Why Choosing a Reputable Brand Matters

Power banks are lithium-powered devices that need to be built with care. A good brand of power bank goes through proper quality control, uses certified battery cells, and follows international safety standards. Cheaper or unknown brands may cut corners, increasing the risk of overheating, short circuits, rapid battery decline, and even fire risks.

A trusted brand also gives you clear information about charging speed, device compatibility, and battery capacity. You know what you’re getting, and it works as expected. In contrast, poorly made products may list inflated specs or deliver lower performance than advertised.

Choosing a recommended power bank brand also means better support. If something goes wrong, you’re more likely to get a replacement, refund, or help from a responsive team.

Built for Safety and Backed in the UK

Anker power banks are designed around MultiProtect, its in-house safety system that protects against overheating, overcharging, short-circuiting, and more.

Flagship battery packs can push 140W in both directions for MacBook Pro-grade charging. There’s also the ultra-compact Nano series for day-to-day phone and accessory top-ups, as well as MagGo snap-on wireless packs. You can expect fast, efficient charging across the entire line-up, no matter your device.

With over 200 million products sold in 146 countries, Anker is more than a familiar name—it’s a proven global leader trusted by both casual users and those with high power demands.

Best Power Banks of 2025

Anker has a wide range of power banks to suit different needs—whether you’re after something compact for everyday use or a high-capacity charger for travel or laptops. Below are the top models worth considering in 2025:

Anker Laptop Power Bank (25,000 mAh, 165W)

The Anker Laptop Power Bank replaces the wall plug on long workdays or multi-device shoots. This 25,000 mAh (90 Wh) block delivers up to 165W across three 100W USB-C outputs and one 33W USB-A.

Two of the USB-C lines are integrated: one fixed cable that doubles as a lanyard plus a retractable stub for quick plug-ins. A 16” MacBook Pro reaches 50% in roughly 33 minutes, and a 100W input pushes the bank itself to 30 % in just 20 minutes.

At 156.9 × 53.9 × 49 mm and 595 g, it’s bag-friendly, and the high-resolution screen shows live battery% as well as power flow. ActiveShield 2.0 monitors temperature millions of times per day for safety.

Best for: freelancers and field technicians who need plug-level power plus spare cables in one block.

What’s good:

• Twin built-in USB-C leads (one retractable) + extra ports = zero cable hunting

• 100W recharge reaches 30% in 20 minutes—handy airport top-ups
• Smart screen gives remaining battery life and input and output wattage

Anker Prime Power Bank (20,000 mAh, 200W)

If you juggle a laptop plus smaller gear, the Anker Prime 20,000 mAh Power Bank is the heavy hitter. Two USB-C ports (up to 100W each) and a USB-A socket share an enormous 200W, enough to push a 16” MacBook Pro to 50 % in roughly 40 minutes while still topping up a phone.

A 100W input reverses the flow, recharging the 20k mAh pack in about 75 minutes. Despite that muscle it stays flight-safe at 72 Wh and measures just 126.9 × 54.6 × 49.7 mm, with a smart LCD for per-port read-outs.

• 72 Wh keeps airline staff happy
• ActiveShield 2.0 manages temps for safer high-wattage use

Anker MagGo Power Bank (10,000 mAh, Slim, Qi2)

The Qi2-certified Anker MagGo Power Bank (10K, Slim) snaps straight onto any MagSafe iPhone and delivers a full 15W wirelessly, helped by an aluminium coil that keeps surface temps under 40°C.

Need wired speed? The USB-C port dishes out—or takes in—up to 30W PD, refilling the pack in about 2.5 hours. Despite doubling the usual magnet-pack capacity, it’s only 14.7 mm thick, 104 × 71 mm across and 200 g, so it still fits a jeans pocket.

Tips for Choosing a Power Bank Beyond the Brand  

Even with a trusted brand like Anker, it’s still worth knowing what to look for based on how and where you’ll use your power bank. Here’s what to consider before buying:

Choose the Right Capacity (mAh vs. Wh)

mAh (milliamp-hours) tells you how much charge a power bank holds. For phones and earbuds, 5,000–10,000 mAh is usually enough.

If you’re topping up tablets or want two to three full phone charges, aim for 15,000–20,000mAh. For laptops, look at 20,000 mAh or more.

But keep in mind that most airlines typically allow power banks up to 27,000 mAh (100 Wh) in hand luggage without restrictions.

Match Output Power to Your Devices

Check that the power bank supports USB-C Power Delivery (PD), especially if you’re charging a laptop, Nintendo Switch, or fast-charging phone. 20-30W is fine for phones, but laptops need 45W or more. For newer tech, support for PD 3.1 and PPS (Programmable Power Supply) gives you faster and cooler charging.

Count the Ports—and Their Specs

Multiple ports are great if you’re charging more than one device at a time. Just be sure the total output won’t slow things down when two or more ports are used together. USB-C is now the standard—avoid banks that rely only on older USB-A ports.

Look for Pass-Through Charging and Fast Refill

Many power banks support pass-through charging, which lets you charge the power bank and your phone at the same time—handy for overnight use. Also check how fast the power bank itself recharges. A 60W input can refill a 20,000 mAh pack in under an hour, while slower inputs might take up to six hours.

Mind Size, Weight and Build

Higher capacity usually means more weight and bulk. If you’re travelling light or need something pocketable for daily use, a slim 10,000mAh bank is ideal. Bigger banks (20,000mAh and up) can weigh as much as a small tablet and take up more bag space. Look for textured or rubberised finishes—they’re easier to grip and won’t slide around on smooth surfaces.

Verify Safety Certifications

Look for labels like CE, UKCA, and UN38.3—these prove the power bank has passed safety and transport testing. It means the battery has been checked for heat resistance, short-circuit protection, shock tolerance and more.

Convenience Touches

If you’re trying to cut down on cable clutter, go for models with built-in USB-C cables—or skip the wires entirely with a Qi2 magnetic battery pack. And instead of relying on four vague blinking lights, a battery with a clear display readout is way more helpful for planning your day.

Conclusion

You don’t need to scroll through endless listings or take a gamble on dodgy brands. Stick to names that consistently deliver—Anker is a solid example. It’s trusted for a reason: reliable performance, smart safety features, and products that fit various needs and actually last. Now that you know which good brand of power bank to trust, it’s time to pick a model that’s made for you, whether that’s laptop-grade power, 25,000 mAh capacity, or snap-on MagSafe ease.

FAQs

Which brand of power bank is the best?

Anker is widely regarded as one of the top power bank brands in the UK, known for its reliable performance, fast charging capabilities, and durable build quality.

How do I choose a power bank?

When selecting a power bank, consider your specific needs and usage patterns. For everyday use, a compact 10,000 mAh power bank is typically sufficient. If you’re planning extended trips or need to charge larger devices like tablets or laptops, a higher-capacity power bank (20,000 mAh or more) would be more appropriate. Look for features such as fast charging Power Delivery support, multiple USB-C and USB-A output ports, and safety certifications to ensure reliable operation.

How many mAh do I really need?

The amount of mAh you need depends on what you’re charging and how often. For casual users, a 5,000–10,000 mAh power bank is perfect for one or two full phone charges. For frequent travellers or those needing to charge multiple devices, 20,000mAh or more offers greater flexibility. Just remember that most airlines allow power banks up to 100 Wh (about 27,000 mAh) in your carry-on without restrictions.
