Best Power Banks for Fast Charging

There's nothing more frustrating than having your smartphone, laptop, or other essential device run out of battery while you're on the move. To avoid that inconvenience, a power bank is an essential companion, keeping your phones, tablets, laptops, and other gadgets powered up wherever you are.

Power banks have come a long way from the bulky, heavy models of the early 2000s. Today's power banks are slim, lightweight, and capable of ultra-fast charging. They often charge multiple devices like phones, tablets, and laptops simultaneously at impressive speeds.

In this guide, we've rounded up the best power banks of 2025, featuring top-performing, fast-charging options for smartphones, laptops, and tablets.

The Best Power Banks for 2025

If you're wondering which models are worth your money this year, we've researched for you. Here are the best power banks for 2025.

1. Anker Prime 27,650mAh Power Bank

Connections: USB-C x 2, USB-A x 1

Weight: 667g

Capacity: 27,650mAh

Think of the Anker Prime 27,650mAh Power Bank as the iPhone 16 Pro Max or Samsung Galaxy S25 Ultra of power banks, big, powerful, and packed with features. With a massive 27,650mAh capacity, it's built for travellers and anyone needing reliable, high-speed charging. It easily earns a spot as one of today's best battery pack options.

During our tests, this unit easily charged a phone, headphones, and a laptop simultaneously. Thanks to its USB-C ports offering up to 100W of power, it fully charged a laptop in under an hour. The Anker Prime also features a handy LED display that shows both the remaining battery life (in minutes) and how long it will take to recharge completely.

Adding to its smart functionality, it comes with Bluetooth connectivity and pairs with the Anker Smart Control app. Through the app, you can track the battery levels of your connected devices, check charging stats, and even optimise performance. If you misplace your power bank, the app can trigger a sound to help you locate it.

2. Anker MagGo Power Bank

Connections: USB-C (20W), Qi2 wireless (15W)

Weight: 250 g

Capacity: 10,000 mAh

Next is Anker MagGo Power Bank, a compact, wireless option built around the new Qi2 charging standard. It uses a ring of magnets to borrow Apple's MagSafe tech for precise alignment. It delivers faster wireless charging speeds of up to 15W for supported devices while remaining backwards compatible with older Qi models, though at slower rates.

The power bank features thoughtful design elements, including a built-in kickstand, a two-way USB-C port on the left edge, and a power button with an LED display on the right that shows the remaining power as a percentage. In testing with an iPhone 14 Pro, it reached a 25% charge in about 20 minutes and held the phone securely in both portrait and landscape orientations. It also supported Apple's StandBy mode while docked, adding convenience for nightstand or desktop use.

While the capacity is decent, it wasn't quite enough to deliver two full wireless charges for the iPhone. However, users may be able to extend usage slightly by switching to wired charging with the included short USB-C cable.

3. Anker Laptop Power Bank

Connections: USB-C x 1, USB-A x 1, built-in USB-C cables x 2

Weight: 594.21 g

Capacity: 25,000mAh

If you're after a combination of style and serious performance, this versatile Anker Laptop Power Bank delivers on both fronts. With a massive 25,000mAh capacity, it can pump out up to 165W when charging two devices simultaneously, or up to 100W to a single device via USB-C.

The sleek, rounded design stands out, complemented by thoughtful extras like a retractable flat 2.3 ft USB-C cable neatly tucked at the top and a clever braided 1 ft USB-C cable that doubles as a convenient carry loop. Its LED display adds further appeal by showing real-time information such as remaining battery life, charging input and output rates, battery temperature, and overall health.

In testing, the power bank fast-charged a wide range of devices, from laptops to smartphones, and reliably powered up to four devices simultaneously. It fully recharges in about two hours and supports pass-through charging, allowing devices to charge while the power bank itself is plugged in.

4. Anker Nano Power Bank

Connections: foldable USB-C connector; USB-C port

Weight: 102g

Capacity: 5,000mAh

For quick, convenient top-ups on the go, the Anker Nano Power Bank is an everyday essential. Small enough to slip into a trouser pocket, it's perfect for recharging a smartphone or earbuds while out and about.

Though minimalistic in design, the Nano's features are well thought out. The fold-out USB-C connector is a standout, plugging directly into the phone. This tidy setup eliminates the need for a cable and avoids the risk of charging slowdowns caused by faulty or underpowered cables. There is also a standard USB-C port on the side for those who prefer using their own cables.

As with any ultra-compact charger, there are a few trade-offs. Its 5,000mAh capacity is enough to boost most smartphones, but it won't quite deliver a full charge for larger devices. That said, it remains a reliable backup for anyone whose phone tends to dip into the red before the day's end.

How to Choose the Right Power Bank for Your Needs?

When picking a good power bank, keep these key specs in mind:

• Capacity (mAh): Indicates how much charge it holds. For example, a 20,000mAh power bank can recharge a 6,000mAh smartphone battery about three times.
• Voltage & Multiple Ports: Check individual and total output limits if several devices are charged simultaneously.
• Wattage: Determines how much power it can deliver. Ensure it matches your device's charging needs; laptops require higher wattage than phones.
• Inputs & Outputs: Most power banks use USB-C or USB-A ports. Some support wireless charging or have built-in Lightning cables for Apple devices.

How Much Lifespan Can You Expect from a Power Bank?

Like all devices with lithium-ion batteries, power banks gradually lose capacity over time. Each full charge and discharge is called a cycle, and most power banks last between 300 and 1,000 cycles, typically enough for 1 to several years, depending on usage. Warranties often reflect this, usually lasting up to two years.

To extend lifespan:

• Avoid letting it drain completely or stay fully charged for long periods.
• Keep it moderately charged when not in use.
• Store it in a cool, dry place, away from heat, cold, and humidity.

How We Test the Best Power Bank

We tested each power bank for charging speed, weight, portability, power capacity, design, and extra features. This included timing how fast it could recharge a phone, tablet, and laptop and checking whether it delivered on its fast-charging claims.

We assessed their size and weight, whether they fit in a pocket or needed a bag, and the number of whole device charges each provided per top-up. Design and durability were also key, along with extras like built-in cables, wireless charging, and displays. Finally, we used them on trips to see how they performed in real-world, on-the-go situations.

FAQs

How many times can a power bank charge my device?

It depends on two things:

• Power bank capacity (mAh)
• Your device's battery size (mAh)

To estimate, divide the power bank's capacity by your phone's battery size. For example, a 10,000mAh power bank can charge a 2,500mAh phone about four times. Generally, most good-quality power banks can recharge a phone two to three times. Always check your device's and power bank's specs for a more accurate figure.

Can a power bank charge laptops and tablets?

Yes, but you'll need a high-capacity power bank with USB-C Power Delivery (PD) support. Look for models with at least 20,000mAh capacity and 65W to 100W output for laptops. These can safely charge most laptops and tablets, giving you several extra hours of use when you're away from a power outlet.

Which is better, 10000mAh or 20000mAh?

It depends on your needs:

• 10,000mAh: Compact, lightweight, budget-friendly, and suitable for 1–2 phone charges.
• 20,000mAh: Bulkier, pricier, but can charge devices multiple times and handle bigger gadgets like tablets.

A 20,000mAh power bank takes longer to recharge but offers more backup power, which is ideal for travel or heavy use.

How long will a 20000mAh battery last?

A 20,000mAh power bank can typically deliver 4–5 full phone charges before recharging. With proper care, it can last over 1,000 charge cycles, equating to around 4–5 years of regular use.
