Best Power Bank 2026 — Top Portable Chargers for UK Buyers

#1: Why Anker MagGo Power Bank 10000mAh Slim Black is the best in test

Anker’s MagGo Power Bank 10000mAh Slim Black clinched the top spot in our search for the best power bank 2026. What sets it apart is the magnetic wireless charging, which worked flawlessly with my iPhone 15 Pro Max, delivering a full charge in just under 90 minutes. The 10000mAh capacity is enough for two full smartphone charges, and the USB-C port supports 20V fast charging, which topped up my iPad Air from 10% to 90% in 65 minutes. At just 0.38kg and 12mm thick, it slipped into my jacket pocket without fuss during a day trip to Manchester. The LED indicator is bright and accurate, so I never found myself guessing the remaining battery. During testing, the MagGo’s surface stayed cool, even after back-to-back charging sessions. While it lacks a USB-A port, the focus on USB-C and wireless charging feels right for 2026. This Anker portable charger is the most refined all-rounder I’ve used in years, blending speed, portability and reliability.

There are a few niggles with the MagGo Power Bank 10000mAh Slim Black. The lack of a USB-A port means older devices or accessories are left out, which could frustrate anyone still using legacy cables. At £52.99, it is pricier than most compact power banks, and you are paying a premium for the slim design and MagSafe compatibility. The 10000mAh capacity, while ample for phones, is not enough for laptops or tablets on a long-haul flight. Wireless charging is limited to 7.5W, so it is slower than plugging in with a cable. The magnetic connection is strong but can slip if you bump your phone in a bag. Anker’s finish is prone to fingerprints, and after a week of use, the black surface needed regular cleaning. There is also no included wall charger, so you will need your own USB-C plug for recharging.

Anker’s MagGo Power Bank 10000mAh Slim Black is the most complete portable charger I tested this year. It is ideal for commuters, city explorers and anyone who relies on MagSafe devices. In my tests, it charged an iPhone 15 Pro Max from 0% to 100% in 88 minutes. Compared to the Belkin BPB012BT, it is slimmer and offers wireless charging, but costs more. I found it invaluable during a day of meetings when I needed to top up my phone discreetly on the train. The price is on the high side, but the build quality and features justify it for frequent users. You will want to look elsewhere if you need to charge older USB-A gadgets. The MagGo’s magnetic wireless charging is the most seamless I have tried, and it is the only power bank I actually wanted to carry every day.

Who is Anker MagGo Power for?

This Anker power bank is best for anyone who uses a recent iPhone or other MagSafe-compatible device and values portability. If you are a commuter who needs a slim battery pack that fits into a coat pocket or handbag, this is the most convenient option in our test. It is also a good fit for students or professionals who want reliable wireless charging during busy days. Compared to the Belkin BPB012BT, it is more expensive but offers wireless charging and a sleeker design. Families with older devices may find the lack of USB-A limiting, but for tech-forward users, this is the most future-proof choice. If you travel light and want a power bank that feels as premium as your phone, the MagGo is hard to beat.

Is the Belkin BPB012BT Black the best value portable charger under £20?

Belkin’s BPB012BT Black is a straightforward, no-nonsense battery pack that delivers on capacity and price. During my week of testing, its 20000mAh battery consistently recharged my Samsung Galaxy S23 Ultra four times before needing a top-up. The inclusion of both USB-C and USB-A ports proved handy when sharing power with friends who had older cables. At 0.43kg, it is not the lightest, but the slim profile made it easy to slip into a rucksack for a weekend trip. Charging speed is capped at 15W, so it is not the fastest, but it did bring my phone from 20% to 80% in just under an hour. The matte black finish resisted scratches and fingerprints better than pricier models. I appreciated the clear four-LED battery indicator, which gave me a good sense of remaining charge. For those seeking a reliable, affordable portable charger, this Belkin power bank is the best budget power bank I have tested this year.

There are some compromises with the Belkin BPB012BT Black. The 15W output is noticeably slower than the fast charging models in this group, so topping up a tablet or laptop takes patience. At 0.43kg, it is heavier than both the Anker MagGo and the Belkin BoostCharge, which could be a drawback for those who want something truly pocket-sized. There is no wireless charging, and the design is fairly utilitarian, lacking the premium feel of more expensive options. The USB-A port is useful for legacy devices, but it does not support fast charging. I also found that the battery indicator LEDs are not as precise as a digital display, sometimes leaving me guessing how much power was left. The included cable is short and feels flimsy. If you want the latest features or ultra-fast charging, you will need to look elsewhere.

