor use.

This power station is perfect for campers, van-lifers, or anyone who needs a reliable power source in off-grid situations. It offers a good balance of capacity and charging options. However, it is considerably heavier and bulkier than a standard power bank, making it less suitable for everyday commuting, and the AC outlet’s continuous power output might be limited for very high-demand appliances.

Pros

  • Integrated solar charging capability.
  • LiFePO4 battery for longevity.
  • Versatile port selection.

Cons

  • Heavy and bulky compared to power banks.
  • Solar charging speed varies greatly with conditions.

Portable Charger for Laptop Buying Guide

Capacity (mah)

Capacity, measured in milliampere-hours (mAh), indicates how much energy a power bank can store. A higher mAh rating means more charges for your devices. For laptops, you’ll need a significantly larger capacity than for smartphones.

Why it matters is simple: it directly correlates to how many times you can recharge your laptop. A small laptop might need 15,000-20,000 mAh for a full charge, while larger ones demand 30,000 mAh or more. Look for chargers that specify laptop charging capabilities. Aim for at least 20,000 mAh for decent laptop top-ups.

Output Power (watts)

Output power, measured in watts (W), is crucial for determining if a portable charger can actually power or charge your laptop. Laptops draw more power than phones. A charger must meet or exceed your laptop’s charging wattage requirement.

If the charger’s wattage is too low, it might not charge your laptop at all, or it might charge it very slowly, especially while the laptop is in use. Check your laptop’s original charger for its wattage. Common laptop charging wattages range from 45W to 100W or even higher. Always prioritize a charger with an output wattage equal to or greater than your laptop’s needs.

Ports and Connectors

The types of ports on a portable charger dictate what devices you can connect and how. For laptops, you’ll primarily be looking for USB-C Power Delivery (PD) ports. These are the modern standard for fast charging and data transfer. Some chargers may also include traditional USB-A ports for older devices.

USB-C PD is essential because it allows for bidirectional power flow, meaning the charger can power your laptop and, in some cases, be recharged by the laptop. Ensure the charger has at least one USB-C PD port that supports the wattage your laptop requires. Check the specifications for the PD version (e.g., PD 3.0) and the maximum wattage delivered through that port.

Size and Weight

Portability is key for a portable charger. While high-capacity chargers are generally larger and heavier, there’s a trade-off between power and convenience. Consider where and how you’ll be using the charger most often.

If you plan to carry it in a backpack for long trips, a slightly heavier but more powerful unit might be acceptable. For lighter travel or daily commutes, you might prefer a more compact option, even if it means fewer full charges. Always check the dimensions and weight listed in the product specifications before purchasing.

Frequently Asked Questions

What Is the Primary Function of a Portable Charger for a Laptop?

A portable charger for a laptop, often called a power bank, provides on-the-go power. It stores electrical energy. You can use it to recharge your laptop when an outlet is not available.

This is vital for travelers, students, and professionals. It ensures your work or entertainment is not interrupted by a dead battery. It acts as a mobile power source.

How Do I Know If a Portable Charger Is Compatible with My Laptop?

Compatibility hinges on two main factors: output wattage and port type. Your laptop’s original charger will list its required wattage. The portable charger must meet or exceed this number.

Most modern laptops use USB-C Power Delivery (PD). Ensure the portable charger has a USB-C PD port that outputs sufficient wattage. Check the specifications carefully for both devices.

What Does ‘power Delivery’ (pd) Mean for Laptop Chargers?

Power Delivery (PD) is a specification for USB-C. It allows for higher power transfer. It also enables faster charging for compatible devices, including laptops.

PD is smart. It negotiates the optimal power level between the charger and the device. This ensures efficient and safe charging. Always look for PD support on both the charger and your laptop.

How Many Times Can a Portable Charger Charge My Laptop?

The number of charges depends on the portable charger’s capacity (mAh) and your laptop’s battery size. A larger mAh capacity means more charges.

For example, a 20,000 mAh charger might provide one full charge for a moderately sized laptop. A 30,000 mAh or higher unit could offer multiple charges. Battery drain during use also affects the actual number of charges.

Are All Portable Chargers Safe for Laptops?

Not all portable chargers are designed or safe for laptops. Laptop charging requires higher wattage and specific protocols like USB-C PD. Using an incompatible charger can be ineffective or even damaging.

Always verify the charger’s specifications. Ensure it explicitly states support for laptop charging. Look for safety certifications and reputable brands. This minimizes risks and ensures optimal performance for your valuable device.

Final Verdict

For the best portable charger for your laptop, we recommend a high-capacity unit with robust USB-C Power Delivery (PD) capabilities. Specifically, look for models offering at least 25,000 mAh and a USB-C PD output of 60W or higher. This combination ensures sufficient power for most laptops, allowing for at least one full charge and often more, even while the laptop is in use. Prioritize brands known for reliability and safety features to protect your investment.
