Best Portable Power Banks for Phones and Laptops

In today’s hyper-connected world, staying powered on the go is no longer a luxury—it’s a necessity. Whether you’re a frequent traveler, a remote worker, or simply someone who relies heavily on mobile devices, a reliable portable power bank can be a lifesaver.

But not all power banks are created equal. Some are ideal for quick phone top-ups, while others can recharge power-hungry laptops multiple times. With options ranging in size, capacity, and features, choosing the right one can feel overwhelming.

That’s why we’ve rounded up the best portable power banks for both phones and laptops in 2025, based on capacity, charging speed, build quality, and overall value.

1. Anker 737 Power Bank (PowerCore 24K) – Best Overall

The Anker 737 Power Bank, also known as the PowerCore 24K, strikes the perfect balance between high power capacity and portability. With a massive 24,000mAh battery, it can charge a flagship smartphone up to five times or a MacBook Air nearly once and a half.

What sets the 737 apart is its 140W bi-directional USB-C port, which supports Power Delivery 3.1, making it one of the few truly laptop-compatible power banks on the market. This means it can not only charge your devices at lightning speed but also recharge itself in under an hour with the right adapter.

The LCD screen is a thoughtful touch, giving real-time updates on battery percentage, input/output power, and estimated time remaining. It’s slightly heavier than smaller-capacity models, but it remains manageable in a backpack or travel bag.

Best for: Power users who need to charge laptops and phones frequently.
Price range: $$$

2. Zendure SuperTank Pro – Best for Digital Nomads

If you need a power bank that can handle multiple devices without breaking a sweat, the Zendure SuperTank Pro is a standout option. This 26,800mAh power bank features four USB-C ports, three of which support high-speed charging for laptops, tablets, phones, and accessories simultaneously.

The rugged aluminum body and sleek OLED screen give it a professional look, while its intelligent power distribution system ensures efficient energy allocation. It supports up to 100W output from a single port—enough to charge most modern laptops including MacBooks, Surface devices, and USB-C powered Chromebooks.

It’s TSA-compliant for carry-on use, making it ideal for frequent flyers. Though it’s a bit pricier, the durability, performance, and multitasking capability justify the cost.

Best for: Professionals who carry multiple devices and need simultaneous charging.
Price range: $$$$

3. Baseus Blade 100W – Best Slim Laptop Power Bank

For those who want laptop-level power in a more compact form, the Baseus Blade 100W is an excellent pick. With a 20,000mAh capacity and a 100W USB-C output, it delivers a full charge to a MacBook Pro 13” in under two hours—all while fitting snugly in a messenger bag or slim backpack pocket.

The standout feature here is the form factor: it’s thin, wide, and shaped like a small tablet, making it easy to stack with other devices or slip into tight spots. The LED display gives clear readings of input/output levels and remaining battery life.

One drawback is the relatively slower recharge speed unless paired with a strong wall charger, but that’s a minor issue for such a sleek, functional device.

Best for: Users looking for a slim, high-powered backup for laptops and phones.
Price range: $$

4. Nitecore NB20000 – Best Lightweight Option

Weighing only 324 grams (11.4 ounces), the Nitecore NB20000 is a marvel of portable design. Despite its ultralight carbon-fiber construction, it packs 20,000mAh and can push up to 45W via USB-C, enough to charge smaller laptops, tablets, and fast-charge smartphones.

Originally designed with hikers, ultralight travelers, and adventurers in mind, the NB20000 has become popular with everyday users due to its perfect balance of size, weight, and performance. It features USB-A and USB-C ports and can even trickle-charge small devices like fitness bands or wireless earbuds without overheating or cutting out.

It’s not meant for power-intensive laptops like the MacBook Pro 16”, but for ultrabooks or MacBook Air models, it’s more than adequate.

Best for: Ultralight travelers and minimalist tech users.
Price range: $$

5. Omni Ultimate 120W – Best for Heavy-Duty Laptop Users

If you’re running a full-blown workstation on the go, the Omni Ultimate 120W is your best bet. This beast features a 38,400mAh battery and supports 120W DC output alongside 60W USB-C and two USB-A ports. It’s one of the few power banks that can handle DSLR cameras, drones, and gaming laptops in addition to regular consumer electronics.

What really sets the Omni Ultimate apart is its removable battery module and adjustable voltage settings, making it ideal for photographers, filmmakers, engineers, and anyone who needs precise control over charging.

The price is steep and it’s heavier than others on this list, but its modularity and sheer power capacity make it a premium solution for the most demanding users.

Best for: Creatives and field professionals who need serious portable power.
Price range: $$$$$

Final Thoughts: How to Choose the Right Power Bank for You

When selecting the best portable power bank for your needs, the first step is identifying what devices you plan to charge and how often you need to do so. For casual users who want to top up their phone or tablet, a compact 10,000mAh or 20,000mAh unit with moderate output will suffice.

For laptop users, especially those running power-hungry applications, you’ll need at least 20,000mAh with 60W–100W output via USB-C.

Here are a few key tips:

• Check compatibility: Not all USB-C power banks support full Power Delivery for laptops.

• Look for PD and QC labels: Power Delivery (PD) is crucial for laptops, while Quick Charge (QC) helps with fast smartphone charging.

• Display readouts are helpful: Models with LCD or OLED screens provide more useful data than blinking LED lights.

• Consider weight and dimensions: For everyday carry, lighter and slimmer units make a big difference.

• Prioritize brands with safety features: Over-voltage, over-current, and temperature protection are non-negotiable for laptop-grade charging.

Ultimately, the right power bank is one that fits your lifestyle—whether you’re packing light for a day trip, working remotely from a café, or traveling internationally for business. With one of these top-rated models, you’ll never be stuck with a dead device again.