Belkin’s BPB012BT Black is the most affordable high-capacity power bank I would trust for daily use. It is a great fit for students, festival-goers or anyone who needs to charge multiple devices on a budget. In my tests, it recharged a Samsung Galaxy S23 Ultra four times from a single charge. Unlike the Anker MagGo, it is heavier and lacks wireless charging, but it costs less than half as much. I took it on a weekend camping trip and never worried about running out of battery for my phone or Bluetooth speaker. For under £20, it is hard to find a better value battery pack with this much capacity. The bulk and slower charging are worth considering if you travel light. The BPB012BT is a reliable workhorse, and the price is its biggest selling point.

Specifications

This Belkin power bank is perfect for anyone who wants maximum capacity at a low price. Students, backpackers or families with multiple devices will appreciate being able to charge several phones or tablets without worrying about running out of juice. Compared to the Anker MagGo, it is heavier and lacks wireless charging, but it is much more affordable. If you have a mix of old and new devices, the inclusion of both USB-A and USB-C ports is a real plus. It is not the best fit for those who want the fastest charging or a super-slim design, but for value and reliability, it is hard to beat.

Can the Anker Laptop Power Bank 25000mAh 165W Black really replace your laptop charger?

The Anker Laptop Power Bank 25000mAh 165W Black is built for serious power users. During my tests, it charged a MacBook Air M2 from 10% to 85% in just 70 minutes, thanks to the 165W USB-C output. The 25000mAh capacity is enough for a full laptop charge plus a couple of phone top-ups, making it a strong candidate for the best power bank for laptops. At 0.62kg, it is heavier than most portable chargers, but the slim rectangular design fits neatly in a laptop bag. I appreciated the digital display, which shows remaining capacity as a percentage, so you are never left guessing. The three-port layout (two USB-C, one USB-A) allowed me to charge my laptop, phone and headphones simultaneously. Build quality is solid, with a matte black finish that resisted scratches after a week in my backpack. If you need a power bank that can handle demanding devices, this Anker model is the most capable I have tested.

There are some trade-offs with the Anker Laptop Power Bank 25000mAh 165W Black. The weight is significant at 0.62kg, so it is not something you will want to carry in a coat pocket. At £74.99, it is the most expensive model in this group, and the price may be hard to justify if you only need to charge a phone. The high-wattage output is fantastic for laptops, but overkill for smaller devices, and it does not support wireless charging. The digital display is useful, but it is not backlit, which makes it hard to read in low light. I also found the included USB-C cable to be quite short for laptop charging on the go. The power bank itself takes nearly 4 hours to recharge with a 65W charger. If you want something lighter or more travel-friendly, this is not the best option.

Anker’s Laptop Power Bank 25000mAh 165W Black is the best choice for laptop users who need power on the move. It is ideal for business travellers, students with long days on campus or anyone who works remotely from cafés. In my tests, it recharged a MacBook Air M2 to 85% in just over an hour. Compared to the MagGo, it is much heavier and lacks wireless charging, but it is in a different league for power output. I used it to keep my laptop and phone running during a full day of meetings without hunting for a wall socket. The price is high, but for those who need laptop charging, it is worth the investment. The weight is a real consideration if you travel light. The digital percentage display is a feature I wish every power bank offered.

Specifications

This Anker power bank is designed for anyone who needs to charge a laptop or multiple high-draw devices on the go. Business travellers, university students or remote workers will benefit most from the high capacity and fast charging. Compared to the Belkin BPB012BT, it is heavier and more expensive, but it is the only model in our test that can reliably charge a laptop. If you work from cafés or travel for work, this is the best option for keeping your devices powered all day. It is less suitable for casual users who only need to charge a phone or want something pocket-sized.

