The power bank supports charging for laptops, tablets, and phones, and its multiple ports allow you to power several devices at the same time. Dual USB-C input helps reduce the time needed to recharge the power bank itself, compared with many other high-capacity models.

For everyday use, the Anker app provides basic monitoring features such as charging status and device location. Combined with its airline-friendly battery size and practical, well-built design, the Prime 27K is a reliable option for users who need extended power without constant access to wall outlets. It also feels premium and durable—and during Anker's Christmas Sale (2025, December 29 - 2026, Jan 09), buying two eligible items qualifies for 15% off, while purchasing three or more unlocks 20% off, which can make it a better-value choice if you're picking up multiple accessories.

The Anker Laptop Power Bank (25K) is a solid choice for users who need to charge multiple devices on the go, especially laptops. Its 25,000mAh capacity can support up to four devices at once, which works well for setups that include a laptop, tablet, and phone.

A practical highlight is the built-in cabling. One USB-C cable extends up to 2.3 feet, while the shorter one doubles as a carrying strap, helping reduce the number of accessories you need to pack. Along with an additional USB-C port and a USB-A port, the layout makes it easy to connect several devices at the same time without relying on extra adapters.

In terms of charging speed, each USB-C port can deliver up to 100W when used individually, which is enough to fast-charge most laptops. The 165W figure refers to the combined output when multiple ports are in use, allowing a laptop and other devices to charge simultaneously without major slowdowns.

Capacity: 26,250mAh

• Smart Display and App Control
• ActiveShield 4.0 Technology

The Anker Prime Power Bank (26K, 300W) is aimed at users who regularly run power-hungry devices, such as laptops, tablets, and accessories at the same time. With a 26,250mAh (99.75Wh) battery, it stays within airline carry-on limits while offering far more output than typical portable power banks.

Its headline 300W rating refers to total output across all ports, not a single connection. In practice, this means the power bank can keep two MacBook Pros running at full speed when multiple ports are in use. When charging a single laptop with a compatible 5A cable, one USB-C port can deliver up to 140W, enabling fast top-ups for high-performance laptops, while still leaving room to charge other devices simultaneously.

Another standout feature is recharge speed. This is Anker's first power bank to support up to 250W input when both USB-C ports are used together, significantly reducing downtime between uses.

Capacity: 5,000mAh

Flight-Approved: Yes

Key Features:

• Magnetic Snap-On Charging
• Slim Like a Card with Aluminum Finish
• AI Monitoring Chip for Cooling
• Pass-Through Charging

The Baseus Picogo 5K is a budget-friendly magnetic power bank that focuses on simplicity and portability. At just 0.3 inches, it's easy to attach to MagSafe-compatible iPhones without adding noticeable weight. While the 5,000mAh capacity is modest, it's enough for emergency top-ups throughout your day. Although not designed for faster charging or Qi2 wireless charging, the 11N magnetic force is strong enough for steady magnetic charging.

This power bank is best suited for you if you prefer a compact backup rather than a full-day charger. It's further ideal for short trips, errands, or situations where you just need extra power to get home. The lower price point makes it accessible without compromising basic safety features. In fact, it features an AI monitoring chip for cooler charging sessions. If you only need extra power occasionally, this model does the job without overpaying.

The INIU 45W Portable Charger 20,000mAh offers impressive value for its price, especially if you need more capacity without overspending.

Best Power Bank Models Compared Side by Side

Choosing the best power bank starts with understanding how you actually use your devices. Capacity, charging speed, and compatibility matter more than flashy marketing terms. Below are the most important factors to consider before buying.

What to Consider When Choosing the Best Power Bank

Finding the best power banks should match your devices, daily routine, and travel habits to ensure it truly meets your needs. Understanding the key factors below helps you avoid overspending or ending up with a charger that doesn't perform as expected.

1. Capacity (mAh)

Capacity determines how many times you can recharge your devices. A 10,000mAh power bank is usually enough for daily phone use. A 20,000mAh or higher model is suitable for travel or multiple devices. Larger capacity often means more weight, but some portable models remain compact and lightweight despite the high capacity.

2. Charging Speed and Output

Higher wattage means faster charging, especially for tablets and laptops. USB-C Power Delivery is now the standard for quick, efficient charging. Lower-watt models may take significantly longer to recharge devices. Always match wattage to your device's needs.

3. Device Compatibility

Not all power banks support every type of device. iPhones may require MagSafe or Qi2 wireless charging, while laptops need high-watt USB-C ports. Some power banks offer multiple ports for simultaneous charging, which is helpful if you're a heavy gadget user.

4. Portability and Design

Slim models are easier to carry but often have lower capacity. Larger power banks feature more power but are bulky and heavy. Select models that offer a compact and lightweight design while still offering high power. A good design balances comfort and performance

5. Safety Features and Build Quality

A high-quality power bank protects your devices with safeguards like short-circuit protection, overcharge prevention, and temperature control. Cheap or unbranded models may overheat or damage connected electronics. Select a charger with safety features and premium build quality.

6. Extra Features

Some power banks now offer wireless or magnetic charging, multiple ports, retractable cables, or pass-through charging. Others include displays that show remaining battery percentage. Consider which extra features will actually benefit your daily routine.

Final Thoughts

Choosing the best power bank involves understanding your daily charging habits and the devices you rely on most. Whether you need a slim charger for everyday use or a high-capacity model for work and travel, there is a solution that fits your lifestyle. Focusing on capacity, charging speed, and compatibility helps narrow down your options. With the right power bank, staying connected becomes effortless wherever life takes you.

FAQs

Which brand power bank is best?

Anker is the best power bank brand because it consistently delivers reliable performance, strong safety protections, and fast charging across a wide range of devices. Its power banks are built with advanced battery management systems that help prevent overheating, overcharging, and power loss. Anker also supports modern charging standards like USB-C Power Delivery and MagSafe compatibility. This combination of quality, safety, and innovation makes Anker a trusted choice.

What is the best power bank to buy?

The best power bank to buy depends on how you use your devices. For daily phone charging, a compact 10,000mAh fast-charging model is usually enough. If you travel often or charge multiple devices, a 20,000mAh or higher power bank offers better coverage. The ideal choice should balance capacity, charging speed, portability, and compatibility with your phone or laptop rather than focusing on battery size alone.

Which is better 10000 or 20000mAh power bank?

A 10,000mAh power bank is better for everyday use because it is lighter, slimmer, and easier to carry. A 20,000mAh power bank is better for longer trips, heavy phone use, or charging multiple devices. The trade-off is size and weight, as high-power models tend to be bulky. However, most modern power banks, such as those from Anker, offer compact and lightweight models despite the high capacity.

How long will a 20000mAh power bank last?

A 20,000mAh power bank can last several days, depending on your usage. For example, the Anker Prime Power Bank (20K, 200W) can give 3.4 charges to an iPhone 14, 3.4 charges to a Samsung Galaxy S23, and 1 charge to a MacBook Air. The Anker Prime Power Bank (20K, 220W) can also last up to 4.2 days of video streaming for an iPhone 17 Pro Max. Actual results still vary based on charging speed, power loss, and device battery size.

Can I bring a 10000 mAh power bank on a plane?

Yes, you can bring a 10,000mAh power bank on a plane in the United States, as long as it is packed in your carry-on bag. Power banks are not allowed in checked luggage due to safety regulations. Most U.S. airlines and the TSA rules allow lithium-ion power banks up to 100Wh, which easily includes standard 10,000mAh models. You can even bring up to 27,000mAh power bank without exceeding the 100Wh threshold.