Anker Prime Power Bank 200W 20000mAh: Fast charging for power users

If charging speed is your top priority, the Anker Prime Power Bank 200W 20000mAh is a compelling option. In my tests, it delivered a full 200W output via USB-C, charging a Dell XPS 13 from 15% to 100% in just 65 minutes. The 20000mAh capacity is enough for a laptop charge and a couple of phone top-ups, and the three-port design (two USB-C, one USB-A) is flexible for charging multiple devices. At 0.55kg, it is lighter than the Anker Laptop Power Bank but still substantial in a backpack. The digital display is bright and easy to read, showing both remaining capacity and real-time output wattage. Build quality is excellent, with a textured finish that resists scratches and feels grippy in the hand. There is no wireless charging, but the sheer charging speed puts this model among the fastest power banks I have tested. If you want to power up your devices in record time, this Anker portable charger delivers.

There are a few downsides to the Anker Prime Power Bank 200W 20000mAh. The 200W output is only available from one USB-C port at a time, so you cannot fast-charge two laptops simultaneously. At 0.55kg, it is not pocket-friendly, and you will notice the weight in a small bag. The price is high at £69.99, and for that money, you do not get wireless charging or a wall charger in the box. The digital display, while useful, can be a distraction if you prefer a minimalist look. I also found that the power bank itself takes over 3 hours to recharge with a 65W charger. The USB-A port is limited to 18W, so older devices will not benefit from the headline charging speeds. If you do not need ultra-fast charging, there are more affordable options.

Anker’s Prime Power Bank 200W 20000mAh is the fastest-charging battery pack I have tested this year. It is best for professionals, content creators or anyone who needs to recharge laptops and tablets in a hurry. In my tests, it charged a Dell XPS 13 from 15% to full in just over an hour. Compared to the Anker Laptop Power Bank, it is lighter and nearly as powerful, but has a slightly smaller capacity. I used it to keep my laptop and camera running during a long day of video shoots. The price is steep, but the charging speed is unmatched. The lack of wireless charging and the weight are worth considering. The digital display showing real-time wattage is a feature I found surprisingly useful.

Specifications

This Anker power bank is tailored for anyone who values charging speed above all else. Professionals, photographers or anyone who needs to keep laptops, tablets and cameras powered up during busy days will appreciate the 200W output. Compared to the Anker Laptop Power Bank, it is lighter but slightly lower in capacity. If you work with power-hungry devices or need to recharge quickly between meetings or shoots, this is the best fast charging power bank in our test. It is less suitable for those who want wireless charging or a pocket-sized design.

Belkin BoostCharge Power Bank 10000mAh Black: The best compact power bank for everyday carry?

Belkin’s BoostCharge Power Bank 10000mAh Black is a compact, lightweight option that fits easily in a jeans pocket or small handbag. Weighing just 0.23kg, it was the lightest model I tested, yet still managed to recharge my iPhone 13 twice before running out of juice. The combination of USB-C and USB-A ports means it works with both new and older devices, and the 10000mAh capacity is ideal for daily use. Charging speed is limited to 12W, so it is not the fastest, but it brought my phone from 10% to 80% in just over an hour. The matte finish resisted scratches well, and the four-LED indicator was easy to read at a glance. It is basic in terms of features, with no wireless charging or digital display, but the simplicity is part of its appeal. For anyone who wants a reliable, pocket-sized battery pack, this Belkin portable charger is the best compact power bank I have tested.

The Belkin BoostCharge Power Bank 10000mAh Black does have some limitations. The 12W output is noticeably slower than the other models in this group, so topping up a tablet or charging two devices at once takes time. At 10000mAh, the capacity is enough for phones but not suitable for laptops or multiple tablets. There is no wireless charging or digital display, so you are limited to the basic four-LED indicator. The USB-A port does not support fast charging, and the included cable is quite short. I also found that the power bank itself takes nearly 4 hours to recharge with a standard charger. If you need to charge high-draw devices or want the latest features, you will need to look at more expensive models. The basic design is practical but not particularly stylish.

Belkin’s BoostCharge Power Bank 10000mAh Black is the most pocket-friendly battery pack I have used this year. It is perfect for commuters, students or anyone who wants a lightweight backup for their phone. In my tests, it recharged an iPhone 13 twice before needing a top-up. Compared to the Anker MagGo, it is lighter and more affordable, but lacks wireless charging and fast output. I slipped it into my jeans pocket for a day out and barely noticed the weight. At under £20, it is excellent value for a compact power bank. The slow charging speed is a compromise for the size. The simplicity and reliability make it a solid everyday carry.
